A HISTORY OF THE BRITISH SEA-ANEMONES AND CORALS. WITH COLOURED FIGURES OF THE SPECIES AND PRINCIPAL VARIETIES. PHILIP HENRY GOSSE, F.R.S. LONDON: VAN VOORST, PATERNOSTER ROW. 1860. PREFACE. In TrritiBg the following pages, I have laboured to produce such a " History of the British Sea- Anemones and Corals," as a student can work with. Having often painfully felt in studying works similar to the present, the evil of the vagueness and con- fusion that too frequently mark the descriptive portions, I have endeavoured to draw up the characters of the animals which I describe, with distinctive precision, and with order. It is said of Montagu that, in describing animals, he constantly wrote as if he had expected that the next day would bring to light some new species closely resembling the one before bim ; and therefore his diagnosis can rarely be amended. Some writers mistake for precision an excessive minuteness, which only distracts the student, and is after all but the portrait of an individual Others describe so loosely that half of the characters would serve as well for half-a-dozen other species. I have sought to avoid both errors : to make the diagnoses as brief as possible, and yet clear, by seizing on such characters, in each case, as are txxdj distinc- tive and discriminative. Further to aid the student, I have given the characters in a regular and definite order, so that he may at a glance compare species with species, or genus with genus, La their several parts and organs. In this I have received little aid — I may say almost literally none — from my predecessors. The " History of British Zoophytes " VI PREFACE. by Dr. Johnston has hitherto been the EngUsh naturalist's only guide to the study of these creatures ; and notwithstanding the value of this work in many points, the almost utter worthless- ness of their specific characters has been often confessed. That excellent zoologist lived on a coast where the Anemones are feebly represented ; and hence his personal acquaintance with species was very small, or the result would doubtless have been different. The elaborate " Histoire Naturelle des Coralliaires " of M. Milne-Edwards is liable to the same objection, A work of immense research, labour, and patience, it bears evidence in every page of being the produce of the museum and the closet, not of the aquarium and the shore. With those species which possess no stony skeleton, the learned author evidently had no acquaint- ance, — or next to none ; — and hence he has merely reproduced the words of his authorities in all their vagueness ; while the distribution of the species into genera and families appears so full of manifest error to one personally familiar with the animals in a living state, that I have not attempted to follow his arrangement. I have been compelled, therefore, to draw up the characters of my subjects de novo ; and in doing so I have resorted to nature itself; I have studied the living animals. For the last eight years I have searched the most proUfic parts of the British shores, — the coast of Dorset, South and Korth Devon, and South Wales ; and have moreover, as the following pages show, had poured into my aquaria the productions of almost every other part of our coasts, — from the Channel Isles to the Shetlands, For these last I am indebted to the kindness of many zealous scientific friends, whose names appear in this volume, and to whom I here express my grateful obligation ; especially distin- guishing Mr. F. H. West of Leeds, and the Eev. W. Gregor of Macduff, as pre-eminent in their contributions. The result is that seventy-five species 'find their places in these pages, five of which are merely indicated, leaving seventy good species, exclusive of the LtLcemariadoe. Of these twenty- PREFACE. Vll four only are described in Johnston, — the rest of his species being either synonyms or resting on insufficient evidence. Fifty -four British species have been examined by myself, perhaps a larger number than have come under the notice of any other natiiraHst ; by far the greater part in life and health ; and thirty-four of these have been added to the British Fauna by mysel£ A new featiire in works of this sort, which will strike the student, perhaps needs a word of explanation ; — I mean the dis- tinguishing of the prominent varieties of each species by a diagnosis, and the assigning of a trivial name to each. Consider- ing the variability of many of the forms, I trust the convenience of this procedure will excuse the innovation. The analytical tables of the families, genera, and species, hitherto scarcely known in English zoological works, will, I think, be found useful ; nor wiU the attempt to tabulate the geographical distribution of the species be devoid of interest to the philosophic student. The plates must speak for themselves : they have been printed in colours by Mr. W. Dickes, who has spared no effort to make them, as nearly as possible, fac-similes of my original drawings, which were made from the Ufe. Nearly two years have been occupied in the progressive publi- cation of the work, as it has been issued in bi-monthly parts. Advantages and disadvantages attend this mode of publication. Among the former may be reckoned that the information is brought down to the latest period, and that the successive parts stimulate the zeal and co-operation of feUow-labourers ; the book thus embodying the knowledge of many, rather than of one. Among disadvantages must be put down, incongruities between the earlier and the later portions, statements made and opinions hazarded which are subsequently corrected, and omissions which are finally supplied. For these defects the author must cast himself on the kind consideration of his readers, who must be aware that no branch of science is at one stay even for a single month. Till PREFACE. My labour tas been performed con amove; I have looked forward to it for many years past; and it is with no small grati- fication that I see it completed. I send forth the result as one more tribute humbly offered to the glory of the Triune God, " who is wonderful in counsel, and excellent in working." P. H. GossB. ToBQUAT, December, 1859.

Though the following " History of the British Sea- anemones and Corals " is intended for general readers, it seems desirable that it should be accompanied by a brief rSsume of what is known concerning the anatomy and physiology of this order of animals. I have commenced the text of the work with a general description of the con- stituent parts of their bodies, in order to establish a determinate orismology for the class, and shall here assume that the reader is sufficiently familiar with the various organs, and the terms by which they are indicated. The Sea-anemones present a low grade of animal existence, and are commonly represented as exceedingly simple in structure. The term " Animal-flowers," by which they were known to the early observers, and which has been perpetuated in the Greek equivalent " Anthozoa," applied to the class by some modem naturalists, has been thought to express the fact, that a vegetable type of organization is scarcely less proper to them than an animal one. It is, however, to the accidental resemblance which these beautiful forms often bear to a highly-coloured and many-petal^d flower, that the name owes its appropriate- ness, rather than to any close assimilation to the vegetable structure. The Sea-anemone is an indubitable animal, and its organization is more complex than is usually supposed. This will be seen as we proceed with the successive ex- amination of the organs.* * In all cases in which I do not adduce any other authority, the following statements may be considered af» given on the authority of my own dissec- tions and observations. XU INTRODUCTION. 1. Tegumentary System. The skin is sufficiently distinct. After a few hours' maceration in fresh water {Sag. helUs), the epithelial and pigmental cells are easily removed with a hair-pencil, leaving the outer layer of muscular fibre bare. If the specimen be immersed in spirit for a day or two {A. dtanthus), the integument may be separated in flakes, which, under the microscope, are seen to be composed of a multitude of short corrugated fibrillee, set in no definite direction, interspersed with clear granules, pigment grains, and cnidae. An examination of the living animal {dtanthus, hellis, crassicornis, Hale. chrysantheUum, Cor. viridis, &c.) shows that the skin is composed of three elements, though these cannot always be separated. A layer of epithelial ciliated cells forms the first tunic : these are constantly in process of being thrown ofi" from the true skin, in the form of mucus ; but in some cases {Phellia, Edwardsia) they entangle foreign matters, and retain their cohesion as an investment more or less dense, and more or less firmly adherent to the skin. Below this is the true skin, of a more granular character, and carrying, imbedded in its thickness, a multitude of cnidae, whose discharging points are directed outwards. Intimately connected with this layer, but still lying sufficiently beneath it to be regarded as a distinct stratum, are the pigment-cells, which impart the colours to the animal. The tentacles of Aiptasia and Anthea (less conspicuously also of S. belh's) are lined with a dense layer of cells, forming to the naked eye a dark brown lining. Some peculiarities of these cells I have detailed (at page 187, infra) : it is probable that this layer may have some special function yet unrecognised. 2. Muscular System. In most species the muscular frame- work of the body is beautifully distinct, and the tissue is readily isolable. The column is a cylinder of muscular tissue, consisting of two layers, the outer composed of transverse, the inner of longitudinal, fibres. The trans- verse fibres are the more strongly marked : they average about "0001 inch in diameter, and are never striate. The cylinder which forms the column, is closed in most species by two extremities, which are flat, like the top and bottom of a tin canister : the former is the disk, the latter the base. Each of these is but a continuation of the same INTRODUCTION. Xin two layers of fibre that compose the columu-wall, — the outer transverse fibres becoming concentrically circular; the inner longitudinal ones converging to, or towards, a centre. In general, the boundaries of these divisions are distinctly marked by an abrupt angular change of the direction of the inner fibres ; but in some species (Ilyan- THiD^, Turhinolia, &c.), the body tapers gradually to a point below, without any angular change of direction. The fibres of the inner layer meet at a central point in the base, except in those species which have a central foramen there ; but in the disk they sustain another change of direc- tion, bending abruptly down at right angles, so as to form an inclosure in the axis of the column, parallel to the outer wall — the fibres of the outer layer still coating them. This downward prolongation forms the stomach, which will be presently described. In T. crassicomis the angle which is formed by the in- bending of the fibres to form the disk, is strengthened by a muscular cord, about half a line in thickness, consisting of annular fibres, and evidently acting as a sphincter : it is this band that forms the parapet. In Sagartia {Jbellis, miniata, nivea, &a) the muscular tunic, in contraction, corrugates into a reticulate or honey- comb-like pattern, inclosing shallow cells of much regu- larity. It is, I think, these inclosed areas, any one of which may be considered as a cell, with perpendicular walls of muscular tissue, that constitute the sucking warts, by means of which minute fi*agments of shell or gravel are grasped, and retained with considerable force. If this exposition is correct, all of the corrugated cells are capable of becoming suckers at the will of the animal ; but, in fact, only a few are so used at a time. The cells {nivea, miniata) are about 014 inch in depth and longitudinal diameter, while their transverse diameter may average about '084 inch. It is the outer layer of muscles that constitutes these corrugations. The sucking warts in the Bunodidce, are of similar character ; but here the elevation of the muscular tunic is more permanent, and the walls of the individual cells are thicker, and are incurved towards each other. To the muscular system belong the Septa. These are thin plates of muscular tissue, comprising the two layers of transverse and longitudinal fibres, doubled on each other, XIV INTRODUCTION. and stretching vertically through the cavity inclosed by the column. Each principal septum (Plate XI. fig. 1, a), in any of the normal species, is inserted, by its outer edge, into the column-wall throughout its entire height ; by its lower edge, into the base^ from the wall to the centre ; by its upper edge, into the disk, from the margin to the mouth ; and, by its inner edge, into the stomach, from the lip, almost to the free bottom of that viscus. From thence the inner edge recedes with an arching outline, and is free, until it is gradually merged in the lower edge at the centre of the base. Between these primary septa, others are developed in succession, partitioning off the imperfect chambers thus formed. But the septa of each successive cycle, while still inserted in the column-wall throughout, spring fi-om the stomach at higher and higher points, and terminate at points more and more remote from the centre of the base. The number of septa depends, to a certain limit, on the age of the individual, but in Peachia it never exceeds twelve, and in Halcampa microps, eight. In Peachia, the tissue of the septa is very dense, and still more so in T. crassicornis, where it assumes a firmness almost cartilaginous, and a decided blue colour. The muscular tissue of the disk protrudes in the form of hollow cones, which are the tentacles : each of these springs from an interseptal chamber, and hence their deve- lopment is in cycles corresponding to that of the septa. The fibres which compose their walls are very delicate. 3. Nervous and Sensory System. I have been as unsuc- cessful as my predecessors, in my search for nervous threads or ganglia; still, I have little doubt that such exist. I should expect their presence in the form of a ring, sur- rounding the mouth, perhaps with a pair of ganglia at the foaidial tubercles, distributing threads to the tentacles, have never observed any trace of auditory vesicles or otolithes, nor any organs that I could regard as eyes ; not even in the rudimentary form of those aggregations of pig- ment-cells, that occur on the margin of the Naked-eyed Medusae. A delicate sense of touch certainly exists, dis- tributed over the entire surface, but specially localized in the lips and the tentacles. The occasional elongation of one or more of these latter organs, and their employment (as described at pp. 34 — 36, infra) , indicate the existence of an active tactile faculty, and not merely of passive INTRODUCTION. XV irritability. The tips of the tentacles are bristled with the minute points, called by Dr. T. S. Wright palpocils* which he considers as delicate tactile organs. These are specially conspicuous on the globose heads of the tentacles of Corynactis and Caryophyllia. I am not sure whether I ought to regard, as an organ of taste, the surface of the lower part of the stomach, which in T. crassicornis I find covered with innumerable papillae, not quite uniform in size or shape, some being more pointed, others more round, and averaging about 0003 inch in diameter. 4. Digestive System. This is very simple, consisting essentially of a short tube descending from the centre of the disk, with an open extremity hanging loose in the body-cavity (Plate XI. fig. 1, c). I have already observed that the inner edges of the septa are inserted into its outer wall, and these maintain it in place, while by their trans- verse contraction they can draw asunder its surfaces, and by their longitudinal contraction they can either lengthen or shorten it. The stomach-wall itself, however, is muscular ; possessing at least the layer of transverse fibres, though I have not quite satisfied myself of the presence of the longi- tudinal layer. The form of the stomach is not that of a cylinder, but of a flattened sac, or of a pillow-case unsewed at both ends. This form may be well seen in pellucid specimens of A. diunthus, and in the smaller Ilyanthid^, and it may be examined by dissection in others. The excessive contrac- tion of the parts, and the copious excretion of mucus, do, however, present great obstacles to satisfactory demonstra- tions under the scalpel. I have therefore resorted to accessory means. A specimen of T. crassicornis folly expanded I treated with laudanum, drop by drop. It immediately expelled the water contained in the tentacles, causing these organs to shrink and shrivel, but not re- tracting them. The mouth, which had been pursed together, began slowly to open, and dilated greatly, almost to the concealment of the tentacles, the summit of the now flattened animal being almost wholly occupied by the gaping orifice. An excellent opportunity was thus afforded for examining the structure of the stomach, which was revealed without the excretion of mucus. The languor, too, induced by the narcotic, allowed the parts to be freely * See Edin. New Phil. Joum., April, 1857. XVI INTRODUCTION. touched with instruments without much effort at con- traction. The gular tube is remarkably corrugated longitudinally, the folds being so full, that a transverse section would present a series of figures 8. In the present state of con- traction there were horizontal corrugations also. At a short distance below the mouth the stomach ends abruptly, the edge, thin and delicate, hanging freely like a much folded curtain into the cavity. At each angle of this flattened sac the gonidial groove was conspicuous from top to bottom, inclosed by two slender columns of the firm cartilage-like muscle. The diameter of the digestive tube is, when at rest, not greater than that of the mouth ; indeed, the walls are in contact; nor, so far as my observation extends, are they ever separated except for the reception of food. It has been customary to represent the stomach as a sac pierced at the bottom " by one or more valvular openings which communicate with the cavity of the body."* But the case is as I have stated it : the free folded membrane hangs perpendicularly ; nor is there any thickening of the edge, nor any structure which at all resembles a sphincter. In tall specimens, I have observed, through the semi- transparent integuments, food pass into the stomach, and have marked that the morsel is invariably retained, never passing through to the general cavity ; but I am persuaded that this is effected by the common contractility of the walls, and not by a sphincter. When morsels of food, such as fragments of butchers' meat, are swallowed by Anemones, they are retained for some hours, and then vomited ; and because little change has passed upon the solid parts it has been rashly concluded that no process of digestion takes place in these animals. On this foolish hypothesis it is difficult to see why food should be swallowed at all, or what need the animal has of mouth or stomach. Their ordinary food, however, is not mammalian muscle, but the far softer and more fluid flesh of Crustaceay Mollusca, and Annelida. Nothing is more common than to find large specimens of A. mesemhryan- themum or T. crassicornis discharge, soon after their capture, » Siebold's Comp. Anat. § 37. " The stomach with its circular aperture at the oase " (Teale). Johnston, indeed, denies it any aperture at all : — " There is no — other visible exit from the stomach than the mouth." INTRODUCTION. XVU the shell of a crab, or a limpet, from which the entire flesh has been removed and replaced by a tenacious glaire. No doubt the first part of the process consists largely of ma- ceration, and continued pressure, by means of which the juices of the food are extracted. The nutritive matters thus obtained are then subjected to the action of the bile. No anatomist, I believe, has as yet attributed a liver to these animals, but I have little doubt that such is the character of a structure which I am about to describe. In dianthiis, crassicomis, Peachia undata, and others, the stomach- wall is lined on the interior side of its upper portion (the side, I mean, which is within the interseptal chambers) with a thick highly -coloured sub- stance. In the first two named this is yellow or orange, in the last salmon-red. This lining is {dianthus) about half a line in thickness, of a pulpy tissue, arranged in irregular lobules, covered with a ciliated epithelium (^Plate XI. fig. \, d). On being crushed down, the pulp is found to be composed of a nearly uniform mass of yellow fat-cells, the largest of which are about '0003 inch in diameter, and the smallest immeasurable points. Cnidae occur numerously in the true stomach-wall, but none in this lining-coat. I am justified, then, in presuming this organ, from its colour, form, position, and structure, to be a liverJ^ In Aiptasia I find what I think an analogous structure, but with a slightly varied position. The septa, instead of being inserted into the stomach-wall from the point where they spring ofi" to the summit, recede from it at their upper part, where their edges carry rounded pulpy lobes, which under pressure consist of a clear tenacious sarcode, carrying a moderate number of brown pigment-cells. The sarcode is composed of globose cells, averaging "0005 inch in diameter, each containing more or fewer oil-globules, * As an example of the need of caution in such observations as these, I may be pardoned for mentioning the following circumstance : — WhUe viewing the surface of the pulpy tissue above described under a good reflected light with a power of 133 diameters, I saw it forming irregular lobes, with deep narrow sinuous depressions. Over the surface, and chiefly following the lines of the sinuosities, I noticed meandering white lines, like very slender branching threads. The thought that I had dis- covered veritable nerves immediately occurred to me ; but turning the mirror of the microscope to test the observation with a different angle of the light, I found I had been looking at merely the light reflected frvm the edge of the smooth lobules I h XVlll INTRODUCTION. averaging "0005 inch, but some attaining '0003. These are very numerous in the mass. 5. Circulatory and Eespiratory systems. These exist in so simple a condition that we can scarcely separate them in our investigations. Dr. Williams has distinguished by the term Chylaqueous fluid, " that fluid which occupies the gastric and perigastric cavities of all animals below the Annelida."* It is far less vitalized than true blood, but still it is not mere water, being impregnated with organized corpuscles and slightly albuminized. In the animals of the class before us there is no blood, and no vascular system, but the cavity of the body is ample, and is copiously occupied by a transparent fluid, which has by some been mistaken for sea-water. I have, however, proved by ex- periments, recorded elsewhere,! on numerous species, that this fluid is copiously provided with organic corpuscles, circular or ovate disks, granulose in character, of a clear yellow colom*, varying from '0001 to -0008 inch in diameter, the larger ones inclosing oil-globules. The fluid coagulates on the addition of ilitric acid, showing that it holds albu- men in solution. It would appear that the action of the stomach is confined to the solution and extraction of albumen and oil, which are carried with sea-water into the general cavity, the com- pound being a chylaqueous fluid ; and that it is in the upper part of the interseptal chambers that it is acted upon by the biliary secretion. For the free circulation of this fluid to every part of the interior, the whole body is lined with a delicate, strongly ciliated epithelium. The ciliary current is upward : when a pellucid dianthus has its fosse much exposed, it is quite easy to see the current driving up from every part of the interior along the whole inner wall, and passing into the tentacles, up which the atoms are then hurled. I believe there is no change in the set of this current : for though atoms are seen, especially at the bottom of the tentacles, occasionally to pass annularly or diagonally; and though of course there must be a return of the fluid driven up- ward — for there does not appear, with the closest watching, a trace of exit at the tip of the tentacles; and though, indeed, atoms are seen, though rarely, to pass downward, — I think these irregular and retrogTade movements are • Phil. Trans. 1862. f Annals of Nat. Hist.; March, 1858. INTRODUCTION. XIX merely the mechanical result of the impact of the ciliary current on the closed tip. If so, the current runs upward on the whole inner surface of the walls, and then returns down the centre. And this, I am persuaded, is the case. That the tentacles are perforated at the tip is, however, certain : but it is closed or opened at the will of the animal, the outer annular layer of fibres acting as a sphincter. Nothing is more common than to see a fully expanded indi- vidual of T. crassicornis, when suddenly alarmed, eject slender streams of water from the tips of its tentacles ; and I have seen an instance in which, the animal being but just covered with water, the jets were projected to a height of three inches above the sm"face. In S. helUs, after macera- tion, the slightest pressure on these organs causes the pigment to ooze out at the tip. In many that I so treated, not one allowed it to escape at the side ; nor in any case was there the least appearance of resistance, suddenly yielding as if by a rupture ; nor did the aperture in any case enlarge, nor was it in any case otherwise than at the precise extremity. From which circumstances I infer a natural foramen there ; and think that it exists in all species, except those (as Corynactis and Caryophyllia) which have a globose appendage at the extremity of the tentacle. The circulation of the nutrient fluid is aided by a curious apparatus of foramina, of which I have met with no description. It is diflficult to find them in dissection, for they appear to close with contraction ; but in hellis, on making a transverse section just below the disk, I have found a small round aperture in each primary and secon- dary septum, through which I could thrust a probe without laceration. It is during life, however, that, under certain favourable circumstances (for they cannot at all times be detected), they must be studied. In dianthiis, when very much distended, I have seen the principal septa perforated with a large circular foramen in the midst of their broadest part, resembling iron girders supporting a floor, excavated for lightness (Plate XI. fig. l,b). In Anthea cereus they are conspicuous;* but I have been unable to detect them in T. crassicornis or in CoryncLCtis. * The most satisfactory observations I have made on these perforations were on a specimen of Anthea cereus, var. sulphurea. Being very much expanded, and distended to translucency, the base adherent to the side of a glass tank, the column greatly exceeding the base, the -window opposite, h 2 XX INTRODUCTION. That the function of Respiration should be widely dif- fused and very simple in these animals will follow from what has been said. The ehylaqueous fluid, consisting largely of sea-water admitted freely from without, is itself a reservoir of oxygen, and thus its organized elements are perpetually aerated. We have already seen how the ciliary currents within maintain a constant succession of the bathing fluid upon every part ; and there can be no doubt that some mode of exit is provided for the effete water. What this is, however, I know not. In Cerianthus, which has a posterior foramen to the body-cavity, I have seen the water forcibly ejected from this aperture (see infra, p. 272) ; I have also marked a sudden jet d'eau from the disk (pro- bably from the mouth, but of this I was not sure) ^ of T. crassicorm's, which shot up some mucous shreds with force to the surface, a height of some five inches. Perhaps these expulsions, and those from the tentacle-tips already alluded to, may be set doAvn as so many expirations (per- haps periodical) of deoxygenated water. Ancillary to respiration, as renewing the water in the vicinity of the animal, is the ciliation of the external sur- face. This is strong and uniform on the tentacles, but I have never been able satisfactorily to trace it on the column. It is first visible at the margin, flowing in an even current up the tentacle, on every side, from the foot to the I saw with a lens, for an hour together, with the utmost distinctness, a small circular (oval in perspective) foramen in each septum. That is, I saw them in a dozen or more successive septa, without interruption. The diameter of the foramen was about the same as that of a tentacle near the tip, in its ordinary state of extension. That the foramina were in films whose surfaces were coincident with the line of vision, and not transverse to it, I proved, by moving my eye to the i-ight and left, by which the foramen became more and more round, or more and more linear, the line in the latter case being that of the axis of the column. Hence they must have been in films running from the column-wall towards the axis perpen- dicvilarly, as regards the position of the animal; — conditions which agree with the septa, and with them only. The next day, with a very favourable sight, I traced the foramina conse- cutively for half the circumference of the animal. In this space there were 49 septa (perhaj^s one more than the half, for I bisected only with mj- eye) ; and I found that the foramina are pierced through those which are entire (by far the greater ntimber), but that the series is interrupted irre- gularly by those imperfect septa, which span the cavity like an arch The latter were invariably two together, differing much in the height of the arch, and graedum, and their emitting extremities either close to its edge, or projecting from it. The more dense their aggrega- tion, the more definitely is this arrangement maintained; doubtless because displacement of their original position is more readily effected by the flattening action of the com- pressorium, when the cnideB are more loosely scattered in the fluid sarcode. The peritoneal membrane which invests the whole is richly ciliated on its entire surface. (Plate XI. fig. 3.) The Acontia. Certain species of the Zoophytes under consideration have the faculty of shooting forth from the mouth, as well as from minute orifices scattered over the surface of the body, slender flexible filaments, usually of an opaque white hue, but sometimes, as in Adamsia palliata, of a brilliant lilac tint. In some instances, as in Sagartia parasitica, S. mi^iiafa and Adamsia palliata, these threads are protruded in great profusion, coiled up in irregular spirals, and forming tangled masses that resemble bundles of sewing cotton. It appears to be a means of defence ; and any of the species just mentioned may readily be excited to display these weapons by a slight irritation of the surface of the body. The slightest touch is usually a sufficient stimulus to the extension, which will often continue to proceed for some time, the filaments shooting forth from various points with great force and rapidity. They have a strongly adhesive power, which, however, is not dependent on any superficial viscosity, but on the projectile power of the contained oiidce, of which I shall presently speak. If we carefully watch one of these threads, we shall perceive that after a time it is gradually withdrawn again into the body, by the orifice at which it was protruded. In the case of 8. parasitica, a large species, these filaments, which I designate by the term acontia, sometimes extend six inches from the body, in a straight line. Yet in a few minutes the whole has disappeared. It is gradually cor- rugated into small irregular coils, at the end which is attached to the animal ; and these little coils are, one after INTRODUCTION. XXV another, sucked in, as it were, through an imperceptible orifice. Acontia are less universal than craspeda, for whereas the latter are always present, so far as I know, in this order, the former are found onlj in the Sagartiad(£, and perhaps in the BunodidcR. In Sagartia hellis thej spring from the mesenteries that carry the craspeda; generally two acontia from each mesentery, and most frequently in pairs. Their point of insertion may be anywhere in the length of the mesentery, great irregularity prevailing in this respect. Though at first it seems a solid cylinder, the acontium is really a flat narrow ribbon, with involute and approximate edges, which can at pleasure be brought into contact, and thus constitute a tube (Plate XI. fig. 4). Like the craspeduin, of which it seems to be a form modified for a special use, its surface is richly ciliated ; and the ciliary currents not only hurl along whatever floating atoms chance to approach the surface, but cause the detached fragments themselves to wheel round and round, and to swim away through the water. Though there is not the slightest trace of fibrillge in the structure of the acontium, even under a power of 800 diameters, the clear sarcode, of which its basis is composed, is endowed with a very evident contractility. Under pressure, the edges of the flattened acontium appear to be thronged with clear viscous globules, over- lapping one another, and protruding ; indicating one or more layers of superficial cells, doubtless forming the peritoneal epithelium. As the pressm-e is increased, these ooze out as long pear-shaped drops, and immediately assume a perfectly globular form, with a high refractive power. Below these is packed a dense crowd of cnidce, arranged transversely. The Cinclides. The emission of the acontia is provided for by the existence of special orifices, which I term Cinclides. The integument of the body, in the Sagartia, is perforated by minute foramina, having a resemblance in appearance to the spiracida of insects. They occur in the interseptal spaces, opening a communication between these and the external water. The appearance of the cinclides may be compared to that which would be presented by the lids of the human XXVI INTEODUCTION. eye, supposing these to be reversed ; the convexity being inwards. Each is an oval depression, with a transverse slit across the middle. When closed^ this slit may some- times be discerned merely as a dark line (Plate XI. fig. 5, m], the optical expression of the contact of the two edges ; but, when slightly opened {T), a brilliant line of light allows the passage of the rays from the lamp to the beholder. From this condition the lids may separate in various degrees, until they are retracted to the margin of the oval pit, and the whole orifice is open (Jc). The dimensions of the cinclides vary not only with the species, and probably also with the size of the individual, but with the state of the muscular contraction of the integu- ments, and, as I think, with the pleasure of the animal. In a small specimen of S. dianthus, I found the width of a cinch's, measured transversely, ^th of an inch ; but that of another, in the same animal, was more than twice as great, viz. jsnth of an inch. This was on the thickened marginal ring, or parapet, which in this species surrounds the tentacles, where the cinclides are larger than elsewhere. Watching a specimen of S. nivea under the microscope, I saw a cinclis begin to open, and gradually expand till it was almost circular in outline, and a^sth of an inch in diameter. I slightly touched the animal, and it in an instant enlarged the aperture to 2^th of an inch. In a specimen of S. hellis, less than half grown, I found the cinclides numerous, and sufficiently easy of detection, but rather less defined than in dianthus or nivea. They occurred at about every fourth intersept, three intersepts being blind for each perforate one, and about three or four in linear series, but not quite regularly, in either of these respects. In this case they were about eVth of an incli in transverse diameter, a large size, — and I measured one which was even g^th of an inch. By bringing the animal before the window, I could discern the light through the tiny orifices with my naked eye. From several good observations, and especially from one on a cinclis, widely opened, that happened to be close to the edge of the parapet of a dianthus, I perceived that the passage is not absolutely open, at least in ordinary, but that an excessively thin film lies across it. By delicate focusing, I have detected repeatedly, in different degrees of expansion, and even at the widest, the granulations of a INTBODUCTION. XXVll membrane of excessive tenuity, and one or two scattered cnida, across the bright interval. On another occasion, in the case of a cinch's at the edge of the parapet — a position singularly favourable for observation — I sa"w- that this subtle film was gradually pushed out until it assumed the form of a hemispherical bladder, in which state it remained as long as I looked at it. At the same time the outline of the cinch's itself was sharp and clear, when brought into focus farther in. The film, whatever it be, is superficial, and does not appear to be a portion of the integument S roper. I take it to be a film of mucus (composed of eorganized epithelial cells), which is constantly in process of being sloughed from all the superficial tissues in this tribe of animals, and which continues tenaciously to invest their bodies, until, corrugated by the successive contractions of the animals, it is washed away by the motions of the waves. As, however, one film is no sooner removed than another commences to form, one would always expect external pores so minute as these to be veiled by a mucus- film in seasons of rest. That the cinch'des are the special orifices through which those missile weapons, the acontta, are shot and recovered, rests not merely on the probability that arises firom the coexistence of the two series of facts I have above recorded, but upon actual observajtion. In a rather large S. diantkus, somewhat distended, placed in a glass vessel between my eye and the sun, I saw, with great dis- tinctness, by the aid of a pocket-lens, many acoiitia protruded from the cinch'des, and many more of the latter widely open. The acontta, in some cases, did not so accurately fill the orifice but that a line of bright light (or of darkness, according as the sun was exactly opposite or not) was seen, partially bordering the issue of the thread, while the thickened rim of the cinch's surrounded all. The appearance of the orifices whence the acontta issued was that of a tubercle or wart, and the same appear- ance I have repeatedly marked in examples observed on the stage of the microscope ; namely, that of a perforate pimple, or short columnar tube. Tliis was clearly manifest, when the animal, slowly swaying to and fro, brought the sides of the cinch's into partial perspective. On another occasion I witnessed the actual issue of the acontia from the cinch'des. I was watching, under a low XXVin INTRODUCTION. power of the microscope, a specimen of >S'. nivea, while, by touching its body rudely, I provoked it to emit its missile filaments. Presently they burst out with force, not all at once, but some here and there, then more, and yet more, on the repeated contractions of the corrugating walls of the body. Occasionally the free extremity of a filament would appear, but more frequently the hight of a lent one, and very often I saw two, and even three, issue from the same cinclis. The successive contractions of the animal under irritation, caused the acontia already protruded to lengthen with each fresh impetus, the bights still streaming out in long loops, till perhaps the free end would be liberated, and it would be a loop no longer ; and sometimes a new thread would shoot from a cmclis, whence one or two long ones were stretching already ; while, as often, the new- comers would force open new cincUdes for themselves. The suddenness and explosive force with which they burst out, appeared to indicate a resistance which was at length overcome : — perhaps — in part at least — due to the epithelial film above mentioned, or to an actual epiderm, which, though often ruptured, has ever, with the aptitude to heal common to these lowly structures, the power of quickly uniting again. It appeared to me manifest, from this and other similar observations, that no such arrangement exists as that which I had fancied ; — that a definite cinclis is assigned to a definite acontium, or pair of acontia, and that the extremity of the latter is guided to the former, with unerring accu- racy, by some internal mechanism, whenever the exercise of the defensive faculty is desired. What I judge to be the true state of the case is as follows : The acontia, fastened by one end to the septa or their mesenteries, lie, while at rest, irregularly coiled up along the narrow interseptal fossae. The outer walls of these fossae are pierced with the cinclides. When the animal is irritated, it immediately contracts ; the water contained in the visceral cavity finds vent at these natural orifices, and the forcible currents carry with them the acontia, each through that cinclis which happens to lie nearest to it. The frequency with which a loop is forced out shows that the issue is the result of a merely mechanical action; which is, however, not the less worthy of our admiration because of the simplicity of the contrivance, nor the less manifestly the result of Divine INTRODUCTION. XXIX wisdom working to a given end "bj perfectly adequate means. The ejected acontia, loaded with their deadly cnidffi in every part of their length, carry abroad their fatal powers not the less surely, than if each had been provided with a proper tube leading from its free extremity to the nearest cinch's. The Cnidce. — I come now to describe those minute but potent organs which constitute the object of all the mecha- nism above described. Four distinct forms of these cap- sules have occurred to my investigations ; and these I shall treat of in turn. (1.) Chambered Cnid(B {Cnid(B cameratcB). This is perhaps the most generally distributed fonu, as it is manifestly the most elaborately armed. It may be well examined in CaryophylUa SmitTiii. The globular heads of the tentacles seem, under pressure, to be literally com- posed of these capsules, the ends of which project side by side, as close as they can be packed, one against another. The form of these is long and slender, almost linear. The craspeda are also similarly studded with cnidee, which are, however, of longer dimensions, and of fuller form. As I have seen no chambered cnidae, in any species, so large as these, I shall take them as a standard for description, alluding to those of other species only when they differ from these. They are perfectly transparent, colom-less vesicles, of a lengthened ovate figure, considerably larger at one end than at the other (Plate XI. fig. 6). One of average dimensions measures in length "004 inch, and in greatest diameter '0005. In the larger (the anterior) moiety, is seen, passing longitudinally through its centre, a slender chamber, fusiform or lozenge-form, about '00015 inch in its greatest transverse diameter, and tapering to a point at each extremity. The anterior point merges into the walls of the cn{d(B at its extremity, while the posterior end, after having become attenuated like the anterior, dilates with a fonnel-shaped mouth, in which the eye can clearly see a double-infolding of the chamber-wall. After this double fold the structure proceeds as a very slender cord, which, passing back towards the anterior end of the capsule, winds loosely round and round the chamber, with some regularity at first, but becoming involved in contortions more and more intricate as it fills up the posterior moiety of the cavity. The fusiform chamber appears to be marked on XXX INTRODUCTION. Its inner surface with regularly recurring serrations, which are the optical expression of that peculiar armature to be described presently. Under the stimulus of pressure, when subjected to micro- scopical examination, and doubtless under nervous stimulus, subject to the control of the will, during the natural exer- cise of the animal's functions, the cnid(B suddenly emit their contents with great force, in a regular and prescribed manner. It must not be supposed, however, that the pres- sure spoken of is the immediate mechanical cause of the emission : the contact of the glass-plates of the compres- sorium is never so absolute as to exert the least direct force upon the walls of the capsule itself; but the disturbance produced by the compression of the surrounding tissues excites an irritability which evidently resides in a very high degree in the interior of the cnidee ; and the pro- jection of the contents is the result of a vital force. In general the eye can scarcely, or not at all, follow the lightning-like rapidity with which the chamber and its twining thread are shot forth from the larger end of the cnida. But sometimes impediments delay the emission, or allow it to proceed only in a fitful manner, a minute portion at a time ; and sometimes, from the resistance of friction (as against the glass-plate of the compressorium), the elongation of the thread proceeds evenly, but so slowly as to be watched with the utmost ease ; and sometimes the process, which has reached a certain point normally, be- ' comes, from some cause, arrested, and the contents of the cell remain permanently fixed in a transition state. Thus a long continued course of patient observation is pretty sure to present some fortuitous combinations, and abnormal conditions, which greatly elucidate phenomena that nor- mally seemed to defy investigation. In watching any particular cnida, the moment of its emission may be predicted with tolerable accuracy by the protrusion of a nipple -shaped wart from the anterior extremity. This is the base of the thread. The process of its protrusion is often slow and gradual, until it has attained a length about equal to twice its own diameter, when it suddenly yields, and the contents of the cnida dart forth. At this instant I have, in many instances, heard a distinct crack or crepitation, in the examination of cnidce both of this species and of S, parasitica. INTRODUCTION. XXXI When fuUj expelled, the thread or wire, which I distin- guish by the term ecthoroium (Plate XI. tig. 7, n), is often twenty, thirty, or even forty times the length of the cnida ; though, in some species, as in most of the Sa^artice, it frequently will not exceed one-and-a-half, or two times the length of the cnida. The ecthoraa, which are discharged by chambered cnidce, are invariably furnished with a peculiar armature. The basal portion, for a length equal to that of the cnida, or a little more, is distinctly swollen, but at the point indicated it becomes (often abruptly) attenuated, and runs on for the remainder of its length as an excessively slender wire of equal diameter throughout. In the short ecthorcea of Sagartia, the attenuated portion is obsolete. It is chiefly upon this ventricose basal portion that the elaborate armature is seen, which is so characteristic of these remarkable organs. For around its exterior wind one or more spiral thickened bands, varying in different species as to their number, the number of volutions made by each, and the angle which the spiral forms with the axis of the ecthorceum. The whole spiral, formed of these thickened bands, I designate the screw, or strehla (fig. 7, o). In the ecthorcea emitted by chambered cnidce from the craspeda of T. crassicornis, the screw is formed of a single band, having an inclination of 45° to the axis, and be- coming invisible when it has made seven volutions. In those from the same organ in S. parasitica we find a screw of two equidistant bands, each of which makes about six turns, — twelve in all, — having an inclination of 70° from the common axis. In those similarly placed in Caryojjhyllia, the strehla is composed of three equidistant bands, each of which makes about ten volutions — thirty in all — with an inclination of about 40° from the axis. In every case the spiral runs from the east towards the north, supposing the axis to point perpendicularly upwards. Sometimes, especially after having been expelled for some time, the wall of the ecthorceum becomes so attenu- ated as to be evanescent, while the strehla is still distinctly visible. An inexperienced observer would be liable, under such circumstances, to suppose that the screw, when formed of a single band, as in T. crassicornis, is itself the wire ; an error into which I myself had formerly fallen. An XXXll INTRODUCTION. error of another kind I fell into, in supposing that the triple screw of the wire in C. Smitkii was a series of imbricate plates : the structure of the armature is the same in all cases (with the variations in detail that I have just indicated) ; and the structure is, I am now well assured, a spiral thickened band, running round the wall of the ecthoreeum on its exterior surface. I have been able, when examining such large forms as those of Corynactis and Caryojphyllia, with a power of 750 diameters, to follow the course of the screw, as it alternately approached and receded from tlie eye, by altering the focus of the objective, so as to bring each part successively into the sphere of vision. These thickened spiral bands afford an insertion for a series of firm bristles, which appear to have a broad base and to taper to a point. Their length I cannot determin- ately indicate, but I have traced it to an extent which considerably exceeds the diameter of the ecthoraium. These barbed bristles I denominate ^>ferj/^^*«. (See fig. l,p.) The number of pterygia appears to vary within slight limits. As well as I have been able to make out, there are but eight in a single volution of the one-banded strebla in T. crass icornis ; while in the more complex screws of S. parasitica, Cor. viridis, and Gary, Smith ii there appear to be twelve in each volution. The barbs, when they first appear, invariably ^ro;ec< in a diagonal direction from the ecthoraum ; and sometimes they maintain this posture ; but more commonly, either in an instant, or slowly and gradually, they assume a reverted direction. From some delicate observations, made with a very good light, I have reason to conclude that the strebla, and even the pterygia, are continued on the attenuated portion of the ecthoreeum, perhaps throughout its length. In Corynactis and Caryophyllia I have succeeded in tracing them up a considerable distance. In the latter I saw the continuation of all these bands, with their bristles; but the angle of inclination had become nearly twice as acute as before, being only 22° from the axis. The appearance of tlie attenuate portion, as also of the base of the ventricose part, is exactly that of a three-sided wire, twisted on itself; the barbs projecting from the angles. (2.) Tangled Cnidce (Cnidce glomifera;). This form is very generally distributed, and is mingled with the former INTRODUCTION. XXXUl in the various tissues. In the genus Sagartia, however, it is by far the rarer form, while in Actinia and Anthea, it seems to be the only one. The pretty little Corynactis viridis is the best species that I am acquainted with for studying this kind of cnida. Their figure is near that of a perfect oval (Plate XI. fig. 9), but a little flattened in one aspect, about 004 inch in the longer, and 'OOlo in the shorter diameter. Their size, therefore, makes them peculiarly suitable for observations on the structure and functions of these curious organs. Within the cavity is a thread (ectJioraum) of great length and tenuity, coiled up in some instances with an approach to regularity, but much more commonly in loose contor- tions, like an end of thread rudely rolled into a bundle with the fingers. The armature of this kind does not differ essentially firom that already described. It is true, I have detected it only in Coryndctis, where the short ecthoraum of the tangled cnida is surrounded throughout its length by a barbed strebia of three bands. The barbs are visible under very favourable conditions for observation, even while the tangled wire remains enclosed in the cnida, but their optical expression is that of serratures of the walls, without the least appear- ance of a screw. This is the only species in which I have actually seen the armature of the ecthoreeum in this kind of cnida, but I infer its existence from analogy, in other species, where the conditions that can be recognised agree with those iu this, though the excessive attenuation of the parts precludes actual observation of the structure in question. (3.) Spiral OntdcB [Cnida cochleatce). In a few species, as S. parasitica, T. crassicornis, &nd Cerianthus Lloydii, I have found very elongated fusiform c«i'c/isk. Agrees with the column. Tentacles. Generally agree with the column, but in the oUve and brown varieties, they are sometimes almost wholly pellucid-white, and in all cases they are marked with a single transverse bar of white, near their middle ; most conspicuous in youth.

