Ava meeting held in the rooms of the Natural History Society of Northumberland, Durham, and Newcastle upon Tyne, the 25th April, 1846, (The Reverend the Vicar or Newcastiz in the Chair) On the motion of Ratpn Carr, Esq., seconded by Josep H. Fryer, Esq., It was unanimously resolved, I. That a Society be formed, under the name of the TyNESIDE Naturauists’ Fienp Cuus, for the practical study of Natural History in all its branches, and that the Antiquarians of the dis- trict be invited to unite with the Club for the promotion of their pursuits through its meetings. II. That the Officers of the Club be a President, Vice-Presi- dent, a Committee, and a Secretary, all to be chosen for the year at a general meeting of the Club, to be held in Newcastle on the Thursday of the Epiphany Quarter Sessions. III. That.the members of the Club shall hold five field meet- ings during the year, in the most interesting localities for inves- tigating the Natural History and Antiquities of the district.— That the places of meeting be selected by the committee ; and , that timely notice of each be communicated to members by a cir- cular card from the secretary. IV. That those members to whom it may be convenient shall partake of breakfast together, at the nearest country inn, at ten o'clock, after which the researches of the day shall commence. V. That the hour for a frugal dinner be appointed by the VOL. I. B 2 FORMATION OF CLUB. chairman, during which any papers which he may have received from members of the Club shall be read from the chair. VI. That as members must incur some trifling expense in reaching the place of the field meetings, no subscription to any general fund be required, beyond the amount of five shillings yearly, to be laid out in defraying the cost of printing such papers as may be selected for that purpose, and to meet any ex- penses which may be incurred for stationery, postage, or other unavoidable outlay. That the cost of any lithographic or other illustrations be defrayed by the author of the paper for which they may be required. VII. That the papers of the Club be printed in a cheap octavo form, and distributed gratuitously to the members. VIII. That a class of honorary members be admissible, in which shall be included any ladies distinguished by their attain- ments in the study of Natural History, or local Antiquities, or to whom the Club may be indebted for the communication of papers or specimens. IX. That at the close of each year the president be requested to favour the Club with an address, containing a written sum- mary of its proceedings at the several field meetings, together with such observations from himself as he may deem conducive to the welfare of the Club and the promotion of its objects. X. That all candidates for membership shall be proposed. and seconded by existing members, either verbally or in writing, at any meeting of the Club. XI. That the Club shall endeavour to discourage the practice of removing rare plants from those localities of which they may be characteristic, and of risking the extermination of rare or in- teresting birds by wanton persecution. XII. That on the other hand, members be requested to use their influence with landowners and others for the protection of the characteristic birds of the country, and to dispel the preju- dices that are leading to their destruction. XIII. That consequently the rarer botanical specimens col- lected at field meetings, be chiefly such as can be gathered with- out disturbing the roots of the plants; and, that notes on the habits FORMATION OF CLUB. 3 of birds be accumulated instead of specimens, by which our closet collections would be enriched only at the expense of nature’s great museum out of doors. XIV. That in like manner the Club shall endeavour to culti- vate a fuller knowledge of local antiquities, historical, popular and idiomatic, and to promote a taste for carefully preserving the monuments of the past from wanton injury. The meeting then proceeded to elect the officers for the first year, and the following were appointed PRESIDENT. Rapa Carr, Esq., Dunston Hill. VICE-PRESIDENT. Tue Rev, Joun F. Biacr, Ovingham. SECRETARY. Mr. Joun THORNHILL. COMMITTEE. JosepH H. Fryer, Esq. JosHua ALDER, Esq. W. K. Lorrus, Esq. It was also resolved, that such parties as may signify to the secretary, at the Library of the Literary and Philosophical So- ciety, their wish to become members, shall be admitted without being formally proposed, until the first general meeting of the Club, after which period the tenth rule shall take effect. The thanks of the meeting were then voted to the Vicar, as chairman, and to Mr. Carr, for having suggested, and for his exertions in the formation of the Club. (Signed) R. C. Coxs, M. A., Vicar of Newcastle, Chairman. At a general meeting of the Club, held on Monday the 11th May, 1846, Rapa Carr, Hsq., President, in the Chair. On the motion of the secretary, seconded by J. H. Fryzr, Hsq., It was unanimously resolved, I. That the Tyneside Naturalists’ Field Club undertake the / / 4 FORMATION OF CLUB. formation and publication of correct lists of the various natural productions of the counties of Northumberland and Durham, with such observations as their respective authors may deem necessary. Also that a succinct account of the Geology of the district be prepared. II. That as mistakes may occur in the proposed lists, and as it is of importance that an authentic collection should be acces- sible when any doubt may occur as to a name or species, that local collections be formed and placed, with the consent of the Natural History Society, in the Newcastle Museum. The col- lections to be the property of the Natural History Society. That the specimens be either kept separate or incorporated with the mass of the collections, as may be convenient to the managers of that institution, it being a condition, that the specimens be distinguished by some mark to shew that they refer to the lists. III. That the proposed publications be printed in a cheap form, and sold at a low rate. IV. That sub-committees be appointed from the general com- mittee, and from the other members of the Club, to carry out the foregoing resolutions. V. That the parties forming those sub-committees shall, along with the members of the general committee, form a committee for considering the extent and details of the proposed publication, anid such other matters as may be necessary in connection with ff the scheme. VL. That the following gentlemen be the sub-committees :— MAMMALIA AND ORNITHOLOGY, Messrs. Jonn and Atpany Hancock. AMPHIBIA, ICTHYOLOGY, AND RADIATA, Messrs. R. E. Bewicx, Joun Hancock, and M. J. F. Srpyey. MOLLUSCA, CRUSTACEA, AND ZOOPHYTES, Messrs. J. H. Fryer, Josoua Atper, Aupany and Jonn Hancock. ENTOMOLOGY, Messrs. James Harpy, J. T.

