[From the REPORT of the BRITISH ASSOCIATION for the ADVANCEMENT of SCIENCE for 1868.] LAST REPORT ON DREDGING AMONG THE SHETLAND ISLES. BY J. GWYN JEFFREYS, F.R.S., REV. A. MERLE NORMAN, M.A., W.C. M'INTOSH, M.D, F.L.S., AND EDWARD WALLER. PRINTED BY TAYLOK AND PRANCIS, KED LlOX COTJET, FLEET STREET. BiOLOGt RA a THIS was my eighth expedition to the northern extremity of our seas, and occupied the whole of the summer. It was not so successful as those in some previous years, owing to the stormy state of the weather. While my friends in England, Wales, Ireland, and Scotland were enjoying calm sunshine, our climate was exactly the reverse ; and the persevering course of the wind (from north-west to south-west) prevented our doing much at sea. This part of the North Atlantic is notoriously subject to broken weather, it being the point where the warm air induced by the Gulf-stream and westerly winds meets the cold air brought down by the arctic current. The fauna of the Shetland waters, however, is by no means exhausted. Every expedition has produced novelties, not only in the Mollusca, but in all other depart- ments of marine zoology. On the present occasion I obtained, at a depth of 120 fathoms, a living specimen and a larger dead one of a fine species of Pleurotoma, P. carinata of Bivona. It was originally described as a Calabrian fossil ; Jan and Bel- lardi have given it from the Upper Tertiaries of North Italy, the former un- der the name of Fvsu-s modiolus ; and Searles Wood records a single specimen ON DREDGING AMONG THE^'sil Sr?L^ND iSLlsS.^ ' 233 having- been found in the Coralline arjd another i& the^Ee*el :Cija*..J, Professor Sars and Mr. M' Andrew dredged a few "sf>eciiienV off ^Ke^c6a:&t& -of ^Norway ; and the former gave some interesting particulars of the animal, which I have been able to confirm by my own observation. Although allied to P. nivalis, and found in the same locality, it has distinct eyes placed on rather prominent stalks or ommatophores, whereas P. nivalis has no eyes nor any trace of eye-stalks. On this account Sars proposed the generic name Tt/phlo- mangelia for the latter species ; but it must be borne in mind that Eulima stenostoma is also eyeless, and yet is closely related to its congeners and com- panions, all of which have very conspicuous eyes. It is a somewhat remark- able coincidence that the shell of E. stenostoma resembles a large Achatina adcula, which is in the same category as regards these so-called organs of sight. The shells of P. carinata and P. nivalis are easily distinguishable. Among the rarer and more noteworthy mollusks procured this year were the following : — Montacuta tumidula, St. Magnus Bay and near Fetlar. Described by me from the Hebrides in the Reports of the Association for 18.66. M. donacina, S. Wood. A single valve from deep water in St. Magnus Bay. Another valve had been dredged by me at Falmouth in 1839. It is a rare Coralline Crag fossil. Its nearest ally is M. substriata. Utriculus globosus, Loven. A small living specimen occurred this year also in St. Magnus Bay. U. expansus, Jeffr. A few young specimens again in St. Magnus Bay. Odostomia Warreni, Thompson. Never having seen this shell in a fresh. and perfect state, I considered it (Brit. Conch, iv. p. 143) a variety of 0. obliqua. But the discovery of live specimens in St. Magnus Bay and near Fetlar enables me to separate the two as distinct species. 0. Warreni has a shorter spire and more swollen whorls than 0. obliqua, the suture is deeper, the striaa are much stronger at the base of the shell, the whole surface is covered with most delicate and close-set microscopic spiral lines, and the umbilicus is well developed and deep. The animal of 0. Warreni has a peculiar foot ; this is not plain and rounded at its extremity, as in 0. obliqua, but is deeply bilobed or forked like the tail of a swallow. No other species of Odostomia, so far as I am aware, has a similar foot. One individual spun a fine gluti- nous thread from the middle of the foot, and kept itself suspended for some time from the surface of the water, with the point of the shell downwards. I found a dead specimen of 0. obliqua on the same ground with 0. Warreni. 0. umbilicaris, Malm. A young specimen from St. Magnus Bay, nearly globular, and thus exhibiting the same distinctive characters as the adult. Siphonodentalium Lofotense and Cadulus (or Loxoporus} subfusiformis were again found, the former being more widely distributed. Both inhabit the Mediterranean ; and the latter is a Sicilian and Viennese fossil. I had an excellent opportunity of observing them alive and in active motion. The thread-like and extensile organs by which the Solenoconchia seize their prey are unlike the tentacles of any Gastropod, and their function is quite dif- ferent. I would call these organs captacula, an appropriate word and not less classically formed than tentacula. Leda pernula was dredged, as before, in St. Magnus Bay ; but with it was a dead and apparently semifossil valve of Tellina calcaria. I must therefore hesitate in considering the one more than the other recent or an inhabitant of the British seas at the present time. Perhaps Lamellaria prodita, Lovcn, may be added to the list; but unfor- tunately the specimen was handled too roughly, and the shell was crushed to ' 234 • ; ; ;'•. \ / : pieces. Its, e«J;r^*<^ri#F£ eize; (considerably more than an inch in length) and the Jeg^^|](1^:fit^oiti,i3).at.VMclr"it was dredged deserve notice. Being in the south of Europe last winter I had an opportunity of examin- ing Mediterranean and Adriatic shells ; and the result greatly surprised as well as interested me. The dredgings of Oapt. Acton (the Commandant of the Italian navy) in the Gulf of Naples, and the extensive collections of Dr. Tiberi at Portici, General Stefanis at Naples, Herr Weinkauf from Algeria, and of Dr. Brusina at Zara, especially yielded a vast quantity of new material for a comparison of the marine testacea of the north and south of Europe. Many of the species having been described (some insufficiently) under dif- ferent names, the difficulty of identification is considerable ; but there is no doubt that a remarkable concordance exists, and to a great extent, between the mollusca which inhabit the deeper parts of the Atlantic and Mediterranean seas from 62° to 36° N. lat. The littoral kinds diifer much more — a cir- cumstance which may have been occasioned by climatal conditions. To ex- emplify the former proposition I subjoin a list of 76 species, usually considered northern, which are common to the North Sea and the Mediterranean, with their principal synonyms.