All rovmd the coasts of Europe, in deep water, and on dark rocks between tide-marks. Varieties. These might be made as nximerous as the various shades of colour above- mentioned ; but for practical purposes it may be sufficient to distinguish the following : — a. Brunnea. Including the shades of brown, from dingy blackish olive, to warm umber, or fawn-colour. Sometimes, as in examples that have fallen under my own observation, the tentacles, in these brown specimens, are almost white, marked with the more opaque white bar. There is not the sUghtest reason to assign these, as has been suggested, to another species. i8. Ruhida. The various tints of red, from the full minium-scarlet to the peach-blossom and flesh-colour, may be classed under this variety, which is perhaps the most abundant of all. y. Flava. Sir John Dalyell enumerates " lemon-yellow " among the hues of this species; but it must be a very rare variety. I have never seen it. 5. Sindonea. Perhaps this is the most elegant variety ; the animal being clad in translucent white — " simplex munditiis," as if arrayed in the finest Coan vestments. It is not vmcommon. This noblest of our native Sea-anemones seems to be entitled to generic separation from the Sagartice, with which I have hitherto associated it. Its form and habit, its puckered disk, its crowded and fringe-like tentacles, its thickened parapet and deep fosse, and the presence of only 14 SAGARTIAD^. a single mouth-groove, are well-marked characters peculiar to it among our British species. This last peculiarity- isolates the species from every other with which I am acquainted. The generic appellation Actinoloha, I have adopted from De Blainville, who formed the genus in his " Actinologie" (1834). It is sufficiently expressive; but objectionable on account of its construction. It is a good canon that no generic name ought to form a part of a second generic name. In this case the word is constructed out of Actinia, and \oj3ors, there are still variables ; and, moreover, no one form, typical though we consider it, can be a full expression of the species, so long as variables are as much an essential part of its idea as constants. The advantage of fixing upon some oiie variety as the typical form of a species is this, — that the mind may have an initial term for the laws embraced under the idea of the species, or an assumed centre of radiation for its variant series, so as more easily to comprehend those laws." — (Dana's " Thoughts on Species.^) 30 SAGARTIADiE. (. Stellata. Disk pale buflF; a broad darker circle at the commencemeut of the tentacular border. Tentacles long and pointed ; very pale stone- drab, each varied with pellucid patches, which give a pretty and deUcate effect. But what is most peculiar is the alternate depression and elevation of the margin, a kind of frilling, which imparts to the disk a star-like form, usually of seven rays. This is a large and well-marked variety. The genus Sagartia was established hy me in a Memoir* read before the Linnean Society, March 20th, 1855. I then included in it dianthus, as well as the species to which I now confine it. The character on which I mainly relied in constituting it, appears to me, on maturer consideration, to mark a group of higher value than that of a genus ; and I have accordingly used it to characterise a family. Hence it became necessary to make a fresh diagnosis of the genus, which, though large, appears a very natural one. The name I have chosen alludes to the peculiar mode of dis- abling their prey, by means of missile cords, which is possessed pre-eminently by the species of this group, re- calling to my mind a graphic passage in the writings of the Father of History. In the army of Xerxes, he says, — " there was a certain race called Sagartians. The mode of fighting practised by these men was this : — when they engaged an enemy, they threw out a rope with a noose at the end ; whatever any one caught, whether horse or man, he dragged towards himself, and those that were entangled in the coils were speedily put to death," f The specific appellation of the present subject is the botanic name of a favourite flower, — the modest Daisy ; — helUs, from bellus, 'pretty. Though the Daisy Anemone is, as I have shown, subject to considerable variety, and has no one very strongly * ■" Description of Peachia hastafa, &c." Linn. Trans, xxi. 267. t Herodotus, vii. 86. THE DAISY ANEMONE. 31 marked, and at the same time constant, specific character, there is scarcely any of our species more readily or more certainly recognisable. Its variations are circumscribed' within appreciable limits, both of colour and form, and it has little tendency to merge into the characteristic con- dition of any other (British) species. Indeed, but ^for the needless multiplication of genera, I should be tempted to separate it from the other Sagartice, constituting for it, in association with two or three closely allied forms from the southern hemisphere, a distinct genus. From the elegance of its form, and its ready power of accommodating itself to captivity, few of our native species are more favourite tenants of an aquarium than this. Its habits, too, render it easily accessible. Within the limited range of its habitat it is for the most part "abundant. The rugged, indented, rocky shores of Devon and Cornwall seem to be the metropolis of the species : and here the tide-pooLs, fissures, and honeycomb-like burrows of the SaxicavcB, are densely crowded with the pretty Daisy. The broad front of Capstone Hill, at Ilfracombe, is broken, within the range of the tides, into a succession of narrow horizontal shelves, the angles of which run down into long fissures. The limestone promontory, known as Petit Tor, on the south-east coast of Devon, presents many ledges very similar in character, but more eroded into irre- gular holes and cavities. In both of these localities, hellis abounds, generally of the beautiful scarlet-lined variety, Tyriensis. Each usually occupies a little hollow, being attached by its base to the bottom, and expanding its beautiful disk over the edge. In the broader basins, moreover, which the waves have worn, " hollows of the tide-worn ree^" overshadowed by ribbon-shaped sea-weeds, — which are the very counterparts, in the sea, of the hart's-tongue fern 32 SAGARTIADJE. fronds which overarch the green hedge-banks just above, — larger and finer specimens occur, apparently each broad coin-like disk stuck on to the smooth wall of the cavity, but really, as you find when you attempt to capture it, imbedded in its own proper cranny, into which it can retire out of danger. But it is as common to find colonies of the species, inhabiting the long narrow fissures, covered with but an inch or two of water when the tide is out ; five, ten, or even twenty individuals crowded together in a line as close as their bases, firmly planted side by side, will admit. Here, of course, when expanded, the puckered edges of each disk press upon and fit into the mutual irregularities of the others ; and the effect is very attractive, when the variety is that patched one, pale blue and black, which I have named versicolor. I have much admired them in this condition along the foot of the lofty overhanging cliffs at Watcombe, between Teignmouth and Torquay. Huge masses of the red con- glomerate have fallen from above, and are piled in con- fusion along the whole sea-line. And these seem to have formed a natural breakwater, protecting the base of the cliff from the action of the waves. Hence the lower part of the rock remains in situ, while all the upper and middle portions have been detached by the influence of rains and frosts, and have fallen ; and this lower part forms a suc- cession of sloping terraces, averaging perhaps some twenty feet above low-water mark. Each successive terrace dips to the northward at a very gentle angle with the horizon, so that the explorer has to mount from one to another in turn, while he pursues the line of coast, as each slope successively brings him to the water^s edge. These ter- races are very rough, but not unpleasant to walk iipon; and their angles are occupied with water, forming long THE DAISY ANEMONE. 33 narrow shallow pools, the bottoms of which run down into thin crevices. In these crevices reside the Daisies in question, in great numbers, and some of them of very large dimensions, as three inches in diameter, when follj ex- panded. They are, however, as I have said above, mostly so crowded together, that they are not able to spread their blossom-disks fully, but are fain to accommodate each other, by allowing the protrusions of one sinuous and frilled margin to fit into the recesses of another. They thus con- stitute lines of variegated frills, in which the individuals cannot be separated by the eye of the beholder ; and though no brilliant hues appear, there is sufficient contrast between the black and the white, the blue and the grey, all puckered and convoluted as the fringed outlines are, to gratify the eye. Nor are these very difficult of possession. For the con- glomerate, though hard, yields readily to the chisel, and the edges of the crevices present in many cases fair angles for the blows of the experienced collector. The Daisy is not unfrequently brought up in the dredge from a few fathoms' depth. In Weymouth Bay I have repeatedly obtained it thus, but still maintaining its wonted troglodyte habit ; for its favourite domicile is one of the deep angular chambers formed by the leafy expansions of that fine coral-like Polyzoan, Eschara foliacea. But Weymouth possesses a breed of the species which deviates much more widely from the normal habit. It is the variety which I have called sordida, having an eye not less to its filthy dwelling-place than to its dirty colour. The broad expanse of fetid mud, either wholly bare at low tide, or covered only with a foot or two of water, that floors the two inlets called the Fleet and the Backwater, is studded with multitudes of these dingy Anemones. The soft slimy mud affi)rds no proper surface for adhesion ; I 34 SAGARTIAD^ae. and hence the animals can scarcely be said to adhere in the manner of the family, but simply to rest on the broad base. This is not, however, indicative of any defect in the power of adhesion ; for on being removed to a basin of sea-water, they are soon found firmly attached to the bottom and sides. With these exceptions I have not found hellis at Wey- mouth ; which is the more remarkable since the long ledges of low rock, broken into fissures, and excavated into num- berless hollows, would seem to present a favourable site for it. But since my residence there, it has yielded, in con- siderable abundance, the beautiful variety stellata ; which, as I understand, occurs to the north-east of the town. In Dr. Johnston's Brit. Zooph. (p. 231) may be found some curious figures by Mr. Cocks, illustrative of the pro- tean mutability of shape manifested by this species. This depends on the power of distending the body generally with water, together with that of strongly constringing some part, the constriction ever moving its place. Several of the Sagartice (as S. helUs, miniata, and troglodytes) have a singular habit of elongating to an im- mense extent one of the tentacles, while all the rest remain in the ordinary condition. The phenomenon has once or twice fallen under my own observation, but I will describe it in the words of some of my kind correspondents, who have from time to time directed my attention to it. It seems to have been first noticed in S. troglodytes by Mr. Hugh Owen of Bristol, who, in May, 1856, mentioned the fact in a letter to me. Soon afterwards he observed the same phenomenon in " a loosely-formed hellis, with longer tentacula than usual, found in a cave at Tenby." " I was, a few days since," he writes, " watching it closely, when one tentacle began to extend itself; and for an hour I watched its motions. The animal is about an inch and a half in I THE DAISY ANEMONE. S5 extreme diameter, and it threw out its tentacle to a dis- tance of three inches from the margin. Of course all colour disappears, and it requires one to he looking for the fact to ohserve the transparent memhranous nature of the ex- tended limb. I tried if its object was seeking for food, by dropping a scrap of meat in the way of the tentacle : it was seized and carried to the oral disk instantly." The same gentleman in a subsequent letter (dated 7th July, 1856) thus continues his observations : — " Another specimen of bellis, from Ilfracombe, of a dark self-colour (chocolate or umber-brown), is constantly extending the tentacles to full four times their length imder ordinary cir- cumstances ; and on one occasion I have seen a tentacle on each side thrown out so long as to command fully a circle of six inches in diameter. After the extension, I observe that the tentacle assumes for several hours a white appearance, increasing in intensity towards the extreme tip. This ex- treme extensility is interesting, as showing the resources of the animal in commanding a larger range for feeding : and the modus operandi is no less curious; for, after having reached the utmost length, any nearer spot is examined by curling the tentacle into a variety of elegant curves and rings." Mr. E. W. H. Holdsworth has also favoured me with some interesting observations on the same curious habit. Referring to an example which he had abeady described to me in the case of S. miniata, and which will be detailed in its place,* this excellent observer says : — " Since my last letter I have seen the elongation of one of the tentacles of the first row in hellis. The ordinary shape and proportions were retained, but the arm was stretched to more than twice its natural length, yet without any appearance of imnatural tension or straining : it was constantly in motion, * See infra, p. 44. d2 36 SAGARTIADiE. apparently feeling about for something, but assumed its usual size after a few hours. It was altogether very dif- ferent from what I have observed in the case of miniatay The Daisy is prolific in captivity. Mr. Holdsworth tells me that he has known 146, 160, and nearly 300 thrown out from single individuals in one day. They appear be- tween the tubercles at the summit of the gonidial grooves ; these grooves evidently acting as ducts for the transmission of the fully-formed young from the intersepts to the exter- nal world, and doubtless for that of the ova, when these are discharged. The characteristic form and markings are dis- tinctly recognisable in the newly-bom young ; their prin- cipal distinction, besides size, consisting in the fewness of their tentacles, which are commonly twelve in number, and in the comparative length of these organs, which is much greater than in the adult. Mr. Holdsworth says : " I have observed in this species, as well as in dianthus, and \Bunodes] gemmacea, that the size of the young varies with that of the parent, — large parents producing large young ones, and vice versa. I have noticed it repeatedly ; and the fact may perhaps be accounted for by the greater capacity of the larger parent affording room for a further development of the young before they are expelled than could be admitted of in the case of a smaller individual ; for the mature ova, I imagine, are always of the same size in the same species." I have already remarked that this species is easily kept in the Aquarium. It requires, however, some caution and skill in the manner of its capture ; for, as it resides in holes and crevices of the solid rock, it cannot be worked off with the nail, like some others, but must be cut out with a steel chisel. And, unless this operation be carefully performed, there is danger of tearing away the animal from its base, the central portion of which may be left behind. In this THE DAISY ANESfONE. 37 case it will expand in captivity, and look healthy to the eye of the tyro ; but, when examined, it will be seen to be perforate, a stick thrust in at the mouth coming out at the base. Specimens so mutilated never recover. Little more than ordinary treatment is required for S. belUs. It is desirable that it should be gently pushed, base downward, into a hole of a piece of rock ; — flints are often found suitable for it ; — or, if such cannot be readily obtained, two pieces of stone may be set side by side, and the Daisy dropped between them. Then it will soon attach itself to the bottom or sides of the crevice, and expand its beautiful disk, like a broad coin, at the top. S. bellis appears to be essentially a southern form. Sir John Dalyell, in his twenty years' experience, seems never to have met with it on the Scottish Coast ; nor has it, so far as I know, occurred on the Scandinavian or Danish Coasts, nor on either shore of the German Ocean. On the south- western shores of Scotland, however, it has recently been found in some numbers. On the other hand, it has recently been obtained near Boulogne; Mr. Holdsworth finds it "by myriads" near Oporto ; Rapp and Lamarck give the Mediterranean gene- rally as its habitat ; and De Blainville, more specially, la Mer de Naples.

Of foreign species the beautiful >S^. decorata (Dana), found in tlie Lagoon of Honden Island, is closely allied to our "bellis, S. Fuegensis (Dana), from Terra del Fuego, a very fine species with rich yellow column and disk, and grass-green tentacles, has much in common with the subject of this article, but it has far more prominently the characters, that the tentacles are short, and spring isolatedly from the disk. 8. invpatiens. (Dana) has the habit of elongating the column pillar-wise, and of variously constringing and writh- ing the body ; thus appearing to be intermediate between hellis and viduata. It seems to be through hellis and Fuegensis, that the genus Sagartia leads off to the curious Discosoma nummifonne of the Ked Sea, in which the column has no appreciable height, the animal being a very thin, flat, circular plate, with the tentacles reduced to minute warts, arranged in groups which form radiating bands. Of native species >S^. parasitica and B. clavata present, in the expanded character of their disks, marked relations with hellis. But a still closer affinity exists between hellis and Aiptasia amacha, in the characters both of the disk and of the column, as I shall notice more particularly when I come to describe the latter. It ought never to be forgotten that the order of sequence which we are compelled to adopt in treating of creatures in a book — that of placing each species between two others — can by no means express all their relations. Every species stands in the midst of many others, some closer to it, some more remote, to which it is linked more or less obviously.

Below them, at the tentacle-foot, is a large space of white, which is crossed by two bars of black; the upper one thick and very constant, the lower slender, and sometimes thinned away to a mere shade in the middle. Groups of tentacles often occur of a more or less opaque white, but barred like the others, with which they form alternate clusters. Those of the outer row consist each of a pellucid sheath investing a core of scarlet or brilliant orange, resembling in appearance the central gland in the papilla of an Eolis. This effect seems to depend on the pig- ment being spread over the interior surface of the wall of the tentacle, which is unusually thick and colourless. TENTACLE ^^'^^'''' Orange-red. o^ Size. S.

It maj suffice to particularise tliese varieties, but spe- cimens are frequently found combining the characters of several, and running into one another bj imperceptible gradations. I obtained a very young individual at Wey- mouth, which I assign to this species, in -which the ten- tacles of all the four rows were cored with the richest orange. I first became acquainted with this very fine species in the summer of 1853, at Weymouth, where I found several specimens adhering to the shells of oysters and pectens, brought to market by the trawlers. Since that time I have met with it in some abundance in the neigh- bourhood of Tenby, especially on the eroded surface of some dangerous rocks, known as the Woolhouse Rocks, lying about a mile off shore, and exposed only at low water. In the pools and hollows of this reef, open to • In these compounds I take the liberty of using the elements " ventutet," '•■ rosea," and " nivea," not as Latin adjectives, but as words now having the force of proper names. 44 SAGAETIAD^. investigation only under favourable circumstances of wind and weather at the equinoctial spring-tides, this, with other lovely kindred species, as rosea, nivea, &c,, expands its beautiful blossom, in charming abundance. But still more profusely does it occur in certain situations in the vicinity of Torquay. The line of shore between the Baths and Meadfoot is very bold, and a great number of precipitous insular and peninsular rocks fringe the sea- margin. When the tide is very low, and when the sea is very smooth, a small boat can penetrate into the narrow straits and caverns formed by these fragments : and there, on their landward sides, where the rays of the sun never reach, may be seen myriads of Anemones, chiefly of this species, but mingled with dianthus, rosea, and nivea, and varied by a vast number of Alcyonium digitatum, which beneath the surface of the clear water are seen blossoming with their lovely polypes. The finest specimens I have seen are those whicli Mr. W. A. Lloyd obtains from the Menai Straits. The species seems to be specially abundant in that locality, and specimens two inches in diameter are not at all rare. The varieties ornata and hrunnea are the prominent forms. The habit referred to, under S. helUs, of greatly lengthen- ing one of the tentacles, is possessed by this species also. Mr. E. W. H. Holdsworth has favoured me with tlie fol- lowing note. " In two specimens of the Rosy-armed miniata [var, roseoides] I have observed a remarkable elongation of one of the tentacula, apparently of the second row. Under the microscope the surface appeared corru- gated [or transversely annulated], but mostly so when tlie arm was fully distended, and the corrugations were most decided at the free end, which was enlarged, truncate, and slightly dimpled at the centre. No use was made of this long arm when the animal was feeding : it hung down as THE SCARLET-FRINGED ANEMONE. 45 if it did not possess any paxticnlar function. It had the same colour as the others ; but was not, like them, wholly withdrawn when the animal was closed. In fact, it appeared as if rather in the way, and not easily disposed of by its possessor. After about a week [the phenomenon] disappeared, and I have seen nothing of the lengthened arms since, in either of the specimens that had had them." Those curious missile filaments which I have named €Uiontta* are discharged by this species in great profusion. They are, as usual, white, but appear to possess the power of discharging a pigment. A large specimen, which I had irritated by forcibly detaching it (in the usual way) from a stone, diffused a copious mucus. Acontia were also abundantly protruded, and spread to double the diameter of the body on all sides, on the bottom of a saucer in -which I had placed it. After a while the whole of this mucus over the same area icas of a delicate but decided roseate hue, as seen on the white china. The acontia are very densely filled with cnidce, of two kinds, chambered and unchambered. The former are Tonsil ^f ^^ inch in length, linear-ovate, of a clear pale yellow hue, highly refi-actile, with a long parallel-sided chamber, extending through three- fourths of the cnida. It discharges a wire (ecthoroeum) about one and a half times its own length, furnished for the distal two-thirds with a screw of two (or three) spiral bands, closely set, and forming an angle with the axis of 30" : the bands are clothed with reverted barbs. The imchambered cnidse are ^^th of an inch long, of a similar shape, shooting a wire to eight times its own length, which is attenuated to a fine point, and is furnished with a single screw-band, unbarbed. When out of water, miniata has the habit of protruding * See the Qeneral IntroductioD, for a full description of these organs. 46 SAGARTIAD^. the wall of the stomach, almost to as great an extent as B, crassicomia. This is specially seen when the specimens hang from the perpendicular face of a rock. According to Mr. Holdsworth, S. miniata increases by spontaneously separated fragments of the base, like A, dianthus. He says, — " I have had two young ones of miniata produced from hits of the base detached from a large specimen, which had been fixed for a long time. It was anchored too firmly ; so it cut its cable, and started for fresh quarters." According to the same careful observer, double individuals are not uncommon — a fact which points to a more decidedly fissiparous habit. The following note contains all the original information that I possess of the generative process. Examining a small specimen, about the middle of August, I found that it had given birth to several ova or gemmules. I had just removed it from a stone in one of my tanks, to which it had been attached many months. It had protruded the filaments copiously, and these were now partially retracted and coiled up, forming a white coat almost entirely in- vesting it. Under a one-inch objective, as these were twining and twisting, I saw among them several olive- yellow bodies, which seemed to have a motion independent of the filamental currents ; and I isolated one. It was of a sub-nautiloid form, irregularly convolute, much like a Bursaria, about xTnnjths of an incli in long diameter, Y?jWths in lateral, and about -ij^ths in transverse; of a dull clear olive, but granular, riclily clothed everywhere with small cilia, by means of which it revolved freely in all directions. Others which I saw were much less than this one. Dr. T. S. Wright, however, seems to have witnessed the birth of perfectly-formed young. " Four young ones," he observes,* " produced by as many specimens of Actinia * Proc. Roy. Phys. Soc. i THE SCARLET-FEINGED ANEMONE. 47 omata [= Sag. miniatd\ in the last six months, were horn with a double row of tentacles, the inner long, the outer short, and tinged "with orange-red as in the adult." This beautiful species is easily reconciled to captivity, and is hardy. I have kept individuals for long periods. It expands freely. It ought to be placed on a worm-eaten piece of rock, but it does not require so deep a hole as hellis. The rich hue of the column, in some varieties, makes it desirable that this should be visible. The following list of localities marks the range of the species as at present known. I am not aware that it has been found out of Great Britain. Deal, Rev. H. H. Dombrain : Weymouth, P. H.