Hurton, F'ryer, Sopwitu, Lorrus, and Kine. VII. That, for fully carrying out the plan, the assistance and co-operation of parties pursuing Natural History in the north of England, whether members of the Club or not, be requested, in furtherance of the undertaking. VIII. That the papers and lists collected and published by the Tyneside Naturalists’ Field Club, be at the disposal of the Na- tural History Society, for printing in the Transactions of that institution, if its committee shall think fit, and that it be re- quested, that the Club may have the use of such of the papers already published in the Transactions of the said Society, as may be of service in preparing the proposed account of the Natural History of the district. IX. That a copy of the foregoing resolutions be submitted to the committee of the Natural History Society, and that their attention be particularly drawn to the 2d and 8th resolutions*. The thanks of the meeting were then given to Mr. Carr, for the able manner in which he had presided over the business of the meeting. * The resolutions were handed accordingly to the committee of the Natural History Society, who resolved, ‘That the committee of the Natural History Society cordially agree and sanction the Rules and Regulations of the Tyne- side Naturalists’ Field Club, as faras the Natural History Society is con- cerned.” 8) THE PRESIDENT’S ADDRESS AT THE FIRST ANNIVERSARY MEETING OF THE SOCIETY. GENTLEMEN,—When our Naturalists’ Field Club was set on foot, in April last, we had felt ourselves stimulated, and were also happily directed, by the example of a body of gentlemen in Berwickshire, and on our side of the Tweed, who had been asso- ciated during several years for the purpose of searching into the natural productions of that district. Not only had their pro- ceedings been successful in adding new plants to the phytology, and new animals to the fauna, of Berwickshire, and even of Great Britain itself, but they had struck out a mode of carrying forward their researches, which made the means as delightful as the end. The object being to cultivate, diffuse, and advance the knowledge of the works of the Creator within the limits of a certain tract of country easily accessible, the means chosen were long and pleasant rambles on foot during fine days in the sum- mer half-year, and in society capable of affording mutual instruc- tion. They did not indeed forget to eat a hearty breakfast, before leaving the village inn where they might happen to meet, nor to dine together at the end of the day ; but being very hun- gry, and having often a good distance to go ere reaching home, they made short work of the repast. There was neither time nor inclination to permit their active and instructive meetings ‘to degenerate into dinner-traps, after the too common custom of this good country of ours. By these means men were brought together from town and country, as many as were really inter- ested in some branch of natural science or in. the study of anti- quities, and no others came. The Society has, consequently, split upon no rock, but has gone on and prospered. Long may it do so, for the materials to be examined and re-examined can never come toanend. One and the same locality needs not to be revisited for long at the same season, unless by design for the sake of comparing different years and different kinds of weather, THE PRESIDENT’S ADDRESS. 7 in their influence on plants and animals. It may be doubted whether any man can live long enough to understand nature too well in the fields, waters, and rocks, within a walk of his own house, much less within the country, or the whole basin of a con- siderable river. But the knowledge gained in our own district, and maturely considered, will arrange itself in the mind as a centre round which may be grouped facts and observations drawn from other regions, whether within our four seas, or far beyond them ; and I think we may feel sure that no men are more likely to make a good use of increased facilities of visiting other situa- tions, on the wings of steam, than those gentlemen who have so steadily bestowed their attention on the Berwickshire hills, dales, and sea-beaten shores. It has been one of the rules of that northern club that, at the end of his year of honour, the President should read, at a general meeting, an address, giving some account of what had been done, and of the observations of natural objects made at the several field meetings; together with any further remarks that he might deem adapted to the occasion. A desire having been conveyed in one of the resolutions passed on the formation of our Tyneside Club, that a like address should be read by its President before vacating his place, I will now do my best to obey the injunction. First, however, let me observe how much I regret the unseemly prolongation of my tenure of the chair, beyond the week of the Epiphany Sessions, when it ought to have terminated. The oc- casion of the delay in this matter, however, will, I am sure, suf- ficé to excuse it on my part, since it was no other than a serious illness of our esteemed and excellent Secretary, Mr. Thornhill, without whose aid and presence it was felt we could not proceed but at great disadvantage. The present meeting may be con- gratulated that our Secretary is now able to be amongst us, and I trust when I have read the minutes kept by him of the pro- ceedings of each field-meeting, it will be admitted by all that, though of some length, they are not spun out by any useless or irrelevant matter, and that there is no part of them that could be properly curtailed by another hand. Indeed, in justice to the researches of those gentlemen who exerted themselves in. the 8 FIRST FIELD MEETING. cause of natural history, and of the Club, at each field-meeting, I, for one, cannot see how a more succinct record than Mr. Thornhill’s could be either satisfactory in the present year, or useful for after-reference and comparison, when to look back to it may be both pleasing and instructive. TI, therefore, beg leave now to read the minutes taken by the Secretary ; and at the end of some of the days, by way of showing that this course is not followed out of sheer idleness, I will subjoin some remarks on what appears to have been always a neglected branch of local an- tiquities—namely, on the older and purer forms, and the original meaning, of some of the names of localities visited in that excur- sion. FIRST FIELD MEETING. 20th May, 1846. A party of sixteen of the members assembled to breakfast at Ovingham, at 10 o'clock. After breakfast they proceeded up Whittle Dene, some having first visited the old church at Ovingham, the tomb of Bewick, &c.; others the garden of the Rev. Mr. Bigge, the Rec- tor, where they were shewn many of the rarer British plants un- der successful cultivation. The party spent a very pleasant day in the Dene and neigh- bouring fields, the only interruption being a rather heavy thun- der-storm, which passed over the Dene in the afternoon. The following is a list of the rarer objects of Natural History, collected or observed :— The nests of the Grasshopper Warbler (Sylvia Locustella), and of the Long-tailed Titmouse (Parus caudatus), were found by Mr. John Hancock, the former being very seldom met with. The Golden Crested Wren (Regulus auricapillus) was also observed. Twenty-three species of Shells were collected. The Dene and neighbourhood are rather rich in the number of the plants growing there; not many of them, however, very rare. FIRST FIELD MEETING. 9 Those most worthy of notice are,—in the Dene, Ranunculus au- ricomus, Trollius Europeus, Euonymus Europeus, large hairy variety of Pragaria vesca, Carduus heterophyllus, Myosotis sylua- tica, Orchis Morio, Listera Nidus-avis, the last-named plant was found by the Rev. Mr. Bigge, and brought by him to his garden at Ovingham. Convallaria majalis, one of the very few really wild northern localities of this plant. Paris quadrifolia, Polypodium Dryopteris. In the neighbourhood, communicated or pointed out by the Rev. J. F, Bigge,—Sisymbrium Sophia, Arenaria verna, by the side of the river a little below Ovingham, Nepeta Cataria, Verbena officinalis, Botrychium Lunaria, and Ophioglossum vulgatum. THE PRESIDENTS NOTES ON THE SECRETARY S REPORT OF THE FIRST FIELD-MEETING. The party proceeded as far as the township and farm-stead of Spital. It has been said that here had been situated an hos- pital, or religious house of some kind, but on what evidence I could not learn. If this origin of the name should not be sub- stantiated, the features of the situation will easily suggest ano- ther, for there is hard by a somewhat remarkable “spout” or waterfall, where the burn tumbles over a ledge into a deep circu- lar basin. I do but mention the circumstance because this fea- ture may soon be lost by the diversion of the burn itself to feed the new reservoirs for supplying Newcastle with water. There is at Spital a clear mineral well, impregnated with iron and sulphur; and around it the moss or bog is abundantly sprink- led with that most elegant floweret, the Primula farinosa. The long woodland dene, in which our day had been so plea- santly spent, takes its name from the township of Whittell, Whit- tall, or Whitt-hall. In the earliest list of the townships of Nor- thumberland it will be seen to have as good a claim to the name of White-hall, as the more splendid structure in Westminster it- self. Hall is the Old English and Anglo-Saxon name for the better sort of houses, such as were inhabited by small landowners, or in other words, by yeomen, (aed-man, a man possessing pro- perty.) No spelling can be worse than that of the modern VOL. I. G 10 SECOND FIELD MEETING. “ Whattles” and “ Thropples,” in which this good old ending has: reached the last shape of corruption, and the whole word has: been utterly debased. The name of Ovingham, itself, belongs to a very interesting class of names, indicating the homes or abodes of particular Anglo-Saxon families ;—in this case, it is the home of the Offings, or sons and daughters of Offa, whosoever that patriarch may have been. The Anglo-Saxon word would be Offinga-ham; literally, “of the Offings the home.” ‘There is an excellent early English spelling of this name, among others of like structure, in the old records called the Pipe-roll and the Ecclesiastical Inquests, which well represents our pronounciation of the soft g in such cases, al- though in most other parts of England that letter would be hard. When written Ovingeham, as we may find it in the old national documents, etymology and actual pronunciation are at once con- ciliated. Before endings in ton like Ovington, though the meaning of the first part of the word is the same, a different analogy prevails and the common spelling is as correct, as in Ovingham for Ovingeham it is inaccurate. Just over the water is Eltringeham, the well- chosen abode of the Eldrings or offspring of some patriarchal settler called Eldric or Eldred, who no doubt had an eye to fish and fowl as well as to the picturesque. I trust that the meeting will forgive this passing digression, which has been made partly in the hope of inducing some anti- quarian brothers to come and wander over the country with us next summer. SECOND FIELD MEETING. 3rd May, 1846. The second field meeting was held at the pleasant village of Shotley Bridge. The party breakfasted at that place, and then proceeded up the Derwent to the Snape, visiting the Sil- ver-tongue lead mine in their way. On an eminence over- SECOND FIELD MEETING. 11 looking the Snape, and commanding an extensive and beau- tiful view both up and down the Derwent, a marquee, amply stored with refreshments, by the kindness and attention of Mr. Hutton and Mr. Nicholas Burnett, had been erected, and the good things it contained were duly appreciated by the party as they came straggling up. Some having been seeking plants, ethers insects or shells, some fossils, whilst others had joined that they might enjoy a pleasant day’s ramble amongst the beautful scenery of the neighbourhood. After their luncheon, the party proceeded to Hownsgill, and thence back again to Shotley Bridge, where they dined. The day was remarkably fine, and every one was evidently pleased and desirous to please, so that the excur- sion passed off as pleasantly as might be. Many interesting plants and other objects of Natural History were observed, amongst others the Maiden Pink, ( Dianthus deltoides,) which was new to the district of the excursion. Some papers were read, and lists of discoveries handed in. A paper was read by the President, Ralph Carr, Esq., from Mr. Hardy, of Gateshead, mentioning se- veral insects which he had found, and which had not before been noticed in the neighbourhood of Newcastle, adding several inter- esting notices of their habits. Mr. Bold also described the habits of a species of Death-watch, new to the Newcastle district; of which he exhibited specimens in the various stages from the caterpillar to the perfect insect. Mr. King, the Curator of the Newcastle Museum, gave an account of the results of a dredging expedition off the coasts of Northumberland and Durham, in which he had the good fortune to capture several shells, and other marine ani- mals, new to those coasts. He also mentioned several other sea shells which he had lately obtained, and which were new to the district. He exhibited, besides the specimens already alluded to, numerous examples of other shells, which although not new, were remarkable for their size and beauty, and for the way in which they illustrated the history of the different species. He also exhibited some small, but very beautiful specimens of coral. —The following is a list of the species new to the coasts of Northumberland and Durham :—Crass—A new species of the Genus Mga. Hcuinoperms—Psolus squamatus. SuE~is— 2 SECOND FIELD MEETING. Panopea Biwonea, Pecten Landsburghii, Fusus Norvegicus, F. Turton, Fusus, a new species allied to F. corneus, Trochus millegranus, Natica Grenlandica, Hypothyris ( Terebratula) psittacea, Axinus (Cryptodon) flexuosus. Corats—Retepora Beaniana. Sponazrs—A new species of Halichondria. Besides the above-named species, Mr. King stated that he had obtained from time to time several dead shells, which he supposed to have been washed up from a tertiary shell bank situated twenty miles from the northern part of the coast of Northumberland, viz. :— Astarte Gatrensis, not found living on the east coast of England, but found fossil at Bridlington, and living on the west coast of Scotland ; Saxicava sulcata, a species nearly allied to S. rugosa, but much larger, only found fossil on this side of the island, but living in Baffin’s Bay. A species of Mya, allied to IV. truncata, received living from Greenland, by Mr. A. Hancock, and named by that gentleman J. Grenlandica ; it is found in a fossil state in Sweden, on the shores of the Gulf of St. Lawrence, and in the Isle of Bute. The secretary mentioned that he had noticed in a ditch at Marsden, Durham, Callitriche platycarpa, which had not been be- fore announced as a plant of this district. He also announced that, in company with Mr. John Storey and Mr. John Thompson, he had noticed new habitats for one or two of the rarer Northumberland plants, viz.: Pyrola minor, Carduus heterophyllus, and Rubus saxatilis, in Cockton wood, near Chesterholme. The insects mentioned by Mr. Hardy in his paper, as worthy of particular notice, are Ophonus pubescens, by the Wear, in Southwick Marsh, a little above Sunderland; Cateretes bipustu- latus, at the same place. He had found the same insect by the Derwent, near Winlaton Mill. On the bog below Hilton Castle he found Lphistemus gyrinoides, Tachyerges Salicett, Crioceris tenella. In old grass fields in the same vicinity he found Gym- naetron tricolor (first found in this vicinity by Mr. T. J. Bold). Of Dipterous insects he noticed Ptychoptera paludosa; Beris clavipes ; Chrysomyia polita and Chrysogaster viduata, and (by far the rarest) Vemotelus nigrinus. On the Derwent, near Gib- SECOND FIELD MEETING. iS side, he had found Brachyopa bicolor, Chrysostoxum bicinctum, and C. arcuatum, Cheiloxa ruficornis, and Atheria Ibis. Mr. Bold described the habits of Anobiwm molle a species of death watch, which he had found in considerable numbers near New- castle. This paper will be found in its place in the Transactions. The rarer insects noticed during the excursion by Mr. Bold, were Gymnaetron niger, Apion subulatum, A. Spencit and A. striatum. In addition to these Mr. B. caught upwards of sixty species of beetles, the names of which will appear in the classi- fied list now preparing by Mr. Bold and Mr. Hardy. In addition to the Maiden Pink mentioned, the only plants worthy of particular notice are Aguilegia vulgaris, near Allans- ford ; Parietaria oficinalis, on the bridge at the same place ; Orobanche major, abundant ; and Fedia dentata, in the corn- fields ; also, Hchium vulgare, in great abundance by the Der- went, above Allansford. The Geological features of the district travelled over are, in the words of Mr. Hutton, “interesting, though simple. It is well known that in the North of England the carboniferous for- mation naturally separates itself into three divisions, the upper one characterised by an abundance of coal, the under one by a large development of limestone—these being usually designated the “coal measures,” and “the mountain limestone formation ;” between these a thick series of beds of coarse grit and slate are interposed, called the “millstone grit.” It was upon this interme- diate group almost entirely that the excursion was made. In de- scending the hill from Medomsley, or Conside, towards the Der- went, the outcrop of all the lower members of the coal formation is passed over, the lowest workable bed of coal, the ‘ Brockwell Seam,’ cropping out in the hill side, very little above the hotel at Shotley Bridge. Following the Derwent, as the party did, up- wards from Shotley Bridge, the whole thickness of the ‘ millstone grit’ (brought up by the rise of the strata) was passed over by the time the party had arrived at the Silver-tongue lead mine, where, in the bed of the Derwent, the first stratum of mountain limestone, called the “ Fell Top Limestone,” makes its appear- ance. The millstone grit possesses few characters of interest 14 SECOND FIELD MEETING. sufficient to comment upon, except as having afforded rough millstones, perhaps, for ages, the name of the formation being derived from its use in the very district traversed by the Club. Metalliferous veins are almost exclusively confined to the lower divisions of the mountain limestone ; but sometimes veins of lead do occur in the middle series, and at Healyfield have been worked for many years in the millstone grit.” THE PRESIDENTS NOTES ON THE SECOND FIELD-MEETING. Our second excursion was a long and delightful one; the day, however, was intensely hot, whilst all nature was in full life and expansion under the burning sunshine. Fortunately there was a brisk air, and great part of the way was traversed under the canopy of the woods. The resting-place where we enjoyed the hospitable shelter of the tent, and partook of its refreshments, over- looks the course of the Derwent both downward, along in the di- rection we had come, and upward where its character is different, as it flows through an open moorland country. The point where we stood gave us the best possible idea of the geography of the river and great part of its basin. Just below us was a bold and richly-wooded elbow of the banks, forming a promontory on the northern side, and this point is called the Snape. We were told that this curious appellation was in allusion to the beak of a snipe. I fancied it might be a corruption of Snae-hope: but there was no “hope” or short valley there to countenance the supposition. We must compare this name with a place called The Snipe, on the angle of land at the junction of Tarset Burn and Hun- ter’s Burn, in the vale of North Tyne; and also with The Snipe, at the north-eastern point of Holy Island. The Anglo-Saxon original, if such ever existed, has been lost ; but in the Old Norse, the language of the Danes, who so long held sway in these parts, we find the word Snoppa, rostrum a beak. Hence it is not unlikely that both Snape, as applied to a jutting promontory, or point of land, and the name of the bird may have a common origin, and that both are from the old Norse, Snoppa, a beak, or from a collateral Anglo-Saxon expression, which has disappeared. THIRD FIELD MEETING. 15 On the southern side of Derwent are two “ hopes,” or short vales, Herdsel-hope and Hys-hope. Their names are now elegantly di- versified into Horsop and Hysop. Why not at once, Her shop and His shop? As herdsel isin Old English a sheep-fold, the real name of the former little vale is of a pleasing pastoral cha- racter ; that of the latter is not so easy to explain. THIRD FIELD MEETING, Tth August, 1846. The Club was to have assembled to breakfast at Bardon Mill, and to dinner at Haltwhistle, but, owing to the extreme wetness of the weather, the meeting was thin, and some of those who met at breakfast turned back before reaching Haltwhistle. On account of the state of the weather, but little could be seen of a district highly interesting for its peculiar geological features, for its antiquities, and for the numerous interesting plants which its lochs, its rocky hill-sides, and its marshes produce. Its zoology does not appear to have been much investigated, but there seems little doubt that, especially in conchology and en- tomology, a careful examination would repay the naturalist. The only rare plant gathered was Ranunculus Lingua, which the Rev. Mr. Cundill found in a small lake near Walltown. The papers laid before the meeting were— “Notices of some new species of Mollusca, &c., found at Ar- drossan and in the Isle of Arran, in May and June last,” by Mr. Joshua Alder. “A list of new habitats of various of the rarer plants of North- umberland and Durham,” by Mr. John Storey. These new habitats will duly appear in the catalogue of plants now in course of preparation. The President exhibited viviparous heads of the Crested Dogs- tail Grass (Cynosurus cristatus ). A communication, through Mr. Hardy, was read from Dr. 16 FOURTH FIELD MEETING. Johnston, of Berwick upon Tweed, proposing that a joint meet- ing of the Berwickshire and Tyneside Naturalists’ Field Clubs should take place at Alnwick, as soon as the Newcastle and Ber- wick Railway shall be opened, “for mutual encouragement and the promotion of friendly feelings.” THE PRESIDENTS NOTE ON THE THIRD FIELD MEETING. On this, the only occasion when the Club has been interrupted by bad weather, I happened to be absent on a visit to the banks of the Breamish. The day was there overcast and rather sultry, but no rain fell. Distant rolling peals of thunder were heard all day, beginning on the south-west and ending as if the storm had come round into Roxburgshire, behind Cheviot, on our north- western side. FOURTH FIELD MEETING, Friday, \1th Sept., 1846. The Club assembled in the first instance at the house of Mr. Abbs, of Cleadon, where they were shown through the interesting grounds belonging to that gentleman’s residence, by the Rev. G. C. Abbs. They then proceeded to Whitburn, to: breakfast. After which the party separated, some proceeding to seek for shells, &c.—others for insects or plants, as might be their parti- cular pursuit. The principal circumstances which occurred, and which might be considered of more than common interest, were, 1st, that the party which kept on the banks saw a locust fly past them, which, however, they did not succeed in taking. This in- sect appears in this country at considerable intervals ; it is about twenty years since any were seen in this district ; at least if they have been seen, there is no record to that effect. This year, however, they have been seen and captured in considerable num- bers, especially in the district in which the one alluded to above was observed. The second circumstance worthy of particular notice was, that some of the party who had gone to seek for sea- FOURTH FIELD MEETING. 17 shells, &c., caught a crab in the very act of putting off his coat. It is well known that all animals of the class to which the crab belongs, cast their shells once a-year, but there are few instances recorded of the operation having been actually seen taking place. The parties who saw the process, describe it as being very like what a person does when he is wriggling himself out of a coat that is a little too tight for him. Most of the party proceeded northward to Marsden, examining as they progressed, the pecu- liar geological features of the magnesian limestone, here worn into picturesque arches, lofty pillars, or by the never-ceasing action of the ocean, worn into deep and extensive caverns, there cut into towering cliffs, or sometimes crumbling away before the power of the waves, forming heaps of larger or smaller blocks at the base of the main mass of which they once formed a por- tion. After the party had explored this interesting locality as long as their time allowed, they turned their course southward and dined at the Roker Baths Hotel. After dinner, the follow- ing papers were read :— “On some of the habits of the horse leech, Hamopsis sangui- suga, with notices of some rare insects,” by Mr. Hardy. “ Notice of the occurrence of Limnoria terebrans, at the mouth of the Tyne,” by Mr. Albany Hancock. Mr. Hardy also exhibited some very remarkable viviparous heads of the common cocksfoot grass, Dactylis glomerata. . THE PRESIDENT’S NOTES ON THE FOURTH FIELD MEETING. The flight of the locust, which we saw and marked down, and again sprung as if it had been a lark, was strong, quick, and well sustained. The insect evidently had the power of proceeding a long way without any fresh impulse from the ground, and could turn in any direction. It was scarcely smaller as seen flying than the larger dragon flies. The day was cloudless, and the air delightful; an extraor- dinary host of that brilliant insect the scarlet admiral butterfly, Vanessa atalanta, were on the wing. ‘They were flying past us or resting on the autumnal flowers, which are peculiarly fragrant VOL.