I have carefully read again Forbes's elaborate essay " On the Connexion between the distribution of the existing Fauna and Flora of the British Isles, and the Geological changes which have affected their area, especially during the epoch of the Northern Drift" (Memoirs of the Geological Survey of Great Britain, vol. i. 18.46) ; but I cannot find in it a satisfactory solution of the question. He, indeed, men- tions the continuance of some " arctic " species in the British seas, the rest having " retired for ever," and that certain other species which he called " Boreal or Celtic " occurred in a fossil state in Sicily ; and he states (p. 390) that " in the deepest of the regions of depth in the JEgean " the same repre- sentation of a northern fauna as exists in our own seas is maintained, " partly by identical and partly by representative forms." The instances he gives do not support such a view ; and I am not a believer in " representative forms." He evidently was not aware of the fact that boreal (not arctic) species still live in the Mediterranean. I, however, fully agree with him that at some former period (which he designates " the newer pliocene epoch ") there was an open communication between the Atlantic (according to him the " North Seas") and the Mediterranean, by which the fauna became diffused. I should be inclined to place the Atlantic point of communication at Bordeaux, and that of the Mediterranean at Narbonne, in the line of the Languedoc 238 REPORT— 1868. Canal, which extends from one coast to the other, and is very little ahove the present level of the sea. This communication must have been very wide ; and it remained open during the glacial epoch, which affected not only the north of Europe, but also Naples, Sicily, and probably Rhodes. Dr. Tiberi showed me a fine valve of Pecten Islandicus which had lately been fished up in the Gulf of Naples at a depth of 50 fathoms, and with it a valve of P. opercularis quite as large as northern specimens ; both the valves were in a semifossil state, and the former was covered with the same Greenland species of Spirorbis (S. cancellatus, Eabr.) as I noticed on valves of P. Islandicus dredged in the Shetland seas at depths varying from 75 to 170 fathoms. Sir Charles Lyell has not adverted, in the last edition of his ' Principles of Geology,' to the remarkable occurrence of such glacial fossils in the Shetland sea-bed, to which I called the attention of geologists in my former Reports as well as in the second volume of * British Conehology,' p. 58 ; and he seems to have overlooked the observations of Philippi and Seguenza on the fossils of Calabria and Sicily, when he stated (Princ. Geol. i. p. 298) that " deposits filled with arctic species of marine shells are to be seen in full force on the North American continent ten or more degrees further south than in Europe." Possibly he was misled by one of Forbes's conclusions (Rep. Geol. Surv. p. 402), that " no glacial beds are known in Southern Europe." This, however, was more than twenty years ago. I have myself identified from the Calabrian and Sicilian deposits several high-northern shells (e. g. Tere- bratula cranium, T. septata, Lima excavata, Mytilm modiolus, Ci/prina Islan- dica, Mya truncata, var. Uddevallensis, Saxicava Norvegica, Puncturella Noa- china, Emarginula crassa, Buccinum undatwn, and Natica affinis or clausal), and from the Rhodian deposits Terebratula septata and Lima Sarsii. My old companion, Mr. Waller, picked up on the beach in a small bay on the west coast of Shetland a shell of Spirula australis. It is a tropical Cephalopod, and is not unfrequently thrown up by the waves on the southern and western shores of England, Wales, and Ireland, together with exotic species of Teredo, lanthina, and Hyalcea brought from southern latitudes. Dr. Morch informs me that several shells of the Spinda have this year been found in the Earoe Isles. The transport of such tropical productions to northern latitudes has been usually attributed to the Gulf-stream. It now, however, appears more probable that this is the consequence, not of the direct action and course of the Gulf-stream, but of the prevalence of westerly and south-westerly winds, which waft onwards to northern latitudes, in a north- erly and north-easterly direction, the floating objects carried .to a certain distance by the Gulf-stream. The direct course of the Gulf-stream has not been observed further north than about 45° N. lat. ; from that point it would seem to dwindle into a north-easterly surface drift. A chart will shortly be published by the Admiralty in explanation of this view of the case ; and the following papers on the subject ought to be consulted by physical geographers : — Dr. Stark " On the Temperature of the Sea around the coasts of Scotland during the years 1857 and 1858, and the bearing of the facts on the theory that the mild climate of Great Britain during winter is dependent on the Gulf-stream " (Trans. R. S. Edin. 1859), and Capt. Thomas's tables and re- marks in Mr. Alex. Buchan's Report " On the Temperature of the Sea on the Coast of Scotland" (Journ. Scottish Meteor. Soc. Oct. 1865).

No really satisfactory comparison can be made between the number of animals here reported on as inhabiting the Shetland Sea with those found on other portions of our coast. Unfortunately very little attention has hitherto been paid to any, except the larger and more conspicuous forms belonging to these classes. In order, however, that this comparison may be carried out as far as at present practicable, I give the following summaries of the most fully worked up local lists that I am acquainted with.

The only local List of Sponges is one recently published by Mr. E. Parfitt, " On the Marine and Freshwater Sponges of Devonshire " (Trans. Devonshire Association for the Advancement of Science, Literature, and Art, 1868) ; it includes forty-nine marine species, while the Shetland species observed by us are eighty- three. Only eighteen of these species are as yet known to be common to these two extremities of our islands. III. Species added to the British Fauna during the recent Dredging. The new species which have during the past six years been discovered in Shetland have from time to time been published through various channels, a large proportion of them having been placed in the hands of those naturalists who were engaged in bringing out works on the several branches of marine zoology. The following list of 156 species is therefore given here in order to show at a glance the additions to our fauna which have directly resulted from the investigations of the Dredging Committee.