For the first and second of these varieties, I have retained the names proposed respectively by Mr. Holdsworth and Professor Jordan, who described them as species under Ihese appellations. I am quite sure that both must be referred to this species. The fourth is the form so abun- dant on the Pembroke coast ; a very marked variety, to which I have assigned a name alluding to the Aij/tiTrai, the ancient inhabitants of that part of Wales. All are beautifal ; but perhaps pulcherrima, as its name imports, is the loveliest of all. I 50 SAGARTIAD^. There Is no doubt tliat S. miniata and >S'. rosea approxi- mate in some of their varieties very closely ; and I have had many doubts about the propriety of keeping them separate. I have seen, in the vicinity of Tenby, specimens, in which some of the small tentacles of the outer row had a scarlet or orange core, and yet in no other respect could I distinguish them from the true rosea. Normal rosece and normal mimatoi were abundant on the same rock (the Woolhouse-rock) within a few feet ; which fact suggests the possibility of hybridization. Besides the scarlet-cored tentacles, miniata may be described, in those varieties which come nearest to rosea, as darker externally; as growing to a far larger size ; as being lower and less pillar- like; and as having a much more lax, flaccid habit of body. The qucestio vexata, — What constitutes a species ? what a variety? is one which it is much easier to answer theo- retically than practically. Some have proposed certain arbitrary canons, such as that assumed by Mr. Tugwell, \hsdform distinguishes the species, colour only the variety. But this is quite untenable. In many instances colour is not only specific, but even generic ; — as black, "(^hite, and red, in well-recognised patterns and in certain fixed regions of the body, in the Woodpeckers ; black, yellow and red, again in certain patterns, in Paj>ilio ; yellow, red and white in the Pteridoi. Indeed, our entomological friends would be sorely puzzled to define their species, if colour were denied them as a distinction. In the Butterflies alone, hundreds of indubitable species rest exclusively on colouring. The fact is, anything may be a specific character, provided it be constant. Constancy, permanency, is what we require ; let us only indicate any mark that is invariably found,— no matter whether it be colom', form, pattern, surface, sculpture, or any thing else ; or any combination of THE EOSY ANEMONE. &1 these, and we have a good specific character. I believe, with Mr. Wallace, that " the two doctrines of * permanent varieties' and of 'specially created unvarying species' are inconsistent with each other."* In other words, I would say a species is permanent, a variety transitory. There is no doubt, however, that the latter may be maintained within certain limits by breeding in and in ; though there will always be a tendency to revert to the original and normal character, which marks the permanent species. Though I believe this distinction to be a good one, it does not therefore follow that we can put it in practice without any difficulty. We find a specimen; — we know nothing of its antecedents ; — at most we can trace it only through a few generations ; and thus we are precluded from applying our test of permanency to it. The only resom'ce is the practical skill and judgment which expe- rience and observation gradually give ; and these, as they cannot be communicated to another, nor be reduced to formula, differ indefinitely in individual cases. In the present work I must beg my readers to believe that I use the best light I have, to arrive at right conclusions. Under all its variations, which are not very numerous, JS. rosea is a lovely little species. When left by the receding tide, it protrudes from its tiny cavity in the over- hanging rock, and droops, a pear-shaped button of orange- brown, with a cluster of brilliant purple tentacles just showing their tips from the half-opened centre, and a drop of water sparkling like a dew-drop, hanging from them. Then it is beautiful. But a more charming sight is seen when, as at the rock near Lidstep, or on the Woolhouse reef, you gaze down into a narrow basin worn by the waves of ages in the solid limestone, and, having first care- fully lifted the broad fronds of Laminaria and Bhodymema * Zoologist, p. 5S88.

It is equally attractive in those imitations of such rock- pools, which we make in glass tanks and china pans for our drawing-rooms. But, like the other species of the group to which it belongs, it is a somewhat precarious tenant of the Aquarium. I have kept at different times a large number of specimens ; but none of them, so far as I can remember, survived a twelvemonth's captivity. A dark-coloured mass of rock suits it best, serving as a back- ground for its rich crimson blossom. It loves the shadow, too; and should therefore be placed on the side farthest from the light. A rough perpendicular surface is very appropriate for it. The Rosy Anemone occasionally protrudes the walls of the stomach, like B. crassicorms, which then overlap the disk in large furrowed pellucid lobes. It sometimes -distends the tentacles till they are translucent, and then it is not uncommon to see the free ends of the acontia, lying within these organs in coils, having penetrated through the open base of the tentacle from the intersepts of the body- THE ROSY ANEMONE. 53 cavity. One may sometimes also discern fragments of the same filaments, which have become accidentally detached, driven to and fro at the tip of the interior of the tentacle. The proper ciliary motion of these twisted atoms combining with the motion produced by the lining cilia of the tentacle- wall, gives them the fitful vacillating action of spontaneous volition ; so that they may readily be mistaken for living worms accidentally imprisoned. The acontia are emitted from the pores of the body in great profusion upon irri- tation. The form and armature of their cnidce do not differ from those in the species last described.

This attractive little Anemone appears to have been seen only hy Mr. HoldsTvorth, who described it in detail, "with accompanying di'awings, in a Memoir read before the Zoological Society of London, Dec. 11th, 1855. From those details, as published in the Society's proceedings, I have compiled the above description, merely throwing them into that order of arrangement, which, for convenience of reference, I have adopted in this work. I have been aided, however, by the original beautiful drawings, which my friend has liberally placed in my hands. From these, the figures in Plate II. have been likewise copied ; fig. 9 re- presenting the flower, fig. 10 the button.

The first (of the variety stihista) I found on an oyster in the fish-market at Weymouth, in the summer of 1853. As the oysters with Avhich the market was supplied were brought in by a trawler, whose fishing grounds were West Bay, and the offing of Weymouth Bay, we may safely set down one of these as the native locality of my little prize. The second specimen, which exhibited that measure of diversity in colour, that I have set down as distinctive of the variety astimma, but exactly agreed with the former in all its other characters, and was manifestly, at the first glance, of the same species, was sent me from Torquay, in April, 1856, by the Kev. W. F. Short. I understand it was taken at the insular rock knoAvn as the Ore Stone. Though less showy than the former specimen, whose black-lined face and pouting scarlet lips made it very attrac- tive, this latter was still very pretty ; and it proved to be easily reconciled to captivity, for it remained in one of my tanks, — sometimes under rather unfavourable conditions of the water, — from the 10th of April, 1856, to the middle of August, 1857, a period of sixteen months. Nor have I any reason to believe that it would have died then, but for my own carelessness ; for having taken it out of the tank to examine it, I incautiously left it, after my observations, exposed in a saucer to the midday beams of a hot August sun, and found it, of course, killed, when I looked at it again. THE FISH-MOUTH ANEMONE. 59 The (icontia contained, as usual, both unchambered and chambered cnidce. The former were linear-oblong, gioth of an inch in length, discharging an ecthorceum, four times as long as themselves, surrounded with a single spiral band. The latter were of the same form, but twice as long and wide, discharging an ecthorceum very little longer than themselves, in which I could not discern the least trace either of barbs or screw. The acontium was taken, certainly, from the specimen last mentioned, when it was either dying or dead, decomposition having commenced ; but the invest- ing cilia were in parts still active, and the cnidce dis- charged vigorously, just as when alive. In both varieties the small, conical, pointed tentacles projecting very regularly from the margin, impart a pecu- liar and well-recognised character to the species. These organs so strongly resembled the little sharp teeth crowded round the jaws of some fishes, that I was induced to borrow a nomen trivicde from that resemblance. The appellations of the varieties allude, as my classical readers will have perceived, to the long-standing custom among the Oriental ladies (nor altogether unknown to the dandies of ancient Kome*) of staining the eyelids with stibium, a preparation of antimony, for the purpose of imparting a soft voluptuous languor to the eyes.

Hollows in perpendicular and over- hanging rocks, exposed at low water : dark tide-pools. Vakieties. The variation seems to be limited to the greater or less depth of tint in the column. This most elegant species was first met with by myself in the neighbourhood of Tenby, where it is so abundant as to be quite characteristic. It has since been found in several other somewhat remote habitats, but nowhere in anything like the profusion in which it occurs in that its first recognised home. I am justified therefore in consider- ing South Wales the metropolis of the species. It occurs all along the south coast of Pembrokeshire, at least from Monkstone Point to St. Go wan' s Head ; but is more than usually numerous in the fine perforate caverns of St. Catherine's Island, that form such an attraction to Tenby visitors, and in the hollows and erosions of that rich pre- serve of zoophytic game, — the Woolhouse Eocks. The Orange-disk is essentially a cave-dweller ; almost invariably choosing for its residence some crevice or cranny, or one of those little cavities made by boring moUusks, with which the limestone on those coasts is generally honeycombed. Occasionally, indeed, we find it in shallow pools, with a bottom of impalpable mud, the detritus pro- duced by the action of the waves on the surrounding rocks ; but in such cases it will be invariably found that the Actinia is attached to a hollow in the solid floor of the pool, protruding its body through the deposit by elongation, and expanding its beautiful disk on the surface. Owing to this 62 SAGARTIADJ;:. troglodyte habit, it is, like many of its congeners, rather '■ difficult to procure, notwithstanding its abundance, as it must be chiselled out, — an operation, which, from the great hardness of the compact limestone, is both tedious and precarious. Hundreds might be seen* in the largest of the caverns just alluded to, hanging down from the walls during the recess of the tide ; the button elongated to an inch or more. And almost every dark overarched basin hollowed in the sides of the caves, or in similar situations, at Lidstep, at St. Margaret's Island, and under Tenby Head, each filled to the brim with still crystalline water, had its rugged walls and floor studded with the full-blown blossoms of this 9,nd cognate species. As a specimen of the exceeding richness of these " gar- dens of the Nereids," wherewith our iron-bound coasts arc adorned, I shall take the liberty of citing the description of one, as it appeared to myself in the vicinity of which I am speaking. It w^as on the face of the blufi" castle- crowned promontory known as Tenby Head. " After scrambling over many rough ridges, we come to a perpendicular wall of rock some twenty-five feet high, jutting out from the cliff right across our way ; its foot Avashed by the sea, which is evidently of considerable depth, its summit tapered to a sharp edge, and the whole side holed, and furrowed, and honeycombed, and covered with barnacles to the very top. * I use the past tense ; for alas ! it is so no more. WTieu I revisited Tenby in 1856, I found that these caves, and almost every accessible part of the neighbouring coast, were pretty well denuded of the lovely animal- flowers, which, in 1854, had blossomed there, as in a parterre. I fear that the hammers and chisels of amateur naturalists have been the desolating agents ; and my friends tell me, not without a semi-earnest reproachful- ness, that I am myself not guiltless of bringing about the consummation. If the visitors were gainers to the same amount as the rocks are losers, there would be less cause for regret ; but owing to difficulty and unskilful- ness combined, probably half a dozen Anemones are destroyed for one that goes into the aq[uarium. THE ORANGE-DISKED ANEMONE. 63 " On the south side of this wall, almost at its tase, on a rough mass of rock so covered with luxuriant tufts of Dulse {Rhodymenia palmata) as to be richly empm-pled with it, I found a little basin, somewhat irregnlar in outline, but rudely oval, about a foot long, eight inches wide, and sis inches deep ; in other words, about the size of a soup- tureen. It was much obscured by overhanging drapery of Fucus ; but, on lifting this, I was astonished and delighted with the profusion of animal life, whose gay and varied hues gave to the tiny area the appearance of an artist's newly-rubbed palette. "Lest I should seem to exaggerate if I reported the contents of this basin from memory, I took the trouble to count the specimens, noting each sort in my pocket-book on the spot. Their numbers were, — nineteen of the bril- liant Orange-disk [Sagartia veimsta), and twelve of the Snowy [S. ntvea), all fully blown ; besides two large Shore- Crabs [Carciaus moenas), a Shanny {Blennius pholis), a Cynthia J several Sabellce, a gi'oup of Sabellaria alveola fa, some very fine masses of Botrylloides, and many specimens of the Crown Sponge {Grantia ciliata). " Nor was this extraordinary pool less rich in its botany than in its zoology. Chondrus crispus, finely tipped with Bteel-blue, as usual ; the Common Coralline ( Corallina officinalis), purpling the sides and bottom ; some small fironds oi Rhodymenia palmata, and one or two tiny ones of Laminaria saccharina, — which is particularly pretty while it is young, — were there ; as also two other kinds of superior elegance, namely, Delesseria rascifolia, with its oak-like leaves of fine dark crimson, and the pretty rich-green feathers of Bryopsis plumosa. Besides all these, there were other plants and animals of less note, which I did not enumerate." * * Tenby ; a Sea-side Holiday ; 96, et teq. 64 SAGARTIAD^. I think it more than probable that the long deep Atlantic fiords of the sister island, will, on examination, prove at least to equal, if they do not greatlj surpass, in the luxuriance of their marine zoology and botany, any- thing that we can boast in England. As a companion to the above, I gladly give an Irish picture of 8. veniista, in situ, sketched by the graphic pen of my friend Dr. E. Per- cival Wright, the able and energetic Director of the Dubliu University Museum. " Last August, while entomologizing with Messrs. Haliday and Furlong in Killarney and GlengarifF, we made one day's excursion down Bantry Bay — a famed spot, but, with all its fame, it has never been worked. Well ; the weather was bad, — very bad ; a thick mizzling rain soon bespangled us with heavy dew-drops : however, pulled by four good oars, we did get on. The tide being right against us, it was hours ere we reached some remarkable caves, — the chief object of our trip. " Thousands of the dark olive-green Actinia mesembry- antJiemum lined these caves. It was not safe to try to land ; but in places where the sea, owing to shelter, was quiet, I could see the sea-floor covered with an extra- ordinary luxuriance of Actinise, Sponges, &c. ; — their colours, and forms, of course, distorted by every ripple of the waves. " We did land for a few minutes on one spot ; and, even at Tenby, and under St. Catherine's Rock, I never saw so much in the time; and this, though I did not wander from a single rock-pool. In it I saw about four and twenty specimens of Echinus lividus, all comfortably sitting in arm-chairs nicely cut out of stone, and most of them of a lovely purple tint. Down the centre of the pool ran a narrow fissure quite clicked with Bunodes crassicornis, which, as is their wont, had managed to gather all the THE ORANGE-DISKED ANEMONE. 65 little broken debris of shells, and to stick them over their bodies, in the way children stick broken china on heaps of mud, in our Irish villages. " But new to me as was E. lividus, and splendid as the really fine crassicornes were — they were of that pretty healthy white and pink variety — yet they were surpassed by your Sag. venusta, which with S. rosea sprouted out of every fissure. The former is, I think, the most exquisite of our Irish Anemones. In your figure in ' Tenby,' the tentacles are hardly white enough, and no painting can do justice to the clear orange. Book it and S. rosea, both very distinct from any other of our species. I saw other Anemones that I suspect will turn out new species ; but what could twenty minutes and an insect-net effect in 'catching' such things as Sagarts? Why, touch them roughly and — they're gone! If spared, I will visit them again ; and you shall see them, I hope, too : for if I spend a month in Bantry Bay, say next June or July, I can easily send you my Actinia captures ; — that is, if you won't visit Ireland. It is as pleasant as Jamaica." To turn firom these tempting scenes of wild nature ; — our beautiful Orange-disk is easily made happy in captivity : where, indeed, fed daily by fair fingers, and admired by bright eyes, it would argue badly for its temper if it were not. It is soon at home, and becomes one of the most brilliant ornaments of the Aquarium, expanding its lovely disk freely, fringed with its elegant border of snow-white tentacles, and thus making up in beauty what it lacks in size. It will survive an indefinite period, if it receive a moderate degree of attention. The observations which I have made on the treatment of S. rosea will apply with equal force to this species and to the following. Mr. Holdsworth informs me that he has witnessed the production of new individuals from fragments spontaneously 66 SAGAETIADiE. detached from the "base, in S. venusta, as before described in the case of A. dianthus. .Miss Loddiges has favoured me with information of the same phenomenon in this species. The following are the localities known to me as inhabited by the Orange-disk : — Guernsey, Dr. J. D. Hilton : (on Laminariee washed up) Miss Guille : Torquay, P. H. G. ; Clovelly (on oysters from deep water), Bev. C. Kingsley : Morte Stone, O. T. : Lundy, G. T. : Tenby, P. H. G. : St. Gowan's Head, P. H. G. : Puffin Island, E. L. W.: Bantry Bay, E. P. W. : Belfast (abundant), C. Bosanquet. This species has close relations with S. nivea. Its colouring, however, so far as I have seen^ is constant, without any approach to albinism ; and its tendency to an ovate outline also distinguishes it, though less satisfactorily. It may possibly be found hereafter that the two constitute but a single species; but in the absence of any intermediate condition, I think it best to consider them distinct. miniata. VENUSTA. nivea.

This variety sometimes has the column of that rich orange-brown hue which is characteristic of this group. It was on the north side of the limestone promontory- known as Petit Tor, on the south coast of Devon, that I first met with the Snowy Anemone, in the spring of 1852. The rock here is hollowed into large cavernous pools, isolated only at very low tides, and dark with the shadow of the slimy sponge-covered precipices that arch over them ; where Laminarice grow abundantly, affording many a nidus for profuse forests of parasitic Hydroids of the genera Sertularia, Pliumularia, and Laomedea. The little red siphons of thousands of Saxicavce hang down from the holes which they have excavated in the solid limestone, each terminated by a diamond drop of water, awaiting the moment when the returning tide shall cover their abodes, and restore to them activity ajid enjoyment. It is their season of periodical idleness and repose. Among the roughnesses of the rock, and the conical papillary pores of the sponges, which, olive, yellow, and scarlet, stud the sur- face, — green Nereidous worms glide along, in and out, by means of the curious packets of slender bristles, alternately projected from every segment and withdrawn, that serve them instead of feet. Below the water-line, that is to say, THE SNOWY ANEMONE. 69 the level of the lowest part of the margin of the pool, which of course never varies, such animals and plants as require to be perpetually covered with water enjoy circumstances suited to their wants. In the deepest shadow, fine speci- mens of the fleshy Dulse {Iridaea eduUs), and the lovely leaf-like Delessena sanguinea, display their crimson fronds in copious tufts ; plants that cannot hear the absence of water, their delicate leaves becoming orange-coloured in large patches, which soon die and slough away, — if left nnbathed even for a single tide. The curious white Cows' paps [Alcyoniuvi digitatum), all studded with their clear glassy polypes, project from the rock ; and here I saw several white Acttmce, which at once attracted my notice, though beyond my reach, on the opposite side of the pool. At length, however, by searching in another smaller pool, to which I could gain access, I found, beneath the drooping Oarweeds, one of the white Actinice within reach. It was three or four inches beneath the surface ; so that to procure it, it was needful to bale out the water to that depth, which I effected by the aid of one of my collecting jars, and then to cut out the animal's cell with the steel chisel. I was, however, sufficiently repaid for the labour by the beauty of this snow-white Anemone. After an absence of nearly six years, I visited this inter- esting spot again. It had often been a subject of specula- tion with me whether the minute featm-es of a rocky coast change rapidly under the action of weather and sea ; and I had looked forward to this visit with interest, as likely to afford me data for determining the question. The shore was as if I had left it but yesterday. Everything appeared as if it had been untouched : every tide-pool, every projec- tion, I recognised : the broad cleft that I have described (Devonsh. Coast, p. 34) ; the little basins within it ; the slight projections on the face of the cliff by means of which 70 SAGARTIAD^. I scrambled across, just as of old ; tlae fartlier cliasm (p. 39) ; and tlie large dark tide-pool Inwhicli I had seen the Prawn; — all were exactly as when I first made acquaintance with them six years ago. This last pool is still fringed with Oarweeds crowded with Laomedea forests, and the farther walls are still spotted over with daisy-like Snowy Ane- mones, just where I saw them first, and in all probability the very same identical individuals. But in the interim I had become familiar with the fair nivea, in what I may call its metropolitan home. It is in the numerous caverns and dark rock-pools into which the limestone formation on the Pembroke coast is hollowed, that this lovely species is seen to advantage ; especially in the dark holes of Monkstone, the Caves of St. Catherine's and St. Gowan's, and the oversliadowed pools of Tenby Head and Lidstep. Here, as we peer into the clear water of these obscure wells, we see the Snowy Anemone studding the rugged sides by hundreds, like bright stars on the mid- night sky, singly and in constellations. Here, too, swarm its congeners and companions, the equally lovely rosea and venusta / and this trio of graces are the very gems of the Demetian rocks. When covered by water, m'vea expands freely, and con- tinues long unfolded ; but^ in situations where it is left by the tide, it either withdraws into its hole, or, if this be placed on the side of a perpendicular or overhanging rock, it hangs out in the form of a lengthened wart, with a drop of water depending from its drooping head, like a dewdrop, in the centre of which a speck of white reveals the peeping tips of the contracted tentacles. Mr. Holdsworth has observed in this species that curious form of elongation of the tentacles described under S. miniata. Here, however, no fewer than ten or twelve of the tentacles of the first and second rows hung down, THE SNOWY ANEMONE. 71 straight and motionless, to a distance of two inches from the disk, Thej were attenuated towards the middle, enlarging again on nearing the tip, which was truncate in some^ rounded or obtusely pointed in others. Corrugation was present in some, but was rather difficult of detection, owing to the absence of colour. It is probable that this peculiar condition of the tentacles maj be accompanied with func- tions distinct from those of the mere elongation, such as has been described under S. hellis. (See ante, p. 35.) This species bears a far closer resemblance to a daisr, both in size and colour, than that which has obtained pos- session of the name. Indeed, one can scarcely see a group of mvecB and venustce under water, especially among the small mossy growth of grass-green Algfe, — Bryopsis, Con- ferva, Calothrix, Enter omorpha, &c., — without being forcibly reminded of a crop of daisies on a lawn. Mr. Holdsworth finds it "not uncommon at Dartmouth, but usually small ; inhabiting crevices in steep rocks under sea-weeds; at Guernsey, in sheltered nooks, very fine." The young do not difier from the parent, except in size and in the number of the tentacles. An infant specimen that was bom in one of my aquaria, adhered by the base immediately, and presently expanded. It displayed twelve tentacles, set in six pairs ; each pair being nearly parallel, and separated by a marked inteiwal from the pair on either side. Nivea rivals miniata in the profusion with which it shoots forth its poison-bearing acontia, on the slightest irri- tation. They are moderately crowded with cnidce, mostly of the chambered kind, discharging an ecthorceum little longer than themselves, densely armed with reverted barbs, which impart the brush-like form so characteristic of this genus.

Disk assuming various shades of yellow, from a pale chrome or lemon-colour to a deep orange, or even dull vermilion. This pretty little species was discovered by myself at Ilfracombe, It was during an unusually low spring- tide, in October, 1852. Specimens occurred at that time in two localities, having this in common, that in each case they were adherent to the perpendicular or overhanging surface of the cliif, at the very verge of lowest water. The animals were social : in the one case I found three indi- viduals associated ; in the other many dozens, a numerous colony thronging the approximating sides of a narrow fissure that runs far up into the solid rock at the seaward base of Capstone Promenade. A frequent tendency to a pendent posture was noticed ; for even where the general surface of the rock was perpendicular, many of the Ane- THE SANDALLED AXEMONE. 75 mones were hanging from Taeneatli the little points and projecting ledges. In describing these specimens, I suggested the possibility I tiiat they might be referred to the Actinia alba of 3Ir. W. P. Cocks.* The absence of the bright yellow dots that were found on the mouth of the latter, and the entire want j of visible suckers, induced me to consider mine as unde- scribed. It is true, the repeated occurrence since of specimens with a disk more or less yellow nullifies the force of the former objection, but the latter remains ; and until I see specimens of A. alia from Mr. Cocks's locality, I dare not assume the identity. From original drawings with which that gentleman has kindly favoured me, I per- ceive, moreover, that the tentacles in alba are numerous and slender, whereas in spliyrodeta they are few, tliick, and conical. Besides this, the marking of the ten- tacles in alba, which are described as " barred, having opaque white patches anteriorly," removes the animal from any species with which I am acquainted. I am not, however, without hope, that before this work is closed, the kindness of my Cornish friends may bring me into personal acquaintance with this, and other desiderata of that prolific coast. The substitution of another appellation for that which I had at first assigned to this species was called for on two accounts. First, there was already a species named Candida by Miiller; of which fact I was not aware. Secondly, this name proved objectionable. While no specific name may be rejected on account of its having no significance, every one ought to be rejected which has a false sig- nificance. Mr. Holdsworth's discoveries of the species at Dartmouth and in the Channel Islands have proved, or at • Johnst. Br. Zooph. ; Ed. 2; 217. Eep. Comw. Polyt. Soc. ISal; 6. 76 SAGARTIADiE. least rendered it highly probable, that the normal con- dition is to have the disk of a yellow hue, more or less deep, the white variety being nothing more than the albinism to which organic colours so often tend. The term " candidal'' therefore, became inappropriate as a nomen triviale ; and I have sought one which should express a more unvarying character. The word " sj)hy- rodeta''^ signifies sandalled, from a^vpa, the ankles, and Beco, to bind ; and alludes, as I need scarcely say, to the line which, like a narrow ribbon, encircles the tentacle-foot. That the white disk marks a degenerated condition is rendered more probable by some facts that have come under Mr. Holdsworth's observation, and, in part, also under my own. A specimen obtained by that gentleman at Dartmouth was at first of a rich chrome-yellow over the whole disk ; but after having been some time in captivity, it gradually faded to a sort of dull cream- white ; in this condition, my friend submitted it to my care for a few days, during which time it quickly resumed its brilliant face. Another individual, which I think Mr. Holdsworth brought from Guernsey^ fell into a like condition. Writing of this, he observes, *' The animal has been out of sorts, and I have been obliged to administer to it several draughts (of pure sea-water), which have nearly set it to rights again. The beautiful colour of the disk, however, has nearly vanished, but some traces of it are still to be seen around the mouth. When I first had it, the colour was very conspicuous." The Sandalled Anemone is an interesting little captive. It expands its flower-face with great readiness ; rarely remaining long closed, provided the surrounding water be pure. The large conical tentacles stretch out hori- zontally to their utmost, like a star ; and though, on being touched, it will partially contract, it unfolds the instant I THE SANDALLED ANEMONE. 77 the annoyance ceases, and is presently fiill-blown again. It is fond of floating at the surface of its prison, the base dilated at the top of the water, like a swimming Nudi- branch, the body hanging downwards, with the tentacles widely expanded. It cannot be considered a common species ; but where it does occur, it is usually in some numbers. It is easily obtained when discovered, as it does not inhabit holes or crevices, but adheres to the smooth rock; it does not appear to indue its body with gravel, or any extraneous substances. Mr. Holdsworth found it not uncommon at Guernsey, with the unexpected habit of lodging under stones on the beach, at low water. At Dartmouth the same observer records its occurrence on the roots of Laminaria, as well as on the rocks. In my original notice of the species, I have mentioned the readiness and profusion with which the acontia or armed filaments are shot forth from the body on the slightest provocation. Subsequent observation has abun- dantly confirmed this irritable habit. The character and armature of the cnidce, are also there noted. The localities of the species are as yet but few, though they are widely scattered. Jersey, Guernsey, E. W. H. H. : Dartmouth, E. W.H.E.: Hfracombe, P. H. G. : Hilbre Island, E. L. W. nivea.