Having enjoyed a long ramble as far as Marsden, we returned to the refreshment of an excellent dinner at Roca, for so the older maps denominate the place. The name might seem a lit- tle exotic and romantic, although well bestowed in allusion to the rocks and cliffs along the shore. In accordance with the taste of the present day, the name has been revised, and as there is a railway not far off, it is written Roker, so that it may rhyme with poker and stoker. We had the gratification of being accompanied this day by a learned native of Iceland, Mr. T. G. Repp, late of the Advocates’ Library, in Edinburgh, and now of Copenhagen. Mr. Repp has been the editor and latin translator of the Lardela Saga, and the author of a valuable treatise on Trial by Jury among the Scandinavian nations, and other learned works. FIFTH FIELD MEETING. October 29, 1846, The last Field Meeting of the year was held at Tynemouth, on Thursday the 29th October. The party breakfasted and dined at the Star and Garter Hotel, in that village. After break- fast, the party proceeded to Whitley, visited the quarries, in a pond in which, Mr. A. Hancock, Mr. Loftus, and others, collected specimens of a rare shell, first discovered there by Mr. Alder and the Rev. Mr. Mark, and named by the former gentleman Pla- norbis levis. They then went to Whitley House, where the party had an opportunity of inspecting the very extensive and valuable collection of shells belonging to Mr. J. H. Fryer, who, thinking that the body as well as the mind should be cared for, had provided a very substantial luncheon. After this had been done full justice to, the party proceeded northward, but not far, as the day was waning, and some of the gentlemen wished to ex- amine the indications of the 90 fathoms dike at Cullercoats, and FIFTH FIELD MEETING. 19 also the fine specimen of what is called the “Northern Drift,” at the the mouth of the Tyne. At this latter locality, Mr. Carr, the pre- sident, pointed out several remarkable examples of blocks of va- rious kinds of stone (Basalt, Mountain Limestone, Millstone Grit, Coal Sandstone, &c.)—which exhibited strong marks of glacial action. In the morning three communications were read from Mr. Loftus, viz. :—an account of the occurrence of the glow- worm, near Gibside ; a list of new localities of several rare Bri- tish shells ; and a letter to the President, recommending that the members of the club should communicate at the meetings any information with respect to Natural History, which they may have obtained in their researches, in the intervals between those said meetings. Mr. Albany Hancock read a very interesting pa- per on the varieties of Buccinuwm undatum. This shell, one of the larger Whelks which inhabit our coast, is found at various depths and under various circumstances. Some occurring in 40 fathoms water, some in water of only half that depth, whilst other examples are found within the tide-marks. Mr. Hancock stated, that as the circumstances in which the shell is found, vary, so the character of the shell is altered. The comparatively deep water variety is thin and delicate, occasionally exceedingly so, because it lives at the bottom of water, which, at the depth mentioned, is nearly, if not entirely, still. The bottom of the water, on which it lives, is also muddy. Coming nearer in shore, or into shallower water, we find another form of this shell, thicker and stronger than the last. We have not time to describe all the varieties, we may, however, state that the extreme forms are so opposite that they have been described as distinct species. But a careful examination of the habits and habitats, shews that the variety of form, under which they appear, is only what might be expected from the variety of circumstances in which they exist. Mr. Hancock has in preparation a full account of the dif- ferent varieties of this interesting Mollusk, so that the members of this Club, as well as other parties interested in the subject, will shortly have before them an accurate and skilful account of this Protean shell. 20 FIFTH FIELD MEETING. THE PRESIDENTS NOTES ON THE FIFTH FIELD MEETING. On this, our last meeting, for an excursion in furtherance of the objects of the Club, we spent an agreeable and instructive day, notwithstanding the lateness of the season. The attractions in the cabinet and library at Whitley House, were really endless, and I left them with the feeling, that in spite of Mr. Fryer’s exertions that our curiosity should be fully gratified, we had only made a beginning before the shortness of an autumn day warned us to proceed. I had the pleasure of showing, after breakfast, a very good sample of Spanish chesnuts, ripened on the trees at Dunston Hill. They have this year been perfectly matured, per- haps, even more completely than in 1826. We have some fine young trees growing, which were raised from the seed of that season. But the river Tyne is, perhaps, not far from the north- ern limit where this southern tree will bring its fruit to maturity, even in the warmest summers. I will conclude by mentioning a circumstance of the habits of the Tawny Owl, Strix Stridula, which I mentioned to some of our ornithologists at the Ovingham meeting. That bird does not seem to be known as a bold and rapacious robber of the nests of some of our stronger birds at the time when it is feeding its own young. It has been protected now for a few years at Dunston Hill. In 1844 a pair of Tawny Owls reared and ushered into the world three hopeful young, after having fed them assiduously upon the trees for many weeks after they had left the nest. The food must often have consisted in great part of worms, snails, and slugs, for the old birds brought it every minute from the ground in the immediate vicinity of the trees where the young were perched. This, however, might only be considered as a whet to their appetites before dinner ; for the parents made repeated and persevering attacks upon three or four magpie nests, sometimes during half an hour at a time. As the defence was spirited and gallant, they were often repulsed ; but, finally, I found the remains of young magpies under the favourite perch of the young owls, and one morning the bloody head and fea- thers of an old magpie, conspicuous from its size and the want of FIFTH FIELD MEETING. 21 any cerous skin about the beak. This then, ] thought, must have been taken when roosting. In 1845 the old owls alone were seen, and they passed the summer in sedate retirement, and seemed to rest from the labours of propagation; neither did they molestthemagpies. But in 1846they began to be veryactiveearly in the spring, and by the beginning of May again had their young owlets out upon the branches. Walking out about nine o’clock one evening, I heard a pertinacious attack going on against a pair of magpies that had their nest in the top of a very tall sycamore. At last instead of the frantic chattering of the poor magpies, one of them began to shriek in agony like a hare when caught in a noose ; and it was evident the owl was endeavouring to drag it out—the mother bird—by the head from the entrance of the nest. I ran down to the spot to prevent the perpretration of such murder, and arrived in time to separate the combatants by striking against the stem of thetree witha stick. Before the next morning the young of our only pair of rooks had disappeared from the nest, in a situation where nothing but the owls could have injured them. This was too bad ; a decree went forth against the young owls, and they paid the penalty of their voracious appetites. It is thus evident that the magpie’s instinct in arching over her nest is necessary to enable her and her mate to defend it against rapacious birds. Probably the raven, the buzzard, and the kite, may be all disposed to make unfriendly visits, wherever their race has not been exterminated by pitiless gamekeepers. But it is evident that the tawny owl is a formidable enemy. The re- luctance of the rook to build out of society may also be better understood, as it cannot defend its open nest against the owl at night; and also one reason why the instinct of the daw leads it always to seek the shelter of a hole, although, as Mr. Waterton remarks it appears to be as hardy a bird as the rook. That wisdom and beneficence which never err may have given them instincts for other and more important ends than human eyes may ever be able to descry, but it is always gratifying when we think we can in part understand the utility and design of differ- ences so striking. 22 LAST FIELD MEETING OF THE SEASON. I will now conclude by the agreeable statement that our num- bers now amount to more than eighty, and that we have been permitted to add the names of some fair honorary members, who have not only lent us their general encouragement, but have sent some beautiful specimens of dried plants, alge, and corallines, for examination. The last meeting of the year was held on Monday evening, the 15th Nov., 1846, conjointly with the Natural History Society, in the rooms of that institution, the President of the club, Ralph Carr, Esq., in the chair. The President read a paper introductory to a future contribu- tion, concerning various proper names of places in Durham and Northumberland. It was stated that the geography of these dis- tricts is rich in significant terminations, of easy etymology, de- scriptive of hills, vales, waters, woodlands, precipices, pastures, villages, hamlets, enclosures, &c. ;—that although much has been done by the researches of Mr. Brockett and others, yet the ety- mological part of the question may be further elucidated from the Anglo-Saxon and old Norse languages, care being had in no case to trench upon ground under which an older Celtic element might be concealed ; that the different English counties offer great variety in the distribution and grouping of the signifi- cant popular endings, and that to compare them with those near home, may afford no small interest to a traveller ;—that in every part of the country the old popular names possess a certain grace and dignity from their close connexion with the cultivated speech and literature of our Anglo-Saxon fore- fathers ; whilst those of modern invention, with all their affecta- tion of classical or foreign sound, are comparatively worthless. A paper was also read by Mr. T. J. Bold, on the corn-weevil, a beetle which, along with another small coleopterous insect, com- mits fearful ravages amongst bonded corn. Mr. Albany Han- cock’s paper on Limnoria terebrans, a small species of crab which commits great havoc in sub-marine wood-work, was.re-read, as the subject is of great importance from the great destruction of sound ABSTRACT, AND ANNUAL MEETING. 23 timber caused by this small animal, which is not more than the tenth part of an inch in length, and yet from its amazing num- bers in certain localities is truly formidable to those who have to construct and pay for sub-marine wood work. Mr. Peacock, of Sunderland, one of the members of the Club, exhibited specimens of this minute but destructive animal, which, by his account, had committed extensive ravages in the docks of the above-named town. ABSTRACT OF THE PROCHEDINGS OF THE COMMITTEE DURING THE YEAR. In order that the proposed lists might be made as nearly com- plete as possible, it was determined that parties not members should be desired to co-operate. In accordance with this reso- lution, Mr. R. EH. Bewick was requested by the committee to be- come a member, and to be one of the sub-committee for forming a list &c., of the Fishes of the district. Mr. Bewick declined becoming a member, but promised to cordially assist the views of the Club in any way he could. Mr. Embleton, of Embleton, was also applied to for his assistance, but from that gentleman no answer was received. The committee determined also, that the Lists, Transactions, &c., should be printed in 8vo., and that the printing should be entrusted to the Messrs. Hodgson. The last matters of any im- portance transacted previously to the annual meeting were, the fixing of a day for that meeting, and resolving that Mr. Von Voorst should be requested to undertake the publication of the transactions, W&c., of the Club.

The president read a short address detailing the circumstances 24 ANNUAL MEETING. which led to the formation of the Club, and then requested the Secretary to read his report of the various field meetings, to which the chairman appended various remarks as the report of each meeting was read. A letter was read from Mr. Alder, stating that he had received a communication from Dr. Johnston, of Berwick upon Tweed, proposing that the Tyneside and Berwickshire Naturalists’ Field Clubs should hold, in the summer, a joint meeting at Alnwick. This proposition was agreed to, with the understanding that it should not take place until the opening of the Newcastle upon Tyne and Berwick Railway. It was resolved, that in future there shall be one President, three Vice-Presidents, two Secretaries (one of whom to act as Treasurer), and ten Committee. The following gentlemen were elected officers for the ensuing year :— PRESIDENT. Tue Rev. Joun F. Biaee. VICE-PRESIDENTS. J. H. Fryer, Esq. Josnua ALDER, Esq. D. B. Wurtr, Esq., M. D. SECRETARIES.

By T. J. Bou, Esq. [Read July 3, 1846.] Srvc the last meeting of this Society, I have captured in abun- dance Anobiwm molle, Linn., an insect, which, although recorded by Mr. Selby in his “ Fauna of Twizell,” published in the third volume of the “ Annals of Natural History,” has not since then, to my knowledge, been noticed as occurring in the counties of Northumberland or Durham. I found it in the vicinity of Newcastle in its various stages of larva, pupa, and imago. The larva appears to differ in habit from that of the typical species, which is generally found in the interior of wood, whilst this finds its pabulum in the inner bark of the Scotch fir (Pinus sylvestris), forming its tortuous burrows, at one time, wholly in the bark, at another eating equally of the bark and wood, and in very few instances perforating the wood itself. The pupa is enclosed in a fine, soft, whitish, silken cocoon, and is found in the same locale as the larva. The imago, or perfect insect, I found on the same pales in which I got the larva and pupa: they are those pales by the road-side at the foot of Benton Bank. I first observed it on the 31st of May last, and have since, at intervals, noticed it up to the present time. It has a most grotesque appearance when at rest, the head forming a right angle with the body ; and I ob- served, that although it falls when touched, or apprehensive of danger, yet it does not simulate death, as others of this genus do, but runs with celerity or takes wing with a readiness that quite astonished me. Another trait in its character also differs from any thing that I have before noticed in this tribe; I allude to their dismember- ing each other when in confinement. I puta great number of 30 CAPTURE OF ANOBIUM MOLLE. specimens into quills, and when I came to set them the following morning, I found that in the short space of one hour they had so effectually dismembered each other, as not to leave me one per- fect example. Mr. Stephens, in his description of this species, says, that the elytra have “the apex rounded and somewhat glossy;” but does not mention a pale spot, which is just within the apex of each elytron, and which is more particularly conspicuous when the insect is alive. THOMAS JOHN BOLD. Newcastle, July 1, 1846. The specimens exhibited are— Anobiwm molle, in its various stages. Trypodendron domesticum, a rare species, taken by Mr. James Hardy, near Axwell Park, in March last. Ophonus pubescens, also taken by Mr. Hardy, on the banks of the Wear, near Southwick, in May. ( 31) Il.—Wotice of the Occurrence of Limnoria terebrans at the mouth of the Tyne. By Aupany Hancock, Esq. [Read September 11, 1846.] Four or five weeks ago, whilst rambling along the coast at the mouth of the river, I stumbled on the remains of a few sal- mon-net stakes, not far from Clifford’s fort. On examining these stakes, which were near low water mark, I found that they were reduced to less than half their original diameter, by the ravages of a small crustaceous animal, which had pene- trated the wood in every direction, and that I had really got hold of the formidable Limnoria terebrans—the dread of the maritime engineer. The attention of naturalists was first drawn to this destructive little animal by Mr. Robert Stevenson, of Edinburgh, Civil En- gineer, who discovered it whilst erecting the Bell-Rock lighthouse. It had attacked the beams supporting the temporary wooden bea- con, and had done much injury. Specimens of the wood, con- taining the animal, were forwarded to Dr. Leach, who named it as above. Since then it has been found in various ports in England, Scotland, and Ireland: it has also been observed on the coasts of France and the Netherlands, and more recently has been detected in America. The ravages of the Zimnoria are of the most alarming nature : it attacks equally all kinds of wood, except teak ; and in the course of three years it has been known to reduce logs of Nor- wegian pine ten inches square to seven inches, that 1s, at the rate ofan inch in the year. No effectual preventive, I believe, has yet been discovered. Sheathing with copper and driving broad- headed nails all over the surface of the wood are the most suc- cessful modes adopted by engineers: painting and tarring have also been resorted to with variable results ; but any covering of this kind is so liable to be abraded that it cannot be relied on, even supposing that it affords complete protection when first applied. 32 OCCURRENCE OF LIMNORIA TEREBRANS. This animal, so detrimental to our docks and other submerged wooden works connected with marine affairs, is scarcely two lines long, and is otherwise so insignificant in appearance that most persons, at first sight, would deem it unworthy of a thought. It is allied to the sea wood lice (the Oniscide), and is supposed to feed on the wood into which it bores. I have some reason, however, to doubt the truth of this, for I have found minutely comminuted wood in the entrance of the burrows, as if thrown out by the animal. If so, then the Limnoria is no exception» as has been supposed, to the general rule, that all the Crustacea feed on animal substances. In conclusion, I beg to apologise for having trespassed on the time of the Club, with the present communication, which cer- tainly I would not have done, had not the subject of it possessed more than ordinary interest. It belongs also to the district in which we are now assembled, and I thought it proper to make known that we have this troublesome animal at the mouth of the Tyne: and I am acquainted with no better way of doing so than through the medium of this Society. | Newcastle, Sept. 10, 1846. (33) I1l.—Wotes on damage done to Wheat by Cucujus monilicornis and Calandra granaria. By T. J. Bou. [Read Nov. 23, 1846.] I save frequently had my attention drawn to the damage done to warehoused grain, by the corn weevil (Calandra granaria, Linn.) ; and recently, an instance has come within my notice, in which it has been accompanied by another small coleopterous insect (Oucujus monilicornis, Marsh.), and this circumstance hav- ing enabled me to form something like an estimate of the loss which they occasion, I am induced to bring before the Club a few notes on the subject ; hoping that they may not be without interest, especially as no English author has given any direct computation of the havoc committed by those pests. A parcel of two hundred quarters of Rostock wheat, of fine quality, weighing 6libs. per Winchester bushel, was bonded in the summer of 1844 ; and from causes which it is here unneces- sary to mention, was allowed to remain in the warehouse until the latter part of this summer (1846). When sampled it was found to be of various weights ; 60 qrs. weighed 441Ibs. per bushel; 80 qrs. weighed 463Ibs., and the remaining 60 qrs. 56iibs., being an average of 49Ibs. ; and shewing a deficiency of 12%bs. on each bushel, or 96ibs. per qr. ; and on the whole 200 qrs. a deficiency of 19,200ibs.; equal in measure to 38 qrs. 6 bushels ; which at the present (Nov. 4) market value of 64s. per qr., will amount to 124/., nearly one-fifth of the total value of the wheat. But it must be remembered that this calculation is made on the mere loss of weight ; without noticing the great deterior- ation of quality ; for it will be seen, by the sample exhibited, that the insects have taken the farinaceous, or internal portion of the grain, leaving the outer portion, consisting merely of the husk or bran ; and what is left is rendered so “ unsweet ” as to be totally unfit for human food ; consequently, its value is so VOL. I. F 34 ON THE DAMAGE DONE TO WHEAT BY much reduced, that, I have not the least doubt, but that the ac- tual loss is more than double the computed amount. A curious cir- cumstance, and which I do not remember to have seen satisfac- torily accounted for, is the bad condition of all grain infested with weevils, it being always more or less “heated.” This heat- ing the warehouse-men attribute to the natural warmth of the beetles; but I would think, that it is more likely to be caused by the tendency to fermentation of the moistened and injured grain. The difference of weight mentioned—444, 463, and 564 Tbs. per bushel, is caused by the position of the wheat in the warehouse; the lightest is from the centre of the loft, where the grain generally lies thickest, and the heaviest, from the out- side or ends of the heap, which are cooler and not so much in- fested as the centre, where the temperature is much higher, and more congenial to the habits of the insects. The agents in this destruction are Cucujus monilicornis,* and Calandra granaria. The first is a very small beetle not exceed- ing one line in length. Curtis, in the “Journal of the Royal Agricultural Society of England,” Part I, 1846, p. 104, has made some remarks on the species of Cucujus that have been found in granaries, and, amongst others, mentions that, C. mon- tlicornis “ was observed in granaries, and corn-bins, in Norfolk, about 30 years back, in the month of December.” Whether or not this species is attendant on the weevils, [am unable to say. I have cut open some of the grains of wheat, and found as many as five or six individuals in each grain. Curtis, in the wheat that he examined from Ancona, which was infested by C. testa- ceus, found two or three dead individuals, in the interior of the grain, and the husk was pierced with very minute holes. I have also detected C. monilicornis in Madras rice, imported direct from the East Indies. But the principal agent in this mischief is the weevil, and it is not a little singular that the larva, which is said to “make the greatest havoc amongst the corn,” is undescribed by British * JT had a two ounce phial filled with living specimens brought me in the beginning of November. They had a peculiar, strong, unpleasant smell. CUCUJUS MONILICORNIS AND CALANDRA GRANARIA. 35 Entomologists. It has, however, been described, and its trans- formations traced, by Olivier*, whose account has been adopted by succeeding naturalists. The countless multitudes in which the corn weevil sometimes occurs almost exceed belief; the men who had the care of this parcel of wheat assured me, that during the summer they regularly screened it once a month, or once in five weeks, and that at each screening they got about fourteen bushels of weevils.t Thequantity of weevils may appear incredible to those unacquainted with such matters, but it must be borne in mind, that, under favourable circumstances, they increase amazingly. Kirby and Spence, in the “Introduction to Entomology,” Vol. L., p. 170, speaking of the corn weevil say, “sometimes this pest becomes so infinitely numerous, that a sensible man engaged in the brewing trade once told me, speaking perhaps rather hyperbolically, that they col- lected and destroyed them by bushels; and no wonder, for a single pair of these destroyers may produce in one year above six thousand descendants.” De Geer makes them still more pro- lific. He asserts that, “a single pair, in the course of a season, will produce (among themselves, and their descendants,) twenty- three thousand six hundred individuals;{ and an instance came under my own observation, in which six bushels of weevils alone were taken at one screening, out of eight or ten lasts of Danish rye. The weevils do not confine their ravages to wheat and rye, but have been found to attack barley, malt, oats, and maize, with equal readiness; and Curtis observed some, that during the win- ter ate up some pearl barley. The great importance of this subject has led to the suggestion of a variety of expedients for the destruction of the weevils; but unfortunately a practically useful one is still a desideratum. It is said that the odour of spirits of turpentine, and even fumiga- tion with sulphur, have been tried without benefit.