Mediterranean Species which occur in Shetland, but have not been found at intermediate localities. . Two large and conspicuous animals, Portunus tuberculatus, Roux, and Spatangus meridionalis, Risso, have been found abundantly in these dredgings at a depth from eighty to one hundred and forty fathoms. They are well known in the south of Europe, but were supposed up to the time of their discovery in Shetland not to occur north of the Mediterranean. It is not •unlikely that Pagurus tricarinatus, Norman, will also prove to be a deep- water Mediterranean form. All deep-water dredging seems to establish this fact more clearly, that deep-water species have a much more extended geo- graphical range than shallow- water and littoral forms. These Mediterranean species must have made their way northwards in the abyss of the sea round the western coast of Ireland, in which locality they will doubtless at some future day be found. The classes on which it is my lot to report have been so much neglected, and our knowledge therefore of their distribution is at present so extremely limited, that it is at present impossible to draw any satisfactory conclusions as to their range ; but I feel satisfied that when hereafter fuller and more accurate investigation shall have been carried on both in the Mediterranean and our own coasts, not only will the number of species common to the two extremities of Europe be found to be much greater than is now generally supposed, but also that a very large proportion of such species will prove to be forms which will be met with in the depths of the Mediterranean and of the seas to the west and north of our country, but which will be found to be absent from the channels which intersect and the shallower water which immediately surrounds our islands. Meanwhile the occurrence of Portunus tuberculatus and Spatangus meridionalis is of excessive interest, as such fine and handsome species could not have been well over- looked, or have failed to attract attention in any portion of the sea which has been at all efficiently dredged*. The contents of the three Tables (IV., V., and VI.) added together give the * The following northern Mollusca have been identified by Mr. Jeffreys from the Mediterranean, but are not known elsewhere south of the north of Scotland or Shetland Sea: — Pecten aratus, P. vitreus, Lima Sarsii, Leda pygmaa, Scissurella crispata, Aclis Walleri, Cerithium metula, &c. ; the occurrence also of the following in the Mediterranean is yery unexpected : — Terebratula caput-serpentis, Crania anomala, Pecten septemradiatus, Axinus Croulinensis, Chiton Hanleyi, Propilidium ancylo'ides, Rissoa abyssicola, Scalaria Trevelyana, Odostomla Scillce, Sulla utriculus, &c.

VIII. Species peculiarly characteristic of the Fauna of the Outer Haaf. The following list gives the species which impart a peculiar character to the fauna of the deep sea of Shetland, known as the " Outer Haaf," in a depth of 80-170 fathoms. The Molluscan inhabitants of this region are highly interesting, but it is not within my province here to speak of them. Crustacea are few in numbers, Portunus tuberculatus, Munida, two or three species of Crangon, Pandalus brevirostris, Cumacea, Ampelisca, and Epimeria tricristata .being the most abundant. Echinodermata are abundant, and cer- tain species sometimes in the most extraordinary profusion. Polyzoa and Sponges are very abundant, but of Coelenterata there are but few species; those species which do occur belong, for the most part, to the Zoantharia. Caryophyllia Smithii v.ar. borealis is found inhabiting these depths in marvellous abundance ; Zoanthus anguicoma is common, creeping over Sponges from the greatest depths, and an occasional Bulocera eques or Tuedicv, or a noble Ulocyathus arcticus presents itself to our admiring gaze. Yery few Tunicata occur below seventy fathoms. The names which follow are of the most abundant or, at any rate, more conspicuous species ; the list might, had I so wished, have been greatly extended.

There is no text-book which embraces all the orders of Crustacea, and which can be followed in this class. Even for the separate orders few guides can be found that are at all up to the standard of the present state of our knowledge of the British forms. For the Podophthalmia I have in ON THE SHETLAND CRUSTACEA, TUNICATA, ETC. 263 the main followed the arrangement of Bell's ' British Stalk-eyed Crustacea ; ' but the law of priority in nomenclature is not sufficiently attended to in that work, and it is necessary therefore, in numerous instances, to substitute the earlier names under which the species was described ; and moreover so greatly has the study of even these larger and better known Crustacea advanced during the last few years that, of the seventy-eight species of this subclass here recorded, no less than thirty-one are undescribed in the work referred to. In the Amphipoda and Isopoda I have followed the general arrangement of the recently published work upon ' The British Ses- sile-eyed Crustacea,' by Messrs. Bate and Westwood. In the Ostracoda, two admirable guides exist in Herr G. rO. Sars's ' Oversigt af Norges marine Ostracoder, 1865,' and Mr. G. S. Brady's " Monograph of the recent British Ostracoda" (Trans. Linn. Soc. vol. xxvi. 1868). In the Copepoda, I have derived great assistance from Dr. Claus's ' Die frei-lebenden Copepoden,' and from the smaller memoirs by the same author. Descriptions of most of the remaining species in the following catalogue must be sought in the various papers, monographs, and works which will be found referred to in the text. Order BRACHYURA.

This Anonyx, the specimens agreeing in all respects with Spitzber- gen examples, received from Prof. Loven, except that they are not more than a quarter the size, was procured on the Out Skerries Middle Haaf, in 1861. It occurred in hundreds upon a fish which had been brought up dead on a fisherman's long line. It would appear to be one of the scavengers of the seas ; for Goes also writes of it, " Ad Spetsbergiam inter algas, prsesertim fundo arenoso et argillaceo profunditate orgyarum trium usque ad sexaginta copia stupenda, eo ut, si perite ac prudenter in captura versaris, hos pelagi voracissimos vespellones molibus milliariis cadavere avium vel phocarum brevi e fundo elicere potes." The contour of this Anonyx is peculiarly rounded and smooth, by which character it may, without microscopic examination of the limbs, be distinguished from longipes. It is now first added to our fauna. tumidus, Kroyer, Naturhistorisk Tidsskr. Anden Rsekke, Bd. ii. p. 16 ; Voyage en Scandinavie, pi. xvi. fig. 2 ; Bruzelius, Skand. Amphip.

Common in shallow water in all the Voes, among Laminariae. The female differs widely from the male in the structure of the first gnathopods. In these organs the meros is not abnormal (as in male), the wrist subquadrate, slightly widening distally, posteriorly fringed with setae, and a tuft of setae on the side; propodos broadly ovate, with tufts of setae on both margins ; palm undefined, except by the presence of a spine with which the finger when closed impinges ; finger strong, half length of hand, serrate on the inner margin, with a small cilium in each serration. I believe, judging from specimens named for me by Mr. Bate, and the figure and description which represent an animal " sparingly scattered with black dots," that the Microdeuteropus anomalus of Bate and Westwood, p. 293 (not of RatJilce), is the female of this species ; but the females of this and of the next species are so very much alike as to be almost undistinguishable. Microdeuteropus anomalus (Eathke). Gammarus anomalus, Nova Acta Leop. 1843, p. 63, pi. iv. fig. 7, =Aulonoe anomala, Bruzelius, Skand. Amphip.

The figure in the ' Brit. Sessile-eyed Crustacea ' of Microdeutopus gryl- lotalpa represents the young male of this species ; in the adult male the strong tooth-like process of the carpus of the first gnathopods is itself furnished with a secondary (lateral) tooth ; and the hand is much nar- rower at the base than at the apex, the posterior margin being concave ; this state is well represented by Bruzelius, pi. i. fig. 4, d. The female is extremely like that of the last species, and is sufficiently well repre- sented at p. 293, Brit. Sessile-eyed Crust. ; though, for reasons already stated, I incline to think that that figure really is drawn from the female of Aora. This species is most certainly not the Microdeutopus c/ryllo- talpa of Costa (Ricerchc sni Crostacei Amfip. del regno di JSTapoli, p. 231, pi. iv. fig. 10), which, from the four teeth of the carpus, seems to be closely allied to, if not identical with the Autonoe fjrandimana of Bruzelius.