I am indebted for mj knowledge of this little form to Mr. Holdsworth, who discoyered about a dozen specimens scattered about the rocks near the entrance to Dartmouth Harbom', " a part of our western coast, which, from its steep rugged character, and its liLxuiiant growth of sea- weeds, presents a fruitful hunting-ground for those in search of marine productions." They were obtained in Julj, 1855, and were described bj their discoverer, in a Memoir read before the Zoological Society of London in the following December, and subsequently published in their Proceedings. All of the individuals were of the variety cana, differing in no respect among themselves except in size. " They were found on the exposed surface of perpendicular rocks at about half-tide mark ; and when out of the water and contracted, were very difficult to dis- tinguish, owing to their great transparency." * Some time afterwards the same gentleman obtained several specimens of a little Anemone which agreed with his former captives in every respect, save that their column was of a rufous hue ; the tentacles, however, having the same characteristic foot-marks as before. He concluded • Pi-oc. ZooL Soc. 1S53. 80 SAGARTIAD^. that they were but varying phases of the same species ; and, as he kindly gave me an opportunity of forming a judgment by presenting me with a specimen of each colour, I concur with him in this opinion, and have accord- ingly so represented them. Some of my friend's observations on this minute species, — made in the course of a correspondence concerning its claim to be so considered, — will be read with interest. " Pallida is certainly not Candida [= sphyrodetd\. I have now seen, and know both well, and can readily point out the distinctions. Pallida may be easily taken for a young dianthus at first sight, having a smooth skin, with a rather erect body, and long pellucid filiform tentacles The basal rings on [? around] the arms of pallida are even narrower than in Candida, and have no direct communi- cation with the edge of the disk ; nor is there any appear- ance of a spot; their colour is almost black, but with a purplish tinge. The disk is quite transparent. The original specimens were almost colourless, but later captures were of a reddish buff, like some of dianthus ; and one of these, not more than half an inch in expanse, produced about a dozen young ones, about an eighth of an inch in height, — slender little things, with tentacles almost erect. They resembled their parent in form and colour, as far as could be seen in such minute creatures. There was no other Actinia besides the red pallida in the glass at the time, and the young ones adhered to the side of the glass vase, immediately surrounding the larger specimen, so that I had no doubt of their origin I have more than once suspected that pallida was merely the young of dianthus : but surely the latter would not breed when only half an inch high." I may add that the characteristic lines of blue, though minute, are a suflScient distinction of the species. THE PALLID ANEMONE. 81 In my limited opportunities of investigating this Ane- mone, I found it impatient of liglit, and sufficiently loco- motive. A specimen, adhering to the upper surface of a flat stone, I put into a tea-saucer ; it immediately crawled to the edge of its stone, glided round, and passed under, till it was quite out of sight : it thus traversed about thrice its own length in a quarter of an hour. I then turned up the stone, and the animal presently crawled off to the bottom of the saucer : closed all the time, except that the tips of its tentacles were protruding. Its manner of crawling was somewhat curious. It gradu- ally distended a portion of its body, which then was swollen, and quite pellucid, having a strange appearance, owing to the white china shining through the tissues of the distended portion. Then this part, being raised from the bottom so as to be loose, was pushed out and took a fresh hold, and the other half was rapidly pulled up to it, when the ante- rior half began again to distend instantly, and proceeded as before. The progress could be easily watched with a lens^ over the minute specks of the bottom. It was impos- sible to witness the methodical regularity of the process, and the fitness of the mode for attaining the end, without being assured of the existence of both consciousness and will in this low animal form. At night I found it had marched about three inches, or twenty-four times its own diameter, in six hours : but its progress, while I watched it, was much more rapid than this.

THE TRAXSLUCEST ANEMONE. 83 This species I know only by the descriptions and figures of Mr. Joshua Alder, who has kindly put into my hands, not only the published '• Catalogue of the Zoophytes of yorthumberland and Durham," in which it first received . name and place among our Anemones, but additional notes in MS., and sereral original drawings. AU these I have used in my diagnosis and figure. The name ** pellucida,'' originally applied to this little animal, having been preoccupied, Mr. Alder proposes that it should be called "^jira." Little is known of its history. Its discoverer observes of it, — " It has occurred to me two or three times at Cullercoats, on old shells, — crusted shells of Fusus anti- quus from deep water, — nestling among the Serpulae and Barnacles with which they were covered- It is so incon- spicuous, when contracted, as to elude observation ; and it was not till the shells had been some time in sea-water, and the Actinia became expanded, that its presence was detected. A specimen kept in a vase was very restless, shifting its place continually, and often changing form." It seems to be somewhat rare. Mr. Alder has seen but three specimens. ^Ir. E. Howse has obtained it once or twice from the five-men boats, on the same coast. His specimens were slightly larger than iMr. Alder's. sphyrodeta. PUEA. pellucida. I g2 ASTRjEACEA. SAGARTIADjE.

Each radius bears two white lines, — one parallel and close to each edge, but separated from its neighbour by a fine line of the ground colour : this gives an appearance as if every radius were divided from its fellow by a pair of white lines.

Laminarian and coralline zones. I owe my acquaintance with this attractive little species to the kindness of !Mr. Charles W. Peach, who forwarded to me, in April of the present year, four or five living specimens attached to an old pecten-valve from deep water ofi" the Caithness coast. The same gentleman has since favoured me with sketches of manifestly the same species, which he made from the life, during his residence in Cornwall. It was first described hy Mliller, in 1777, and figured in his magnificent work on the animals of Den- mark. Dr. Johnston included it in his second edition of " British Zoophytes," on the authority of Edward Forbes, who found it on the coast of Ireland, " on rocks 86- SAGARTIAD^. and sea-weeds;" but added no other information to the description of Miiller, which he quoted in the original Latin. An expression in this, which had puzzled me not a little, became graphically descriptive when I saw the living animal. Miiller says that the tentacles '' seem com- posed of an eye furnished with exceedingly slender rings crowded together," — a comparison which at first seems little applicable to such organs. But, in fact, they are frequently contracted into very low cones or warts ; when, viewed from above, they present the appearance of a number of fine rings surrounding the central point, very much like the eye-spots in a butterfly's wing. (See left- hand figure above.) The colony in my possession consists of one of the size and character that I have described above, and several minute ones around it, none of them so large as a small pea. Since I have had them, two or three more have been produced from the largest, from the size of a grain of sand to that of a poppy-seed. I believe all of these are the result of a spontaneous separation of fragments from the base, and not of a generative process. The most minute displays its circle of tiny tentacles. The outline of the base is exceedingly variable: it projects in ragged promontories and rounded points, which continually, though slowly, change their form and relative proportions. From some of these, minute fragments sepa- i'ate, which soon become independent animals. It is possible that the Actinia lacerata of Sir J. Dalyell may be this species; but I rather incline to identify it with our viduata. The sinuous outline on which he relied rather indicates a condition than a species. Though the short conical form of the tentacles is charac- teristic, yet occasionally they assume a lengthened slender shape, their markings becoming evanescent. Miiller THE EYED ANEMONE. 87 describes the animal as " changing place by the aid of its tentacles ;" I find it rather given to wandering, but not in this manner, which I have never seen an xA.ctinia use (his phrase "utt congeneres" notwithstanding), but by the extension and contraction of the base.

The pattern, which is pretty constant, is produced by the following elements :— each primary radius is greyish-white from the B-mark of the tentacle-foot, about half-way to the mouth ; then there is a patch of black inclosing a spot of white (often very bright), and then a narrow line of pale yellow or drab, edged with black, brings the radius to the lip. The secondary radii have the same pattern, but more attenuated. Tentacles. Pellucid grey, crossed by three (or four) broad rings of pellucid white, of which the lowest is undefined, and is frequently tinged with buff or orange. At the foot of each tentacle is a black mark con- TENTACLE OF S.

Mouth. Generally whitish. Size. Large specimens attain a diameter of an inch in the coltunn, and two inches in expanse of flower : the height is sometimes two inches and a half, but more commonly it does not exceed an inch.* * Mr. Holdsworth, in one of his letters, has drawn a pen-and-ink sketch of one which was protruding to a height of two inches from the sand at the bottom of his tank ; and states that, as the sand was full two inches thick, and that, to his belief, the troglodytes was attached,— it must have been four inches long. 90 SAGARTIADJE.

(Cheshire Coast. Lady Cust in litt.) From tlie above list it will be readily perceived that there is no species of our native Anemones that approaches * I describe it as I see it ; but Mr. West, to whose liberality I am indebted for this, as for so many specimens of this species, informs me that it Ls now in a deteriorated condition. Originally it was a very rich full lake or dark lilac. 92 SAGARTIAD^. this in Protean variability. And yet there is, in general, no difficulty in determining the species ; the characteristic B is an excellent note of distinction wherever it is present ; and in those varieties in which it is obliterated in the evanescence of the markings, as in vars. fx, v, ^, o, or merged in the abnormal spread of the dark hue of the disk, as in vars. tt, p, cr, v, the true character of the specimen will be betrayed by the form and substance of the body, the drab colouring of the column, or the tendency of the tentacles to assume the orange hue.* It is one of our most generally distributed species, rang- ing apparently all round our coasts, from east to west, and from north to south. It is also tolerably abundant, at least in many of its localities, though less liable than some to be seen by casual observers, from its habits of retirement. Mr. Price well characterised it, when he proposed for it the name of troglodytes (" cave-dweller," from rpcoyKr), a cavern, and 8vv(o, to enter) ; for its favourite habit is to ensconce itself in holes and crevices of the solid rock, into which it retreats on alarm. In the shallow pools that floor the largest of the caves at St. Catherine's, Tenby, the vars. scolojaacina and aurora are abundant, especially the former, spreading their pretty blossom-faces at the bottom of the clear water. And yet it is not easy to discover them even when scores are thus exposed ; for the mottled colouring of the disk and tentacles is so like that of the sand and mud of the pools, that even a practised eye may overlook them without the closest searching. They often protrude the tentacles only, clustered perpendicularly, through the mud, and sometimes only the tips of these organs. Their concealment is aided by the fragments of sand, gravel, and broken shells, that * " In addition to these characteristics, I think the stout firm texture of the base a fair mark, as it is not so readily injured as in most species. Also the comparatively slight adhesion, at least when you can get fairly down to it : I think it generally yields to careful fingering." (F. H. W. in litt.) THE CAVE-DWELLING ANEMONE. 93 adhere to the suckers of the column ; these foreign bodies are often present in considerable quantity, and are pertinaciously retained for a long time, even in captivity. Its general resort is not very low; from ebb neap-tide downward may be considered its range: but the var. aurora affects a much higher level, habitually dwelling near high-water mark, but then it is invariably in some little hollow of the rock in -which the water stands. Several of the varieties have been found at Morecambe Bay, by my friend Mr. F. H. West. He describes the locality as "a low, flat, sandy shore, remarkably dreary and uninviting for the sea-coast, and without so much as a rock in sight. The tide goes out a considerable distance ; perhaps three-quarters of a mile, or even more, laying bare an almost unbroken expanse of what is rather mud than sand, very soft and tenacious. Towards the south side of the Bay is a spit of firmer ground where a few stones are nncovered, which can hardly be dignified with the name of boulders, since any of them may be turned over without assistance. Attached to these we find A. dianthus, both the pure white and orange varieties, mostly young. In the course of an hour we found numerous specimens of these, several varieties of troglodytes, some rather pretty pied sorts oi crassicornis, ?Lndi of course the covarxionmesemhryanthemum. Several kinds of EoUs, as coronata, papillosa, Drummondi, and pelluctda, are found here : — Sabella in abundance ; and Sertularice, various. There are no rock-pools ; but in the sandy hollows are Gobies, Blennies, Fifteen-spined Sticklebacks, and Pipefishes ; not to mention young Con- gers, that flop and flounder about when disturbed with most unpleasant energy. . . . All the troglodytes, including the orange-disked, present themselves through the sand, much elongated, — the point of attachment being 94 SAGARTIADJi. sometimes three or four inches below the surface. They are all equally sensitive, shrinking on the slightest alarm." Mr. Holdsworth found the species under circumstances which deceived him into the belief that it was a per- manently free form, and he accordingly named it Scolanthus sphcero'ides* " The specimens were found near low- water mark, imbedded in the fine chalky mud which fills the crevices of the rocks at Seaford, their expanded disks being just level with the surface, but so nearly covered that only a faint star-like outline was visible ; on being touched they instantly disappeared ; and so great was tlieir power of inversion and contraction, that on digging carefully, they were generally found about one-and-a-half inch deep, and having that peculiar bead-like form Avhich has suggested the specific name of sjphceroides. There was usually a depth of six or seven inches of mud below them ; so that they could not have been fastened to the rock ; and since I have had them at home, now nearly five weeks, they have not shown the least inclination to attach themselves to the gravel, or glass sides of the tank in which they are living ; three of them have burrowed into some sand on which they were placed, but the others remain on the sur- face and are but rarely contracted. Soft mud is probably their natural habitat, being the most easily penetrated; and I could find no traces of any of these animals in a con- siderable tract of sand only a few yards from the locality whence these were obtained." My fi-iend was subsequently convinced that he had been misled by the appearance of the specimens : he examined them with me, and kindly gave me one of his original specimens, and we were both convinced that they were of this species. The apparent perforation at the rounded pos- terior extremity could have been nothing more than the * Proc. Zool. Soc. ; May, ] 855. i THE CAVE-DWELLING ANEMONE. 95 contraction and approximation of the column around the retracted base ; and we proved its power of basal adhesion in the specimen which came into my possession ; for it not only attached itself by the entire broad base to the saucer — and that repeatedly after having been removed — ^but during the niarht marched several inches to seek shelter under a O shell. AVhat had appeared to be an epidermis was nothing but a ring of exuviated mucus, which was readily removed, bringing away all the dirt, and leaving a clean smooth Sagartia. The tentacle-feet displayed the B-mark, and there seemed little to distinguish it from the normal colouring, except the dingy drab hue of the column. A specimen of the var. fulvicornis, in my possession, when disturbed, assumed a globular form, with the base contracted to one-sixth of an inch in diameter, and became very buoyant. It thus strongly reminded me of Mr. Holdsworth's sphcero'ides. It seems the habit of the species to be very free ; and this tendency more especially marks the mud-loving kinds with a pale drab exterior. It is a common thing for one of these to lie for weeks in a tank rolling loosely about the bottom, alternately contracting and stretching its column, and folding or expanding its tentacles at pleasure, apparently quite healthy, and yet showing no inclination to choose a settled residence. I have had many examples with this habit, which, by and by, having sown their wild oats, suddenly fix themselves, give up their vagrant ways, and become sober housekeepers. Mr. Holdsworth writes me of one which, after six months' captivity, " has not yet attached itself, but wanders about, like a restless spirit without a home." The suckers are in this species very adhesive ; and in this vagabond condition it is not rare for the Anemone to moor itself temporarily, not by the base, but by these 96 SAGARTIADiE. organs ; sometimes by a few of the most anterior ones, when the "base is thrown up at an angle, in a somewhat undignified fashion. Occasionally I have seen a specimen which had attached itself thus to a stone, or the side of a vessel, and had, by its own weight or other cause, removed a little from its attachment, — still fastened by two or three suckers, which were unnaturally stretched out to a length of the sixth of an inch, and a proportionate tenuity, resem- bling the suckers of a Holothuria, Some observed facts indicate a considerable tenacity of life in this species. On the 5th of October last Iilr. West inclosed in a small tin canister three specimens with a little damp weed, but without water. The box was then addressed to me, and committed on the same day to the post-ofiice at Leeds ,• where, however, owing to the oozing forth of a slight wetness, it was detained. In the course of a few days I informed him that it had not arrived ; but my friend residing out of the town, and my letter arriving on Saturday evening, he was not able to obtain from the over-scrupulous postmaster the suspicious missive, until Monday morning, the 12th — a week (within five hours) of the animals' imprisonment. Of course he expected to find them in a pretty advanced state of decomposition ; but, on removing the lid, saw at once that the case was not hopeless. They were immediately treated to the long- foregone luxury of a bath of sea-water ; and though one of them was hors de combat, the other two recovered, and lived to bear the journey to Devonshire under better auspices. To the same kind friend I owe the possession of the lovely var. lilacina, and the following playful note of its endurings : — " It is one of the French consignment, and has led almost a charmed life. Soon after my letter to you [dated Jan. 27], written after their arrival, I fancied the water in one of the vases was becoming foul, and therefore THE CAVE-DWELLINQ ANEMONE. OT removed all the animals save one — the most valuable, — which could not be found, and which I concluded was the source of the mischief. The vase stood, however, in an empty room tiU, last Tuesday [April 20], — so you may guess the strength of the pickle, — when I emptied out the whole kettle of fish, and found Monsieur at the bottom. He is only the shadow of himself, and looks uncommonly seedy ; but is a character, nevertheless." While writing this article, I have had an opportunity, for the first time, of seeing the discharge of true ova from an Anemone. In a saucer, containing a Corynactis and some varieties of troglodytes, that was standing on my library table, I found, on the morning of the 28th of April, that there had been deposited during the night an even layer of pale brown substance on the bottom, so placed as to make it uncertain whether it had proceeded from the Coi'ynactis or fi-om one of the troglodytes. The mass was about as large as a fourpenny-piece. A little taken up with a pipette, and examined under a power of 500 diam., proved to be composed of ova, opaque, perfectly globular, varying from .0043 to .0051 inch (but the former was an unusually small one) : they were mostly very uniform in size, viz. .0050 inch. They had a clear weU-defined edge, and not the slightest appearance of cilia. I removed the troglodytes to a clean part of the saucer (it was the beautiftd orange var. auricoma), and after a few hours perceived that it was discharging more ova, which were streaming over its lower tentacles, as it lay on its side, but fully expanded. I therefore immediately transferred it to a straight-sided glass box for closer examination. As soon as it had expanded again after the shock of removal, which it did in a few minutes, I began to watch it. It was lying on its side, with its disk and expanded tentacles near the glass side, and facing my eye. Many of H 98 SAGARTIAD^. the tentacles, especially those which were on the in- ferior side, were occupied with more or fewer ova, some having fifty or more, others half-a-dozen, others one or two. In each case they were rolling up the interior of the ten- tacle from the general cavity, and coursing to and fro under the influence of the lining cilia, sometimes accumulating temporarily at the tip, but never, so far as I saw, discharged there. On looking at the mouth, I perceived that the gonidial tubercles of one angle were brought into contact with those of the opposite angle, dividing the mouth into three tem- porary orifices, two lateral and one central. The lateral orifices, however, were at right angles to the ordinary line of extension. Through each of these lateral orifices ova were issuing, somewhat slowly, with an even motion evi- dently ciliary, for the most part not in contact with the sides of the tube, but coming up through its dark centre. As each came into view, and deliberately rolled over the edge of the orifice, it streamed across the disk, and over the face of the expanded tentacles, carried clear of all by means of the ciliary currents of these parts. The ova closely fol- lowed each other, generally in single file ; but occasionally two, or even three, were slightly agglutinated together. Perhaps on an average about three or four in a minute issued, but with many lengthened interruptions of the continuity. The process of egg-discharge did not continue long after I began to watch it ; though the accumulations remained in the tentacles. The next morning, those that had been deposited were for the most part disintegrated, resolving into an undefined mass of minute cells. A few only here and there retained their outline. During the next day or two, especially in the night, a few more were discharged, which were a little larger than the former, averaging .0060 THE CAVE-DWELLING ANEMONE. 99 inch. No result, however, followed the discharge, and they soon decomposed. Dr. Byerly, however, has succeeded in rearing the young of this species ; but from ciliated germs, not from ova. Some specimens which he found numerous on the Leasowe shore of the Mersey, threw off many germs, which could be plainly seen through the skin at the base. These made their exit through " breaches of continuity in the outer envelope near its junction with the basal disk, and some- times through ragged apertures in the base itself." The germs were about as large as a pin's head, perfectly globular, and had a very sluggish motion. Three or four were put into a wide-mouthed bottle and stopped : after two months, one had developed a perfect Actinia, the ten- tacles being fully expanded. At the time of the record it had lived six months ; but having never been fed, it had not visibly grown.* Since the former observations were made, I have proved this species (contrary to what has been asserted of the Actinoids) to be hermaphrodite. The variety in this case was the exquisite one I have named melanoleuca (see PI. V. fig. 5), a large specimen received about a week before from Morecambe. On the 26th of May, this individual, on being put into fresh sea-water, instantly made it turbid. I took it out in the course of the day, and isolated it in a small glass tank of clear water. Presently this also became quite turbid, as if milk had been mixed with it, while clouds of the white fluid were seen floating about the animal. On the vessel being shaken, and again on my touching the Anemone, it contracted ; and, on each occasion, a stream of white fluid, almost as opaque as milk, shot up from the mouth, and slowly diffused itself in the surrounding water. * Edin. New Phil. Joum.; Jan. 1855. H 2 IQO SAGARTIAD^. With a pipette I took up a drop from one of the diffusing clouds, and submitted it to the microscope. It was filled with millions of excessively minute, but vigorously motile atoms, clear and colourless, having an ovate body, and a slender tail, which wriggled their little tails, and rapidly oscillated from side to side, from the tail-tip as a 'point d'appui. This was the first time I had ever seen the sper- matozoa (for such they assuredly were) of the Anemones. The next morning, the water still continuing turbid, I was about to pour it away, when I saw beneath the spot where the Anemone had lain, a thick layer of cream- coloured soft substance, well-defined in its outline. I took up a little of this and examined it. It proved to be a mass of ova. They agreed with those above described, being mostly quite globular (though a few were distorted) ; the majority closely alike in size, viz. .0058 inch ; but a few were manifestly smaller, and measured from .0046 to .0048 inch. They were perfectly defined, with a distinct clear wall, and olive granular contents. When crushed with a graduated pressure to rupture, the whole contents of each ovum were seen to consist of a vitelline mass of minute oil-particles in an albuminous fluid, inclosed in a very thin vitelline membrane. In a few instances I detected the germinal vesicle with its germinal spot, some- times by its clearness when the ovum was flattened, some- times by its escape as a clear bladder from the ruptured membrane : but in many examples I could not find it at all. I removed the Anemone from the vase, leaving the ova alone, in hope that they would develop, but they all decomposed. I may add, that since then I have seen the like discharge of spermatozoa from a specimen of vidnata. I refer with hesitation the Actinia elegans and A. ex- plorator of Sir John Dalyell to this species. The former THE CAVE-DWELLING ANEMONE. 101 he describes as of a reddish-brown or orange hue, with white (snctorial) spots, and well-barred tentacles ; the disk generally crossed with a white line. The latter has more of the ordinary aspect of a troglodytes. Sir John Dalyell observed in the latter (which he named explorator from the circumstance) the occasional elonga- tion of one or two tentacles, which we have seen to be a not uncommon phenomenon in this family. A specimen, not half an inch in diameter, exhibited two tentacles together, each of the length of an inch and three quarters. In general, the elongation took place at night. From its ordinary length of half an inch, each tentacle gradually became two inches long, thickened and distended to transparency. "It is then seen rising from among the rest, curving over to the opposite side of the disk, and as if searching around." After a while, it shrank back to its former state. Both of these (supposed) species were prolific. The latter produced sixty young in one night ; which were pure white, and large in proportion. Of the former, three indi- viduals, in October, produced infusorium-like germs, which were ovoid, and yellow-green in hue : some showed a long transparent horn in front, visible as the animalcule pur- sued a steady course ; behind it was open like a cap. They presented much disparity both in form and size. They swam actively by means of cilia. These germs continued visible throughout October, but, though carefully preserved, they led to no ultimate results.* Since the earlier pages of this article were issued, I have been favoured with an interesting letter from Miss Gloag, of Queensferry, Fifeshire, who has long been a successful cultivator of Anemones. I regret that limited space forbids my giving her communication in extenso : I am compelled * Rem. Anim. of ScotL ; 226, 227. 102 SAGAETIADiE. to select and abridge. This lady finds troglodytes abund- ant on the Fife coast, in several varieties. Of these she specially enumerates lilacina, of which eight specimens have from time to time occurred ; Hesperus, two specimens, and a third well-marked variety. One of the var. Hesperus has been in Miss Gloag's possession fifteen months : " the disk and tentacles are, if possible, whiter than snow ; only at the extreme tip of each tentacle is it quite black. It is a little gem of beauty." This variety frequently elongates two of its tentacles to the length of an inch ; when they lose their opaque white colour, and become transparent, the tip, however, retaining its black hue. The new variety is very showy : it has a bright orange disk, and perfectly black tentacles : thus reversing the colours of EcUpsis. It may be added to the catalogue, as var. <^. Pyromela. Some of my lady-readers may be glad to avail themselves of Miss Gloag's experience in collecting. " I find no diffi- culty in digging the troglodytes out of the rocks or mud. The instruments I use are long, thick hair-pins [of iron- wire, 1^6 th of an inch thick]. I am obliged to have them made for the purpose ; but they are splendid, and seldom fail to bring out the treasure unhurt. After getting my fingers nearly skinned, I bethought me of hair-pins. When I see a troglodytes that I wish to possess, I take one of these strong pins in each hand, and as quickly as I can I put the bent ends down the fissure as -close as I dare to the creature : when I think I have reached its base, I work them gently but firmly towards each other, till I feel I have detached the Anemone, when it is easily lifted out either with the fingers or with the pins." More recently still, Mr. D. Robertson has sent me from Cumbrae an exquisite variety, of which I was at first inclined to make a distinct species. It has the charac- THE CAVE-DWELLING ANEMONE. 103 teristic marks of troglodytes, however, on disk and tentacles. Column marked with longitudinal green bands on a pellucid olive ground. Tentacles very short and conical, pellucid, with three transverse white bars, and three longitudinal streaks of fine grass-green, reaching from the middle to the tip ; one frontal, broad, the others lateral, narrower. Disk pellucid olive, with a white lip. This variety I enumerate as y^. Pra^inopicta. All the varieties of this species are hardy in confinement, and accommodate themselves readily to almost any kind of bottom. Many observations (some of which have been already mentioned) concur in showing its tenacity of life under circumstances, ^uch as long imprisonment in a box, foul water, &c., that would prove fatal to other species. It requires attention, however, in the aquarium, to preserve it in condition. The more beautiftd varieties, at least, speedily degenerate both in size and colour, if they be not frequently and regularly fed. They possess a healthy appetite, and will greedily devour fragments of raw fish or flesh, or of univalve or bivalve mollusca. Perhaps the best food for all Anemones, and one that can generally be com- manded, is the uncooked flesh of the oyster or the mussel. It should be cut into small pieces, and guided gently to the disk or tentacles of the Anemone, when fnlly expanded. If the animal shrink from the food, and contract ; or if it be allowed to lie on the disk ungrasped, it will be of little use to allow it to remain: remove the fragment, and wait a hungrier moment. If the food be gradually sucked in, its remains will be disgorged in the course of a period varying from a few hours to several days. Often it will appear little changed ; but it has performed its part, and must be carefully removed, or its decomposition will be likely to spoil the water, and kill, or at least render sickly, the living tenants. The frag- 104 SAGARTIAD^. merits may be removed by means of a bent spoon at tlie end of a stick, by boxwood pliers sold for the purpose, or by a glass tube closed at one end by the finger.

Margin tentaculate. Disk. Flat; the margin plane. Outline circular. Radii distinct; crossed by fine striae. Tentacles. About two htindred, arranged in five rows ; of which the first and second contain each twelve, the third twenty-four, the fourth forty- eight, the fifth ninety-six. Those of the first row are longest ; but there is not so much difference between the rows in this respect as is the case with the preceding species : those of the first row, when fully extended, are longer than the width of the disk ; all are slender, tapered to a fine point, and very flexuous. They are usually carried either arching downwards on every side or sub-erect, and thrown into many irregular snaky curves. Mouth. Set on a low cone. Lip thin ; slightly furrowed. Acontia. Emitted from variovis parts of the body, from the base to the summit, occasionally ; but very reluctantly, and in small quantity : short and slender. 106 SAGARTIAD^. Colour. Colwnm. Ground tint a ligtt buff, sometimes merging into a warm fawn, or wood-brown, at others into a flesh-bue, or even pale scarlet. This is marked with longitudinal bands of paler hue, sometimes almost white ; the bands being equal to the interspaces. As these bands approach the base they become more defined, and the contrast between the alternate dark and light hues is beautifully distinct, especially as they are separated by slender jagged lines of very dark brown. The whole upper parts are freckled with numerous brown dots; and the suckers are generally inclosed each in a little olive blotch. Bisk. Ground tint a dull whitish-grey, covered with a regular speckled pattern, formed of the following elements. At the point where each tentacle springs from the disk, the radius is marked by a long dash of deep brown, or blackish, at each edge; the intervening space between the dashes is occupied by a transverse band of pellucid greyish-brown ; two other similar bands cross the radius at equal distances, but without the bounding dashes. As the markings of the secondary radii do not coincide in posi- tion with those of the primary, the result is the minutely chequered or dotted pattern above spoken of. Go- nidial radii often opaque white. Tentacles. Translucent grey, marked on each side with a line of dark brown running through the whole length. Occasionally a very faint ring of pel- lucid white surrounds the tentacle near its middle, and a second just above its foot : the lateral lines are lightened at these places, but their continuity is not interrupted. They end abruptly just above the junction with the disk. n-T.-xrrr»r.r,;. Moutk. Grcylsh white ; with darker (right side). furrows. Size. Average specimens in the button state are about five-eighths of an inch in height, and the same in width of column ; the base covering an area of nearly an inch in diameter. Such a specimen in ordinary expansion would spread an inch and a half from tip to tip of the tentacles. But specimens an inch and a quarter in height and width in the button are not rarely met with.

Vambtt. The only distinctly marked variety that I have noticed besides those diversities of the genei-al tint that I include in a. Aleurops,* — the mealy-faced condition above described, — is 0. MeIanops;\ which has a broad well-defined band of deep black, crossing the disk and tentacles ; just as if a dash of ink had been struck across the whole flower ; including in its breadth three or four tentacles of each row on each side. The band crosses at right-angles to the line of the mouth ; the gonidial radii of which are white. Sagartia viduata is somewhat liable to be confounded with troglodytes ; and some varieties of the latter approach it very nearly, especially when closed. But an experienced eye will seldom be deceived ; the tint of viduata is a warmer brown, generally mealy, or speckled ; that of troglodytes tends to drab, smoky brown, or olive, and is not speckled : the stripes of troglodytes, when present, are closer, generally narrower, and rarely extend far from the base ; the suckers, too, which are so obvious and so constantly used in troglo- dytes, are inconspicuous in viduata, and rarely used for attachment. Then, when expanded, the peculiar pattern of each disk respectively does not merge into the other, though in troglodytes it is apt to become evanescent : the tentacles in this latter very rarely show obscure lateral lines; in viduxita these marks are constant and conspicuous: the more slender form of these organs, and their tendency to assume irregular curves, in viduata, are also a very good distinction. I have no hesitation in identifying the species which we get so abundantly in Torbay, and which I have described above, with Mr. Price's anguicoma ; though that gentleman has not noticed the characteristic tentacle-lines.

In the only specimen in which I have had an opportunity of examining the mouth with exactitude, there was only one gonidial groove, with its pair of tubercles.