The underside of the thorax is obsoletely and sparingly punctured, and the thighs are black, as are the an- tenn, excepting the basal joint, which is rufous. The 4. 44 CATALOGUE OF THE INSECTS OF strenuus, of Duft., Gyll., Steph., Sturm., Boisd. et Lacord.,—and the A. pygmcus of Sturm and Heer, appears to be identical with A. erythropus of Marsham, which has the underside of the thorax “deeply and thickly punctured.” Mr. Selby considers the puncturing of the thorax a variable character, and is inclined to think that the two species unite. “TI find,” he observes, “the punctures on the underside of the thorax to vary in different examples from faint and indistinct to strong and well marked.” —J.

It comes abroad in the evening, and its retreats may be readily discovered by following the tracks which it leaves behind, in these noctur- nal excursions. Mr. Albany Hancock observes that its chief food seems to consist of Philopedon geminatus ; Mr. Peacock has seen it conquer and devour Ocypus olens ; and we, besides a va- riety of other fare, have detected it preying on Oniscus asellus. 23.

In the Ouseburn, August.— IU, di dix An interesting account of the larva of this species has been given by Mr. Wailes in the Entomological Magazine, vol. 1., 256. The insects, where he observed them, frequented half-exposed blocks of coarse sandstone in brooks, lurking in the slight in- equalities, on a level with the surface of the water, or a little above it. They occur most abundantly in autumn, when the 70 CATALOGUE OF THE INSECTS OF different stages of larve, pups, and perfect insect may be found in company. The larve are “anopluriform, measuring, when full grown, about two and a half lines in length, and half a line in width. They are ofa uniform black, and have the apex of each abdominal segment fringed with very short hairs. Their food is most probably mucor, for they seem to be confined to rough slimy stones.” When full grown, they form oval cells of mud, about two lines in the longest diameter, in which they become pupz of a bright orange colour. 68.

The writer is unknown (Isaac Thompson ?), but it may be gathered, that he entomologized about Newcastle from 1749 to 1760. He mentions R. Harrison, the distinguished mathematician, as hav- ing brought him the eruca of the Puss Moth (Cerura Vinula), “in saliceto suo in Pandon Dean deprehensam, 19 Jul. 1760.” In respect to WV. vespillo, he has written on the margin :—“Stri- dorum vexatus emittit, non multum a murino abludentem.” This mouse-like querulous noise, is also the token of irritation in others of the species.—J.

Mr. Hardy visited the place in the beginning of » June, and found the number of species of insects very limited, and, excepting in one instance, the number of individuals. Insects belonging to the order Diptera were the most numerous. Mr. Hardy met with Ophonus pubescens, which, as he had not taken it before, was interesting. It was extremely local, being confined to the circuit of a few yards, on a rather drier spot than the rest of the locality. On this place he found it by turning over some broken bricks, and by digging in the soil underneath, he found it in considerable numbers; it occurred also among the matted tufts of the Thrift. Those which he found amongst the soil were pale yellow, having but lately emerged from the pupa, which he found also in some numbers. Mr. H. mentioned that although confined to very narrow bounds in the places where it occurs, neverthe- less it 1s a widely dispersed insect, occurring in most parts of the island. Mr. Hardy mentioned in the same paper some of the habits of Brachyopa tricolor, a rare British fly, which he had met with near 96 ABSTRACT OF COMMUNICATIONS. Gibside, in the County of Durham. It is a bolder insect than many of its congeners, suffering a near approach before it rises, and soon returns to the place from whence it had been disturbed. This species also, instead of retiring along with the sun, remains abroad till sometime after sunset. This habit Mr. Hardy also also observed in Pachyta octo-maculata. Mr. H. verified the observations of St. Fargeau on some of the habits of the Zen- thredinide, having caught several species preying on other in- sects. After several observations on the abundance or scarcity of insects generally, this season, he concluded by noticing the capture of two specimens of Bombus Skrimshirianus, which is accounted one of our rarer large bees, but Mr. H. mentioned that he had frepuently met both with it and its nest in Berwickshire. At the September meeting, Mr. Hardy read some notes on the habits of the Horse Leech (Hamopsis sanguisuga ), in which he stated, that he had verified by observation, what had been formerly stated respecting this animal, that the common earth- worm appeared to be its ordinary food. Mr. H. also mentioned some species of plants in which he had observed monstrosities more than usually remarkable. Of Dactylis glomerata, he ex- hibited and described very extraordinary viviparous heads. (97) V.—A Catalogue of the Mollusca of Northumberland and Durham. By Josuvua ALDER. [The preparation of this Catalogue was entrusted to a Sub-committee of the Club, consisting of JosepH Harrison Fryer, Anpany Hancock, and Josuua ALpER, and has been drawn up by the latter with the assistance of the two former. The names of the Sub-committee are indicated in the Catalogue by their initials. | SzvERAL partial notices of the Mollusca, or, to speak more cor- rectly, of the Shells of Northumberland and Durham, have from time to time appeared. The earliest is that of Wallis in the “Natural History and Antiquities of Northumberland,” published in 1769. This work contains an account of 45 species and va- rieties, rather vaguely designated, after the fashion of the older naturalists, but most of which can be easily recognised. They consist principally of the most common and conspicuous species. No further contributions to the conchology of these counties appeared till 1816, when Sir Cuthbert Sharp published in his “History of Hartlepool,” a pretty extensive list of the shells of that locality. This list appears to have been very carefully drawn up according to the best information of the time, but a few species have inadvertently been admitted into it, such as Venus chione, Cardiwm aculeatum, Buccinum lineatum, and Strombus costatus, which are certainly not inhabitants of our coast, and must either have come there by chance, or, what is more probable, other species somewhat similar in appearance have been taken for them. Several species in addition to Sir Cuthbert Sharp’s list were given by Mr. Hogg, in his “Natural History of the Vicinity of Stockton.” In 1822, Mr. Winch published a Catalogue of the Shells found at Lindisfarne, in the “Annals of Philosophy”; stated to be principally furnished by a lady. It was afterwards re- VOL. I. 0 98 CATALOGUE OF THE MOLLUSCA printed in Raine’s “History of North Durham.” Here also one or two species appear to have been included by mistake, but, upon the whole, it is a pretty correct enumeration of the princi- pal shells found on that part of the coast. A “Catalogue of the Land and Fresh-water Mollusca of the vicinity of Newcastle,” by the writer of this notice, was published in our “ Natural History Society’s Transactions” in 1830, to which a Supplement was added in 1838. More recently, the contributions of Mr. William King, late curator of the Newcastle Museum, and of Mr. Richard Howse, to the “ Annals of Natural History” have illustrated several of our rarer species. The excellent papers of Dr. Johnston on the Mollusca of Berwick Bay, published in the “Berwickshire Club Proceedings,” may also be mentioned as coming’ partially within the limits of this Catalogue. So much having already appeared in this department, it may be supposed that little remains to be done in order to give a complete list of the Mollusca of the two counties. It will be observed, however, that scarcely any notices of the naked or shell-less Mollusca have been included in these contributions, and that in the lists of shells, the minute and less conspicuous kinds, which form a considerable portion of the whole, have been generally overlooked. We have been anxious, too, rather to give the result of our own observations, and to verify by personal observation the species already published, than to make a com- pilation from old materials, did these contain a greater propor- tion of our Molluscan Fauna than they really do. The attention that we have paid for several years to the productions of this coast, together with the kind assistance of our friends, has en- abled us to add largely to the materials already published. The arrangement here adopted is that of Cuvier ; but so much has been done since his time, especially towards the attainment of a knowledge of the animal inhabitants of shells, upon which any arrangements claiming to be natural must necessarily be based, that we have been obliged to make several modifications to meet the requirements of modern science. We are fully aware of the imperfections of many parts of this arrangement as it now stands, but we prefer, in the present transition state of the OF NORTHUMBERLAND AND DURHAM. 99 science, to adhere in the main to some system already established, rather than to introduce changes that may not stand the test of further experience. : A spirit of rigid criticism is now abroad on the nomenclature of natural history, which makes it necessary to examine into the priority of each individual synonym in the genera and species: This we have done to the best of our ability and means; and we must acknowledge the great assistance we have derived in this respect from the excellent little Synopsis of the Swedish and Norwegian Mollusca lately published by Professor Lovén, of Stockholm, entitled “ Index Molluscorum litora Scandinaviz Oc- cidentalia habitantium.” as well as from his obliging communi- cations. Our acknowledgments are equally due to Mr. Sylvanus Hanley for his kind assistance in identifying several of the Lin- neean species; an assistance which his laborious and critical ex- amination of the Linnean Cabinet renders him peculiarly able to afford.* Had there been any work which we could have taken as a text book, our task in drawing up this Catalogue would have been comparatively light, but at present no such work on Bri- tish Mollusca exists, though the desideratum is in the course of being supplied by the “ History of British Mollusca and their Shells” by Professor E. Forbes and Mr. Hanley, one or two parts of which have already appeared; but as it will not be completed for three years, we shall not be able to avail ourselves of it on the present occasion. As our Catalogue is exclusively confined to the Mollusca, three classes of Testaceous animals that have usually appeared in British works on shells do not find a place in these pages ; these are, the Foraminifera, the Oirrhipoda, and the Yestaceous Annelida. Modern investigations have proved that these belong to entirely different departments of the animal kingdom, to which they must now be assigned—the first to Zoophytes, the second to Crus- tacea, and the third to Annelida. * Mr. Hanley is about to publish the results of this examination in a work exclusively devoted to the species preserved in the cabinet of Linnzus, the value of which every naturalist must appreciate. 100 CATALOGUE OF THE MOLLUSCA But if our Catalogue exclude some of the objects usually asso- ciated with the Mollusca, it will, on the other hand, be found rnore than usually extensive in two classes, which have seldom obtained a place in our local lists, namely, the MVudibranchiata and the Z’wnicata. In the latter so little has hitherto been done that, even with the kind assistance of of our friend Professor Hd- ward Forbes, we have found the greatest difficulty in referring our species to any of those already described, and it has conse- quently become necessary to publish descriptions of many of them. The coast over which our observations extend, is in some re- spects not particularly favourable for the production of molluscous animals; possessing none of those sinuosities and sheltered bays within which these animals generally find the conditions most favourable to their development. The coast line of Northum- berland and Durham is, on the contrary, bare and exposed, and the sea beats upon its shores much more roughly than in most of the localities celebrated for their marine productions. It is nevertheless not without some advantages. Its extensive sands are unmixed with shingle, and consequently afford a suitable habitation for many bivalves ; which, however, are nearly ex- tirpated on some of the most frequented parts of the coast, From the nature of the strata, too, the rocks do not dip very ab- ruptly into the sea, but run out at a very slight inclination, leaving a great extent of surface at low tides, accessible to the naturalist, and not unproductive of marine animals. In the inland portion of the country the surface is a good deal diver- sified, but upon the whole it is rather too hilly, particularly in the western parts, to be very productive of the land and fresh- water Mollusca, which are generally thinly scattered in upland and exposed situations. The vallies, however, produce not an incon- siderable number of the land species: these abound most on limestone, and a few species are nearly confined to that descrip- tion of rock. Owing to the small extent of marshes and ditches, in addition to the lower temperature, the fresh-water species are much less abundant here than in the south of England. The generalizations of Professor E. Forbes, in his able Paper on the Northern Drift, published in the “ Memoirs of the Geological OF NORTHUMBERLAND AND DURHAM. 101 Survey of Great Britain,’ have demonstrated the use of local Faunas like the present, in furnishing materials for working out some of the most interesting problems that Natural History af- fords ; but for the true solution of problems of this kind, it is not only necessary that local Catalogues should be as complete as possible in the productions of the district, but that care should also be taken not to introduce species by mistake, or on imper- fect evidence, which might give a false idea of their geographi- cal range, and vitiate the generalizations founded upon them, Impressed with this conviction, we have been particularly care- ful in scrutinizing the earlier published Catalogues, and com- paring them with the geographical limits of species as far as already known ; in doing this, we have been led to reject some species only found in a dead state, which deference to previous authori- ties might otherwise have induced us to retain. One source of error, which, without great care, is likely to vi- tiate our Fauna, is the quantity of shells brought in ballast by the coal ships. This ballast, dredged in the rivers and harbours of the south of England, is, in consequence of the dues payable for its deposit on shore, frequently cast overboard at sea, and shells from it are occasionally washed up on the adjoining sands. We have endeavoured to ascertain as far as possible what shells are attributable to this source, but we cannot be sure that in every case we have succeeded. The exposed nature of the coast is not favourable to the use of the dredge, and consequently very few explorations have been made with that useful aid to the naturalist. Our own exploits in that way, we must confess to have been nearly complete failures, owing principally to our inability to stand the exposure and mo- tion of an open sea. Mr. King and Mr. Howse have made at- tempts at deep water dredging, on the cod-fishing grounds at a considerable distance from the shore, the results of which have appeared in the “Annals of Natural History.” Though these can scarcely be called successful, there cannot be a doubt that under more favourable circumstances excellent results might be ob- tained from deep-water dredging off our coast, but the expense and discomfort of the undertaking, as prosecuted in the fishing 102 CATALOGUE OF THE MOLLUSCA ‘boats, together with the great uncertainty of the weather when the grounds are reached, are drawbacks which will prevent its being often attempted. A trial made by Mr. Howse of dredging in fifteen to twenty fathoms water, undertaken for the purpose of gaining information for this Catalogue, has been attended with better success, as the notices of species obtained by it will shew. The Molluscan Fauna of the coast of Northumberland and Dur- ham partakes, as might be expected, much more of the characters of that of northern Europe than of more southern latitudes. On comparing it with the “Index Molluscorum” of Lovén, we find that about half the species of our Catalogue are inhabitants of the Scandinavian shores, whilst scarcely a fifth part are to be found in the Mediterranean. In both cases the greater proportion are bivalves. Dr. Philippi enumerates about one hundred and fifty* marine species, common to Britain and Sicily, but not more than a third of them reach our north-eastern shores, and it is curious that none of the latter are really southern forms, they being near- ly all of a cosmopolite character and equally common to the north of Europe. Compared with the British Fauna our coast affords more than half the number of species found on the shores of Great Britain and Ireland. The species most characteristic of our locality are,— Bullea pectinata,, Natica Montagui, quadrata, helicoides, Bulla Cranchii, Groenlandica, Amphisphyra hyalina, Margarita helicina, Fusus Norvegicus, Nucula tenuis, Turtoni, Modiola nigra, Islandicus, Astarte compressa, Barvicensis, Nera cuspidata, Velutina plicatilis, Panopzea Norvegica.