The male differs greatly in the structure of the first gnathopods ; these have the carpus very large, ovate, and very broad, infero-posteally produced into a simple tooth-like process, which reaches forward to not quite half the length of the hand ; hand as wide or wider at the extremity than at the base ; posterior margin convex, undulated ; finger internally serrated, serrations very few, three to five only. Eare in Shetland; 70-80 fathoms, Outer Haaf. Websteri, Bate. Bate and "Westwood's figure represents the male. Specimens from Bressay Sound have a deep brown broad band across the pereion ; and in company with them were other specimens similarly marked, and agreeing in general characters, but with gnathopods of totally different structure. These I take to be the females. They so closely resemble the females of Aora gracilis and Microdeuteropus ano- malus that one description would suffice for all. Also taken among Laminariae in St. Magnus Bay and on the Haaf. I question whether there are sufiicient grounds for separating the genus Aora from Micro- deuteropus. We have seen that the females of two are almost undis- tinguishable ; and if Aora be divided from Microdeuteropus because the tooth-like projection proceeds from the meros and not the carpus, M. Websterii must in justice have a similar distinction conferred upon it, because in that species the tooth-like projection does not spring from either meros or carpus, but from the hand. Genus MEGAMPHOPTJS, n. g.* Antennae slender (imperfect), the insertion of the lower so much behind that of the upper that the end of the third joint of the peduncle is only on a level with the end of the head. First segment of pereion produced forwards and downwards on each side into a remarkable horn-shaped process. Both pair of gnathopods greatly developed, of equal size, and subchelate. First three pereiopods short, last two much longer. Telson tubular. MegampTiopus cornutus, n. sp. (species typica). Head produced greatly be- yond the origin of the inferior antennae ; eye round, black, immediately behind the base of the superior antennas, and thus greatly in advance of the origin of inferior antennae. Superior antennae slender, first joint very much thicker than but only about half the length of second, sub- equal in length to last ; (there is perhaps a very minute secondary appendage, one-jointed, not half length of first joint of filament ; but as the filaments of the antennae are imperfect, I cannot speak with cer- tainty on the point, all I am confident of is that if there is a secondary appendage it is excessively minute). Inferior antennae with the distal extremity of the third joint only reaching the extremity of the head ; fourth joint twice as long as third, and last joint rather longer than fourth; filament subequal in length to last joint of peduncle, com- posed of eight long articulations. First segment of pereion produced forward and downwards into a curious horn-like process, the form of the side of the segment and its process reminding one strongly of the side of a wheelbarrow and its handle. Pirst gnathopods greatly deve- loped ; basos long and slender, two following joints short ; carpus long, nearly four times as long as broad, anterior margin straight, naked, posterior margin gently convex, with little tufts of setae, distally pro- duced into a short blunt process which curves backwards ; propodos * Meyas, great ; «u0w, both ; TTOVS, a foot. ON THE SHETLAND CRUSTACEA, TUNICATA, ETC. 283 not quite so long as carpus, ovate ; palm continuous with the hand, with a row of about eight strong spines; finger gently curved, shutting closely against the hand, which it nearly equals in length. Second gnathopods in general character very like the first, but the propodos somewhat broader and longer (as long as carpus), with two or three longitudinal rows of hairs in place of the spines of the first pair, and the finger only about half its length. Basos of the anterior pairs of pereiopods of somewhat twisted form, the front margin armed with several (5-6) strong spines. All the uropods subequal in length, bear- ing the same general characters as in the genus Microdeuteropus. Telson tubular. Length a third of an inch. A single specimen pro- cured in 1863. Protomedeia pectinata, n. sp. Superior antennae with second joint of peduncle subequal in length to but much more slender than first, last joint two- thirds length of second ; filament slightly longer than peduncle, con- sisting of about ten long articulations ; secondary appendage two-jointed, scarcely longer than first articulation of filament. Inferior antenna3 subpediform, short; filament not longer than last joint of peduncle. First gnathopods having basos fringed anteriorly with a few scattered long seta3; ischium having a postero-distal dense tuft of long seta3; meros, carpus, and propodos all posteriorly thickly clothed with rather long setae, the last two subequal in length, the propodos oblong, sub- parallel sided, twice as long as broad, distally truncate ; finger strong, much longer than the truncated extremity of propodos, not internally serrate (as in $ of Microdeuteropus versiculatus, which this species re- sembles in general structure of first gnathopods), but furnished with a single large spine on the inner edge near the apex. Second gnathopods having basos long (equal in length to four succeeding joints), posteriorly straight, anteriorly convex, and furnished with two rows (one on edge and the other a little within it) of very long slender seta3, arranged in a comb-like manner ; ischium and meros narrower than carpus ; carpus narrow, only slightly widening distally ; propodos subequal in length to carpus, lanceolate, tapering from base to distal extremity, both margins fringed with long setse, those of the anterior side the longer ; finger long, narrow, of equal thickness throughout, more than half as long as propodos, not unguiculate, nor capable of being bent back upon the pro- podos; the blunt distal extremity terminated by two or three seta9. First pereiopods not having the meros anteriorly produced ; finger very long and slender, subequal to propodos, and much longer than carpus. Last pereiopods with hinder margin of basos not serrated, furnished with a row of distant seta3, which take their origin from some little distance within the margin. Telson and uropods closely resembling in structure those of the species of Microdeuteropus. A single specimen (a female ?) dredged in St. Magnus Bay, 1867. - (?) Whitei, Bate. Five to eight miles off the island of Balta, 40-50 fathoms, and in Balta Sound, about 7 fathoms. This species is certainly no Protomedeia ; the squamate, double telson separates it from that genus. I believe it to be the female of Lillje- borgia Shetlandica ; at any rate the male of the present species most closely resembles the drawing and description of that species in all respects except that the basos of the last pereiopods is not so distinctly serrated as figured. Unfortunately my type specimens of Lillyeboryia Shetlandica have been mislaid ; and for the present it will be better to 284 REPORT— 1868. keep the species apart, notwithstanding a very strong suspicion that they will hereafter prove to be the same. Protomedeia hirsutimana, Bate. Unst Haaf, 90-100 fathoms, and 5-8 miles east of Balta, 40-50 fathoms. The posterior portion of the body, un- known to Mr. Bate, has some very remarkable characters. The last three pereiopods successively increase in length, the apex of the palm is truncate, the finger is short, strong, and bifid, and takes its origin from one-half only of the end of the propodos, while from the other half spring several long, spine-like seise. First and second uropods sub- equal in length ; the first with the branches furnished with the usually formed spines ; the second of most unusual and remarkable character, excessively strong and massive, the branches furnished on their upper edge with two rows of immensely strong, but very short, stout, blunt spines ; last uropods shorter than preceding pairs : branches subequal to peduncle, each bearing about three strong spines and terminating in a tuft of seta3. Telson tubular. The extraordinarily massive and immensely strong spined second uropods have no parallel, as far as I am aware, among the known species of Amphipoda. Bafhyporeia pilosa, Lindstrom. Forty miles east of Out Skerries, 70-90 fathoms ; 5-8 miles east of Balta, 40-50 fathoms ; Balta Sound, 5-7 fathoms. Robertsoni, Bate. " Two specimens have been dredged by our friend Mr. J. Gwyn Jeffreys in the Shetlands " (Bate and Westwood) . Melita obtusata (Montagu) = Melita proximo., Bate & Westw. Brit. Sessile- eyed Crust, p. 344 (the more common variety of male), — Megamcera Alderi, Bate & Westwood, p. 407 (the female). St. Magnus Bay, off Balta, Outer Haaf, &c. Melita proximo, is the common form of the male, and Meg ameer a Alderi is the female. The variety of the male with a central dorsal tooth on the second and third segments of pleon is far less common, and is the typical Melita obtusata (Mont.) ; one specimen of this variety has occurred to me in Shetland, and other specimens show scarcely visible rudimentary teeth on those segments. Mcera longimana (Leach) = Megamcera longimana, Bate & Westw., the male = Megamcera othonis, Bate & Westw., the female.