The name of this genus was assigned to it by the late Edward Forbes in honour of John Adams, who first described the animal as British. It had, however, been described and figured by Bohadsch before him, and by many since, " both at home and abroad," and by no one more accurately than Dr. Coldstream, the principal parts of whose account are cited in Johnston's " British Zoophytes," (Ed. 2, p. 207.) The true character of the animal has been THE CLOAK ANEMONE. 127 pointed out by myself in *' The Aquarium," in which I have thus explained its manner of growth. — '' The Adamsia is evidently an Actinia of a long-oval form, capable of development in its long diameter into two lengthened wings. Its instinct invariably leads it to select as its support the inner lip of some univalve shell ; having ad- hered to which, the lateral expansions creep along the shell, following its surface until they have surrounded the aper- ture, and meet each other on the outer lip. Here the meeting edges unite by mutual adhesion, and seem to grow together ; yet the suture is always distinctly visible, both by a slight depression, and by a pale line which assumes a zigzag form, owing to the terminations of the body-striae fitting into the interspaces' of the opposite ones."* In Plate III. fig. 8, 1 have depicted an individual, adherent to the shell of Buccinum unddtum, in which the lateral lobes, though projected around the edges of the mouth of the shell, have not yet met each other on the outer lip, but are separated by a space of a quarter of an inch. And I have seen a very young specimen, less than half an inch in diameter, the outline of which was exactly like that of a normal Anemone ; the lateral lobes not having yet com- menced their extension. This little individual was adherent to the inner lip of the shell of a Garden Snail {Helix aspersa) , which had been accidentally washed into the sea. A Pagurus Prideauxii had selected the same shell as his abode, and to his wanderings it was probably owing that the shell had found its way into eight fathoms' water, a mile or two from land. This manner of growth is further illustrated by what takes place at the disease and death of the animal. The adhering base begins to peel off, and shrink away from the * Aquarium; Ed. i. p. 139 ; et aeq. 128 SAGARTIADiE. shell. This process invariably hegins at the suture, and as it goes on the suture divides, the lateral portions separating more and more from each other by shrinking ; thus reversing the steps by which the annular habit was assumed. So far as my own experience goes, the Adamsia always selects for its support the inner lip of a turbinate shell. Buccinum undatum I have generally seen chosen at Wey- mouth, but not rarely the various species of Trochus ; and a Helix I have already mentioned : Adams found it at Milford Haven, on Murex despectus (= Fusus anttquus) : Thompson, at Belfast, on Bulla lignaria, as well as on the larger Trochi : E. Forbes, at the Isle of Man, on old Fusi and Trochi: Landsborough, at Arran, on Turritella and Buccinum. Mr. D. Robertson sends me specimens from Cumbrae, on Trochus umbilicatus. I believe that the shell chosen is always tenanted by a Hermit Crab, and that the species is invariably Pagurus Prideauxii. In this my observation coincides with those of Dr. Coldstream, Thompson of Belfast, and Mr. D. Eo- bertson. Forbes seems to throw doubt on the constancy of this association ; having taken many specimens on the Manx coast, the shells of which were not tenanted by any crab. Similar examples have occurred to myself at Weymouth ; but when we remember how readily the Pagurus leaves its shell on alarm, and how terrifying the rough action of the dredge-iron must be, it seems the most obvious mode of accounting for the occasional vacancy of the shell, that it has been just deserted by its frightened tenant. The Adamsia itself in early life has the power of shifting its quarters. Forbes observes that it " seems to change its habitation according to its size : " and I have had two young specimens in my aquarium, which crawled sponta- neously from their shells, and attached themselves the one to a stone, the other to the frond of a sea-weed. While THE CLOAK ANEMONE. 129 writing this article, Mr. D. Robertson sends me accounts of two in his possession, which manifested the same propensity. Each first detached the two lobes from the shell, which then were thickened, and apparently hollow, being much dis- tended with water. The same evening, both began to adhere to the side of the jar in which they were kept, by their lateral lobes. Three days afterwards, the lobes were " still firmly and broadly adhering to the bottom and sides of the jar." Mr. Thompson, of Weymouth, has dredged a specimen, which was adherent to a frond of Fucus serratus. It was round, about as large as a shilling, and flat, but " with the appearance of a suture down one side, as though it had joined." Yery frequently, there is found intervening between the Adanisia and the shell to which it is affixed, a film of membrane, of a homy texture, somewhat brittle, of a translucent dark greenish-brown colour. After death this film is found adherent to the surface of the shell, from which, however, it easily peels when dry. It invariably extends beyond the margin of the lip, making, as it were, an adventitious continuation of the shell, and following the same general spiral direction. From several specimens from the Frith of Clyde, for which I am indebted to the kindness of Mr. D. Robertson, I have been able to learn the nature and object of this membrane. In one of these the shell of Trochus umbilicatiis, full-grown and perfect, had a great continuation of the membrane into a fictitious body-whorl, as voluminous as the whole shell. In another, the shell was that of Buccinum undatum, an inch and a half in height. Here the membrane was confined to a small film, sub-triangular in outline, continuing the front margin of the outer lip, and a similar one continuing the hind margin of the same ; each the production of a lateral lobe of the animal, the two not having as yet attained th« K 130 SAaAETIAD^. point of union. In a third beautiful specimen, sent mc alive, I found, after death, the membrane showing dis- tinct concentric lines of growth. And these took exactly the form of the outer edges of the two lobes, meeting in the centre, where there was a representative suture. The growth-line being curved, there was a delta at the end of the suture ; and this was filled with a much thinner film of membrane, showing that it was the last made. Mr. Walter Gregor, of Macduff, has sent me a large specimen which had in youth chosen a shell of Natica swdida for its support. The shell is in no direction more than one-third of an inch in diameter, but the adventitious body-whorl of membrane measures (along its curve) two inches and three quarters ! From these and other observations of my own, as well as from information supplied by Mr. Robertson, it appears to me manifest that the membrane is a provision for the support of the growing Adamsia, when it has selected small or broken shells. Experiments, which I have detailed at length else- where,* have satisfied me that the membrane is produced by the Adamsia ; that it is an epidermic slough ; and that it is composed mainly of chitine, having no calcareous element. It cannot, therefore, in any respect, be regarded as a corallum. The membrane is not invariably present. In specimens dredged in the Frith of Clyde, small or broken shells appear to be usually chosen ; and these are enlarged, as I have stated above. In Weymouth Bay, however, where the species was common when I was there in 1853, the shell most commonly selected being the Great Whelk, the ' * Annals and Mag. of Nat. Hist, for Aug. 1858. THE CLOAK ANEMONE. 131 membrane is so miusual that I do not remember to have ever seen it. Pagurus Prideauxii s6ems to be as dependent on the Adanma, as the latter is on it. The only instance in which I have heard of its having been ever found disso- ciated from its friend, is the following, communicated to me by Mr. Robertson : — " Lately I dredged a small Pagurus Prid. unassociated ^vith Adamsia palliata. After a few days I put it into a jar with an Adamsia which I have had for some time. I saw them six hom'S after ; Pagurus had left his shell, and was perched on the top of Adamsia^ with his fore claws among the tentacles. Next morning Pagurus was dead, and Adamsia had quitted the hold of his sheU." This association, however, Uke so many other things that the naturalist is constantly meeting with, is unac- countable. Why one species of Soldier-crab must needs seek the companionship of this Anemone, while other Soldier-crabs are able to live alone ; and why this species of Anemone must needs associate with the Soldier-crab- while other kinds of Anemone are solitary, I can by no means answer. Nor is the difficulty in any wise solved by supposing — what we may easily grant — that each may find advantage from the other's presence. Dr. Lands- borough pleasantly says, — " In all likelihood, they in various ways aid each other. The Hermit has strong claws ; and while he is feasting on the prey he has caught, many spare crumbs may fall to the share of his gentle- looking companion. But, soft and gentle-looking though the Anemone be, she has a hundred hands ; and woe to the wandering wight who comes within the reach of one of them, for all the other hands are instantly brought to its aid, and the Hermit may soon find that he is more K 2 132 SAGARTIADiE. than compensated for tlie crumbs that fall from his own booty." It is probable that Adamsia would be a dainty morsel for the table. I have not essayed it, but the smell of the fresh animal is very agreeable, resembling that of the cooked flesh of the crab. Beautiful as it is, it appears unlikely ever to become an habitual tenant of our aquariums, as it cannot long endure captivity. Its crab, too, seems peculiarly unable to survive confinement ; and I do not think the Cloaklet will ever live long dissociated from its companion. Yet Sir John Dalyell seems to have been more suc- cessful than I have been, if I may judge from the expres- sion " a long time " in the following statement. One which had detached itself from its shell " diffused the base on the bottom of a glass vessel, not unlike the wings of a butterfly. But until it adheres, the base remains a long time with its whole under surface merely folded together." He describes it as feeding readily, and as greedy of worms. According to the same observer, thousands of minute, opaque, bright yellow globular germs are produced by the species in July, August, September, and October ; several hundreds being discharged at once ; but no results followed these developments in his experience.* Rapp assigns Adamsia palliata to the Mediterranean and North Seas if MM. Koren and Danielssen mention it as common in fifteen to twenty fathoms off the coast of Norway.! The following list includes its known British habitats : — Wick, Peterhead, C. W. P. : Moray Frith, W.

Diameter of column one-eighth of an inch ; height one-sixth ; expanse of flower one-sixth. Locality. Overhanging rocks and sides of caverns near low-water mark, around Torquay. The large dark overhung pool at Petit Tor, which I have more than once described, is a fertile nursery of marine life. Though situated not much lower than half-tide level, yet, from the volume of water which it contains, the constancy of its fulness, the aspect, excluding the sun's rays, and the inclination of the rocks preventing evaporation, the rough worm-eaten surface, both below and above the brim, is always wet, always dark, and always crowded with Algge, Sponges, Zoophytes, Worms, and Mollusks. This pro- fusion of riches is not always, however, easily available ; for though it stands in tantalising proximity to the eye of the naturalist, it is quite beyond the reach of his hands, unless he choose to wade into the pool and work in the water breast-high. On the 29th of June of the present year I essayed in this manner to rifle the promising treasury ; and the result by no means disappointed my expectations, though, from several circumstances, it was diflScult to work with hammer and chisel. Among other things I obtained there this new form. THE WALLED COEKLET. 137 It has been my custom, — and I recommend the plan to brother and sister naturalists, — not to satisfy myself with such creatures as I see on the spot, but to take specimens of the rock at random for examination at home. I look out for the dirtiest, roughest, most corroded parts of the rock, at the lowest level that I can reach, and with the chisel cut off small fragments. These I bring home, and spread out, face upward, in shallow pans of clean sea- water. After a few hours, say perhaps the following morning, I carefully search with my eye, aided at intervals by a lens, but without disturbing the water, the surfaces of the bits of rock, as well as the sides of the vessel ; and thus I have obtained more than one new species, which I might never have known otherwise. For the actual discovery of the present species, I am indebted to my little son, whose keen and well-practised eye detected the tiny atom, as a form with which he was unacquainted, on one of the fragments I had brought home. Presently afterwards I discerned another specimen; and these two are the only examples that have as yet come under my notice. The rough corky appearance of the epidermis in this and the following species, suggested the generic name, which is formed from ^eXXo?, the cork-tree, and also its bark. The specific appellation indicates the chief distinc- tion between this and the following species, the edge of the epidermis encircling the summit of the animal when con- tracted, as if with a wall. The force of the English appellation is obvious.* * I feel that I am arrived at a point where I need the kind consideration of my readers. Popular as the ciitivation of Zoophytes has become, there are still many who prefer to caU them by English names, the ladies in particular. It is a natural and proper desire, and I wish to respond to it. But no vernacular terms exist, by which the hitherto recondite subjects of thia work are known. What shall I do in this case ? Shall I use the term 138 SAGARTIAD^. In both this and the preceding genus we find a remark- able development of the epidermic layer ; in Adamsia from the base, to enlarge its support, — in FhelUa from the column, to thicken its investing coat. The investment is, as I have intimated, a tightly-adhering epidermic layer, but free at the upper part, which stands up as a thin, clear, firm tube, when the animal retreats. Its substance is strong and tenacious, yet portions of it can be torn away in shreds with a needle. These, under a power of 600 diameters, show, in the clear parts, a structureless membrane, which has a slightly fibrous appearance, apparently only because of its foldings and wrinkles. The greater part is rendered opaque by the foreign matters entangled in it, consisting largely of irre- " Anemone" tlii'oughout, employing an epithet to discriminate the families from each other, a second epithet to discriminate the genera of each family, and a third epithet for each species ? " The Anemone : " " the Warty Anemone :" "the Lined Wai-ty Anemone : " "the Glaucous Lined Warty Anemone." This would be an available mode, but would it not be repulsive and lumbering? Again, I might make new words — arbitrary aggregations of vowels and consonants, — " Fai"Son," " Toler," — words, if words they might be called, without an etymology, and without a meaning. I do not think this would be generally acceptable, though I might plead precedent in scientific technology, — '•' Rocinela," " Conilera," &c. for example. A celebrated Greek orator is said to have coined only three words in the whole course of his professional eloquence ; and, for the comfort of those who should attempt the same again, it is added that the Athenian public refused to swallow these. Yet it is much easier to make a Greek word than an English one, I manufacture " Aiptasia '" and " Bolocera" boldly ; yet it is not without mistrust that I see " Trumplet" and " Opelet" on my pages. In this dilemma, since the words must be made, I have thought that they ought to be formed according to certain conditions. First, they , should be Saxon : " Ilyanth," " Lucemary," " Cyathine," are no more English than if they retained theu' classical terminations. Secondly, they should be significant : the new word should aid the memory, not tax it. Thirdly, they should be consimilar in structure, since they are intended to designate consimilar objects. Fourthly, they should not, if possible, exceed a dissyllabic length. According to these rules, I have ventured to construct a series of verna- cular names for the genei"a. Allowing " Anemone " to stand for Sagartia, I have formed for each of the others a dissyllable, Saxon in origin, sug- gestive of some prominent character, and having a common termination, — viz, the English diminutive " -let," from lie, little. In accoi-dance with this plan. Plumelet may stand as the English representative of ActinoUhci, and Cloaklet of A damsia. THE WALLED CORKLET. 139 gular, clear granules, with some Alga-spores, Diatoms, and here and there a cuida. I removed, with a fine needle's point and pliers, the epidermis piecemeal. It was tongh, allowing the Anemone and its bit of rock (as large as a filbert) to be lifted out of the water by it, without giving way. Its adliesion to the lower part of the column was very firm. As I removed the loose free tubular portion, (the animal having retreated far in at the exirliest assaults,) I discovered free within its cavity about half-a-dozen egg-like germs, of a rich deep orange colour; these, under the microscope, proved to be covered with vibratile cilia, by means of which the germ slowly swam. They were soft, ovate, '04 inch long, by •025 wide. One, on being crushed, was resolved into a mass of minute round clear gi-anules, — fat-corpuscles ? When the whole epiderm was removed, I detached the animal from its adhesion in a small hollow of the lime- stone ; not without the discharge of a thick mucus from the base, and the emission of a single acontium from the lower part of the column. The animal was now reduced to an abject flatness, and looked like a miniature S. vtduata m its greatest contraction. In a day or two it attached itself to the rock again, and even crawled a little way. It now expanded freely, and looked just like an ordinary Sagartia : but did not renew the epidermis.

THE WARTED CORKLET. 141 By a curious coincidence, on the very day that I disco- vered the preceding species, the post brought me a living specimen of the present, from Mr. C. W. Peach, of Wick ; and so the extreme north-east of Scotland and the south- west of England conspired, at the same moment, to augment our native Actinologia, each with a species of a genus entirely new to science. The kindness of Mr. Peach had, it is true, sent me a specimen of the same animal before this, viz. in the preceding May ; but it had arrived dead, and in so advanced a stage of decomposition, that I had not been able even to form a conjecture of its characters. Observation of the species is even now very defective ; for though the last specimen sent arrived in health, and continued for upwards of a month to live in my possession, yet, during the whole of that period, I never saw it expand sufficiently to enable me to describe either its tentacles or disk. For the above description I am largely indebted to the notes and sketches of Mr. Peach. The distinction between PhelUa gausapata and P. muro- cincta is slight ; and future observation may resolve the two species into one. The distance of their respective localities, however, renders their identity less probable. The specimens were obtained from very narrow fissures in a rock called Proudfoot, at the entrance of Wick Bay, in Caithness. This rock is accessible only at the low water of spring-tides. The first specimen obtained, which was much larger than the second, remained unattached for several days, while in Mr. Peach's possession, but appeared healthy. The smaller one sent to me remained adherent to its original fragment of rock for more than a month ; at the end of which time I lifted the base from its attachment. It was in doing this that I saw the acontia copiously discharged from the offended base. 142 SAGAETIADJE. When received, several young algae, — one apparent] j a minute Laminaria, another a Rliodymenia lyalmata, — were growing from the upper margin of the epidermis; a fact which is of value as showing the persistency of this investment, which, moreover, was not separated during the subsequent period of the animal's captivity. The trivial name of this species I have formed from the gaiisajpe, or rough frieze coat which the Roman soldiers wore in cold weather.

Anthea cereus is one of our most abundant species, at least on the south and west coasts of England and Scot- land, and probably all round Ireland. Rapp and Grube indicate it as common in the Mediterranean and Adriatic seas ; but the omission of any allusion to it by Miiller or by Sars implies that it is unknown in the North Sea. Its abundance where it occurs, its habit of congregating in numbers, and its favourite resort, — shallow pools within tide-marks, protected only by a few inches of water from the full glare of the sun, as well as its size and conspicuous colours, — all conspire to make it familiar to the most cur- sory observer. It would, probably, be one of the first species of the whole race to become popularly known ; and hence it is not surprising that old Rondeletius should take notice of it in the middle of the sixteenth century, includ- ing it in his "Libri de Piscibus Marinis," by the descrip- tive epithet of Urtica cinerea.

The species is but little subject to variation of form, or of hue, except within the limits mentioned above. Specimens differ a good deal, how- ever, in the intensity and brilliance of the tints. The Gem was first discovered, or at least distinctly described, just a century ago, by Gaertner, who found it on the shores of Cornwall ; but it was not till fifteen years afterwards that it received a name. Pennant then called it Actinia verrucosa ; but this appellation has yielded to that of A. gemmacea, which was conferred upon it by Ellis and Solander, and which has been so generally adopted by British zoologists, that it would be pedantic to attempt to restore the original name. Both epithets are appropriate. Pennant's (signifying warty) is, however, rather generic than specific; while Ellis's, if somewhat more vague, is well fitted to suggest the delicate beauty of this pretty little species, — perhaps unrivalled, among British species, for its painting. The English term by which I designate the genus, alludes to the pimples^ or warts, with which the animals are studded. It is essentially a littoral species. I am not aware that it has ever been brought up from deep water, nor does it much afiect the concealment of holes or crevices. The surfaces of stones, and shallow pools within tide-marks, are the stations it habitually prefers, and it is often found in the latter even when they are but little below the level of high water. It appears to be gregarious ; for, though we do not find individuals crowded together, as is the habit of hellis, a dozen or twenty are often seen occu- pying the shallow basins of an area of rock a yard or two THE GEM PlilPLET. 192^ in extent, though none are to be seen beyond this. In the button-state, the radiating bands of white on the red- dish-grey ground, with the globular form, give a primdr facie resemblance to an Echinus, denuded of its spines, which is very striking. In their native pools the specimens are often partially enveloped in gravel, from which, if closed, their six-fold star appears prettily conspicuous; while if expanded, the brilliant pencilled disk, and white- spotted tentacles, are even more attractive. The Gem is detached with ease, and becomes reconciled to captivity without difficulty, where it preserves its cha- racteristic habit of stationing itself on some exposed spot, whence it is little given to wander. It is prolific, bringing forth living and well-formed young, which are produced one, two, or three in twenty-four hours, and not scores or hundreds in a night, as are those of S. hellts. The Gem, however, will often continue to breed at this rate for weeks. The new-bom young immediately attach themselves, and display the characteristic colour and markings : they have twelve tentacles ; that is to say, the primary and secondary series are developed before birth. In this condition they greedily devour food when presented. Miss Loddiges, of Hackney, who has been very successful in breeding and preserving this, as well as other species of Anemones, has favoured me with some particulars of her treatment, which may be useful to others. Speaking of the young, this lady observes : — " I feed them from their first appearance, — rather a delicate operation, — and they steadily grow, though rather slowly Oyster seems the best food for them, but I give them lobster, and even meat. ... I am satisfied sea-weed is not necessary in the tank : I have discarded it for some time, and only admit one small piece of red for an ornament. I syringe the water daily." o 194 BUNODID^. The voracity of the species I have already alluded to. From my friend Mr. F. H. West, I learn that it is even ot cannibal propensities. A Sag. troglodytes, var. ^, he suddenly missed, and suspected gemmacea of murder. His suspicions were confirmed, for the lost wretch was disgorged in two portions, of which the first came away on the second day, the second and larger on the fourth. The result of diges- tion was manifest, in the squeezed and shapeless appearance of the masses, the dissolution of the interior, and the flaky sloughing of the exterior. In the published descriptions, often imperfect and vague, of foreign species, we can sometimes find indications of probable affinities. The Act. tuberculosa of Bass's Strait (Quoy et Gaim.), A. hicolor of St. Vincent (Lesueur), A. xanthogrammica of Kamtchatka (Brandt), A. cruentata of Tierra del Fuego (Dana), and A. Macloviana of the Malouines (Lesson), — are doubtless true Bunodes, indi- cated not only by their warty surface, but also by the white spotting of their tentacles. Of these, the first two seem closely allied to our gemmacea, the third to thalUa, while the last two deviate .more from the type, and appear parallel with Ballii. The following are the recognised British localities of the species : — Guernsey, E. W. H. H. : Jersey, G. O. : Weymouth, W. T. (w.) : Torquay, P. H. G.: Paignton, P. H. G. : Falmouth, W. P.

Surface covered with numerous (about thirty -six) vertical rows of sub equal prominent warts, which are separated, in moderate extension, both laterally and vertically, by interspaces of about equal width, in which the skin is irregularly corrugated. The warts are about twenty -five in each row, and reach from the base to the margin, which is serrated with the elongated topmost warts of all the rows. They are strongly adhesive, and are occasionally drawn out to the length of a line, before they yield their hold. Substance firmly fleshy. Disk. Flat, or slightly concave ; radii indistinct. Tentadcs. Sub-marginal, set in four rows; 6, 6, 12, 24^48 : — the first three rows are, however, so nearly equidistant from the centre that, on a cursory inspection, there appear but two rows altogether.

I first discovered this species at Lidstep, on the coast of Pembroke, in 1854, and described and figured it in " Tenby ; a Seaside Holiday." Very little has been added to its recorded history since that time ; not more than four speci- mens having occurred, so far as I am aware, to subsequent researches, all of which were obtained near Ilfracombe. Though manifestly a rare species, I was so fortunate as to light upon a numerous colony at its discovery. About a dozen individuals of different sizes were associated in the dark angles and pools of a little insular rock exposed at spring-tide, that lies just off the cove called the Droch, near Lidstep. They were not troglodyte in habit, but adherent to the open rock, and therefore easily detached. The species seems social ; clustering together in groups, mutually pressing each other's sides. The habits of the Glaucous Piraplet in captivity are THE GLAUCOUS PIMPLET. 197 closely like tliose of the Gem. Like the latter, it expands under the stimulus of the light, rather than in darkness, indicating a habitually exposed mode of life. Like gem- macea, it frequently erects itself •when closed, in the form of a pillar ; and throws off successive rings of mucus from its body, which accumulate around its base, if not removed. The action of the waves would wash these away in a state of freedom ; in a tank they should be detached by means of a stick or hair-pencil. I have never seen the warts of gemmacea used as suckers ; but in specimens of the present species, I observed this function exercised by them very signally ; not in the way of attaching extraneous fragments to the body, like ^S*. hellis and T. crassicomts, but in taking hold of a firm support, like S. troglodytes. The suckers of the column adhered with force to the side of the glass vessel, and by contrac- tion were stretched as above described. The specific name " thallia'' (not Thalia, as M. Milne Edwards misquotes it) I adopted in allusion to the elon- gated form and glaucous colour, from OaWia, an olive- shoot. The same idea recurs in the epithets which distin- guish the varieties, — as if the glaucous, the dull brown, and the chocolate, were the twig as green, dry, and scorched. It is possible that the immature specimens, found by Templeton in Belfast Lough, and named by him Act. mantle,* were the young of this species ; though they have been generally attributed to gemmacea. gemmacea.

Surface covered with warts about equal in size, arranged in forty-eight longitu- dinal rows, of which the alternate rows are traceable from the margin only about half-way down the column ; the warts are contiguous vertically, but the rows are separated laterally, by interspaces of equal width, of corru- gated skin. The primary rows consist of about twenty-four warts, becoming indistinct towards the base; the uppermost individuals of all the rows crowning the margin as blunt teeth. Dish. Flat ; the outline nearly circular, often much overlapping the column. Radii distinct ; gonidial radii broad and strongly marked. Tentacles. Nearly marginal, set in five rows ; 6, 6, 12, 24, 24 := 72 : the first three rows nearly equidistant from the centre. They are longer and more slender than in gemmacea, conical, obtuse ; decreasing in size from the first row outwards ; and are usually carried horizontally spread, with a very constant tendency to curl upward at the tips. Mouth. Raised on a cone ; often gaping ; throat membranous, protru- sile : gonidial tubercles usually prominent, often inflated. Colour. Base. Red, sometimes rich crimson. THE EED-SPECKED PIMPLET. 199 Column. Pale yellow : each wart crowned with a well-defined crimson speck, the interspaces irregularly freckled with crimson.

Ordinary specimens are an inch in diameter and half an inch in height, with an expanse of two inches. Mr. Tugwell figures one two inches in diameter, and three in expanse ; and Mr. Brodrick writes me that one, which has been in his possession nearly three years, measures, after feeding, four inches in expanse.

Cocks had abready described and figured, under the title of ^. BaU{i,t]xe same 200 BUNODID^. species, in his admirable memoir " On the Actiniss of Falmouth," which was read before the Cornwall Pol jtechnic Society, in the autumn of the same year. lie had been acquainted with the species ever since 1847 ; and had pub- lished the name in the Society's Report for 1849. To Mr. Cocks's appellation, therefore, belongs the claim of priority; but even were it otherwise, Mr. Thompson's name must be rejected, not only because it had been previously* applied to another species, but, according to a canon which I have already had occasion to apply to one of my own names,t hecause it conveys a false idea. The name clavata origi- nated in a misconception. In the single specimen known to Mr. Thompson at that time, he mistook the curling of the tips of the tentacles for a cluhhing^ whence the name " clavata " — clubbed. These organs have not the slightest tendency to such a form as the term implies. The name which I adopt was given, I believe, in honour of the late Robert Ball, LL.D., an eminent marine zoologist. I found the species not uncommon at Weymouth in 1853, especially on the ledges that are exposed at the recess of the tide, under Byng Cliff. Its habit is to lurk in narrow fissures in the cavities of the under side of large flat stones, and not unfrequently in the deserted holes of Pholas or Saxicava. The disk is very wide and flat ; and, as it is also very expansile, it spreads itself to a consider- able distance around the margin of its hole. So essential is it to its comfort, however, that it should have a retirement, that if it be put into an aquarium, though it may at first affix itself to a flat stone or to the surface of a shell, it will creep away, by means of its base, till it find some loose stone, under which it will insinuate itself till it is quite * M. Rathke had named clavata an Actinia, which he found on the coast of Norway, in 1843. t See ante, p. 76. THE BED-SPECKED PIMPLET. 201 concealed ; or a narrow crevice, as l)etween two contiguous stones, into which it may thrust its body. The variety h'vida, which is not rare in Weymoutli Bay, in deep water, manifests the same habit, for it is usually found to have ensconced itself in one of the angular cells or cham- bers formed by the coral-like plates of Eschara foliacea^ which afford retreat to so many and so various creatures. A remarkable peculiarity of this species is the degree to which it becomes transparent by distension with water. The effect of this is not the general swelling of the body, as in T. crassicornis, which is remarkable for the same habit effected in another way, but a great dilatation of the disk and tentacles, which then expand to an extraordinary degree, becoming so diaphanous as to be almost destitute of colour, and showing with absolute clearness the craspeda in the intersepts of the visceral cavity. The species is hardy in captivity, and the varieties a and /9 are very beautiful, especially the former. The variety 7 has not unfrequently beguiled me, on a hasty examination, into the notion that S. hellis was before me ; and I tliink that these two species form links by which the families Bunodidce and Sagartiadce are connected. There is also a remote aflSnity between this species and Aipt. Couchii. My friend, Mr. F. H. West, has received B. Ballii from the French coast of the Channel. On our own side it ranges in tolerable abundance from the Hampshire coast to the Lizard, as the following list will indicate : — Selsey ; Ventnor, G. G. : Freshwater Bay, F. N.

The bars of the tentacles obsolete. This fine species first occurred to myself when dredging off Berry Head, in about twenty fathoms, in August, 1858. Three or four specimens came up in about the same number of hauls. In eveiy case the animal was adherent to the shell of the living Turritella terehra, a moUusk which is so abundant there that the dredge comes up half- filled with it. The base of the Bunodes clasps the long turreted shell, nearly enveloping it when adult, only the apex and the mouth of the shell being exposed. Other specimens have occurred since in similar circum- stances ; and Mr. Densham, a collector of Torquay, informs me that in October he obtained a group of eight or ten adhering to a mass of oysters. 204 BUNODID^. It is manifest that this species departs considerably from the type of Bunodes. The irregularity of the warting, the conical form of the tentacles, and their style of colouring, in alternate undefined rings, and the occasional eversion of the walls of the throat, indicate a sensible approach to the following genus. It is always to aberrant species that we look for cross affinities ; and therefore I was more gratified than surprised to see in this animal evident marks of connexion, both in appearance and habit, with the Bagartiadm. Before I had seen it expand, I suspected it to be 8. 'parasitica, especially when in the act of unfolding. It has much resemblance to that species, as well as to 8. coccinea, with which it was associated ; for a number of this little species occurred in the same dredge-hauls ; these also adherent to the shells of the Turritellce. The whole aspect of the Diadem Pimplet, including the colouring, is that of a Sagartia, though the preponderance of its characters deter- mines it to Bunodes. It is interesting, in this relation, to notice, that one specimen in my possession protruded from the mouth a bundle of what appeared to be true acontia. The species lives well in a tank ; where it readily deserts its shell, and attaches itself to stones, or the vessel. It is lively, opening freely, frequently constricting its column, and changing its form with considerable rapidity; its vivacity and brilliant colour render it an acquisition to the aquarium. Both the scientific and the English appellations by which I distinguish the species, allude to the coronet of purple spots which surround the margin. Berry Head, P. H. G.: Torbay, E. W. H.