OF NORTHUMBERLAND AND DURHAM. 103 Fusus antiquus and gracilis, Cyprina Islandica, and Modiola vulgaris, from their size and frequent occurrence, form a conspi- cuous part of our Fauna, but their general diffusion through most of the British seas prevents our considering them as charac- teristic of this locality. These species, however, are rare on the southern coast of England. Of northern forms, whose absence is deserving of remark, perhaps the most conspicuous is Lottia testudinalis, so widely spread in northern latitudes and abundant on many parts of the west of Scotland, as well as in Ireland and Wales. This species does not appear to inhabit any part of the eastern coast of Britain. Other northern species, not uncommon on the western shores of Scotland, are also absent here ; of these we may mention Lima hyans, Terebratula caput-serpentis, Cra- mia anomala, Pecten niveus, and nebulosus, Leda pygmea and Margarita carnea. The following south of England species do not occur with us,— Bulla hydatis, Ovula patula, Eulima polita, Fissurella reticulata, Scalaria clathratula, Calyptrea Chinensis, Truncatella Montagui, Modiola Gibbsii, Tanthina fragilis, Arca lactea, Rissoa crenulata, Cardium aculeatum, striatula, exiguum, Phasianella pullus, Cytherea chione, Trochus umbilicatus, Tellina depressa, striatus, Petricola irus, crassus, Pandora obtusa, Pleurotoma gracilis, Galeomma Turtoni, septangularis, Gastrochena pholadia, purpurea, Pholas parva, Fusus muricatus, papyracea, Erato levis, dactylus. These may all be considered southern forms which have not reached our limits, but it is worthy of remark that some of them attain a much higher latitude on the western side of Great Bri- tain than they do on the eastern. Many others might be added, 104 CATALOGUE OF THE MOLLUSCA but our object at present is only to point out the most charac- teristic forms. The absence of a few species of more extensive range may be accounted for by the exposed character of the coast. Our Catalogue contains altogether 394 species, divided as fol- lows :— Cephalopoda... oi eee he ccmenrere 6 Gasteropoda— Nudibranchiata, ......... 44 Pellibranchiata,............ 1 Inferobranchiata, .........

We have adopted the divisions of Professor EH. Forbes, contract- ing a little their limits, the better to adapt them to the condi- tions observable on our coast. They are as follows :— 1. Lirrorat Zone.—Between high water-mark and the low water of ordinary tides. 2. Laminarian Zone.—Between low water and 12 fathoms. 3. CoRALLINE Zonz.—From 12 to 30 fathoms. 4. Reaton or Deze Water.—30 fathoms and upwards. OF NORTHUMBERLAND AND DURHAM. 105 MM. Audouin and Milne Edwards, who first proposed the dis- tribution of marine animals into zones of depth,* have adopted much smaller divisions, and it would be easy to point out the limits of species, especially between tide marks, within much more contracted bounds, but the above broad and well-marked - features are sufficient for our present purpose. Those species which from their numbers give a character to the zone, we have denoted by italics ; those which from their rarity or partial dis- tribution in Britain give a character to the locality, are distin- guished by small capitals.

Ob- serving some capsules separately attached by short footstalks to a stone, brought in by the fishermen at Cullercoats, we carefully detached them with a penknife, and placed them in a phial of sea water. On taking a magnifier to examine our capture, we found several little Sepiole swimming briskly through the water in all directions, and the capsules lying empty at the bottom of the phial. The little creatures appeared to be of a blueish white; but, on looking again, about a minute afterwards, we found that 108 CATALOGUE OF THE MOLLUSCA two of them had changed to red, and others were rapidly under- going the same process. The change of colour in the cuttle fish tribe is well known to naturalists, and we, ourselves, had witness- ed it partially in some of the larger species, but so sudden and complete a change appeared like magic, and we set about ex- amining the process by which it was accomplished. The white in- dividuals, we found, on looking more closely, were covered with minute spots, which appeared black from the concentration of the colouring matter, but at the will of the animal, or some other ex- citing cause with which we are unacquainted, they gradually en- larged until they spread out into circular red blotches, the edges of the adjoining ones nearly touching each other, and thus chang- ing the general colour of the animal tored. By an inverse process the colour was again changed to white ; becoming red and white alternately several times during the day. Unfortunately they did not long survive. The young Sepiole on first bursting from the egg, appear to have the form and habits of the adult animal, with the exception that the tentacles are then not longer than the surrounding arms. The ink bag contained ink, which was ejected by some of the individuals before dying. 3. LOLIGO, Lamarck. 1. L. vunearis, Zam. (Common Calamary). Sepia loligo, Penn. Brit. Zool. iv. 53, t. 27, f 43.

It is similar to a specimen from Torbay, preserved in the British Museum, and labelled Idalia elegans, by Dr. Leach. There may be some OF NORTHUMBERLAND AND DURHAM. 113 doubt, perhaps, whether it is the J. elegans of Leuckart. It differs from J. aspersa in having five rows of filamentary appendages, as well as in their greater length, and in the slender form and un- equal length of the branchiew, which in J. aspersa are stout and equal, forming a regular rosette.

We lately obtained a specimen of this species alive on the 140 CATALOGUE OF THE MOLLUSCA spines of an Echinus at Cullercoats, but rather injured, and in 2 very sickly state. We placed it in a glass of fresh sea-water, “oping that it might recover, and display itself more distinctly ; but in this we were disappointed, as it soon died, and being left unlooked at for a while had partially decayed. The animal was white, had a rather large foot, without operculum, and a rounded head with two cylindrical tentacles, and minute eyes at the (ex- ternal or posterior) base. No portion of the shell was covered by the fleshy parts, but we are not prepared to say that, in a state of vigour, the animal has not the power of extending some part of the mantle or foot overit. In these particulars it does not differ much from the Stylifer described by Mr. A. Adams, from the coast of Borneo; but we cannot agree with Mr. Gray in plac- ing this genus in the family Maticide, as the very large and pe- culiar disc in front of the head in Natica is entirely wanting here. The animal has much more the appearance of an Hulima.* The remains of the animal examined under a microscope did not show any denticulated tongue. 45. EULIMA, Risso. 1. E. pistorta, Desh.

The animal has two long subulate tentacles, with very large eyes at their posterior base ; the foot is slender, much produced in front, and has a bilobed flap (the mentwm of Lovén) on its upper surface. The body is yellow, beautifully variegated with carmine, which forms an irregular band on each side ; the ten- tacles and foot, white. These are the prevailing colours of the genus, but the disposition of them is different in different spe- cies, and appears to be sufficiently permanent to be taken as a specific character.

Howse, off Whitburn. The animal is white with two long subulate tentacles, ap- proximating at the base, with the eyes immediately behind them. The foot extends a good deal before the head, and has a bilobed flap on the upper surface in front, which appears to be common to the genus, as we have observed it in all the British species. The head is seldom protruded beyond the shell, which, being transparent, the animal can easily see through. Two species appear to be included under the name of Z#. swbw- lata. 'The shell figured, and described by Donovan, which is much larger than this, and has several bands on the body whorl, is rare. It ought to retain the name of F. subulata, and is also the Melania Cambessedesii of Payraudeau. The smaller and much more common species has only two bands, placed close together in the centre of the body whorl, with oc- casionally a faint indication of another on the upper or lower margin. ‘The shell is thinner and more transparent than in the larger species, the whorls less oblique, the lower one a little more ventricose, the aperture not so much contracted, and the columellar margin not quite so straight. This is probably the species called #. lineata by Mr. Sowerby, whose name we adopt, though we would gladly change it to bzlineata, the better to ex- press its distinguishing character. A species in the British Museum, from Madeira, comes very near to this, but has only one band. 46. SCALARIA, Lamarck. 1. S. communis, Lam. Turbo clathrus, Mont. Test.

Hist. xix. 311 (Zulima afinis, Phil 2), but it is rather smaller, flatter in the whorls, and the apex is not so much produ- ced, in consequence of the first whorl being a little more sunk in 144 CATALOGUE OF THE MOLLUSCA the second. It has been got in the south of England by Mr. Jef- freys, Professor E.

We have, therefore, thought it neeessary to insert a description. Two specimens of this interesting addition to our Fauna have been found at Whitburn by the Rev. G. C.

Hist. xiv. 412, it OS Two specimens have been got from the fishing boats at Whit- burn, by the Rev. G. CO. Abbes, and one by Mr. R. Howse, who has also dredged it alive in seventeen fathoms water at the same place. This and the preceding species have been referred to Hulima, and Professor E. Forbes has more recently proposed for them the genus HLulimella, but we prefer considering them to belong to Chemnitzia, from which they only differ in the more polished surface of the shell. The apical nucleus, and the form of the aperture, indicate their place in this genus, independently of the animal, which, according to our observations, is essentially the same in each. 48.

Much misunderstanding exists with respect to this species and the Turbo plicatus of Montagu, which no two conchologists, ex. cepting where one has copied the other, have described alike- The description of Montagu is sufficiently characteristic of our shell ; but Dr. Fleming reverses the two, with the remark thaé OF NORTHUMBERLAND AND DURHAM. 145 “the descriptions had, by some accident, been intermingled in the Testacea Britannica.” Specimens sent by Dr. Turton, under the name of 7. unidentatus, and now in the Newcastle Museum, we find to be O. pallida, though his description in the Con- chological Dictionary is correct, being a copy of Montagu’s. The species described by Mr. Hanley under this name, in the Zoological Proceedings, and in Thorpe’s “ British Marine Conchology,” is, as he informs us, the Awricula conoidea of Philippi ; his Odostomia plicata being our O. unidentata. The O. unidentata of Mac- gillivray, and the figures given by Capt. Brown of his Jaminia unidentata, do not appear to belong to this species. A variety, if not a distinct species, is found on our coast, ra- ther narrower and more rounded at the base, and with a larger umbilicus. As we have only met with two rather worn exam- ples, we shall not attempt to decide upon it at present. 2. O. turRita, Hanley. Odostomia turrita, Hanley in Zool. Proc., 1843. Thorpe’s Brit. Mar.

Our shell agrees with the outline figure given by Professor Lovén in the “ Ofversigt af Kongl. Vetenskaps-Akademiens Forhandlingar,” 1846, t. 1. f 11. It is broader and less turreted than the last. Both species have the tooth very small. There is yet another shell, which we find at Tynemouth, nearly allied to these two, and to O. plicata, though apparently dis- tinct. It is intermediate in form between O. turrita and O. albella, and has a stronger tooth. The species of this difficult genus are extremely perplexing, and require a careful study, to which their rarity, especially in a living state, presents a great obstacle. 4. O. patuipa, Mont. VOL. I.