Among Tubularia indivisa, in Halse Hellyer, Bur- rafirth; among Laminariae, Hillswick; Out Skerries Harbour, 3-5 fathoms ; and one mile north of Whalsey Lighthouse, in 40 fathoms. I question whether B. and W.'s figure of the entire animal represents, as they suppose, the immature state of this Podocerus ; but the figures of the gnathopod and superior antennae illustrate the strongly marked features of the mature P. capillatus. falcatus (Montagu). Out Skerries Harbour, 3-5 fathoms; Burrafirth caves ; Bressay and Balta Sounds. pelagicus (Leach). With the last, of which I believe it to be the female. I have never met with a male pelagicus, nor a female falcatus. The two forms occur in company, and the structural differences seem confined to the exact form of the hand of the gnathopods, organs which seem gene- rally to differ among the Amphipoda according to the sex. Cerapus abditus, Templeton. Balta Sound and Hillswick. • difformis (M. -Edwards) <$ ,=Dercothoepunctatus, M. -Edwards, $ . Vid- lom Voe ; off Balta and St. Magnus Bay. Dercothoe punctatus is unques- tionably the female of C. difformis, not of C. abditus. The form which B. and W. figure as the female of C. difformis is probably a variety of the male. Siplioncecetes typicus, Kroyer. The first British specimen, dredged in 1861, sixty miles east of Shetland, in 70-90 fathoms ; also 5-8 miles east of Balta, 40-50 fathoms, 1867. Na'nia rimapalmata, Bate. St. Magnus Bay, and 5-8 miles east of Balta ; 40 miles east of Whalsey Lighthouse, 70-90 fathoms. • excavata, Bate. Off Balta, and in St. Magnus Bay. Uyrtophium armatum, n. sp. Body strongly tuberculated ; head with a central tubercle ; first segment of pereion with two tubercles, one behind the other, all the remaining segments of pereion and first two of pleon having a transversely placed pair of tubercles, one on each side of the back, the tubercles of the last segment of pereion and of the first two of pleon much larger than the others. Eirst gnathopods with wrist and hand subequal in length, the former wider at the base than at the distal extremity, with many setae on sides and posterior margin, but none on the anterior margin ; the latter subtriangular, widest in the middle (at the commencement of the palm), sloping thence equally to the base and to the origin of the finger, anterior margin gently convex, dorsal margin, sides, and palm bearing many setae ; finger not quite as long as the palm, strong, with a slightly bifid extremity. Second gnathopods with basos antero-distally produced into a strong spine-formed process ; ischium, rneros, and carpus all very short, and subequal in length, the meros on the posterior side running out into a very large spine-formed lobe; hand very large, obovate, very broad ; palm half its length, bearing a few small setae ; finger very large and strong, well arched, inner margin simple. Pereiopods with the basos not at all expanded, nor wider than 286 BEPORT— 1868. the following joints; nails strong, scimitar-shaped, the entire limbs almost naked (having only a very few short setas upon them) . Length one-fifth of an inch. A single female dredged in 100-110 fathoms, twenty-five miles N. by "W. from Burrafirth Lighthouse, in 1867. The specimen is imperfect, having lost antenna), &c. The sixth and seventh segments of the pereion appear to be coalesced. It approaches Lcetma- tophilus tuberculatus of Bruzelius, but is much more strongly tubercu- lated, and the gnathopods of different structure, the first smaller, the second larger, the hand broader, and the basos spined. Unciola planipes, Norman, Nat. Hist. Trans, of Northumberland and Durham, vol. i. (1865) p. 14, pi. vii. figs. 9-13. Balta Sound, 5-7 fathoms. Many specimens. Corophium longicorne (Eabricius). " Some specimens, which we take to be the young of this species, we find in the collection sent to us by the Rev. A. M. Norman, taken in from two to five fathoms, in Outer Sker- ries Harbour, Shetlands" (B. and W.). crassicorne, Bruzelius, the male, = Corophium Bonellii, Bate & AVestw. Brit. Sessile-eyed Crust, vol. i. p. 497 (? Corophium Bonellii, M.-Ed- wards), the female. Very abundant, in 2-5 fathoms, Out Skerries Har- bour. The C. Bonellii of Bate and Westwood is unquestionably the female of C. crassicorne ; the female of C. longicorne (which B. and "W. thought C. Bonellii might be) is quite different. tenuicorne, n. sp. Two females, dredged in St. Magnus Bay, resem- bling in general characters the same sex of longicorne and crassi- corne, but distinguished as follows. Superior antennas slender, longer than the inferior ; first joint cylindrical (not expanded), peduncle with two or three spines on inner edge ; second joint longer than first, slender, third not half as long as second; filament composed of six long joints, the terminal one bearing a number of long tentaculiform setas. Inferior antennas with penultimate joint of peduncle cylindrical (not expanded), inner edge with two or three articulated spines about the centre, and a single long, slender, articulated spine at the distal termination; last joint about two-thirds as long as the penultimate, bearing two spines on the middle of the inner side ; filament unusually pediform, consisting of • a long, stout articulation (more than half as long as the last joint of the peduncle) and a strong terminal nail. Finger of gnathopods biclentate at the apex. Nail of pcreiopods longer than carpus and propodos com- bined. First and second uropods terminating in long slender spines, which are more than half as long as their rami ; last uropods having the branch longer than its peduncle, not wide, three times as long as broad, tipped with long setse, but having no setas on the inner and outer mar- gins. Length about one-fifth of an inch. The specimens procured are females laden with eggs ; the male is unknown to me. Hyperia galba (Montagu), Bate & West. Brit.