The name by wliich I have distinguished this genus is given as a tribute to the skill and acumen of Mr. Thomas Pridgin Teale, of Leeds, who published an elaborate and excellent Memoir on the anatomy of the following species. The English appellation is sufficiently obvious. The specific term digitata, " fingered," doubtless alludes to the thick conical form and dull reddish hue of the tentacles, in which the Danish zoologist saw a resemblance to fingers, — those of a ploughman or a scullery-maid, surely ! I distinguish this species from crassicorm's on the autho- rity of Mr. Joshua Alder, of Newcastle, who first mentioned it as British, in his Catalogue of the Zoophytes of that coast. The same gentleman has kindly favoured me with several drawings of the species, executed with his well- known beauty and precision (one of which is reproduced in my Plate), as well as with his MS. notes, from aU of which combined I have compiled the foregoing diagnosis. Mr. Alder entertains no doubt of its specific distinctness ; and his numerous opportunities of seeing it alive and comparing it with the more common kind, render his opinion valuable. He says, " It is the most coriaceous and warty species that I am acquainted with." And again, " It is always much smaller than crassicorm's, more tough and coriaceous, with larger warts, and constantly of a pale red colour." " It is not uncommon," adds the same excellent natu- ralist, " in deep water on our coast ; and as the cod-fishing boats are coming into port frequently at this season [April], 208 BUNODIDiE. I may be able to get you a specimen, though not in a lively condition." Among the numerous drawings of Actinoids for which I am indebted to Mr. W. P. Cocks, there are two which he has not named, but which are evidently identical with the Northumbrian species. Thus I am able to assign it to the Cornish coast. These are the only British localities I yet know for it. DIGITATA. crassicornis. ASTILSACEA. BirXODWJ-. THE DAHLIA WARTLET. Tealta cras»icomis. Specific Character. generally banded- Plate IV, Fig. 1.

In general not much exceeding the column. Column. Rarely pillar-like. In expansion, the diameter greatly ex- ceeding the height. Surface covered with small hollow adhesive wart"", P 210 BUNODID^. Bometimea having a tendency to run in longitudinal lines, but more generally irregularly scattered, leaving intervals of three or four times their diameter in ordinary states of distension, and these intervals have often a silky lustre. Substance firm and even cartilaginous. Margin entire, but roughened with the scattered warts, forming a thick parapet, separated from the tentacles by a broad fosse. In freedom, the column is generally more or less disguised by fragments of stone and shell adhering to the suckers. Bisk. Flat, circular in outline, plane but overarching. Radii con- spicuous chiefly by colour. Tentacles, Arranged in five rows, the first set at about half radius, — 5, 5, 10, 20, 40 = 80; the first and second so nearly equidistant from the centre as to seem but one. Their form is conical, thick at the foot, regularly tapering to a point, which is sometimes slightly inflated. The animals appear to have the power of changing the shape of these organs at will ; for I have had individuals, in which the tentacles, after having for a while borne the ordinaiy conical form, suddenly became nearly cylin- drical, with truncate extremities, and maintained this form for a long time. These organs are nearly equal among themselves, and their length is about equal to one-third of the diameter of the disk. They are capable of little flexure, and are generally spread in a regular star-like manner, the outer rows deflected, the inner erect, and the intermediate ones horizontal. They are powerfully adhesive. Mouth, Frequently elevated on an eminence of varying form and dimensions. Throat and stomach often protruded to such an extent as to conceal the whole disk. Gonidial tubercles two pairs, small. Colour. Column, Dull green, streaked and flaked with crimson, with pale grey warts. Dish, Glaucous-olive, with conspicuous radial bands proceeding from each outer tentacle, in pairs, which curve around the foot of each tentacle of the higher rows, and are lost at varying distances from the centre ; those pairs which enclose the inner tentacles extend farthest and are most conspicuous. The colour of these bands is scarlet, often edged with white, and they are highly characteristic of the species. Tentacles. Pellucid light brown, with a band of opaque white across the foot, which frequently stretches a little way up each side : a broad band of crimson surrounds the middle, bounded below, and sometimes above, by a narrower band of sub-opaque white. All these bands are undefined, and are often rendered sub-pellucid by* distension. Mouth. Generally tinged with crimson. Gonidial tubercles crimson. Throat and stomach light grey.

In my " Devonshire Coast " (p. 36), I stated, with the reasons which led me to it, mj firm conviction that what had hitherto been considered as two species, under the names of A. crassi'comis and A. cortacea, were one and the same. Seven years' additional experience has only added to the strength of that conviction, and I have not been able to find a single stable character on which their separation could be grounded. It is equally clear which of the two specific names must stand. Rejecting Linnaeus's as out of the question, we find that crass icornis was applied to the species by Miiller, twenty-one years before Cuvier called it coriacea. With regard to significance, both appellations are good, perhaps equally good ; the former indicating the P 2 212 BUKODID^. thick horn-like form of the tentacles, the latter the tough and leathery consistence of the flesh. The law of priority, however, must be obeyed. Scarcely less abundant than Act. mesembryantJiemum, this magnificent species is sown broadcast upon all our shores, and seems everywhere to be equally common. In its habits, however, it is widely different from that favour- courting species. Somebody has illustrated the character of two peoples by saying, that if an Englishman retires from business and builds a box, he raises a high wall, and plants a shrubbery before it, to keep off the eye of the profanum vulgus ; but a Frenchman under similar cir- cumstances builds his house on the very edge of the high- . way, and takes his meals in the verandah. If this be true, the Actinia is a Frenchman, the Tealia an Englishman. You may hunt among the rocks till the rising tide covers them, and, finding hundreds of Beadlets, but not a single Dahlia, go away with the conviction, that the latter is a scarce species ; but to-morrow, an initiated friend accom- panies you to the same spot, and, pointing with his toe to an angle, says, " Here they are! and here! and here! — three, four, half-a-dozen in a group !" and you are tired of collecting before the profusion fails. It is in the angles formed by some great boulder with the beach, that the crassicornis delights to dwell ; and here, according to his recluse habits, he chooses to conceal his showy person from intruding eyes, by covering himself with a coat of gravel and fragments of shell, which he has attached to his adhesive suckers, till only the experienced eye can detect the difference between the animal and the surrounding rubbish. Not seldom, however, do we meet with a colony in some persistent rock-pool, in whose never-ebbing fulness the gorgeous creatures remain almost permanently ex- THE DAHLIA WARTLET. 213 panded, despising, or not needing, the precaution of con- cealment practised by their tide-deserted brethren of the beach. It is a remarkable example of the economy of creation, that these tide-pool specimens, as well as those which are brought up from deep water, rarely, if ever, indue their bodies with an extraneous covering. In such pools crassicomis makes a noble appearance. His great size, the wide expanse of the flower, the thick tentacles so symmetrically disposed, and the rich hues often finely contrasted, — make it by far the most showy of our native species. By some of our fair collectors it has been named the Dahlia; a comparison which the size, symmetry, and varying hues of that favourite flower render not inapt. I have accordingly adopted it ; designating the preceding orange-hued species by the appellation of the. Marigold. The resemblance has been acknowledged by one more conversant with flowers than even the ladies. "On one occasion," observes Mr. Jonathan Couch,* " while watching a specimen that was covered merely by a rim of water, a Bee, wandering near, darted through the water to the mouth of the animal, evidently mistaking the creature for- a flower ; and though it struggled a great deal to get free, was retained till it was drowned, and was then swallowed." Mr. E. L. Williams, who has enjoyed unusual opportu- nities of acquaintance with the deep sea, writes me con- cerning this species as follows : — " When diving in bells at Dover, at the Admiralty Pier, in eight to ten fathoms^ water, I have often seen it, generally on the tops or sides of lumps of rock. The -^sop Prawn [Pandalus annuli- cornis f] was very common there, and seemed its food. I never saw a closed crassicomis in deep water, except while catching its prey." * In Johnston's Brit. Zooph. i. 225 ; et in litt. prir. 214 BUNODIDiE. My esteemed friend, Professor E. P. Wright, of Dublin, hai favoured me with one of his vivid pictures, in which this species forms a prominent feature. It will be read with interest : — *' There is a very fine cave here, [Crookhaven, county Cork,] entered at either high or low water by a boat, whose entrance is guarded on both sides by a long low reef of rocks, and of a depth at low water of about ten or twelve feet. The sea-floor is shaped somewhat like a Spanish hulk, i.e. rather flat at the bottom, and then rising up gradually and * wideningly ' to a distance far above our heads, and then ending in an arch formed of sharp-pointed icicles of the by-me-never-to-be-forgotten Devonian slates. To this cave all the fat and fair anemones of the county seem to be sent, when once they have reached a good bodily condition. The cavern is of ample dimensions, so they don't crush each other for room ; and the regular manner in which they dispose of themselves is worthy of note. Actinia mesem- hryanthemum — the green, scarlet, and strawbeny varieties — occupied the highest row, some of them partly out of the water; they had eyes, and kept a 'look-out' for the rest. Then came Sag. venusta and Sag. nivea, lovingly inter- mixed, and in a large broad band some four feet deep. Then there came an empty row of benches, necessary to keep the tenants of the galleries from the aldermen in the pit, for it was filled with T. crassicornis. 1 verily believe the biggest of the big were here ; and the commonest variety was the one with the white tentacles and red disk — a splendid show for size of specimens and magnificence of colour. This cave of Anemones never can be surpassed, and seldom will the wild gi-andeur of the cliffs, a hundred feet and more high, with the Atlantic waves rolling in to fill up the picture, — be equalled." The voracity of this fine creature is remarkable. The THE DAHLIA WARTLET. 216 Shore-crab [Carcmus] is its ordinary prey, but it feeds on limpets, and other Mollusca. Dr. Johnston tells of one , that had swallowed a valve of the Great Scallop, and of the strange result;* Dr. E. P. Wright had one which discharged as the remains of his evening's meal, " a mode- rate sized Fusus, and a mass of Nereids and Shrimps, that exhaled such a fearful smell as killed all mj tank-full;" and one in Mr. F. H. West's possession actually made a honne houche of an Echinus miltaris, as large as a shilling, making no bones of the spines. Two days afterwards the shell of the Urchin was disgorged, perfectly empty, denuded of its spines, the oral plates crushed in, and partly ■wanting. The common Blenny and other fishes frequently fall victims to the rapacity of this gourmand, which spares not its own kindred. The tentacles are very adhesive, as is sufficiently mani- fest to our fingers, when we touch them ; and contact with these organs is amply sufficient to resist the most vigorous attempts to escape of the animals above-mentioned. Beautiful as is the Dahlia, it is not a very frequent tenant of our aquariums ; as it is one of the most difficult to keep. I have, however, kept specimens for four and five months ; and Mr. West still longer ; for the epicure whose urchin-diet is recorded above, had been then nine months in captivity. It appears to be little able to sustain extremes of temperature. The heat of summer is generally fatal to our captive specimens ; and a severe winter makes havoc among those which are in the enjoyment of freedom. After the intense and protracted frost of February, 1855, the shores of South Devon were strewn with dead and dying Anemones, principally of this species, which were rolled helplessly on the beach, their bodies almost concealed by the protruding craspeda. This symptom is almost the * Brit. Zooph. L 235. I 216 BUNODIDiE. invariable accompaniment of disease and death in crassi- cornis ; these organs are present in unusual profusion, and are forced out at ruptures of the integument, bj the con- tractions of the animal. The mesenteric membrane by which they are united to the septa is capable of great expansion: Sir John Dalyell has seen it protruded and spread up the side of a glass vessel, to the breadth of an inch. I have seen a similar phenomenon, but not quite to the same extent, in Peachia hastata. As in the case of A. mesembryanthemum, the ubiquity of this species renders a catalogue of its localities unnecessary: it is distributed everywhere on the British coasts. Of foreign species, so far as may be conjectured from published figures and descriptions (often imperfect), the following may belong to this genus : Artemisia (Dana) from N. W. America ; pluvia (Dana) from Peru ; gemma (Dana) from Cape Verd Isles ; papillosa and ocellata (Lesson) both from Peru; ajid fusco-rubra (Quoy et Gaim.) from the Tonga Isles. Of these the first-named seems intermediate between the present species and B. thallia. B. thallia. [Artemisia]. CRASSICORNIS. H. Margaritas, St. Churchige. Sagartia. Anthea. Bolocera. [Phymactis].

He has favoured me with a spirited drawing of it, but I cannot satisfy myself that it is anything more than T. crassicornis. Tealia tubercttlata (Cocks). In the Report of the Comwali Polytechnic Society for 1851, Mr. W. P. Cocks has described and figured a species, which he names Actinia tuberculata. " Body globular, light- brown, densely covered with large greyish-white tubercles, the apex of each tubercle depressed; disk white; mouth large ; lips thick, corrugated, and everted ; tentacula nume- rous, large, obtuse, some bifurcated, others trifurcated. Diameter three and a half inches when contracted." By private communication I learn further particulars. It was obtained thirteen miles south-west from Falmouth, attached to a valve of Pecten maximus ; it lived with 3Ir. Cocks for some months. " Bulky, rather loose in texture, when ftdly expanded covering the bottom of a large pan, — it had the appearance of a mammoth hellis. It appeared to be ex- tremely irritable, and upon the slightest provocation would throw oflF from its body a large quantity of thick glaire, which, if allowed to remain, produced a disagreeable smell. When contracted it had the appearance of a half-boiled sago pudding." I ventured to suggest that it might have been a great colourless deep-water specimen of crassicornis ; but Mr. Cocks repudiates the identification, while he admits the relationship. The tendency of the tentacles to a monstrous fission seems to me its most marked peculiarity. It may be distinct. 218 GENUS IV. HORMATHIA (Gosse). Base adherent ; greatly expanded.

Walter Gregor, who obtained it in October last, from the lines of a deep-sea fishing-boat, and forwarded it to me. It was dead, however, when it reached me ; but his own careful notes and sketches, made while it was alive, have enabled me, in combination with my own imperfect observations, to characterize it as above. As he had never seen another specimen, I can add no more parti- culars of its history. The name of the genus I have formed from opfiado^;, a necklace of pearls, and the English appellation perpetuates the same allusion. The specific name is given at the discoverer's request, in honour of a lady, one of his most esteemed friends. The unsullied pearly whiteness of the animal, as well as its necklace, gives a peculiar propriety to this name, — margarita signifying a pearl. The genus is aberrant in this family; the paucity of warts, and the soft and thin texture of the skin, departing manifestly from the typical forms. It approaches the Sagartiadoe through Adamsia ^alliata and Sagartia para- sitica, with both of which it has obvious relations. T. crassicornis. Margarita. Sag. parasitica. St. Churchise.

In the month of January, 1857, I was favoured with a communication from Miss Church of Glasgow, containing descriptions and figures of this showy and undescribed species, a specimen of Avhich she had procured in Loch Long, in the previous summer. It had been brought up in the meshes of a turbot net. Its brilliant hues, and their flaked arrangement, the protean variability of its shape, and its vivacity, attracted her notice, as did also the fact that it discharged a multitude of globular ova, of the size of mustard-seed, and of a rich scarlet hue. 224 BUNODIDiE. Last May, Mr. C. W. Peach, of Wick, sent me numerous sketches, some of which were coloured, of an Anemone which he had obtained at Peterhead, in April, 1850, and again in December, 1851 ; on each occasion from the hook of a fisherman's deep-sea line. These were manifestly- identical with Miss Church's specimen. It was not, however, until October, 1858, that I became, through the kind zeal of the Rev. W. Gregor, of Macdufi", personally acquainted with this fine species. Within three months he has sent me, on difierent occasions, half-a-dozen individuals, including all the varieties distinguished above, wliich argues its variability of character. This gentleman has been familiar with it for several years, as a not un- common inhabitant of the deep water of the Moray Frith. It is observable that all the specimens on record have been obtained by means of the deep-sea fishing boats. The generic name I have formed from <7T6fJb^or}, form. The English term commemorates * Annales des Sci. Nat. 1842, Ser. 2, xviii. 65. THE PAINTED PUPFLET. 257 the habit of the genus, of puffing out the bladder-like termination of the column. The habit of the species, judging from what I have seen of it in captivity, is to burrow in fine gravel or sand at such a depth as allows it to protrude the coloured capitulum. from the surface. Here it expands its tentacled disk for passing prey : I fed it with fragments of a shrimp, and found that it ate with the same avidity, and in exactly the same manner, as its cousins, the Sea- Anemones ; the tentacles catching and moving to and fro the morsel, and disposing its position and direction so as to faciKtate the mouth's grasping it ; this latter organ expanding its flexible lips to an apparently indefinite width, and gradually en- veloping the presented food. If rudely touched, the disk was suddenly withdrawn ; the capitulum, and then the upper two-thirds of the scapus, disappearing in rapid succession by a process of intro- version, exactly like that by which the earthworm with- draws its fore parts, or, to use a homely simile, like the turning of a stocking. The extent to which the intro- version proceeds depends on the degree of annoyance to which the animal has been subjected, or on its wayward will. It is capable of crawling along in its subterraneous abode, while contracted ; pushing aside the gravel with the front of its body. It proceeded in this way two or three inches in as many hours, while I was watching it, before it turned upwards and thrust out its head ; the evolution of the capitulum not beginning until the surface was reached. A second specimen of this species was dredged by the Rev. Charles Kingsley, off Brixham, in January, 1854. He informed me that the form and colours agreed with my description, except that the hues of the capitulum. were more brilliant, and those of the disk less so. " He broke off his tail in disgust two days ago, but has now thought S 258 ILYANTHID^. better of it, and has begun wisely to grow a new tail, wliicli is at present transparent, hut with a well-defined orifice. He lies lialf-buried in sand, and lias several times temporarily attached himself by his new tail."* Since this page was in type, Dr. Hilton has taken a specimen at Bordeaux Harbour, Guernsey, which he has kindly transmitted to me. In its general characters and markings, it agrees with the specimen described above ; it is, however, much larger, being at least five inches long, and three-eighths in diameter. The scapus is more spindle- shaped, and more coarsely invected and corrugated ; the physa I have seen inflated, but slightly. The tentacles which correspond to the gonidial radii, and the pair at right angles to these, are much shorter than the rest. The dark gonidial radii have a flush of rich green. ]\Iany points in the form and anatomy of this genus indicate, as has been ably shown by Quatrefages, a decided approach to the EcMnodermata, through such forms as Syrinx and Svpunculus.

Locality. The south-western coasts of England ; eroded rocks. This beautiful and interesting little species was first made known by myself in the Annals of Nat. Hist, for September, 1856, from a specimen kindly forwarded to me by Miss Pinchard, who obtained it from the rocky islet called the Orestone, ofi* Torquay. In May, 1858, three specimens were forwarded to me by my friend, Mr. F. D. Dyster, out of some hundred and fifty that were found by a collector on rocks, between tide- marks, near Tenby ; and a few weeks after this I was so fortunate as to discover a populous home of the species, in the neighbourhood of Torquay. On the south side of the promontory, called Petit Tor, on the coast of South Devon, there is a low-roofed cavern, whose orifice is left bare at the lowest water of spring-tides. The interior parts of the floor are covered with the common limestone shingle, and, being more elevated than the mouth, afibrd an opportunity of working within, whenever one can gain admittance. The roof and sides of this cave are studded with the pretty little Crimson Pufflet, as well as with many other Anemones. The tide having receded, they are very readily discovered by their crimson columns projecting an eighth of an inch from the dark floccose rock, ti The limestone is much eroded by Saxicavce; and it is in the old burrows of these Mollusca that the Edwardsia THE CRIMSON PUFFLET. 261 dwells, clmging to the sides or bottom of the hole by the suckers on its- skin, the column and disk now protruding, where formerly the siphons of the Mollusk projected. It has forcibly reminded me of Ossian's beautiful image of the fox looking out of the window in the desolate dwelling of Moiua. In captivity the animal is able to roam about the glass by means of its adhesive suckers. Under high magnification the epidermis is seen to be a film of condensed mucus, evidently composed of disin- tegrated cells, in which are entangled a few cnidce, some threads and many spores of Confervce, and multitudes of Diatomacece, of many species. I carefully removed piece- meal the whole epidermis from one, exposing the skin of the entire scapus, which then was seen to be fleshy, pel- lucid, pink, and in all respects like that of the terminal regions, except that it was slightly more dense. In a few days the scapus was again encased in an epidermic tube, thin and semi-transparent, but, instead of being yellowish or brown, it was quite grass-green. This I found to be owing to the entanglement of conferva-spores in the mucus, the water having been exposed for some days in a shallow saucer. After having been kept some days in stale water, the animal is found much contracted and retired to the middle part of the epidermic case. This may be then readily removed, the adhesion having ceased. The organic con- nexion between the epidermis and the scapus thus appears to be less in this species than in others of the genus, and approximates it to Phellia in the Sagartiadce. This pretty Pufflet is easily kept in the aquarium, but it appears to require a considerable volume of water in a state of purity. It sometimes floats at the surface, extended at foil length. It will feed readily on minute atoms of raw 262 ILYANTHID^. meat, like the common Anemones. All its movements are rapid, sudden, and spasmodic. Torquay, P. H. Q. : Tenby, F. D. Dyster.

About the same time that Mr. Kingsley dredged E. cal- limorpha at Brixham, he found at Torquay, washed up after an easterly gale, an individual of the same genus, but manifestly distinct in species. While generally agreeing with E. callimorpha^ in size and form, it differed in tlie following points: — 1. The scapus was less opaque, more smooth and lubricous, and studded with longitudinal rows of minute warts between the invections. 2. The capituh/m was clavate, proportionally longer, and of the same colour as the scapus, a pale pinkish-buff, or light orange. 3. The tentacles were fourteen in number, slightly uncinate or incurved, banded with dark buff. 4. The disk was trans- parent and colourless, with a dark protruded mouth. From these characters I think it probable that the animal in question was referrible to the E. Beautempsii of M. de Quatrefages. 263 GENUS V. ARACHNACTIS (Sars).

This very interesting form, the only British example of a natatory Anemone, lias occurred on two occasions, both in the month of August, and both in the Minch, the strait that divides the Isle of Lewis from Scotland : — first by Dr. Balfour in 1841, who obtained a number of specimens, but all in a mutilated condition, and subsequently by Messrs. E. Forbes and Goodsir in 1850. In the interim, the Rev. Mr. Sars, of Bergen, had described and figured it in an elaborate memoir in the '' Fauna Littoralis Xorvegiae " (1846) ; and it is from this that we derive our chief know- ledge of the species, Forbes's account being exceedingly meagre. It appears in the vicinity of the Isle of Iloroe, on the coast of Norway, in autumn and winter, swimming on the smooth sea, sometimes in dense shoals, sometimes singly, borne on the northward current. Comparing the periods of its occurrence in the Hebridean and Norwegian seas, we may infer that it comes up from the warmer parts of the Atlantic ; and it might be hopefully looked for on the west coasts of Ireland in the earlier summer. As it swims it carries the marginal tentacles horizontally spread, when it looks not unlike a long-legged spider: hence the generic name from apd^(yrj, a spider, and uktUj a ray, and hence also the English term I have assigned to it. The superior or the inferior extremity is indifi*erently carried uppermost. It swims by a languid undulation of the long 266 ILYANTHID^. tentacles ; but it has a certain power of crawling also ; for these organs are strongly adhesive throughout, and the animal, attaching itself bj these means to foreign bodies, slowly draws itself forward. The gular tentacles are usually projected, and clasped together, but sometimes they are horizontally spread. In the latter case, if touched, they are instantly drawn to- gether, and slightly contracted, but never retracted ; they have no adhesive power. The appearance and situation of these organs have suggested to my mind the thought that possibly they may be the lobes of a conchula, in which case the animal would be a swimming PeacJda: if, however, they are true gular tentacles, then the alliance is obvious with the following genus Cerianthus. May it not possibly be the immature condition of this latter?* There are discrepancies in form and colour, and especially in size, between the specimens seen on our own coast, and those described by Mr. Sars, which make it possible that these may constitute two species. We trust other speci- mens may clear up . this and other questions of interest. Forbes found a species of the same genus abundant in the Grecian Seas, but whether identical with this, we are not informed. The internal structure, which, from the transparency of the integuments is clearly seen, presents nothing peculiar. ? Peachia. AcALEPHA. ALBiDA. Anthea. ? Cerianthus. * See M.

Greatly lengtbened, cylindrical for the most part, but gene- rally swollen at the inferior end into an elliptical bulb, and gradually expanding into a trumpet-shaped summit to about twice the median diameter. No distinct margin, the summit of the column itself dividing into the tentacles, the ridges of which are apparent for some distance below the point where they separate. Inferior extremity pierced with a round orifice, which is placed at one side of the axial line. Mesenteric prolongations of the visceral septa twenty-four, of which one pair are very minute, while the opposite pair extend to the immediate vicinity of the inferior orifice. From the one to the other of these conditions there is a regular gradation in length, but from the longest to the middle pair the diminution is slight, while from the middle pair to the shortest it is great and rapid. Dish A deep funnel-shaped cavity, about twice as wide as the column, entire, circular, not overarching. Tentacles. Of two kinds. First series strictly marginal, sixty -four, set in two rows, alternating, but with their bases in mutual cbntact. They are equal, slender, conical, sharp-pointed, divided more or less conspicu- ously into knobs, by some half-dozen constrictions. Their contour is some- what stiff, and they are generally carried arching upward and outward ; but some of the inner row are frequently erect, and others inclined to a point over the disk. Second series remote from the first, crowded, in four irregular circles, springing immediately around the mouth ; filiform, obtuse, sub-equal, not half as long or thick as those of the first series. THE VESTLET. 269 Mouth, A. tranBveree slit ; lip minutely furrowed, not projecting. Investing Tube. Cylindrical, much wider than the animal, which is loosely invested by it without attachment in any part, papery or felty in texture, thick and soft, composed of many layers, the outer of which pre- sent ragged foliations. The tube can easily be detached, when the ani- mal immediately begins to form a new one, by throwing off the material from the entire surface of the column ; this at first is adhesive, tena- cious, and very tough, pellucid, but gradually becomes milky, and finally opaque, entangling mud and sand in its substance- It is wholly composed of cnidcE, the discharged ecthorcea of which, in in- calculable numbers and of great length, inter- twine and form a sort of felt. Colour. Column. Pale buff or whitish, gradually becom- ing rich chestnut brown at the summit. Disk. Pellucid white. Tentacles. First series maronne or chocolate-brown at the foot, above which pellucid whitish, with chestnut bands. Second series dark maronne. CEmXSTSTJB mthout its tube. Size. Length seven inches, under strong irritation contracting to two ; general diameter of column one-fourth of an inch ; of disk half an inch ; expanse of flower one inch and a half. 270 ^LYANTHID^. Locality. The Menai Strait, in North Wales, and the Channel Islands ; between tide-marks. Varieties. Specimens differ considerably in the depth and extent of the brown tints of the upper parts. In some the maronne or red-bi"own hue extends across the disk; in others it is scarcely discernible on the tentacles. The present species has generally been supposed to be identical with that of the Mediterranean, of which M. Jules Haime has given an elaborate memoir (Ann. d. Sci. Nat. Ser. 4, i. 341). But in that species the arrangement of the mesenteric septa, — which M. Milne Edwards (Hist. Nat. des Coralliaires, i. 308) gives as generic, differs so importantly from what obtains in ours, as to demand a revision of the generic characters. I have therefore con- stituted it a new species, naming it after Mr. W. Alford Lloyd, to whose intelligent enterprise the study of Actino- logy is so greatly indebted, and to whom we owe our acquaintance with this very animal. In the summer of 1856, this gentleman first obtained specimens from the Menai Strait, a fact which I noticed in the " Annals N. H." for July of that year, assigning the species to the Edwardsia vestita of E. Forbes. Mr. Lloyd also himself about the same time communicated two notes on the animal to the " Zoologist," in one of which he stated that he had then obtained eighteen specimens. Since that period he has procured many more, but, as I believe, only from the same locality. Some of these specimens he has courteously presented to me, and has thus enabled me to become personally familiar with the habits of the species. THE VESTLET. 271 The animal is hardy in the aquarium, bearing even the confinement of trarel with more impunity than many commoner species. It is large and handsome, with a striking and noble aspect, and as it lives habitually expanded, and manifests considerable vivacity, it is a very desirable acquisition. The appearance of its felty tube is, however, repulsive ; but this I have found by no means essential to its comfort, and have managed to dispense with it, by the following device. Having prepared a glass tube of suit- able size, by cementing it perpendicularly to a stone of sufficient weight to maintain its stability in an upright position, I carefully removed the animaPs own case, and dropped the denuded body into the new lodging. The Cerianthus, in every instance, became immediately at home, presently lengthened itself, and expanded at the margin of its new abode ; and, as if the protection hereby afforded were sufficient, it threw off a new natural coat, only to such an extent as did not interfere with the sight of the body through the glass. Another advantage is secured by this treatment ; for whereas naturally the animal burrows in the mud, so that only the expanded flower is visible, and when put into a tank sprawls uncouthly along the bottom, the upright glass tube exposes the entire animal to observation, while it is protected from injury. I have specimens now which have been kept for many months in these circumstances, and are still in the highest condition. In handling the animal during the process of stripping off the coat, it contracts by strong, sudden, and repeated jerks, at each becoming shorter. In these contractions the water in the visceral cavity is forcibly ejected from the terminal pore. This ia not placed at the extreme point, which is marked by a depression, and by the convergence of lines, but is considerably excentric. I have also seen water 272 ILYANTHID^. ejected at intervals by the same orifice, when undisturbed, and that so forcibly as to hurl the floating atoms to the distance of two inches. I am pretty sure that I have also seen an inflowing current ; but this is more gradual, and therefore less conspicuous. The orifice must be considered as only a provision for respiration, and not as a termination to tKe alimentary canal : the half-digested food is, as usual, discharged from the mouth. The Vestlet feeds freely in captivity, greedily accepting fragments of raw flesh, and also skilfully catering for itself. One evening I amused myself with observing it capture its prey. It was one of those mentioned above, set in an upright test-tube^ in an old-established tank, close to the side. The water contained a large number of minute Entomostraca, which, when the candle was placed near the tank, flocked from all parts to the light. I thus was able to direct the migrant crowd to any point that I pleased ; and so brought them, when pretty well assembled, to the quarter which the expanded tentacles of the Cerianihus occupied. One and another were continually coming into contact with the tentacles ; and it was highly interesting to mark the unerring certainty with which each was arrested the instant it touched a tentacle. No matter whether the foot, middle, or tip of the organ were touched, the little intruder inevitably adhered as if birdliraed, and apparently without a struggle ; when immediately, with the most beautiful ease and precision, the fortunate tentacle jerked inward, — all the rest remaining as they were, — and, deliver- ing the prey to the grasp of the gular tentacles, in a moment resumed its expectant position. So numerous was the giddy throng, that this manoeuvre was every moment in practice, with some or other of the tentacles ; so that scores, certainly, of the Water-fleas were captured while I was observing. THE VESTLET. 273 Mr. E. Edwards, of Menai Bridge, who has politely sent me a peculiarly fine specimen, has also favoured me with the following interesting note of the haunts and habits of the species. " The only account I can give of the Cerianthus is, that I have found it in the Menai Straits in two distinct places, about five miles apart. " The ground is a mixture of stones, gravel, and mad. The disk (some of a light and some of a dark colour) when first seen is on a level with the surface of the ground, but on approaching instantly disappears into its sac. " The operation of taking it is difficult, as on the least disturbing of the ground it slips through the sac and is lost. The plan I adopt is to surround it with two or three spades, and each to act at the same moment, so as to undermine it in an instant, and press the ground, which causes its escape to be more difficult." Mr. Holdsworth informs me that he found a specimen of this species * at the island of Herm, near Guernsey. " It was close to low-water mark, buried among mud and stones, with a large piece of granite covering it. Not more than half an inch of the tube was exposed when the stone was removed; and I found the rest winding about the irregularities of the ground in a most tortuous manner, turning sharp comers in its course downwards." M. Haime ( Op. cit.) furnishes us with some interesting details of the development of C. membranacens, which doubtless apply equally well to the present species. " The young," he observes, " which I obtained, all died in the course of a few days. I never found any young advanced, within the parent, as is so common with Actintce ; but the eggs, which float freely there, had already passed the first * It is right, however, to observe that the distinction between this species and C. meinbranaceiu was not then suspected. 274 ILYANTHIDJE. period, and I had no opportunity of seeing their segmen- tation. All were strongly ciliated, and tlierefore were already larvae. They were oval in form, § millim. iu length. One end becomes concave, the other conical. In the centre of the former an opening forms, through which granules escape, and this becomes the mouth ; the escape of the granules leaving the visceral cavity. Soon around the mouth four minute tubercles bud, which become tentacles ; then two other tubercles nearer the mouth form lips ; meanwhile the body becomes smooth, and cylindro- conical. " The young lived in this state ten or twelve days ; and attained one or one and a half millimetre in length. The body continued entirely ciliated, and was become very con- tractile. They swam freely in the manner of a Medusa. mouth downward, by means of elongations and shortenings of the trunk, and by openings and closings of the ten- tacles. Sometimes they would oscillate, or revolve on themselves." Arachnactis. Lloydii. Cyathophylliada3. [membranaceus.] '^Cbbianthus (?) VERMicuLARis (E. Forbes). Dr. Johnston, in his "Brit. Zooph." Ed. 2, p. 222; pi. xxxviii. figs. 2 — 5, has described and figured, on the authority of E. Forbes, under the name of Act. vermicu- larts, what seems either the young of the preceding- species, after it has become stationary, or else a near ally to it. It is described as " 0^ long," and the larger THE VESTLET. 275 teutacles "02^;" but what the integer is to which these fractions refer we are not informed. There is doubtless some error, as in the description these organs are called '* long; " and the figures, which are rude enough, are said to be " of the natural size," and these represent the animal as 1^ inch in length, with the tentacles, both marginal and gular, about ^ of an inch. A slender cylindrical column, Avith a trumpet-shaped margin, a funnel-shaped disk, two kinds of tentacles, and a slit-like mouth, — this animal possesses in common with the Cerianthus. It is repre- sented, indeed, as standing erect, with the base attached in the manner of an Actinia ; but this was probably drawn om assumption, and the attachment may have been similar to that which I have described in other Ilyanthidoe. Professor Forbes sajs the base was "not expanded," which vours this supposition. No tube or case is alluded to, but it may be that this is developed only at a later period of life. The specimens were dredged in fifty fathoms in the Shetland Seas ; the column was greyish pink; the disk and gular tentacles white ; the marginal tentacles fulvous. It gave out a vivid phosphorescent light when irritated in the dark. T 2 276 TRIBE IL— CARYOPHYLLIACEA. The large number of tentacles in the polypes of this tribe allies them to the Astejeacea, and at the same time separates them from the Madreporacea and Antipa- THACEA. Moreover, while the mode of increase in the compound species, by gemmation of the sides or base, removes them from the former, it affiliates them to the latter tribes. The majority of species deposit a corallum of lime, the calices of which are many-rayed. In compound species, the interstices between the corallites are not occupied by prolongations of the septal plates, but are granulous or porous, or sometimes faintly channeled. The stony plates (septa) are nearly or quite entire, rarely denticulate. Within the corallum the septa are connected laterally only by very distant dissepiments, if at all, never by series ot transverse plates. The stars, in a transverse section, are simple ; the chambers being rarely crossed by dissepi- ments : the calices are very commonly cylindrical, with narrow plates, arranged neatly around, and have often a broad bottom, generally porous and convex (Dana). The vast majority of Caryophylliacea are coralli- genous ; but this statement will not apply to those which belong to the British seas : for of the seventeen species presently to be described, seven are destitute of a corallum. So far as I am acquainted with them, the tentacles of our native species (with the exception of Zoanthus) diflfer from those of our Astr^ACEA, in having the cnida not lodged in the substance of the walls, but aggregated into masses which form warts on the siu'face. Most of them have, moreover, these organs terminated with globose heads, destitute of cnidcB, but studded with minute hairs {palpocils). 277 ANALYSIS OF THE BRITISH FAMILIES. Without a corallum.