The figure given in the Annals of Nat. Hist. xii. t. 8, f 13, is deficient in not displaying these characters. From the minuteness and tran- sparency of the animal, the folds of the tentacles can only be seen in favourable lights. 8. O. IntERSTINCTA, JZont. Turbo interstinctus, Mont. Test.

In a fresh state the shell has the furrows between the ribs more deeply impressed at their termination towards the base of the body whorl, giving the appearance of a line of punctures, with sometimes a fainter one below it. ‘This is not usually seen in sand specimens, and was consequently overlooked by Mon- tagu. A variety is not unfrequently found in sand, which is more produced than the normal form, and may possibly turn out to be a distinct species, but the worn state of shells found in sand is unfavourable to the appreciation of minute characters.

When this species was published in the Annals of Natural History, it was referred to the Rissoa glabra of Brown’s Illustra- tions, but, since that time, we have seen, through the favour of Mr. Barlee, an allied species from the south coast, that more nearly agrees with Captain Brown’s figure, and we have, there- fore, now given this the name of diaphana. It is not a true Rissoa, as we have already pointed out. The peculiar character of the animal requires that it should be raised to the rank of a genus. 50. LITTORINA, Férussac. 1. L. urrrorea, Zinn. (common periwinkle.) Turbo littoreus, Mont. Test. Brit. 301. In shallow pools and on stones within tide-marks, common, especially at and a little above half-tide level. A red variety is not uncommon on some parts of the coast. 2. L. nupis, Maton. Turbo rudis, Mont. Test. Brit. 304. On rocks and in pools near high-water mark, common. Beau- tifully banded varieties (L. zonata, Bean) occur at Newbiggin and Bamborough, as well as on some other parts of the coast. 3. L. Rupisstma, Bean. Littorina rudissima, Bean in Thorpe’s Brit. Mar. Conch. 266. On rocks, bare of sea-weed, at and a little above high-water mark, abundant ; frequently found in crevices on the face of a cliff. The species of this most difficult genus are so extremely varia- ble, and approach each other so closely in the different varieties, that we are unwilling to speak very decidedly concerning them. The present, though very nearly resembling Z. rudis, has the shell always thinner and smaller, and is distinguished from the young of that species by having the columella not go broad, nor so much produced and angulated at the base. It has also the spiral ridges generally very strong and conspicuous; but in this 150 CATALOGUE OF THE MOLLUSCA respect it is extremely variable, and is sometimes quite smooth. It undergoes all the varieties of colour and banding found on the last species, besides which we have obtained, at N ewbiggin, a black, and a tessellated variety, coming so near to Z. tenebrosa, that we hesitate to call them distinct. The latter is generally found in mud, but we are inclined to think that the Turbo tenebrosus, and 7’. jugosus of Montagu are probably the two ex- treme limits that this very variable shell undergoes, 4, L. neauecra, Bean. Intiorina saxatilis, “ Bean,” Johns. in Berw. C. Proc. i., 268. Littorina neglecta, Bean, in Thorpe’s Brit. Mar. Conch. 266. On rocks near low-water mark, bare of sea-weed, but covered with Balani and muscles. The habitat of this little species is different from that of the preceding, being always nearer low-water mark. This, with the difference of form and size, induces us to think it distinct. We have taken from the body of this species, embryos, well developed and covered with a shell —A. ZH. It was first described by Dr. Johnston under the name of saxatilis, given it in manuscript by Mr. Bean. In consequence of this name having been used by Olivi for another species (pro- bably the following), Mr. Bean subsequently changed it to neglecta, under which name he has described it among his new species in Thorpe’s “ Brit. Marine Conchology.” Having omitted to mention that it had been described before, the species appears twice in that work :—viz., under the name of Z. saxatilis, in the Addenda, and of Z. neglecta, in the Supplement. 5. L. petrma, Mont. Helix petrea, Mont. Test. Brit. 403. Turbo cerulescens, Lam. Anim. s. Vert. 2nd Hd. ix. 217. On rocks at and above high-tide level, frequent, especially in crevices of the cliffs, where it nestles in company with L. rudissima, beyond the reach of the sea, excepting the dashing of the spray, and the high water of spring tides. There can be little doubt that the 7’. cewrwlescens of Lamarck, of which we have specimens from two localities in the Mediter- ranean, is a variety of this species, though Philippi, in his description of the animal, does not mention the milk-white OF NORTHUMBERLAND AND DURHAM. 151 band in front of the foot by which our species is distinguished, and his description altogether corresponds more nearly with that of ZL. rudissima. Philippi enumerates seven synonyns of this species, without taking into account our English name, and the Z’urbo neritoides of Linnzeus with which he is now inclined to indentify it. The Turbo ziczac found by Lady Wilson near Sunderland, and stated to differ from the West Indian specimens in wanting the ZICZAC markings, is most likely only a variety of this species ; at least a specimen so named in the cabinet at Wallington, which we had the opportunity of examining through the kindness of the late Sir John Trevelyan, Bart., certainly belongs to ZL. petroed. 6. L. retusa, Lam. Nerita littoralis, Mont. Test. Brit. 467. Littorina neritoides, Johns. in Berw. C. Proc. i. 269. On sea-weeds, among the rocks near high-water mark, common. The Zurbo retusus and 7’. neritoides of Lamarck, are un- doubtedly only different forms of the Nerita littoralis of Lin- nexus, as we have satisfied ourselves by an examination of the Lamarckian specimens. As 7’. neritoides, Linn., is not considered to belong to this species, we adopt the former name. 7’. obtu- satus, Linn., we are assured by Mr. Hanley, is distinct. The Turbo aureus of Brown (Conch. Ilust. 2nd Ed. 17, t. 10, f, 23), found by Sir Walter C. Trevelyan, Bart., at Seaton, Nor- thumberland (qu. Durham 2), is referred in the appendix to the genus Margarita, and in the description of the plates is called a LInttorina. We think it scarcely belongs to either of these genera. 51.

We cannot find any permanent character to distinguish these three supposed species of Montagu, and have therefore united them. The shell is extremely variable both in form and mark- ings. The more elongated form, both banded and unbanded (T. vinctus, and 7. canalis), is rare, but the short, banded va~ riety (7. quadrifasciatus) is abundant on the fronds of Lami- naria digitata, at and beyond low-water mark. 4.

The shell is thicker and more slender than JZ. vincta, and is somewhat intermediate between it and L. crassior. It agrees very well with Professor Lovén’s description, but is smaller, and, as we have not seen authentic specimens, we cannot speak with certainty of the species to which we have referred it. It appears, however. to be distinct from any of the other British Lacune. 5. L. crassror, Jont. Turbo crassior, Mont. Test. Brit. 309, t. 20, f. 1.

It is sometimes brought up pretty plen- tifully in the trawl-nets by the fishermen at Cullercoats. The animal, from its broad proboscidiform head, and short lateral tentacles, bears a great resemblance to Cerithium. It is very shy and sluggish, and will lie for days together without shewing itself beyond the mouth of the shell, or attempting to crawl about. Faminy. Cerirarape, Mleming. Cerithium reticulatum, Da Costa, has been frequently found on OF NORTHUMBERLAND AND DURHAM. 155 the shore near Sunderland and Whitburn, by the Rev. G. C.

Perhaps from the same source as the last. Cerithium fuscatum, Brown ( Turbo tuberculatus, Penn. Brit.

Cerithium cancellatum, Brown (Illust. Rec. Conch. 2d Ed. 9, t. 5, f. 64), is also stated to have been found “on the Northum- berland coast at Holy Island.” We do not know it, but are inclined to think that none of the Cerithia are indigenous to our coast. The Strombus costatus of Sir C. Sharp’s list is also a Cerithium, but it is now generally believed that this shell, common in fo- reign collections, has been introduced into the British Fauna by mistake. The shell found at Hartlepool was most likely Ceri- thium reticulatwm. 56. APORRHAIS, (Da Costa) Dillwyn. 1. A. PEs-PELECANI, Linn. Strombus pes-pelecant, Mont. Test. Brit. 253.

Murex corneus, Mont. Test. Brit. 258. Fusus Islandicus, “ Martini,” King in Ann. Nat. Hist. xviii. 246. In the coralline and deep-water zones, frequent. The variety from deep water is more ventricose than the common form, and has the epidermis thinner, smoother, and sometimes of a reddish colour. The shell figured by Captain Brown in his “Illustrations of the Recent Conchology of Great Britain,” t. 6, f 11, 12, found by Sir W. C. Trevelyan, Bart., at Seaton, appears to be an un- usually short specimen of this variety. Much confusion has arisen in the name of this species from the circumstance of Linneus having included more than one shell in his Murex corneus; but as it is now agreed that the name should belong to the Mediterranean shell (Pusus lignarius of Lamarck), and being of opinion that our species is not the /usus Islandicus of Chemnitz, to which it has lately been referred, we follow Professor Lovén in adopting Da Costa’s name, the earliest undisputed appellaticn. 5. F. PROPINQUUS, 2. s. Shell fusiform, white, covered with a brown epidermis, striated spirally ; the strie rather variable, but generally deep and dis- tant on the upper whorls, more closely set on the lower, and often rising into ridges towards the base of the shell. Whorls 8, flattish, or very slightly convex, and a little tumid above at the suture ; they are broader in proportion to their height than in the last species, and consequently the spire is a little less pro- duced. The nucleus, forming the apex of the shell, consists of two or three very small whorls, the first very little raised, and only to be seen from above; the apex is rather slender, not mammillated, and generally stained of a ferruginous colour ; aperture oval, rather contracted, and ending in a short canal of moderate width, a little bent towards the left side ; outer lip thin ; pillar smooth, a little arched inwards in the centre, and produced in old shells into an obtuse rounded angle towards the entrance of the canal. Length 14 in., breadth $ in. 158 CATALOGUE OF THE MOLLUSCA A variety from deep water is shorter in the spire, and more tumid in the body whorl, and has the canal very much twisted to the left side. The epidermis is thin, pale yellowish horn- coloured, and hispid. The apex is frequently incrusted with black. Animal white. Found in the same situations with the last, but rare. This species very much resembles /’. gracilis but never grows to half the size, and may readily be distinguished from it by an examination of the apex. The nucleus of /. propinquus con- sists of two or three small compact whorls, while that of F. gra- cilis has only about a whorl and a half, which are large, and rather produced at the top, giving the apex a mammillated ap- pearance. The embryos of these two species must, therefore, dif- fer as much from each other as those of #. Turtont and /. Nor- vegicus. The shell of /. propinquus is rather more tumid, and the whorls rather flatter in the middle, and more raised towards the suture than in 7’. graciiis: the striz also are closer, the aper- ture more contracted towards the canal, and the latter a little more bent. The variety from deep water, dredged by Mr. Howse in sixty fathoms, has much the aspect of a distinct species, but a shell in that gentleman’s possession seems to unite it with the normal form. Mr. Howse has figured the variety in the Ann. of Nat. Hist. vol. xix., t. 10, fi 5. 6. F. Isnanpicus, Chemn. Fusus Berniciensis, King in Ann. Nat. Hist. xviii. 246. Tritonium Islandicum, Lovén Ind.

They were 284 A CENTURY OF UNRECORDED LOCAL COLEOPTERA. living in apparent harmony with great numbers of Hylobius Abietis, and, like them, were feeding on the soft juicy bark of the young trees and branches. JI found them, in almost every case, on the underside of the trees or branches, and they appeared to prefer those lying amongst grass in damp places. The sexes are similar in appearance, excepting that the male has the rostrum shorter and stouter, and, with the thorax, more roughly punctured than in the female. The male is also generally smaller than the other sex, but both vary much in size, some specimens being as large again as others. Recently developed individuals are pale coloured; one that I dug out of a stump of Scotch fir, on the 22d of July, was softer, of a paler ferru- ginous, and had the scaly bands and spots much darker coloured than the generality of specimens. As above mentioned, I found them first in May, but by no means common ; they were most abundant in the beginning of June ; in July they were scarce ; and by the middle of August, became so rare, that I relinquished searching for them. Specimens have also been found at Dinsdale, by Mr. W. Pea- cock ; at Gibside, by Mr. T. Pigg ; and recently I had a pair brought me, which were found on Sunderland Pier. 88. Doryromus agnaruos, Dahl.