I believe that the above four so-called species are the different sexes and periods of growth of one. The specific points will be found in the structure of the gnathopods (as accurately described by B. and W. under Lestrigonus exulans} and of the uropods, which have the rami of all three ON THE SHETLAND CRUSTACEA, TUNICATA, ETC. 287 pairs wide in the middle but narrowed at the base, and mucronate at the terminations ; the inner margins of the raini of the first pair, and the inner margin of the outer ramus, and both margins of the inner ramus of the last two pairs, are elegantly serrated. Hyperia oblivia, Kroyer, Gronlands Amphipoder, p. 298, pi. iv. fig. 19 (but not H. oblivia, Bate & Westw. vol. ii. p. 16). Filaments of both antennae consisting of only a single joint. First gnathopods with wrist and hand subequal, the former spined posteriorly, not at all produced distally; hand slightly tapering, palm serrate distally, finger two-thirds as long- as hand. Second gnathopods with meros sheath-formed, tipped with spine-like setae and overlapping carpus ; carpus greatly produced dis- tally into a lobe which reaches nearly to the extremity of the hand ; finger straight, two-thirds as long as hand. Pereiopoda, last three pair much longer and more slender than in H. galba ; carpus and propodos both very long, the latter the longer, both with small distant spines on the hinder margin, and the whole hinder edge of the propodos micro- scopically pectinate. Eami of all the uropods lanceolate (not widening in the middle), gradually tapering to the end (not mucronate as in If. galba) ; the general serrated character of the margins of the rami. agrees with H. galba, except that the external margin of the inner ramus of the second pair is not serrated. The male differs from the female, as in the last two species, in having the antennae very long and slender. A female from an Aurelia, and males taken living free in the towing- net. It has also been sent to me by Mr. Edward from Banff; and Mr. G. S. Brady has procured both sexes in some numbers off the mouth of the Tees in the towing-net. Bate and Westwood's " H. oblivia" which has not the propodos of the gnathopods at all produced, cannot be Kroyer's species nor that here described*. Goes takes Kroyer's Lestrigonus exulans to be the male of H. oblivia ; and as far as the description and figures go, it may be the male either of that or of H. galba ; but the short pereiopoda of L. exulans and L. Kinaliani of Bate will not agree with the male of H. oblivia. Metoecus medusarum, Krb'yer, Gronlands Amphip. p. 288, pi. iii. fig. 15 (not Hyperia medusarum. Bate, Cat. Amphip. Crust. Brit. Mus. p. 295). Female antennae very short; filaments of both pair one-jointed. Both gna- thopods nearly alike, short, distinctly chelate, and of peculiar structure ; meros produced into a large sleeve-shaped process, postero-distally tipped with setce, which fits round the basal portion of the carpus ; carpus postero-distally produced into a large lobe, which extends as far as the extremity of the propodos, with which and with the finger it forms a regular chelate organ ; propodos slightly tapering from the base to the extremity ; its inner margin, the inner margin of the small finger, and the inner margin of the thumb-used lobe of the carpus all denticulately serrated ; hand and wrist wholly free from hairs or spines. Pereiopods of moderate length; carpus and propodos subequal, their inner margins microscopically pectinate. All the uropods having the inner margin of outer ramus, and both margins of inner ramus serrated. The male differs from the female in having very long antennae. A female found in a Medusa in Shetland in 1867 ; and a male has been sent to me by Mr. T. Edward from Banif. The Hyperia medusarum of Bate bears no resemblance to Kroyer's * I would propose for it the name of H. gracilipes. 288 REPORT— 1868. species, to which it is referred, the gnathopods being of entirely dif- ferent structure.

Dorsal view long-elliptic, very tumid ; breadth equal to one-half of length, of nearly equal width throughout, and remarkably regularly rounded at the broad extremities. Length ^-V inch. This species has much more the aspect of a Cytlieridea than of a Cytliere, but the hinge-margin is not toothed. In the genus Cyfhere it should perhaps come next to G. albomaculata.

St. Magnus Bay ; also Plymouth. navicida, n. sp. Carapace having dorsal margin perfectly straight in the central portion, then sloping both before and behind very obliquely, with a well-marked very obtuse angle ; ventral margin also straight, the straight portion much longer than that of dorsal margin, with two ON THE SHETLAND CRUSTACEA, TUNICATA, ETC. 293 small nodulous processes, one just opposite the commencement of each dorsal slope, anteally scarcely rising at all to join the dorsal slope which at that extremity meets the ventral line very much below the centre ; posteally sloping upwards obliquely, and meeting the dorsal margin at a rounded point a little below the middle of that extremity ; surface perfectly smooth and glabrous. Ventral aspect boat-shaped, the resemblance most striking, centrally depressed at the juncture of the valves ; bows moderately sharp, of good breadth of beam, sculptured with raised thread-like concentric lines representing the timbers, while the small nodulous processes (mentioned in describing the lateral view) will stand for the thole-pins ; the dorsal and end views bear out the allusion, the former representing a boat viewed from below, with a well-marked keel, and the latter being triangular with gently rounded sides. Length about -fa inch. St. Magnus Bay, 30-60 fathoms, 1867. Genus SABSIELLA*, n. g. Carapace subrotund, with a rostrate posterior (?) projection, much com- pressed ; surface of valves very rough, with greatly elevated rib-like sculp- ture ; ventral margin quite flat in its central portion. These are certainly not satisfactory generic characters, being so in- complete, but having only one good specimen I am unwilling needlessly to run the risk of destroying it in the attempt to separate the valves, and therefore am unable to describe the hinge-structure or animal. The cara- pace is, however, so remarkable that I cannot place it in any described genus. It is the largest of British CytJieridce. Sarsiella capsula, n. sp. Carapace nearly circular, with a short rostriform process running out from the extremity ; dorsal and ventral margins each nearly semicircular ; anterior margin completely and widely rounded ; posterior with a rostrate process below the middle, the ven- tral margin rather angled in its upward slope, but the dorsal perfectly rounded. Surface of valves extraordinarily rugose, with concentric greatly elevated carinae enclosing a deep hollow in the centre of the valves, and on their exterior side having numerous radiating ribs pass- ing off in all directions to the margin; interstices of these ribs and inner slopes of carinse sculptured with circular pittings. Ventral aspect very irregular, in the centre a quadrangular flat portion sculp- tured with circular pittings. Anterior portion with tuberculately con- vex gradually approximating sides ; posterior portion consisting of the rostriform process, which is seen projecting beyond the truncate extre- mity of the quadrangular portion. End view with flat sides dorsally arched, ventrally truncate. The valves are very much compressed, though appearing more tumid than they really are, on account of the great elevation of the sculptured surface. Length about T^- inch.