The members of this Family do not, at any period of their existence, so far as is known, deposit a corallum, or any trace of calcareous matter. They are, moreover, per- manently simple ; for though there is reason to believe that they increase by budding, the polypes so formed quickly sever their connexion with the parent, and become inde- pendent though associated individuals. Thus they are essentially Anemones, such as we have already considered ; yet there is something in their aspect which at once betokens their affinity with the Corals. In particular, the tentacles have the singular structure and knobbed form already noticed as peculiar to this tribe : and, contrary to the universal rule in the Astrceacea, they increase in size outwardly, — the outer row containing the largest. The body, adherent by a broad base, is fleshy or pulpy, copiously lubricated with mucus, and sometimes separating the outer skin into a deciduous epidermis. The surface is not furnished with suckers, nor pierced with loopholes. There are no acontia, but the craspeda are numerous and large, and their contained cnidcB are remarkably developed.

Deep water, off Isle of ilan, on nullipore beds : deep water, four leagnes west of Falmouth, on a valve of Pecten maximui. The late E. Forbes first obtained this interesting form in August, 1840, and assigned to it its generic and specific names; the former from Kdirvrj, a chimney, from its re- semblance to a chimney-crock, of which suggestion I have availed myself to make an English appellation. He tells us little of its history beyond what I have embodied above ; except that it is an active creature, changing its form often, but always presenting more or less of a tubular shape ; and that the upper part of the body can be retracted within the column as low as the commencement of the epidermis. Mr. W. P. Cocks has since obtained a second specimen. This was considerably smaller than Forbes's, but agreed with it in essential points. Mr. Cocks has kindly put into my possession some notes of his specimen, which have enabled me to add a few details to Forbes's diagnosis ; and also a coloured drawing made from the living animal, which I have copied in my Plate IX.

Greenly, being on a visit to Ilfracombe, found in a crevice of the slaty rock at Bull Point, at extreme low water, this magnificent species, which lived in his possession till the following April. To his courtesy I owe copious descriptions and drawings made from the animal while in life and health ; by which I am enabled to draw up the foregoing diagnosis. I forwarded to him for comparison some drawings which I had by me of Mr. Thompson's Gorynactis heterocera ; and the agree- ment of the two forms in all essentials, and especially in the singular shapes of the diverse tentacles, showed that they were of one and the same genus, which was thus proved to have characters that called for its separation from Gorynactis. At the period last named my kind corre- spondent forwarded the specimen to me : but it was already dead; and while it retained its form and colour, I was precluded from adding anything to my knowledge from personal observation. In captivity the animal was lively and extremely sensi- tive, retracting its disk with remarkable suddenness and rapidity on alarm. It early crawled from the piece of slate on which it was captured, and took up a position on the side of a finger-glass in which it was kept. The tentacles were observed to vary the shape of their knobs, within slight limits: one here and there in the outer row occa- sionally approaching the hastate form of the next row. sanguinea, AUGUSTA. heterocera.

Of the second row the knobs consist of two swellings divided by a constriction, each swelling oomposed of two globose lobes placed side by side, with a mucro terminating the whole. Of the two innermost rows the knobs are nearly sessile j they are rondo-quadrangular, or shaped somewhat like a loaf of bread. In the expanded state all these organs lie nearly horizontal, pointing outwards, and slightly overlapping ihe parapet. TENTACLES OF A. HETE- BOCKRA. 286 CAPNEADJE. Mouth.

The south of England and south-west of Ireland : deep water. This fine species, only inferior in beauty to the one just described, was dredged by Mr. W. Thompson in Wey- mouth Bay, — eight fathoms, gravel,— in September, 1853. As I was at Weymouth at the time, he kindly showed it to me, and I thus had the opportunity of making careful drawings and notes from the life. We considered it as more nearly allied to Corynactis than to any other recognised form ; and, the species augusta being then unknown, I was induced to suggest the specific name heterocera, which Mr. Thompson adopted^ from €T€po<;, diverse, and Kepa^, a horn. In confinement, the species appeared hardy. When detached it readily adhered again ; soon expanded after having been provoked to close ; often passing from one condition to the other many times in quick succession. It is subject to very little change of shape, in this respect contrasting with Corynactis, which is most protean. Mr. Thompson observed that it opened slowly, exserting the tentacles of one-fourth of the periphery, while the rest remained closed. These organs were nearly motionless. THE YELLOW IMPERIAL. 287 When a piece of meat was dropped on the open disk, it remained awhile apparently unnoticed; at length the animal slowly bent itself on one side, and the unwelcome morsel rolled across the tentacles and fell to the bottom. When Dr. E. P. Wright was on the south-west coast of Ireland, in July, 1858, he found, at Crookhaven, a small number of specimens of this species, agreeing with Mr. Thompson's description in every particular, except their smaller size. He kindly sent me tliree, but they all died xn transitu, from the length of the journey. Dr. Wright says " it can assume an almost transparent appearance," — which was not the case with the Weymouth specimens ; but which assimilates it to Corynactis. He observed also that the outer tentacles were reverted, so as actually to touch the rock, which gave it a strange aspect. The circles of tentacles resemble a coronet of pearls ; and searching for a name by which to distinguish the genus, I was reminded, by this peculiarity, of the diadem which was the distinctive badge of the Eoman Augusti, and by the splendid colours of the animals, of the no less imperial gold and purple. I have therefore called it Aureliania, after him who of the Roman emperors first wore the diadem and the gold-embroidered purple.* The splendid appearance of the zoophytes, especially of the preceding species, must plead my apology for so presumptuous an appropriation.

This is one of the most exquisitely lovely little gems of the aquarium ; and fortunately it is abundant on our south- western shores, and very easily preserved in confinement for an indefinite period. In the Channel Islands ; from Torquay around the promontory of Cornwall to Ilfracombe THE GLOBEHORN. 291 in the Bristol Channel ; and again on the indented coast of Cork, it occurs in profusion on the perpendicular and over- lianging rocks ; while it has been dredged in deep water oflf various points of the same shores, and even in the land- locked gulfs on the north-east of Ireland. It is almost invariably found in close-set clusters of a dozen to fifty ; and though several distinct varieties frequently occur in the same immediate vicinity, yet the individuals of the same group are invariably found to agree in their tints. Hence I incline to believe that these groups are produced either by the spontaneous fission,* or the gemmation of a primitive polype. I have seen some which were evidently connected together by the base, the process of separation being incomplete. It is somewhat difficult to detach the animals ; their bodies are excessively pulpy and tender, and under irrita- tion they excrete a vast quantity of mucus, so dense as almost to equal in consistency the substance of their own bodies, and which might sometimes assume the form of an epidermis. If carefully detached, however, they will re-adhere ; and I have known individuals even crawl off from a fragment of rock to the sides of the tank. In general, however, they are stationary, and even sluggish ; allowing their tentacles to be handled without contracting. They open very freely, and ordinarily remain expanded. In a well established aquarium, they will live for a long period ; I have some which have lived in captivity fifteen months. They seem in other respects tenacious of life ; for I have seen the tentacles and margin of one side appa- rently healthy and contractile, while the whole opposite side had become a putrescent mucus, sloughing away. AU the varieties are charming ; perhaps none more so than the translucent white one which I have named Coina. * Several in the possession of Mr. Holdsworth spontaneously divided, u 2 292 . CAPNEAD^. The expanded disk, with the opaque white tentacle-heads scattered over it, looks like what the ladies call " spotted muslin ; " Vvrhile, under a lens, the tentacle-stems resemble lace, or figured blonde. Around Torquay the species exists in much variety. On the shadowed sides of the perpendicular wall-like rocks, near Meadfoot, I have seen, at extreme low water, countless groups, displaying their lovely little coronets within reach of my hand, as I was pushed in a small boat through the narrow passes of the islets. Dr. E. P. Wright finds it in amazing profusion, " covering whole rock-pools," at Crook- haven. He says that some of these expanded to nearly an inch in diameter, — dimensions which far exceed those of such as I have seen. They have been occasionally found on roots of Laminaria, and Mr. Cocks has taken a number, half-digested, from the stomach of a Plaice. They feed readily on minute morsels of raw meat; which, however, must be laid on the disk with great caution, or the animal will close. In taking-in the morsel the Cory- nactis does not protrude the lips to embrace it, nor close the tentacles over it, like the Actimcc, but dilates the mouth slowly and uniformly, until the lips form a circle of great width, nearly as wide, indeed, as the disk, within which the visceral cavity, like a broad saucer, is seen, with the coiled craspeda lining its sides and bottom. Into this gaping cavity the morsel is drawn, and then the lips gradually contract and embrace it, finally protruding in a pouting cone. This is exactly the manner of CaryopJiyllia Smithii. There is much in the appearance of this animal which agrees with CaryopJiyllia: tlie colours and their distribu- tion, the general translucency of tlie tissues, the form and crenation of the mouth, and, in particular, the shape, arrangement, and minute structure of the tentacles, are Tit& GLOBEHOEN 293 SO exactly those of the Coral, that I have often more than half suspected that the former is the immature condition of the latter. Both are found in the same localities, in the same haunts, and often in close proximity, which helps the conjecture. No trace of calcareous deposit is found in the tissues of Corynactis when crushed between plates of glass ; but the observations of Mrs. Thynne* have shown that the young of Caryophyllia attain a large size without depo- siting a corallum. But the results of this lady's experi- ments, — so far as they go, — tend to negative the identity of the two animals J though I must still consider the species as in near affinity. Under the microscope the tentacle is seen to consist of a transparent thick-walled tubular stejii, in which longi- tudinal fibres are conspicuous, and a globose head. The stem is studded with large oval warts, varying in shape and size, and without orderly arrangement, but set trans- versely on the whole, very close together in contraction, but separated by wide spaces when the tentacle is elongated. Both the head and the warts are pellucid in themselves, but are sub-opaque from their contents : both are thickly covered with palpocils, while the trans- parent portions of the stem are clothed with cilia. In conformity with the great predominance of the longi- tudinal over the annular muscular fibres in the tentacle- wall, the contraction of these organs is in length rather than in diameter ; or at least that of the diameter is only the result of elongation. The globose head seems non- contractile ; and hence, when the stem is much elongated, we see a spheryile at the tip of a narrow foot-stalk, while, when the form is much contracted, the head remaining unchanged, we have the " corrugated cup " of jVIt. Peach, with the sphere seated as it were in it. * Annals Nat. Hist, for June. 1859. 294 CAPNEAD^. The cnidce in this species attain a higher development than in any other zoophyte that I am acquainted with, and hence they afford peculiar facilities for the study of these interesting organs. No one familiar -with this beautiful little creature can for a moment doubt that the two supposed species, viridis and Allmanni, are in truth but one. The former name must of course be retained, as having the claim of priority. It was given by the discoverer, Professor AUman, who found it, where since it has been so abundantly met with by Dr. E. P. Wright. The name Corynactis is formed from Kopvvr), a club, and uktU, a ray. There are several exotic species, whose tentacles are tipped with globose knobs; — as Act. glohulosa (Quoy et Gaim.), A. ghhulifera (Ehrenb.), and A, clavigera (Dana) ; but I know too little of their structure to pronounce upon their degree of affinity with the present. The clavigera, a species of large size from the Pacific Islands, may perhaps be a link of connexion between C-orynactis and Sagartia. Guernsey, T. D. H. : Torquay, P. H. G. : Dartmouth, E. W. H.

The polypes in this family are persistently fixed, and aggregated : the adherent base extending itself laterally, and sending up new polypes at inten-als, which remain permanently united to each other, and to the primary polype. The extension may be in irregular lines, carrying the polypes in single file; in broad bands, supporting several abreast ; or in all directions, producing large clustered masses, incrusting the foreign body to which they happen to be adherent. This variation in the manner of base-extension has been hitherto considered as so important, that genera have been constituted on thLs character alone, — Zoanthus, including those whose base runs in lines ; Palythoa^ such as form carpet-like surfaces. But e\'idence will presently be adduced to show that these variations may occur in the same species. Again, the genera Mammilifera and Corti- cifera, of Lesueur, have been formed for clustered species ; the fonner being fleshy, with a mucous surface, not en- veloped in sand ; the latter " inclosed iu cellules of sand, agglutinated ; the cellules themselves agglutinated for their whole length, and forming a corticiferous expansion." It appears, however, from Lesueur's own description, that what he considered " cellules," inhabited by the animals, was simply the integument of each polype, in which sand was imbedded. The presence or absence of sand, however, can in no wise be allowed to constitute a generic distinc- tion. I cannot, therefore, recognise in the family more than the single genus, Zoanthus. 296 GENUS I. ZOANTHUS (Cuvier). Actinia (Ellis). Zoantha ) Zoanthus ^ Mammilifera > (Lesueue).

Narrow, irregtilariy creeping, soft, elastic, fleshy to the feel, very sensitive ; invested with sand, like the column. Column. Cylindrical, rising to about three or four times its diameter ; smooth, transparent. Margin cut into twelve or fourteen (generally the latter number) large fleshy triangular teeth, which are connected by a thin web of transparent membrane, the inner layer of which is composed of transverse fibres, the outer is gianular and cutaneous. In a state of semi- contraction, these teeth form strongly-marked converging ridges on the flat summit of the column. Investment. Fine sand, evidently not a secretion, but extraneous, imbedded in the epidermis, — the fragments (in Torquay specimens) being of different colours, some being of white limestone, others of red sandstone. When the column is much distended, the grains of sand become considerably separated, and we can distinctly see through the transparent and smooth integuments into the visceral cavity. Thus the sand forms manifestly only a single layer. Only very minute grains are used, and there is very little difference in their size. Dtsl: Generally flat or slightly concave, but protrusile in a conical form. Radii apparently di.stinct, but only because the upper edges of the a^ta appear through the perfectly transparent disk. 298 ZOANTHID^. Tentacles. Twenty-eight (twenty-four in less mature specimens), arranged in two rows, fourteen in each : those of the inner row correspond to the marginal teeth, those of the outer are intermediate. They are sub-equal, taper, bluntly pointed, and, when extended, about equal in length to the diameter of the column, hollow, not warted, with thick walls, which, in contraction, fall into transverse or annular corrugations. They are pro- truded in a brash, but, when fully expanded, spread out horizontally. Month. Lip shai'p, much crenated, protruded after feeding. COLOUE. Investment of root-hand and column. Pale brown, the hue of the sand. Column. Beneath the investment, transparent and colourless. Disk. Pellucid reddish-grey, dusted with excessively minute white specks. Tentacles. Translucent, nearly colourless ; but each has a small mass of opaque white pigment on the internal surface, just at the tip : the aggre- gation of white points has a pretty effect. Mouth. Lip opaque white. Size. None that I have seen alive exceeded one-eighth of an inch in diameter, and about thrice that height in extension. In contraction the button is usually about a line in height, Mr. Holdsworth has obtained specimens much larger than these. LocALixr.

If wc selected a single specimen of each of these varieties, THE SANDY CEEEPLET. 299 and compared them, without any other information, nothing would be more manifest than that we must assign them not only to distinct species, but even to distinct genera. ]Mr. Alder has favoured me with many specimens, obtained by Mr. Barlee, at Shetland, some of which, each consisting of several full-grown polypes, are perfectly independent and compact, showing not the slightest trace of adhesion to any foreign body, nor of any part that can be distinguished as a root-band. Thus, in the specimen figured in Plate ix. fig. 9, three polypes diverge from a common centre ; others are similarly formed, sometimes with a triangular dilatation of the point of divergence, which thus becomes flat, but still with both surfaces equally entire. I have not seen more than three polypes on any free specimen. But among these, we see specimens at first sight hardly distinguishable from them, except by a slight globosity at the point of divergence : when we turn these over, we dis- cover that the globosity has been moulded on a minute shell, evidently that of a Xatica. Then others occur, in which the shell, almost always a Natica, is larger, and there is a distinct basal carpet uniformly spread over it, of the sand-covered flesh, from which spring four or more polypes : these are manifestly identical with tlie free ones. But on larger shells the colony of polypes is made up of more individuals ; in one specimen before me, in which the shell is about the size of Xatica Alderi, there are nineteen polypes. In every case the basal carpet has spread in imiform thickness over the entire shell, following the form accurately, and extending to the edge of the outer lip, and clothing the rotundity of the inner lip as far as the eye can follow it. Strange to say, in every example, the shell itself has wholly disappeared, and all that is left is the exact model of it in the sand-clothed membrane, or basal carpet, of the polype. 30ft ZOASTHIDM. In this condition, the zoophyte was mistaken by Dr. G. Johnston for a Sponge, and he has accordingly figured and described it in his " British Sponges," under the name of Dysidea papulosa. I do not see in what single particular such specimens diifer from the genus Palythoa of Lamouroux, as this is characterized by M. Milne Edwards : — " Poly- pUro'ides cylindriques, naissant sur une expansion hasilaire memhraniforme, lihres latiralement, ou sondes entre eux, et formant des masses encroHtantes / " * and thus we find the same species in some circumstances a Zoanthus, in others a Palythoa. Nay, more, as if to increase the confusion. Dr. J. E. Gray has actually made a new genus for the inter- mediate free condition, which he calls " Sidista."'f The only way in which I can account for the free condi- tion is by supposing that the germ was, in those cases, deposited on a fragment of shell or stone so minute as to be completely overspread and enveloped by the increasing base.^: The unvarying disappearance of the shell in the diffuse variety is more remarkable, and seems to imply a corrosive or absorbent power in the base. That the Shetland and Northumberland specimens are identical with ours in Torbay seems pretty certain ; for Mr. Alder, who has had opportunities of seeing both in the living state (some from the north having been sent him alive by Mr. Barlee, and some from the south by myself), can see no specific diversity between them. But that they are the same species as the Zoanthus Couchn of the Cornish coast, 1 assume rather than prove. It is unlikely that there should * Hist, des CoralHaires, i. 301, t Annals Nat. Hist. Dec. 1858. J Mr. Alder remarks on these varying conditions as follows : — " I have come to the conclusion that when the zoophyte has free space on a stone it runs over it as Zoanthus ; but when the base is confined to a shell, it spreads into an uniform crust, as Palythoa. The loose branched speci- mens, I conclude, having affixed themselves to some minute object not affording a proper base of attachment, take a tubular form until they terminate in polypes."— f/w litt.J THE SANDY CREEPLET. ^01 he two species of the same uncommon genus, having so many points in common, found in so close proximity as the Devon and Cornwall coasts, and yet there are glaring dis- crepancies between Mr. E. Q. Couch's published descrip- tions and the characters of our animal. He describes the surface as " glandular," the form as frequently "contracted to an hour-glass shape," and as being very versatile ; the habit as sluggish, and slow to change ; the tentacles as " darker at the extremities than at the base ; " not one of which particulars do our specimens confirm. My first personal acquaintance with the species I owed to Mr. Holds worth, who dredged several colonies in twelve fathoms, off the Ore Stone, near Torquay, in October, 1858, where further researches show it to be quite common. They were of the variety linearis, aflaxed to fragments of slate and old valves of Cardium rusticum, twenty or thirty polypes on each, nmning in sinuous bands from half a line to three lines apart in the series. The colonies meandered over both surfaces of the fragments. One of these colonies my friend kindly gave to me, and it has lived now ten months with me. The pol^-pes are by no means sluggish, but are continually opening and closing with considerable vivacity. AVhen completely con- tracted, each polype is a cylindrical button, with the summit round and depressed in the centre. As expansion proceeds, the centre evolves, and the summit becomes nearly flat, with the twelve or fourteen strongly marked marginal ridges radiating from the central orifice. The central aper- ture enlarges, and the white tips of the tentacles are seen protruding, and presently the tentacles themselves, blunt and pellucid white, which soon arch outwardly. They feed readily on raw flesh or earthworms, but will take only very minute fragments. These, however light their contact, cause the tentacles to retract ; but if the 302 ZOANTHID^. morsel be laid gently on the truncate summit of the closed column, the converging teeth appearing, it will remain there until the animal seizes it. The tentacles are protruded one hy one so cautiously that the meat is not disturbed, and soon we discern that it is environed by a wall of tentacles, and that the mouth is gaping widely to embrace it. After feeding, or when food which has been resting on the disk is suddenly taken away, the whole disk is protruded as a cone, on the summit of which the open throat forms a wide valley, coarsely furrowed. The creeping-band is very sensitive ; when touched with a needle-point, all the polypes suddenly contract, yet not quite simultaneously, but in the order of succession cor- responding to their proximity to the point of attack. Mr. Holdsworth tells me that " the polypes live very well when detached from their support." The generic name is formed from ^wov, an animal, and dv6o<;, a flower ; the Englisli term is meant to express its peculiar habit. Shetland, G. Barlee : Northumberland, J. A.: Guernsey, J.

Torbay j on rock, between tide-marks. This very distinct and interesting little Zoanthus occurred in a large colony at Broadsands, near Brixham, in March, 1859. They were spread on a rock of soft red sandstone, and so numerously, that, in the fragment which came into my possession, I counted sixty polypes in a space of one-and-a-half inch square. At first their character was much disguised by the crowded sand- tubes of a very minute Terebella, out of the tangled masses of which the Zoanthi were peeping. When these were cleared away by the careful application of a needle-point and a hair-pencil, the basal expansion was apparent, an irregular broad band, with several polypes abreast, as described above. The texture of the band appears less compact than in the preceding species, with which I com- pared it, having a more cellular appearance ; the grains of sand too are coarser. The species is hardy, my specimens being healthy at the present time, after three months' captivity. They are evidently diurnal in their habits and predilections, gene- rally expanding under the stimulus of sunlight, but always closing at night. When the polype is irritated it shrinks nearly to the epidermis, and from the whole summit throws off a mucus, which presently becomes membranous, and seems identical with the epidermis, Couchii.

My friend favours me with the following note of the capture: — "It was soft and fleshy, without trace of corallum ; the individuals connected by a creeping fibre running over the under sur- face of the stone. I chipped a piece of it off, which fell face-downwards, and I fancy got injured in consequence ; as it never showed any signs of life after I put it into my bottle. I kept it two or three days in expectation that it might recover, but, as it began to decay, I secured the remainder by putting it into spirit." There were about a dozen polypes in the colony, all of the same size, which seems to be good evidence that they had attained adult dimensions. Couchii. Alderi. ?

In this, and all the families which have now to come under consideration, the tissues secrete calcareous matter, which unites into a solid internal skeleton of stone, known as the CORALLUM. The stony substance is chiefly deposited — 1. in the integuments of the base and column, forming the WALL (mtiru^) ; 2. in the septa, forming a series of perpendicular plates (lamellce), which radiate inward from the wall ; and, in some cases, another circle, or circles, of similar plates, palules (pali), which do not reach the wall ; and 3. (as I believe) in the ovarian mesenteries, form- ing a series of plates, generally twisted, in the bottom of the cavity, called the columella. The hoUow centre, formed by the upper edges of the plates, is called the CALICE {calyx). Sometimes the exterior of the wall is fm-nished with longitudinal ribs (costce), which correspond to the plates. The plates are arranged in cycles : those of the Jirst cycle project furthest inwards ; those of the second bisect the interspaces ; those of the third bisect the interspaces thus formed, and so on. The whole of the plates developed in one primary interspace constitutes a SYSTEM. In the TuRBlNOLiADJE the corallum is solid (not porous), simple, with the lamellar interspaces reaching to the bottom of the cavity, and perfectly free. The plates are highly developed, simple, and generally have a granular surface. The ribs are well-marked. X 2 308 I ANALYSIS OF BRITISH GENERA. ^ With palules : adhei-ent.