By Raueu Carr, Esq.* [Read May 18, 1848.] Tux latter part of summer, and the beginning of autumn in 1847, were remarkable, it will be recollected, for a long-pro- tracted drought. In the last week of September, I happened to be engaged in marking for the axe, a number of trees that were to be taken out of a plantation at Hedgeley, which, being then of the age of 19 years, required to be thinned for the third time. It formed a compact mass, occupying about eleven acres, upon a light surface-soil, under which lies, in many places, a substratum of clay, not unfavourable to the growth of oak. The species which I had planted were chiefly the last-named tree, to come forward as a permanent crop, accompanied by some Sycamore, and a liberal sprinkling of Birch. The nurses were Larch and Spruce Fir. The Larch had already begun to show symptoms of heart-rot, a disease to which that species is more peculiarly liable on land that has been recently under the plough, as had been the case with more than half of the surface in this instance, * Mr. Carr’s paper was not received in time for insertion in its proper place. 286 ON EXTENSIVE FISSURES OBSERVED The Spruces, in most parts, had grown better than could have been expected on such light land, and were evidently more to be relied on than the Larches, although upon land of this descrip- tion not many of them could be expected to live to the age of full maturity, since the species requires either a strong soil, or otherwise a very regular and equable supply of moisture in the ground on which it stands. Under such circumstances, my ob- ject whilst thinning the plantation, was, first, to open out the Oaks, and next to give a preference and free space to the Spruces, in order that they should continue healthy as long possible, and especially that the vitality of their lower branches, so essential to the vigour and beauty of this tree, should not be destroyed, by exclusion from the air, the light, and the dew. It was neces- sary, therefore, to examine a vast number of Spruces indivi- dually and closely, to determine whether each was worthy of having some neighbouring Larch condemned to fall, in order to afford it room. After having gone over good part of the ground in this man- ner, I was much surprised to discover two Spruces (the Huropean Abies excelsa,) most singularly rent, almost from end to end of their stems, by a series of wide and extensive fissures, just as we see in the case of Larches that have been felled, peeled, and left exposed to the sun. The diameter of these two trees, at the lower end, was greater than that of a man’s thigh, yet the open- ings seemed to penetrate nearly to the centre of the wood. Strange to say, vegetation was in full vigour, there was not the slightest symptom of injury from lightning ; not a single spine- let of foliage was scorched, not a splinter along the course of the cracks was ruffled or displaced. Frost, in the preceding winter, could not have been the agency, for the fissures were as fresh as if I had opened them that very hour by means of a wedge ; nay, they were probably even then extending themselves. To attri- bute the effect to wind was impossible. In the first place, there had been no violent gales for a long time ; then, the Spruce Fir is a plant so accurately balanced by its form, that it can never suffer from the screwing motion which sometimes gives rise to the rending of the Ash, or Wych Elm during gales. Above IN TWO HEALTHY TREES. 287 all, the plants in question stood near the centre of the planta- tion, exceedingly well sheltered. Could the long drought have been the cause of an appearance, which, so far as my experience has gone, must be rare in our climate? This seemed more pro- bable. Yet even against this solution of the difficulty there were some considerations not to be neglected. First, the spot, where these two Spruces and many others grew, was one of the best in respect of soil, within the limits of the plantation, and it was na- turally always rather moist, though not with stagnant water. The soil is of considerable depth, black, and of the nature of ancient peat or forest-soil, and, not having been under the plough, was always covered with a fresh green herbage. It was the most unlikely spot of all to be deprived entirely of moisture by the long drought, though doubtless it had reached a very un- usual degree of dryness. Again, I happened to remember that in the preceding month of May, I had cut out a number of Larches, and several Spruces also, from a distant part of the same plantation ; that the Larches were immediately peeled and left lying in the shade, whilst the Spruces had been carried out, in their bark, and laid together on the south side of the wood- land, so that they must have been exposed all summer to the sun. I was very curious to see whether these poles of Spruce had been cracked or “galed” by the heat and exposure. On going to the spot I found them lying as I expected, but without a single fissure. The Larches, though lying well shaded, were a good deal rent. I may now add, two years subsequently, that the health and vigour of the two Spruces in question has continued without any check. They are thriving as well as any of their neigh- bours. The fissures are superficially almost all closed. The lower branches, as well as those higher up, continue alive and healthy, and still clothe and protect the stems from excessive evaporation, as they did at the time of the injury. On the whole, it seems to me difficult to infer that drought could be the primary, or, at least, the only cause, of this occur- rence, to two trees only out of so many, and those but little ex- 288 ACCOUNT OF A RIBBON FISH posed to the sun or to the air. So little is known of the action of electric and magnetic streams, in connection with the phenome- na of vegetation, that to refer what we cannot otherwise explain to their agency, with any degree of positiveness, would be ab- surd. Yet I think it more than probable that the ordinary course of the sap must have suffered some temporary and partial interruption or derangement, from some powerful, though ob- scure, cause, before such an unequal contraction of the woody tissue could occur, as to rend its whole substance so extensively. I hope, on some future occasion, to exhibit before our Club, cross sections from the stem of one of the trees, which I intend to fell, to obtain them, whilst its fellow shall live on. It is probable that in the spruce forests of Switzerland and Scandinavia, where the summers are both hotter than ours, and electricity often more active, such instances of living trees open- ing in fissures, may be well known. They may indeed be fami- liar to the owners of large resinous woodlands in our own country. Ifso, perhaps we shall receive authentic information on a subject of considerable interest. Oct. 5) 1849. XI.—Account of a Ribbon Fish (Gymnetrus) taken off the Coast of Northumberland. By Ausany Hancoox and Dennis Emu- BLETON, M. D., Lecturer on Anatomy and Physiology, in the Medical School of Newcastle upon Tyne.* [Read at the Anniversary Meeting, April 21, 1849.] Qn the 26th of March, 1849, a fine specimen of a species of Gymnetrus, or Ribbon Fish, was captured by Bartholomew Tay- * By the kindness of R. Taylor, Esq., F'. L. S., the Club has been supplied with copies of the plates which illustrated this paper in the Annals and Maga- zine of Natural History for July, 1849. TAKEN OFF THE COAST OF NORTHUMBERLAND. 289 lor and his two sons, the crew of a fishing coble belonging to Cullercoats. It was found at about six miles from shore, and in from twenty to thirty fathoms water. The men having started from their fishing ground to return homewards, observed at a little distance what appeared to be broken water ; the old man being struck with such a novelty directed his lads to pull towards it ; on nearing the spot they perceived a large fish lying on its side on the top of the water. The fish as they approached it righted itself, and came with a gentle lateral undulating mo- tion towards them, showing its crest and a small portion of the head occasionally above water ; when it came alongside, one of them struck it with his picket—a hook attached to the end of a small stick, and used in landing their fish ; on this it made off with a vigorous and vertical undulating motion, and disappeared, Taylor says, as quick as lightning under the surface. In ashort time it re-appeared at a little distance, and pulling up to it they found it again lying on its side ; they plied the picket a second time, and struck it a little behind the head ; the picket again tore through the tender flesh by a violent effort of the fish, which escaped once more, but with diminished vigour ; on the boat coming a third time alongside, the two young men putting their arms round the fish, lifted it into the boat. Signs of life remained for some time after the fish was captured, but no doubt it was in a dying or very sickly state when first discovered by the Taylors. It was exhibited the same day at Tynemouth, North and South Shields, and brought to Newcastle next morning. In the afternoon we first saw it; we found it much injured by the strokes of the hook and by rough handling during its removals and the examinations it had undergone. The fins were a good deal torn, but the fish was evidently quite fresh. Its colour was a uniform silvery gray all over, resembling bright tin-foil or white Dutch metal, except afew irregular dark spots and streaks towards the anterior part of the body. On closer inspection the remains of a bright iridescence was seen about the pectoral fin and head, the blue tint predominating. External description.—The fish presents somewhat the form VoL. I. Qq 290 ACCOUNT OF A RIBBON FISH of a double-edged sword blade, being excessively compressed ; its greatest thickness is decidedly nearer the ventral than the dorsal border ; from the thickest part it slopes gradually to each border, the dorsal being the sharper. The length of the fish is 12 ft. 3 in., the mouth not being projected forward ; immediately behind the gills it measures 83 in. in depth ; from this point it gradually enlarges to a distance of upwards of two feet further back, where it attains its greatest depth of 111 in. ; this dimen- sion remains much the same for 13 ft. beyond ; it then gradually but perceptibly diminishes to the end of the dorsal fin, where the depth is 3 in. The thickness through the head at the gill-covers is 2 in., at the part of greatest depth 22 in. ; Plate I. fig. 2 shows a section at this part. Opposite the anus somewhat less ; it then gradually diminishes to the end of the dorsal fin, where it is upwards of three-eighths of an inch, fig. 3. The fishermen state that when this fish was first taken it was all over of a brilliant silvery iridescent hue, resembling in inten- sity that of the fresh herring, which soon faded, and shortly after we saw it, all traces of the iridescence except those already men- tioned had disappeared. The skin is covered over with a silvery matter in which no scales are visible to the naked eye, but which is most readily detached from the skin and adheres to anything it comes in contact with. Submitted to the microscope it is found to consist partly of minute convex scale-like bodies of elongated pyramidal outline with the base rounded, Pl. I., fig. 4, which are formed of fine clear crystalline-looking filaments, ar« ranged side by side, and radiating from the apex to the base of the scale; these filaments grow much finer towards the base, where a number of minute granules are also observed. The scales remind one of some of those seen on the wings of moths. The bulk of the silvery matter of the skin, however, is made up of a soft matter finely granular, and presenting numerous trans- parent fragments of what have the aspect of acicular crystalline bodies. We have not been able to detect the mode of arrange- ment of the scale-like bodies on the skin. Round the posterior margin of the preoperculum is a broadish dusky mark on the TAKEN OFF THE COAST OF NORTHUMBERLAND. 291 skin, and near the top of the head above the eye a crescentic mark of a dark iridescent blue colour ; besides these there are on the side of the body several narrow, dusky black, slightly waved lines considerably apart from each other and obliquely inclined from before backwards ; of these eight or nine are above the lateral line and of unequal length ; below the same line they are more numerous, diminishing in size on the whole till they end in mere spots at some distance behind the anus. The lower series seems to correspond in some measure with the upper. In- terspersed among the lines are a few irregular spots of the same hue towards the head. The dorsal and ventral ridges are also dusky. The lateral line was at first smooth and very distinct, but after the fish had been a few days in Goadby’s fluid, elon- gated flat scales became apparent on the line ; it can be traced from the back part of the head above and behind the eye, sweep- ing down gradually to within 34 in. of the ventral margin at 18in. from the snout ; at the anus it is 2 in. from the margin ; it thence runs backwards, still approaching the margin, to the caudal extremity. Four longitudinal flattened ridges, each rather more than | in. broad, extend from the head to the tail immediately above the lateral line, which cuts them off very obliquely in front ; the uppermost, which is the longest, running forwards almost to the eye. The surface of the skin of the body is studded with very nu- merous distinct and separate tubercles of bone ; the smallest and most depressed lie between the ridges and towards the ventral and dorsal margins, the largest, and most elevated upon the ridges, some of these last being =; in. in diameter. On the ven- tral ridge are numerous, irregular, and prominent tubercles slightly hooked backwards. The tubercles present no regular arrangement, they are imbedded in the skin, and it is difficult to say whether or not they had been covered by the silvery matter of the skin ; when we examined them, their apices were uncover- ed by it. Some were observed to have a perforation at the apex which was occupied by a soft papilla. The tubercles are replaced 292 ACCOUNT OF A RIBBON FISH in the neighbourhood of the head by irregular depressed indu- rations of the skin. The head is small and short, measuring 9 in. from the snout to the posterior margin of the gill-cover ; the outline of the lower jaw is a wide arch convex below, and stretching forwards and upwards to the mouth, which is placed in an elevated posi- tion and opens upwards and forwards ; the mouth is small, near- ly circular, and capable of being projected 2 or 3 in. forwards when the lower jaw is depressed. The profile of the head from the anterior end of the crest is at first suddenly concave, the con- cavity facing forwards and upwards, and just behind the anterior end of the curve exists the nasal chamber which is small, and owing to the damaged state of the fish we could only find one small aperture, which was longer than it was broad. Beyond this concavity the premaxillary bones project nearly horizontally to the mouth. The eye is 13 in. in diameter, the iris of a beau- ful silvery white, and rather broader than the diameter of the pupil. The eye is situated 24 in. below the base of the crest and 13 in. behind the frontal concave profile. There is a narrow im- perfect circle of a dusky colour round the contour of the eyeball. The eye is very flat. The tongue is rather prominent, but small, smooth and fixed. There are no teeth. The interior of the mouth is black. The gill-covers are large in proportion to the size of the head, prolonged backwards, their posterior angles considerably ele- vated. The preoperculum has somewhat of a crescentic form, the lower border convex ; the anterior horn is narrow and pro- longed to its articulation with the lower maxilla, the posterior border has an obtuse angle pointing backwards. This border corresponds to, and may rest upon, the edge of the concavity formed by the operculum above and the interoperculum below. The operculum is on the whole broad and irregularly quadrate, with the upper anterior angle prolonged forwards and upwards ; the upper margin is smooth and slightly concave nearly as far as the angle, it then curves suddenly downwards a little to the angle which is rather obtuse. Below this is the posterior border, TAKEN OFF THE COAST OF NORTHUMBERLAND. 293. which is somewhat sinuous and rather oblique from above down- wards and forwards. The inferior border is nearly straight, and directed upwards and forwards corresponding with the interoperculum. The remaining bone, which we take for the interoperculum, is narrow and thin, prolonged almost to a point under the jaw and widening gradually to its posterior end, which is rounded and projects backwards beyond the preoperculum. Its lower border is convex and lies almost horizontally. These are the only pieces observed as entering into the forma- tion of the gill-covers. The above bones are exceedingly deli- cate and fragile, and present the radiating lines of development with great prominence; the silvery skin covering them is re- markable for its delicacy. The branchiostegal rays are seven in number; the uppermost a broadish plate marked by radiating lines, the rest diminishing successively in size, having the ordinary characters of such rays. The four branchial arches diminish in size backwards, and the pharyngeal is less than the fourth branchial arch. The rays of the convexities of the branchial arches are very numerous; the concavities of these arches are beset with prominent blunt-pointed tubercles which are studded with a number of short sete or bristles, sharp-pointed but rather soft, which project inwardg towards the pharyngeal cavity. The first branchial arch has in addition a row of short pale-coloured rays or plates, the inner edges of which are also furnished with sete which project like- wise inwards. On the roof of the pharynx are two or three pairs of short laminz (pharyngo-branchial) furnished with similarsete, pointed backwards and downwards in the direction of the en- trance to the esophagus. The dorsal fin extends from immediately behind the upper and posterior end of the curved frontal profile to within 3 inches of the tail of the fish. The anterior part of the fin, more promi- nent than the rest, is composed of twelve rays, which were stated by the captors to have been 12 or 14 inches in length when the fish was taken, and to be each furnished with a membranous ex- 294 ACCOUNT OF A RIBBON FISH pansion on its posterior edge, increasing in width upwards some- thing like a peacock’s feather. The first ray is a pretty strong spine arising just within the frontal curve, the three next are very slender, and much closer together than the rest, and when we first saw the fish, united for 4 or 5 inches (their length at that time) by a membrane; the next is as slender as the preceding, but rather farther apart; the three or four after this are nearly as strong as the first, the rest diminish in strength and length, and become uni- form with the rays of the dorsal fin. It is difficult for us to say whether the twelve front rays con- stituted a detached crest or formed merely the anterior continu- ation of the dorsal fin, though after careful and repeated exami- ~ nations we found shreds of membrane in each interval between them, and their bases also were connected with a continuous membrane. In the interval between the twelfth and thirteenth rays the remains of a membrane were found connecting the base of these rays, and their shafts were ragged and woolly looking, as if a membrane had been torn off from them. We are, there- fore, inclined to conclude that the crest was really a continuation of the dorsal fin and not a separate structure, though it is pro- bable enough that the ends of its rays may have been for some distance free and even furnished with a membrane on their pos- terior margin widening to the top, giving them the appear- ance of peacocks’ feathers as asserted by the fishermen. This probability is heightened by the fact of the head of the Gymne- trus from the Cornish coast being provided with two long rays having broad membranous expansions at their ends, which would justify a casual observer in comparing them in form to the above feathers. It is not unlikely besides that the second, third, fourth, and fifth rays, on account of their resemblance in delicacy to the ordinary fin-rays, may have terminated differently from the rest. The rays having been broken, we cannot say of ourselves whether they were uniform in size or not; but from what we have learnt by questioning those who saw the fish, we conclude that the middle rays were the longest, those in front and behind them TAKEN OFF THE COAST OF NORTHUMBERLAND. 295 gradually decreasing in length. The rays of the crest are more closely set generally than those of the rest of the dorsal fin, which stand about half an inch apart. Exclusive of the crest there are 268 rays in the dorsal fin, They terminate in fine points that project a little beyond the margin of the very delicate connecting membrane. This membrane was colourless according to the fishermen, but was bordered by a pale red when we observed it. The rays of the back are highest about the middle of the fish, where they measure upwards of 34 inches, and at the termination of the fin are about one inch in height. From the end of the fin the dorsal margin slopes rather rapidly downwards to within about an inch of the ventral margin, and is then prolonged to a rounded point at the caudal extremity. There is no caudal fin. The skin at this part, it is true, was broken, but on pressing together the broken edges they seemed to leave no hiatus. The fishermen persisted that the part was at first entire, and that there was no appendage whatever. Ata distance from this point of about two inches along the ventral margin there exists a shallow notch. Both the margins of the fish at this part are very thin. On carefully inspecting the sur- face of the body, something like a series of transverse marks cor- responding with the bodies of the vertebra can be discerned, and the number of these has from this appearance been roughly esti- mated at about 110. The pectoral fins are placed close behind the gill-covers, and much nearer to the ventral margin than to the lateral line, which is at least half an inch above the points of the rays of the fins; these fins are colourless, delicate, subtriangular, and the longest rays measure two inches. They are eleven in number, and a good deal arched. The ventral fins are represented by a pair of very strong and straight spines, stated by the fishermen to have been 7 or 8 inches long and as if broken at the end, and furnished along the pos- terior edge with a delicate membrane about half an inch broad. When we saw them they were about 4 in. long, and the mem- brane was distinctly visible at their bases. These spines, which at their root measure about din. in diameter, project from each 296 ACCOUNT OF A RIBBON FISH side of the ventral ridge immediately behind the pectoral fins, are inclined backwards, and capable of a limited lateral and back- ward motion. We are assured by a gentleman who witnessed the landing of the fish, that these spines were bright crimson and resembling the feelers of a boiled lobster ; hence we conclude that they must have been originally flexible towards the end, and much longer than 7 or 8 in. as stated by the fishermen .The same gentleman says that the rays of the dorsal crest were sim- ple and unbordered by a membrane. The whole fish is remarkably delicate and tender, and easily broken when bent laterally, as shown by the injuries it has sus- tained by being lifted in and out of the boat, dc. ; the flesh is white and fine. Internal examination.—On opening the fish, the abdominal cavity, Pl.