A genus Sarsia is already established in honour of the father, Professor Sars. I have given this genus a diminutive termination in reference to the son, one of the ablest and most accurate of the younger naturalists of the day, whose admirable Monograph on the Scandinavian Marine Ostracoda points to a fitness in associating his name with that order. 294 REPORT— 1868. Gytheropteron multiforum (Norman). Common, 30-140 fathoms. cdatum, G. 0. Sars, Overs, af Norges mar. Ostrac. p. 81. "Lateral protuberance very large, triangular, slightly inclined downwards, and running out into a strong mi&ro,' which projects at the sides ; its hinder margin furnished with (about twelve) flattened teeth, the two inner- most much larger than the rest, and in the form of quadrangular serrated laminae. Lateral aspect of female elongated ovate, the greatest height, which is in the middle, much less than half the length, equally rounded in front, behind projecting into a very large process, which is obliquely truncate at the end ; dorsal margin regularly arched, ventral slightly sinuated, the lateral protuberance projecting below in the centre of the ventral margin. Dorsal aspect almost cruciform, the greatest width (between the lateral protuberances) ' exceeding twice the height, and even somewhat surpassing the length, suddenly attenuated in front, and more gradually behind. The shell of the male scarcely differs from that of the female except in the smaller size. Yalves white, pellucid, smooth, finely toothed on the front margin." A single specimen of this interesting addition to our fauna, in sand dredged 5-8 miles east of the Island of Balta, in 40-50 fathoms.

Length >7L- inch. St. Magnus Bay, 30-60 fathoms. I place this species provisionally in the genus Bytlwcy there, as it seems more nearly related to B. sim- plex in general structure than to any other Ostracod. The lateral aspect of the carapace finds its nearest counterpart in Bairdia angusta, G. 0. Sars; but whereas that species is tumid this is exceedingly compressed. Pseudocy there caudata, G. 0.

This is the only Shetland species I have as yet determined, but I have seen others. nigricauda, n. sp. Antennae shorter than first segment of body, 21- jointed; joints very short, all except first and last two shorter than broad. Lower antennae stout and strong, two- thirds as long as upper antennae ; third joint with a seta at distal extremity of hinder margin ; fourth (last) joint terminating in six long seta3. Last feet 1 -branched, well developed, with a strong seta on the middle of the outer margin, and two similar terminal setae, one at each angle of the extremity, with a very delicate and minute seta in the middle between them. Caudal laminae extremely long and slender, more than equal in length to three preceding segments, of a dark brown colour throughout the greater part of their length. A marine species found among Laminariae in Shetland, and also at Tobermory in the Isle of Mull, abundantly. The black colour of the basal portion of the caudal laminae is a very useful characteristic by which to distinguish the species with a low-power lens when mixed in a mass with other Copepoda. In the male the antennae are only 17-jointed, and the caudal laminae shorter, about equal in length to the two preceding segments. pallidus, n. sp. Upper antennae shorter than first segment of body, 11- or 12-jointed (the basal joints not very distinct) ; last two joints longer than broad, last joint but two broader than long, two joints pre- ceding this long, rest shorter. Caudal laminae scarcely twice as long as broad, and shorter than the preceding segment. 296 REPORT— 1868. Another marine species found among weeds at Hillswick, Shetland, and also at Tobermory in the Isle of Mull. A much smaller species than the last, and, if it were not for the greater number of joints in the antenna, not unlike C. magniceps of Lilljeborg. Longipedia coronata, Claus, Die frei lebenden Copepoden, p. Ill, pi. xiv. figs. 14-24. Abundant at Hillswick. Amymone falcata, n. sp. Superior antennae in female 8-jointed ; second joint the longest, fourth shorter than any of preceding ; in male second and fourth joints subequal, and twice as long as third. First segment in- feriorly much produced, and extending backwards in an acute falcate form. Hand long ovate, palm fringed with long cilia ; finger nearly as long as palm, very slender. The coalesced sixth segment has the infero- posteal corner produced backwards into a somewhat hamate spine-formed process. Pereiopods long and slender, extending beyond the body. In most particulars this species comes near to A. sphcerica, Claus ; but the first segment is widely different, being of similar form to that of A. harpacticoides, Claus, but still more produced.

First feet with the branches shorter and stouter than usual, subequal in length ; outer much stouter than inner, its inner margin glabrous, except three or four cilia close to the base, outer margin ciliate ; a large lanceolate, ciliated spine on the peduncle ; a spine at distal extremity of first, and another near the extremity of second joint, which is only about twice and a half as long as broad ; last joint with three terminal spines and a seta, the innermost spine more slender than and about half as long again as the next: inner branch much more slender than outer, 2-jointed ; first joint long, margins glabrous, inner with a seta rather nearer to the base than to the ex- tremity ; second joint terminating in two claw-spines, not very unequal in length. Last feet with the outer branch obovate, margin ciliated, with six setae on the more distal portion of the outer margin and the extremity ; the innermost seta the longest, and the two following close together, and very much smaller than the others : inner branch rather shorter than outer, five setae on distal portion of inner margin and at the extremity, ciliated between the setae, and the seta nearest the base plumose ; the setae not differing greatly in length, but the third rather the longest. Caudal laminae with five setae, which are peculiarly swollen at the base ; the innermost but one the longest, the next half its length, the others very short, spine-like. In the male the abdominal segments have rows of spinules on the sides ; the external branch of the last feet is narrow, with seven setae, of which the innermost but one is much the longest, and the next is minute; the caudal setae are not swollen at the base. First feet as in the female. Found among Lami- nariae in Bressay Sound, 1867 ; and also at Tobermory, in the Isle of Mull, in 1866.