Simple, constricted in various degrees ; the base generally wider than the summit, and the central region being often less than half the diameter of the latter. Outline sometimes circular, but generally more or less elliptical. Height in general less than the long diameter. Ribs. Well-marked on the upper half, leas distinct on the lower, studded with fine granules. Plates. Forming five cycles, and six systems, but the plates of the fifth cycle * Marked in the Plate " Cyaihina Smithii." THE DEVONSHIBE CUP-COEAL. 311 are wanting in some of the systems. They are broad, granular on both surfaces, with the upper edge very salient and rounded in outline. Those of the third and fourth cycles subequal between themselves, and much smaller than the first and second, which also are mutually subequal. Columella. From twelve to twenty thin plates much twisted, with sinuous edges ; the summits much lower than the pahiUs. Palules. Well -developed, more fleiuous than the septa, of which they correspond to the third cycle. Colour. In general pure white, but in some specimens tinged with a lovely permanent rose-tint ANIMAL. Form. Column. Cylindrical, very extensile, smooth, membranous, invected towards the summit, each invection becoming a tentacle, without any distinct margin. Disk. Flat, but readily assuming a conical form. No trace of gonidial radii, tubercles, or groove. Tentacles. About fifty in number, arranged in three subequal rows : stem conical, membranous, translucent, studded with transverse oblong warts ; head globose, opaque, covered with palpocils. (Plate xii. fig. 4.) Mouth. A lengthened ellipse or a slit. Lip coarsely furrowed, like the lips of a cowry-sheU. Stomach flat when empty, as in Anemones. All the tissues can be enormously distended with water. Colour. Column. A very faint bay or fawn colour, with longitudinal lines of chestnut. Dish. Transparent white, with a broad Vandyked circle of rich chestnut surrounding the mouth. Tentacles. Stem-wall colourless, with the warts deep chestnut; head opaque, pearl-white, sometimes slightly tinged with rose. Mouth, Pure white. Size. CorcUlum. Fine specimens attain a diameter of three-fourths of an inch, and a height nearly as great. Animal. The column when distended frequently stands an inch above the corallum, and exceeds it in breadth by a sixth of an inch on every side ; the tentacles augment the height still further by nearly half an inch. Locality. On various parts of our coast in deep water, attached to stones and shells : Devon and Cornwall, on rocks between tide-marks. 312 TURBINOLIAD^. Varieties, o. Castanea. As above described. )3. Esmeralda. The chestnut here replaced by vivid green in like intensity, except the border of the mouth, which is pale red. 7. Clara. Translucent white. On the perpendicular surfaces of cliffs with a northern aspect, in narrow wall-sided fissures, and on the under sides of fallen fragments of rock forming natural arches, and in dark overhung tide-pools, I have found this beau- tiful Coral in abundance on the coast of both North and South Devon. It is only at the great recesses of the equinoctial spring-tides that it is exposed, though in per- manent pools of ample dimensions it occasionally occurs at the half-tide level. For the most part gregarious in habit, it occurs more in colonies than singly, and twenty, thirty, and even more, are occasionally taken by the collectors from a single pool. It is deservedly a favourite with aquarians; for if removed from the rock with care by a proper use of the chisel, scarcely any species is more hardy, more beautiful, or more changeable in its aspects. I have been informed of a specimen which had been preserved two and a half years, and was then in health. It is free in expanding in captivity ; perhaps its most common condition being that in which the mouth is somewhat open, and the tentacle- heads just peeping from beneath the half-closed margin of the column ; but occasionally, and especially at night, the animal expands to the full, and rears its lovely form far above the level of its stony walls. This condition may, however, at any time be induced by a proffer of food ; an atom of raw flesh cautiously laid on the half-exposed disk is a temptation too great to be resisted. The protrusile lip slowly but evenly expands to embrace the food, and then closes over it, meeting in a puckered knot in the THE DEVONSHIEE CUP-COEAL. 313 centre. The unyielding stony margin of the omachal cavit)' preventing the morsel from being drawn down, as it would be in an Actinia, the whole disk projects pei-pen- dicularly, like a thick pillar, from amidst the tentacles, displaying the dark mass through the pellucid walls. Now presently a great change takes place : the whole of the soft tissues become distended with water, and take on an exquisite translucency and delicacy ; the colmnn swells out to twice the width of the corallum, the tentacles are like transparent bladders full of water, each crowned by its little white globule, and the whole appearance is most beautiful. I have seen under these circumstances the animal extended to more than an inch and a half above the level of the plates. The lip often projects like a thin oval wall, or like the brickwork surrounding a well ; marked with thick perpendicular ridges of opaque white, distinctly defined, separated by interspaces of equal width. This is well expressed in the figures (5 and 6) given by Johnston, after Alder, which are very accurate : figs. 7 and 8 of the same plate, like too many of the zoophytic deli- neations of Forbes, I can only call caricatures. I have elsewhere* given many details of the structure and economy of this Coral, to which I can here only refer the reader. Among them will be found some curious examples of reproductive power; one, in the formation of a new disk, mouth, and tentacles, at the lower end of the corallum, which had been broken firom its base ; and another, of the replacement of a large number of the septa, which had been broken away. Of the generation and development of the species I can say nothing fi*om personal observation ; the smallest I have seen having been about one-sixth of an inch in diameter, with a well-formed corallum of half a line in height. • Devonshire Coast, pp. 108—127. 314 TURBINOLIAD^. Mr. R. Q. Couch, however, says, " In the youngest state the animal is naked, and measures about the fifteenth of an inch in diameter, and about the thirty-second of an inch in height. In the earliest state in which I have seen the calcareous polypidom there were four small rays, which were free or unconnected [i.e. without any wall] down to the base ; in others I have noticed six primary rays, but in every case they were unconnected with each other. Other rays soon make their appearance between those first formed ; they are mere calcareous specks at first, but after- wards increase in size. The first union of the rays is observed as a small calcareous rim at the base of the polype, which afterwards increases both in height and diameter with the age of tlie animal."* From a valuable series of observations made by Mrs. Thynne,-]- it would appear that the Caryophyllia discharges its ova in spring, which in about two days become rotating infusorioid animalcules. In a week or two these afSx themselves, and develop tentacles and a disk, and gradually grow to the size, and even far more than the size, of the parent, with all the characteristic colours and marks, hut without the least trace of a corallum. During the progress of this condition, the individuals increase rapidly by spontaneous fission, the separated portions immediately becoming independent animals. It is difficult to suggest any flaw in the evidence of identity ; but it is to be regretted that the experiments terminated without any sign of the development of a corallum. Double and even triple specimens are not uncommon; and I have seen at least two examples (one of which I now possess) that are fourfold. J The appearance of such speci- mens is exactly that of a branching coral ; and, strange to * Quoted in Johnston's Br. Zooph. i. 199. t Ann. N. H. for June, 1859. . t Such a specimen I have figured in my Dev. Coast, pi. v. fig. 5. THE DEVONSHIEE CUP-COEAL. 315 say, if one alone of the disks be fed, the rest will presently become equally distended, as if partaking of a common life. On breaking one of these double skeletons, however, no communication is found to exist between the cavities ; and hence we must conclude that such instances are due to the accidental fixation of two or more geramules in close proximity to each other, and the coalescence of the cal- careous walls in process of growth. The name Caryophyllia is formed of Kcipvov, a nut, and (f)vWov, a leaf, — q.d. " a nut of leaves" = plates. The specific name is in honour of Thomas Smith, who appears to have first observed it on the south coast of Devon. A curious little Barnacle {Pyrgovia Anglicum) is para- sitic on this species, affixing itself to the outer edge of the plates ; two are sometimes found on the same coral. The corallum is very hard. An hour's rubbing of one on a slab of marble rough from the saw, with a view to a longitudinal section, produced little efiect on the coral, though it effectually polished the marble.

Locality, The Moray Firth ; deep water. It is with some doubt that I refer this and the two following species to the genus Paracyathus. Generally agreeing with its characters, they all have the peculiarity of the union of the palules into a horizontal perforate platform, which does not appear to be the case with any of the hitherto described species. The single specimen on which the above description is founded was forwarded to me by my kind friend, Mr. Gregor, of Macduff, who obtained it from deep water. It is affixed to the inside of an old valve of Cyprtna Islandica, and has the appearance of being recent. The only species of Paracyathus with which this is likely to be confounded is the fossil P. crassus of the London Clay ; but from this it may be distinguished by the union of the palules, by the ribs being proportionally thinner and more remote, and by the diversity of their upper and lower portions. Paracyathus is derived from irapa, near, and Kva6o<;, a cup (the element of Gyathina). I have assigned a specific name from Taxilium, the ancient appellation of the pro- montory now called Kinnaird's Head, off which the specimen was taken. Caryophyllia. Taxilianus. crassus.

Looking over the cabinet of Dr. Howden, of Montrose, last winter, my eye fell on this little Coral, which seemed new to me. Its owner was so kind as to transfer it to my possession, when, on careful examination, it proved to be an unrecognised species, with the characters above enumerated. It may be distinguished from P. caryophyllus by the relative proportion of the height to the diameter, and from all other described species by the number of septal cycles. Dr. Howden dredged the specimen off Ord Head in Bressai Sound, Shetland, in thirty or forty fathoms, on a bottom of small stones, to one of which it is attached. In March of the present year Mr. Gregor sent me, on a valve of Lutraria, a specimen, which appears to be of the same species, but of younger age. It is not more than half the size of the former, but in other particulars agrees sufficiently. On my putting it into sea-water on its arrival, the pellucid flesh came up and filled the intersepts, giving satisfactory evidence of its freshness. Unfortunately it had been sent through the post, packed dry ; it was probably alive when despatched. The whole corallum in this speci- men is of the purest translucent whiteness. It came up on a fisherman's line from the Moray Firth, in about forty fathoms, hard bottom. The specific name is from Thule, the ancient designa- tion, as presumed, of the Shetland Isles. Taxilianus.

For this veiy distiuct and remarkable little Coral I am indebted to Mr. James Macdonald, of Elgin, who obtained it from Lossiemouth, in October, 1858, attached to a valve of Gyprina, from the deepest part of the Moray Firth. There is no other species with which it can possibly be confounded, the expansions of the ribs presenting a very striking character. They remind me of the immense but- tresses which surround the base of the giant Ceiba of the Jamaican forests. To this feature I have alluded in tlie specific name, which is formed from Trrepdv, a wing, and TToO?, a foot. My friends, Messrs. Macdonald and Gregor, speak of other Corals having at various times come under their notice, but they had always been set down, like these now recorded, as Caryojjhyllia ^mithii.

I am sorry that I can give no information about this species additional to what is already known, viz., that it exists in a living state on our coasts, and that the skeleton is preserved in cabinets. That in the British Museum is the only one that I have seen. As long as naturalists con- tent themselves with merely preserving the skeletons of the animals they meet with, but little progress can be made in a knowledge of their history.* The present species is said to have been dredged alive off Scilly, by Mr. MacAndrew, after whom it has been named, and off Arran, on the west coast of Ireland, by Mr. Barlee. The generic name is from acfyrjv, a wedge, and rpoxo^) a top, in allusion to the form of the corallum.

Simple, straight (or else with the base considerably curved laterally), compressed above (the axes of the disk being 60 : 42 in general ; in one example, however, 60 : 50), but rounded in the lower two-thirds, pedicellate; the body and the pedicel varying exceedingly in their rela- tive proportions, the former being to the latter as 1 : o in one example ; in another, as 1 : 1; in another, as 1 : 1'2, — no two of the four specimens in my possession being alike in this respect. The pedicel is surrounded by four to six constrictions, varying gi-eatly in their relative distance : these separate nodes are more or less swollen, of which one, a little above the base, is usually more ventricose than the rest; the pedicel generally enlarges upwards, but its distinction from the body is marked by an abrupt shoulder. Bibs. About as wide as the interspacss, distinctly traceable only as far down as the termination of the body ; their course is irregularly angular ; the primaries and secondaries terminate at the shoulder in prominent knobs. On the pedicel only the six primaries are distinguishable, and these arc then crossed by numerous strongly indented zig-zag folds, of which the higher angle is on the rib, the lower in the interspace.

In its tendency to a curved form, howcTcr, as well as in its pedicellate character, and especially in the presence of a well-formed basal area, which appears to have been a point of adhesion, it displays so much aflSnity with Ceratotrochus (according to the diagnosis of M. Milne Edwards) that I was at first disposed, to assign it to that genus. The four specimens that I have above described have been entrusted to me by my kind fiiend, Dr. E. Perceval Wright, of the Dublin University, with whose name I have honoured the species. They were dredged by G. C. Hynd- man, Esq., among shell sand, from a turbot bank off the coast of Antrim, in 1852. I have introduced the tiny form into this work, believing it to be an existing, and not a fossil species. Professor 328 TURBINOLIAD^. Milne Edwards, indeed, considers the SjpJie^iotrocId with papillate and crisped ribs to be in no case later than the eocene deposits ; while those with smooth ribs he looks upon as invariably belonging to higher strata, and reaching to the present period: but this is a canon which a new species may at any moment overturn, if it be not already subverted by the 8. nanus (Lea) of the eocene of Alabama. Dr. E. P. Wright mentions, as a suspicious circumstance, that many pleistocene shells do exist in the bed of shelly sand, where these specimens were found. But this does not confirm Professor Milne Edwards's rule ; for, so far as that could decide the question, it would prove not only that this crisped Coral is not recent, but that it is certainly as old as the miocene. Dr. Wright says : — " I have reason to think, however, that they are not fossil;" and the same is my own impres- sion, though I can scarcely assign any definite grounds for it, except the fresh appearance of one or two of the speci- mens. Some of them are rubbed, and one is polished externally. The uniformity in size of the individuals, and the full development of the plates, indicate a probability that, minute as they are, they have attained adult age.

Simple, free, but with traces of having been adherent iu infancy : the base with a great inferior surface, triangular, flat, often concave, separated from the superior surface, which is equally triangular and convex, by a sharp edge on each side. Ribs. Large, often indistinct, unequal; the primaries sometimes armed with minute tubercles. Calice. Very wide and deej) ; the edge almost circular, crisped with minute sinuosities. Plates. These are so irregular that it is difficult to count the cycles, but they are at least four. Those of the first and second are more than twice as high as the rest, and reach to the centre of the cup, where they unite, but irregularly : the others are lower and shorter in gradation, the lowest projecting little within the margin. All are perfectly separate throughout, extremely thin, sharp-edged, the surfaces set with minute granules often running in curved lines : the free edge of all is arched, and their greatest width is one-third from the summit. The primaries and secondaries ai'e very salient, and the edge of the calice seen in profile forms eleven or twelve triangular lobes. Columella and palules wholly wanting. ANIMAL. Form. Column. Actinia-like, without any trace of gemmae. Disk. Radii fine, distinct. Tentacles. About 140, in four rows, close-set, iri'egular; the innermost three or four times as large as the outermost : stem cylindro-conical, THE SCARLET CRISP-CORAL. 331 covered with large round prominent warts ; head globose, smooth, imper- forate ; very contiactile, but not retractile. Mouth. A wide slit in the direction of the long axis : lip crenate, with forty to sixty-five deep furrows. Colour. A brilliant orange-scarlet ; a little lighter on the inner tentacles : the furrows of the lip intense blood-red. Size. Corallum. About one and a half inch in diameter, and a little less in height. LOCALITT. The coasts of Norway and Shetland : deep water. Of this species, bj far the largest and noblest of the simple European Corals, a specimen was dredged bj Mr. MacAndrew about twenty-five miles off East Shetland, in ninety fathoms. The individual was broken by the dredge, and only a portion of the corallum was secured, which is now in the British Museum. There can be no doubt, however, of its identity. A considerable number of examples have been obtained by Mr. Sars at Oxfjord, close to North Cape, the extreme northern point of Europe. It lives at an amazing depth, even from 150 to 200 fathoms, where the pressure of the superincumbent water must be immense. Clear as are the waters of the northern seas, so vast a volume of water must surely absorb nearly the wh> le of the rays of light, and the rich hues of the animal arc therefore the more remarkable. It lies free on the mud or clay, never having occurred with evidence of recent attachment. The generic name is formed from ou\o9, crisped, and Kva6o'gia equal, and the plates of the third or fourth {magnified). cycle are occasionally larger than those of higher rank, even in the tame system. Size. Individual corallites one-eighth of an inch in diameter, and nearly one fourth in height. AsniAL. Undescribed. LOCALITT. Weymouth Bay : deep water. When this neat and interesting little Coral first came into my hands, I thought, notwithstanding some peculiarities, that it must be referred to the PhyUangia Americana, a native of the West Indian seas, and so announced it. But I see that there are incongruities which prevent its identification with that or any other recognised genus, and I have therefore founded a new one to receive it. It has much in common with Angia, as well as PTiyUangia, but the above diagnosis will, I think, warrant my decision. In forming a generic name, I have followed the plan of M. Milne Edwards in using a common element for the genera of a given family ; though perhaps a little heterodox for stanch Linneans, it has advantages. Taking then the z 2 B40 ANGIADiE. element angia, from dyyovWov, a leaf, and the specific alludes to the royal colours in which the animal is arrayed. Ilfracombe, F. H. G. ; Lundy, C. K. REGIA. [cylindrica {foss.).'\ 348 ' LUCERNARIAD^. (?) PociLLoroRA INTERSTINCTA (Miiller). At a meeting of the Eoyal Society of Edinburgh (Trans. March, 1846), Dr. Fleming exhibited a characteristic draw- ing of a Pocillopora presumed to be of this species, which was obtained by Dr. Hibbert in the Shetland Seas. Dr. Fleming had expected that a detailed description of this would have been published before the appearance of his "History of British Animals," in 1828. It is, however, I believe, still a desideratum. The genus is marked by the following characters : Corallum massive or sub-tree-like, with thick, imperforate walls. Visceral chambers divided by well-developed hori- zontal partitions, or floors, in successive stages. Plates rudimentary. Calices shallow, with a thick ring at the bottom of each, forming a sort of columella. lucer:n'akiad^. Contrary to my original intention, I have determined to exclude this family from my work. Their true affinities are with the Hydrozoa and Meduscp. The gelatinous tex- ture, the expanded umbrella, the ovaries in the substa::ce of the umbrella, the four-lipped mouth placed at the end of a free peduncle,* and the quadripartite arrangement, are all Medusan characters. The tentacles in marginal groups are found in Bougainvillma, and their form, — knobs at the tip of long footstalks, — agrees more with Slahheria than with Corynactis and Caryojpliyllia.

Adherent to rocks ; considerably exceeding the column. Column. Flat and wrinkled when completely contracted : rising to a tall, somewhat slender pillar, studded with low warts on its upper portion, but covered on its lower two-thirds with a tough, firmly adherent epi- dermis, the upper edge of which is free, with a ragged foliaceous margin, not foi-ming a tube. The surface of this is transversely corrugated, but not warted. The animal frequently expands in its low condition, when the flower occupies the summit of a very low cone, and is not half the diameter of the base. A slight margin, much wrinkled in semi-contraction, and forming a star of radiating furrows in closing. DisJ:. Flat or slightly concave ; outline circular. Tentacles. Arranged in five rows, viz. 6, 6, 12, 24, 48 = 96 ; short and slender, diminishing from the first row outwards ; in ordinary extension not longer than one-fourth the diameter of the disk ; generally carried arching over the margin, the tips occasionally turned up. Mouth. Elevated on a strongly marked cone. Acontia. Not emitted, even under strong irritation, while in my posses- sion. Mr. Brodrick, however, has seen them projected from the mouth. '^50 APPENDIX. Colour. Colvmn. Exposed part pellucid white, with the warts opaque white. Epidermis. Ochreous drab, slightly darker in some parts, with longi- tudinal white lines proceeding from the base, and vanishing a little way up. Central star of button formed of alternate whitish and blackish rays. Dish. Drab : each primary and secondary radius marked with two parallel lines of dark chocolate-brown ; each tertiary radius is similai-ly but more faintly marked, and the space inclosed is in these latter radii drab on their outer and white on their inner moiety, the divisions of the two colours being marked by a black spot. The space immediately bounding the foot of each primary tentacle dark brown. Tentacles. Pellucid whitish ; the lower half opaque white on the front, crossed by four transverse bars of dusky, the whole (except the lowest one) being connected by three longitudinal lines of the same colour, which impart a latticed or window-like pattern to the tentacle. Mouth. Lip white ; throat white, with black furrows. Size. Diameter of base nearly an inch, of extended column half an inch, of flower from one-third of an inch to an inch ; height one inch. LOCALITT. Lundy Island : on rocks at low water. My acquaintance with this species I owe to the courtesy of William Brodrick, Esq., of Ilfracombe, with whose name I have honoured it. He kindly sent rae a specimen in November, 1858, which had at that time been in his possession about sixteen months, having been taken with another individual in the summer of 1857. Its habit is to remain on an exposed stone, without any disposition to roam : it is generally closed by day, or if open the column is contracted ; but it elongates in darkness. It is very timid, and cannot on this account be fed : the slightest touch of the tentacles I found to be followed by an instant closing. The light of a candle, concentrated by a lens, presently causes it to shrink and contract. gausapata. Broduicu. troglodytes. ASTILEACEA. BUNODIBjE. THE RINGED DEEPLET. Bolocera eques. (Sp. nov.) Plate IX. Fig. 6. Specific Character. Tentacles wholly retractile ; white, encircled with a red ring. GENERAL DESCRIPTION. Form. JBase. Adherent, scarcely exceeding the column. Column. Cylindrical ; very changeable in shape ; very distensible ; surface covered with numerous slightly indented, close-set, longitudinal striae ; studded, on the upper two-thirds, with numerous minute warts, increasing in number to the margin : these are either prominent or level, at the pleasure of the animal, and they have the power of attaching frag- ments of extraneous matter, which, however, seems rarely exercised. Substance lax and pulpy, with thin integuments. Margin forming a thick parapet, the summit obtusely edged, and notched with close-set denticulations, which are not warts, but are the terminations of the striae. IHgk. Flat, smooth, with very delicate and inconspicuous radii ; outline expansile beyond the column. Tentacles. Sub-marginal, set in six rows: 6,6,12,24,48,48^144; short, thick, conical, but versatile in form, in contraction being slender, in distension often ovate, or when this is partial, ovate with a slender point {mucro) ; constricted at foot, and in contraction marked with longitudinal mlci, both of which are very readily obliterated ; the tip perforate. They are subequal, about an inch and a half in length, and when distended, . upwards of one-third of an inch in diameter ; are flexuous, and thrown in various directions ; are strongly adhesive ; they are perfectly and readily retractile, but in a peculiar mode ; the margin contracts, till its edges meet over the tentacles, but it never involves itself. Mouth. Occasionally protruded in form of a wide cone. Two gonidial grooves, each with its pair of tubercles, and its broad, though faintly marked, radius. Lips thickened. Stomach-wall capable of being pro- truded in great bladder-like lobes. COLOUB. Column. A rich light orange-scarlet, rather duller towards the base ; the striae marked by slightly paler lines ; the warts white, each inclosed in 352 APPENDIX. a ring a little deeper than the general hue ; the region below the warts studded with much more minute and more crowded whitish specks. Dish. Pale buff or dx'ab, unspotted ; pellucid. Tentacles. Pellucid white ; a broad scarlet ring, bounded below by a narrower one of opaque white, surrounds the middle of each tentacle. Mouth. Lip as the disk. Gonidial tubercles white. Stomach-wall marked with alternate lines of pellucid and opaque white. Size. Height of column, when distended, four inches, diameter nearly the same ; expanse of flower about seven inches. Locality. North Sea : deep water. The acquisition of tlie magnificent animal above de- scribed, for Avhich I am indebted to the kindness of Mr. D. Ferguson, of Coutham, not only enables me to augment the genus Bolocera, and at the same time the British Fauna, •with another species, but also makes me better satisfied with the establishment of such a genus. Equal in dimen- sions to B. Tuedice, and presenting much in common with that species, there are peculiarities in this specimen which compel me to consider it specifically distinct. These are tlie brilliant hue of the column, its striate surface, the thinness of the integuments, the much feebler sulcation and constriction of the tentacles, and the rings of positive colour which adorn them, together with their power of complete retractation. All these characters make the pre- sent species a decidedly nearer approximation to Tealia. Indeed, when fully expanded, so remarkable is the resem- blance in form, size, and colour, to a fine T. crassicotmis, tliat I have little doubt the reason of its having been hitherto overlooked, is that it has been passed over as that familiar species. Yet the minute warts, the (really though slightly) constricted and furrowed tentacles, and the non-retractility of the margin, determine its place in this genus. The nobleness of its tout ensemble, and especially the 1 APPENDIX. 3SS rings on its many fingers, suggested to me a specific appel- lation, in allusion to old Rome's coxcomb chivalry, whose gold rings were no less characteristic than their valour. My friend informs me that the specimen was procured on the 17th of December, 1858, in twenty-eight fathoms' water, about ten miles east of the mouth of the Tees. The fisherman who obtained it (a carefal collector) had never seen one like it, though he had been very familiar with T. crassicomis, fix)m the circumstance of some hundreds of specimens having been sent to 3£r. Teale, fi-om Redcar, when that gentleman was engaged in his important re- searches into its anatomy. It lived upwards of three weeks with its first possessor, and after that a fortnight with me. The greater portion of this latter period it passed in a large tank, where it attached itself, expanded and dilated most gorgeously, presenting a grandeur of beauty which all who beheld it could scarce sufficiently admire. But for a few days before its death it loosed the hold of its base, and began to rupture the integuments, displaying the cras- peda. Then the Stomach-wall protruded, at first in a vesi- cular manner, and then by the inordinate recession of the lip, so that the plicate and corrugated stomach occupied the whole place of the disk. Then the tentacles lost their power of distension, and resumed their flaccid and con- tracted condition, when the longitudinal sulci became again conspicuous. And so the illustrious stranger died. I subsequently received another specimen from Banfi", in every respect like the former. It survived but ten days. TuedisB. EQUES. T. crassicomis. A A 354 APPENDIX. II. SPECIES DESCRIBED AS BRITISH, BUT WHICH I AM NOT ABLE TO APPORTION TO THEIR TRUE PLACE, FROM THE LACK OF PERSONAL ACQUAINTANCE WITH THEM. Alderi (Cocks). " Body cylindrical, hyaline, smooth ; numerous grass- green longitudinal striae ; tentacles twelve, short, obtuse, with a continu- ation of the green line on the posterior surface of each. Disk and mouth crimson, the latter marked with eight spots of same colour, but much darker; edge of disk entire; suctorials minute, numerous, imbedded." Deep water, off Falmouth. Pellucida (Cocks). " Body cylindrical, smooth, opalescent ; numerous white longitudinal grooves ; suctorials minute ; tentacles short, filiform, transparent, plain ; mouth small ; disk circular, flat, crossed by opaque white lines ; edge entire." Falmouth. Yan-ellii (Cocks). " Body conoid, hyaline, with twenty-four longitu- dinal semi-opaque white striae ; suctorials numerous, minute, imbedded. Three rows of tentacles, short, obtus© (rather clavate), spotted all over with white. The ovarian filaments, &c. distinctly seen through the trans- parent tunics." Falmouth. Bella (Cocks). "Body cylindrical, hyaline, spotted with yellow; twelve longitudinal opaque white striae ; mouth bright orange-red ; two yellow patches extending from the angle on each side to the base of the tentacles ; tentacles twenty, long, filiform, dotted anteriorly, and tipped, with yellow." Falmouth. .ff^ci^te^a (Wright). "Base adherent to rock; not exceeding column. Column , smooth ; height about equal to breadth (one inch). Disk hollow, hardly equalling diameter of column. Tentacles numerous ; in five or six rows, set close to margin ; nearly equal ; very conical and short ; thickly crowded. Mouth set on a cone ; lip tumid, furrowed. Column and disk sienna-brown, or salmon colour. Tentacles light brown, with two white bars across the base, tip slightly white or translucent. Lips orange or brick-red." Berehaven, Co. Cork, N.B. The above five species seem all referrible to that group of the genus Sagartia, which I have provisionally named Thoe. Intestmalis (Fabric). " Body cylindrical, the upper half suddenly con- tracted and narrow." — " When contracted, the body seems like two broad rings, of nearly equal bi'eadth, and about half an inch in diameter ; when expanded to nearly two inches, the body consists of two cylindrical por- tions of difiereut dimensions, smooth, pellucid, yellowish ; a few longi- tudinal white streaks ; disk not expanded ; tentacles about eighteen, filiform, in two rows." (Fleming.) Shetland. APPENDIX. 355 m. ADDENDA. Sagartia bellis. The Act. Johrutoni of Mr. Cocks is a variety of this species ; two specimens have come under my notice. miniata. A friend {E. W. H. H.) thinks that the Act. elegans of Dalyell is this specie (see supra, p. 100). If so, my name must give place to liis. omata. I have taken this at Torquay. It has been also found at Mizen Head, and sent me from Banff. The markings are true to the description, and leave no doubt of its distinctness as a species. pallida. Sent me in some numbers from Banff. A consider- able colony has also been found at Torquay. cocdnea. Abundant in deep water, Torbay. parasitica. Found, at Jersey, between tide-marks. Pkellia gausapata. 1 have since seen numerous specimens ; the species is quite distinct from P. murocincta. A very large specimen has been taken from deep water in Torbay. picta. Other specimens have been sent me from Banff. The epi- dermis is very thin and deciduous ; and altogether the species seems inter- mediate between the true Pkellice and such Sagartia as cocdnea. Adamsia palliata. Some interesting facts concerning this species and its connexion with the Hermit-crab will be found in a paper of mine, " On the Transfer of Adamsia palliata from Shell to Shell," published jn the Zoologist for June, 1S59. Sphenotrochus Macandrewanus. This has occurred more abundantly than the text seems to imply. Both Dr. Cocks and Mr. Alder inform me of having seen numerous specimens, chiefly from tbe Cornish coast ; and the latter has kindly presented me with two specimens. Wrightii. Dr. "Wright has sent me a fifth specimen from the same bank as the other four, differing considerably in form from all. LophoTielia prolifera. I have omitted to mention a fine British specimen, preserved in the Museum of Newcastle ; and another mentioned by Lands- borough, from Barra, one of the Hebrides. Balanophyllia regia. Two living specimens have been dredged in Ply- mouth Sound, by Mr. T. H. Stewart of the Roy. Coll. Surg. 356 APPENDIX. IV. GEOGKAPHICAL DISTRIBUTION. In the following attempt to distribute our Sea- Anemones geographicailj, I divide the whole British Coast into ten provinces, thus (somewhat arbitrarily) defined. 1. The Shetland, including the Orkneys, and Scotland as far aa Kinnaird's Head. 2. The North Sea, including the coast from Kinnaird's Head to Spurn Head. 3. The Eastern ; from the Humber to the Thames, a fiat low shore. 4. The South-east; firom the Foreland to St. Alban's Head; chiefly chalk cliSa. 5. The Devonian; from St. Alban's to St. David's Head; a rugged rocky coast. 6. The Irish Sea, to the Mull of Cantyre, including Man, and the Irish shore. 7. The Hebridean, from Cantyre to the Orkneys. 8. The Sonth Irish, from Cai-usore Point to Mizen Head. 9. The Atlantic, from Mizen Head to Eathlin Island. 10. The Channel Islands. A glance at the table will show that the Devonian dis- trict is by far the richest in species, including two-thirds of the whole. Next in fecundity to this extreme south comes the extreme north, numbering, however, less than two- thirds of the Devonian total. The Irish Sea, the Atlantic coast of Ireland, and the Channel Isles, each claims about two-thirds of the Shetland total. The province of the North Sea holds about two-thirds of this last number ; and then come in succession the South-east, the Eastern, and South Irish, and finally the Hebridean. These numbers represent, of course, the state of our knowledge rather than the fact. I look for additions in the Devonian province, and far more in the Shetland and Hebridean, of which last I know almost nothing. The Atlantic province will doubtless be farther enriched, and that of the Channel Isles. But I do not look for many species to be added to tlie North Sea ; and few if any to the Eastern and South-eastern provinces ; — mud and chalk being essentially ungenial to Sea-anemones.