Gregariously abundant ; in immense pro- fusion on the Outer Skerries Haaf, 40 miles east of Whalsey Lighthouse ; comparatively scarce on the Unst Haaf; St. Magnus Bay frequent. The bulk of specimens procured do not exceed three-fifths of an inch in dia- meter; one specimen, however, measures 1^- inch. The spines are generally more or less of a green colour ; but a beautiful variety also occurs in which they are vermilion-red, tipped with white.

In deep water, Shetland Haaf, scarce, and dredged in 40 fa- thoms, near the Feme Islands, on the Northumberland coast. It is also among the Echinodermata dredged by Messrs. Carpenter and Thomson in the ' Lightning ' expedition during the past autumn in lat. 60° 28' N. long. 6° 54' W. in 500 fathoms, stones and mud, and a temperature of 32°. Distinguished at a glance from Drbbachiensis by its more slender spines and their coloration, which in the latter species is green or purple, or a mixture of those two colours and white. When the spines are cleared off, the shell is found to differ in having only one primary tubercle to each interambulacral plate, while in Drbbachiensis there are ON THE SHETLAND CRUSTACEA, TUN1CATA, ETC. 315 three or four tubercles much larger than the rest, the central one being only slightly larger than the lateral.

(1857), p. 33, pi. vii. fig. 2 (but not A. gibbosus of Agassiz) . This species is certainly not A. gibbosus of Agassiz. It is widely different from E. cordatum, but closely allied to A. ovatum, than which it is much larger and different in many particulars. The name I pro- pose for it is in allusion to the beautiful pennatifid pedicellarise with which it is furnished, and which are wholly unlike those of E. ovatum. The specimen procured by Barrett was " dredged in 25 fathoms on the south side of Bressay Island, Shetland, on a coarse sandy bottom." I have myself seen three specimens of the species from as many different localities, one dredged by myself in 1867 in St. Magnus Bay, Shetland, another procured by Mr. D. Robertson in the Clyde district, and the third obtained by Mr. Hodge off the Northumberland coast. — - ovatum (Leske)=A/mphidotus roseus, Forbes, British Starfishes, p. 196.

Very near to S. purpureus, but the shell much higher and more tumid dorsally, and the hinder portion more produced and narrower in comparison with the anterior extremity. The colour is much deeper, being of a very deep purple hue in every part ; the larger spines of the interambulacral areas are not conspicuously larger and longer than the rest ; the ambulacral fascioles are very narrowly lanceolate, four and a half to six times as long as broad, and thus much longer in proportion to their breadth than in S. purpureus, in which they are from twice and a half to thrice and a half or, very rarely, four times as long as broad *.

The discovery of this species in the Shetland sea is of very high interest. It is one of several instances of large conspicuous Mediterra- nean species turning up in 'the great depths of these northern waters, and which as yet are unknown at intermediate localities. S. meridional-is was dredged in 100-140 fathoms, 25-35 miles N.N.W. of Burrafirth Lighthouse, in company with Cidaris papillata, Archaster Parelii, Nor- rnania crassa, Tsodictya laciniosa, liaphioderma coacervata, &c.

" Peter," who was Forbes's dredger, was indeed true to his word when he stated to me no man knew as he did where the " Puddings " were. The contents of the dredge on the very first haul was a sight not soon to be forgotten. It was literally filled with C. frondosa. There rolled out upon the deck thirty or more of these huge, deep purple, smooth, slimy Holothurians, measuring from 10 to 18 inches long, in every state of expansion and contraction, evi- dently greatly discomposed at their novel situation, and in their hurry to withdraw their much-branched tentacles and make things as snug as they could, squirting out streams of water from their capacious maws. • fucicola (Forbes ULINA; D'Orb.

A. M. NORMAN'S Report. Gidaris papiUata, Leske. I find that by some accident I have omitted to notice this species in the enumeration of species. It appears to be absent to the east and north-east of Shetland, as during our dredging in those directions we never saw any trace of it, and the fishermen at the Out Skerries were unacquainted with it. The specimens which have been procured through fishermen have been all from the western coast ; and we had the pleasure of dredging the Piper in some numbers, 25-35 miles N.N.W off Unst in 110-170 fathoms in company with Spatangus meridionalis and other rarities. They appear to be very sluggish in their movements, as though kept alive for some time in a large tub of water, they showed very little inclination to change their position ; of course, however, they found themselves placed in very unusual and probably very uncongenial conditions.

The specimens of " Amphiura elegans " recorded in the foregoing Report from " 40 fathoms, St. Magnus Bay," belong to A. tenuispina, Ljungman. That author at first described this form as a species, but in his more recent memoir considers it to be a deep-water form of A. elegans. On the other hand I at first regarded it in the latter light, but now think it may be a distinct species. For its characters I must refer the reader to Ljungman's paper. I find specimens of this Ophiuridan among the Echinodennata procured in the ' Lightning ' expedition, and sent to me for examination by Messrs. Carpenter and Thomson ; and dredged lat. 59° 40' N., long. 7° 20' W., on a bottom of fine mud in 530 fathoms and a temperature of 47° Fahr. Pocillipora interstincta, Fleming, Brit. Anim. p. 511 ; Johnston's British Zoophytes, p. 194. This coral, found by Dr. Hibbert in the Shetland sea, has been an obscure species of which we have been able to make out nothing hitherto. I have recently, however, seen specimens of a highly interesting coral procured by Messrs. Carpenter and Thomson in the ' Lightning ' expedition oif Cape Wrath, lat. 59° 5' N"., long. 7° 29' W., in 189 fathoms, and also a fragment sent to me to examine by Mr. D. Robertson, who procured it from Faroe, which exactly correspond with Flemings brief description ; and as the specimens which I have seen are from the north and from the south of Shetland, there is every like- lihood of its having been found at the intermediate locality. A de- scription of the species will be given by me in the Report of the Inver- tebrata procured in the * Lightning' expedition.