IT. figs. 2 & 3a, at first slightly funnel- shaped, soon assumes a diameter of one inch, and then forms a gradually increasing tube as far as the coming off of the duode- num 233 in. below the orifice, where it measures 24 in. in diameter. Nothing like any cardia or line of demarcation between the cesophagus and stomach exists in this tract. The duodenum comes off abruptly as a short tube Id in. in diameter, inclining forwards from the under surface of the stomach. The stomach, fig. 3 6, is continued on beyond the duodenum as a straight tube, gradually diminishing in diameter towards the posterior end of the fish, measuring an inch across opposite the anus. At this point it has the rectum or intestine lying below it, the ovaria and ureter above, the oviduct and ureter running down to the anus on its right side. It is slightly contracted opposite to the anus, and a little be- yond this enters a canal among the muscles, a continuation of the abdominal cavity, situated at about 1Jin. from the ventral margin and with tendinous walls, to which it is pretty firmly adherent throughout. It is enlarged slightly after entering the canal, and then diminishes gradually from the diameter of rather TAKEN OFF THE COAST OF NORTHUMBERLAND. 297 more than an inch to the size of a crowquill. It can be traced backwards to within Ift. 8in. of the caudal end of the fish, gradually approaching the ventral border, and terminating in a blunt blind extremity, Pl. II. figs. 2 & 3c. Thecanal, in which the cecal prolongation is lodged, is prolonged for an inch or two beyond the end of this latter, and contains several small blood- vessels, and the cellular coating of the cecum arranged in cords, the vessels being gradually lost by passing backwards and out- wards into the surrounding muscular tissue, the cellular cords being attached to the sides of the termination of the canal. The anterior main part of the stomach, when laid open, was quite empty, the inner surface of the cesophagus and stomach as far as two inches below the pylorus perfectly uniform and smooth ; from the point here indicated, the upper wall of the stomach presents the gradual beginnings of a few longitudinal plice, on tracing which backwards they are found to increase in number until, at five inches in front of the anus, the whole inner surface of the tube is provided with them. They are continued on in the stomachic cecum to within two or three inches of its termi- nation. At about halfway along this cecum was found a small quantity of the spawn of some fish partially digested, several of the ova being still entire ; a little way in front of these was an angular bit of cinder. The pylorus, fig. 3d, coming off as above mentioned from the most enlarged part of the stomach, extends for only 1}in., when it becomes suddenly constricted, and presents internally the usual circular valve. The duodenum, figs. 2 & 3 e¢, beyond, is a cylinder of about lin. in diameter and 1ft. in length, perforated all round by very numerous circular openings, the orifices of the pancreatic ceca, which measure about 3 inch in diameter and 1 inch in length, and completely mask the whole duodenum. This part of the tube extends forwards, lying parallel to and beneath the stomach, and overlapped by the posterior lobes of the liver for about 4in., and then, emerging as it were from the pancreatic caeca, is continuous with the remainder of the intestine, figs. 2 &3/f f, which then is suddenly bent backwards and runs along the VOL. I. RT 298 ACCOUNT OF A RIBBON FISH. lower border of the pancreas obscured by the ceca of the right side ; and then keeping along the floor of the abdominal cavity, it passes on as a straight tube to the anus, figs. 2 & 3g, at the front of which it opens separately. The diameter of the duode- num is diminished one-half at its exit from the pancreas, and the intestine continues of the same size to within an inch or two of the anus, where it is gradually lessened to about }inch. The length of the intestine from duodenum to anus is 3ft. 5in. The inner surface of the intestine below the duodenum presents a very delicate honeycombed texture, the laminz being fine, of varying size, and crossing each other in all directions, the largest standing up pretty high and taking a longitudinal course. This form of valvule conniventes extends to within three or four inches of the anus. A few inches below the end of the duodenum was observed a delicate and transparent, but large and crescentic, membranous valve, projecting into the cavity of the intestine. There is no division into large and small intestine, unless the above valve point it out. No cecal appendage, except to the stomach. The intestine contained nothing but a quantity of pancreatic secretion. Attached to the upper surface of that part of the intestine which is opposite to the pylorus, is the spleen, fig. 3 4, ovoid in form, delicate and spongy in texture, 2 in. long by j in. broad, and of a very pale reddish brown colour. Large blood-vessels run along both the upper and lower borders of the intestine be- low the duodenum. The liver, figs. 2 & 3 i, is large, and extends 18in. backwards from the anterior end of the abdominal cavity lying below the esophagus, somewhat pointed in front, and becoming more bulky towards the posterior end, where it is truncated diagonally from above downwards and forwards. The upper surface has a deep fissure partially dividing it into two unequal masses, the left being larger than the right; along this fissure run the hepatic and pancreatic blood-vessels ; the gall- bladder and the cystic duct lie also attached to it. The gall-bladder, fig. 3 j, about 5 in. long and 14 in. broad, is of an irregularly elliptical form, its long diameter corresponding. TAKEN OFF THE COAST OF NORTHUMBERLAND. 299 nearly with the length of the fish; the cystic duct comes off from its anterior end, and, running backwards parallel to it and to the hepatic duct, joins the latter just before coming to the posterior border of the liver: the common duct, fig. 3 4, after this runs backwards among the lower appendices pylorice of the left side, and debouches into the duodenum on a small papilla upwards of an inch distant from the pylorus. The gall-bladder contains a small quantity of yellow olive-coloured bile. The texture of the liver is so soft and fragile that it cannot be preserved. The ovaria, figs. 2 and 3 J, lie directly above the stomach, are about 3ft. 3in. long, and extend forwards nearly as far as the middle of the liver. Their ends taper to points diverging slightly from each other ; traced backwards, they gradually increase in bulk to #in. in diameter at their middle; soon after this they diminish in size, become more closely connected, and unite at 27 in. from their anterior points into one body, which tapers gradually to Zin. in diameter, and then curving downwards to the external orifice on the right side of the stomachic cecum, only becomes rapidly smaller, and opens behind the intestine. On lay- ing open the common tube or oviduct, it is found for 2 or 3 in. from the orifice quite plain ; above this, longitudinal folds of the lining membrane appear small and irregular at first, but soon larger, more projecting, and then occupying the whole inner sur- face of the tube. These plicxe, which become tortuous and col- lected into rows of two or three together, are found to extend to the ends of the ovarian cavities, and are studded throughout with minute ova of unequal sizes in an undeveloped state. The ureter, figs. 2 and 3 m, a simple tube of the size of an ordi-~ nary goosequill, runs from the external orifice, just within which is a slight vesical dilatation, fig. 3 7, along the median line, lying above and attached to the ovaria, and in contact with the roof of the abdominal cavity, for a distance of 1 ft. 11in., when it per- forates the fibrous membrane separating the kidney from the other viscera. It runs obliquely forwards and upwards into the kidney, fig. 3 0, which, inclosed in its proper cavity, extends from an inch behind where the ureter joins it as far as the cra- nium, a distance of 2 ft., reaching farther forward than the di- 300 ACCOUNT OF THE RIBBON FISH gestive cavity. The organ is partially and unequally cleft by a median fissure, the left side being larger than the right. Its tissue is reddish brown, spongy and friable. The posterior end of the kidney tapers to a point. The anterior end also tapers a little, but isrounded. The ureter enters the under surface of the gland, and terminates by opening into the general cavity which exists along the median line of the organ. Along the upper angle of this cavity and elsewhere are the openings of small canals bringing the secretion from the uriniferous tubules. These last can be readily seen with a common magnifying glass. The supra-renal glands, fig. 3 p, are two small ovoid bodies, much paler than the kidney, partially imbedded in that organ on its upper surface, at a distance of two inches from its posterior extremity. There is no trace of air-bladder. The heart, which is double the size of that of an ordinary cod- fish, occupies a spacious triangular cavity. Its ventricle is large, firm, and triangular. The bulb of the aorta is smaller than that of the cod. The auricle is capacious and of irregular form. The blood-vessels beyond were not examined, and we could not investigate the nervous system. In a little blood obtained from the heart, the blood-discs, Pl. I: fig. 5, are found to vary much in size, and also in form from sub- circular to elliptical and even fusiform, having their extremities or poles somewhat pointed. The nucleus is generally large and distinct, and presents several nucleoli of different sizes, giving it in many instances a granular appearance. General remarks.—Having referred to what we have been able to find recorded respecting the genus Gymmnetrus, we found that the figures as well as the descriptions of the external parts were very imperfect, and the anatomy little known; hence we thought it desirable to make the above description fuller than otherwise would have been necessary. Seven or eight species only have been recorded. Cuvier and Valenciennes, in vol. x. p. 365 of their ‘ Histoire Naturelle des Poissons, describe one species from a manuscript in the library of Sir Joseph Banks, which is pro- bably identical with ours, and to which they have given the name of G. Banksti. It was thrown up at Filey Bay, March 18, TAKEN OFF THE COAST OF NORTHUMBERLAND. 301 1796, and taken to York market on the 21st. The description is as follows :—“La queue lui manquait aussi. Sa longueur était de treize pieds, son épaisseur de trois pouces, la longueur de sa téte de sept. Ses flancs étaient garnis de petites protu- bérances argentées disposées en séries longitudinales. La dor- sale, qui s’étendait depuis la téte jusqu’d l’autre extremité, était rouge, et avait deux cent quatre vingt dix et treize rayons (les treize rayons sont sans doute ceux de la nuque) ; la pectorale en avait douze; la ventrale un seul. I] n’y avait point d’anale ; on ne voyait point de dents ; l’intérieure de la bouche était noir ; la distance de anus a la bouche était de quatre pieds. Toutes circonstances qui, comme on voit, se rapprochent beaucoup de ce que nous avons observé dans nos Gymnétres de la Méditerranée.”* This description, though not conclusive, is sufficient to war- rant us in adopting the name given by the French naturalists, and thus to avoid running the risk of adding uselessly to the list of synonymes. Another species is described in the same work, vol. x. p. 298, under the name Gymnetrus Gladius, which very much resembles our specimen ; besides, however, some minor differences, the up- per border of the operculum differs materially—in the former it is convex, and presents three angular points ; in the latter it is smooth and concave.t There are two Norwegian species which appear generally to precede or accompany the shoals of herrings, and hence are called “King of the Herrings.” Of these, the Regalecus Glesne of Ascanius (G'. Ascanii of Shaw) seems to be the most nearly allied to our fish, but it is distinguished from it by the following marks :—It is 10ft. long and 6in. deep ; its length is, therefore, to its depth as 20 tol. From the measurements given in the former part of this paper, it will be seen that our fish is thirteen * It has not been in our power to refer to the work here mentioned ; but to the kindness of Mr. Adam White, of the British Museum, who called our attention to the above record, we are indebted for this extract, and also for another relative to G. Gladius. + The G. Telum of the same authors is also different from our fish, this having 268, that 398 rays in the dorsal fin. 302 ACCOUNT OF A RIBBON FISH times longer than it is deep. This has 268 rays in the dorsal fin ; that 120. Again, the G@. Ascanii is devoid of the transverse dusky streaks on the anterior part of the body so characteristic of our species, but is furnished with longitudinal rows of minute dusky spots, and has, moreover, three broad dusky bands across the posterior part of the body behind the anus, and its forehead is white ; it is also described as having teeth ; the crest also probably differs, if the figure given in the ‘Encyclopédie Méthodique’ be correct ; the dorsal fin is continued round the caudal extremity fora little distance along the ventral line, being somewhat elongated at the extremity, forming a kind of caudal fin. The gill-membrane has only four or five rays. Thus, though there is a striking general resemblance, there are several important points of distinc- tion between the G. Ascanw and the G. Banksit. The other Norwegian species named G. Grillii (Lindroth, Nou- velles Mémoires de Stockholm, xix. pl. 8) is noticed in Griffith’s ‘Cuvier, as being 18ft. long, and having upwards of 400 rays in the dorsal fin, and we conclude, therefore, that it also is distinct from our species.* Of the so-called Indian species, one, the Russellian, described as a probable variety in vol. iv. pt. 2 of Shaw’s ‘ Zoology,’ is only 2ft. Sin. long, and has 320 rays in the dorsal fin, and differs in several other respects. The other is the Blochian Gymnetrus of Shaw, the G. Haw- kenit of Bloch, the figures of which are incorrect. This, how- ever, in all probability ought not to be considered as an Indian species. The history of it, so far as we can gather, is as fol- lows :-— It appears that on the 23rd February, 1788, a species of Gym- netrus was drawn on shore in a net at Newlyn, in Cornwall, and all that is really known of it is obtained from a figure with notes, which was in the possession of the late Mr. Chirgwin, of New- lyn, who freely granted permission to Mr. Couch, of Polperro, to * We have since been informed by Mr. J. E. Gray that G. Grillii has the same number of rays, and the same dark cross bands on the anterior part of the body, as the Cullercoats fish. TAKEN OFF THE COAST OF NORTHUMBERLAND. 303 have a copy taken of it. Through the kindness of Mr. Couch, we have been favoured with a reduced copy of the above figure, made by Mr. Thomas Q. Couch ; and in the letter accompanying the drawing, Mr. Couch states that Mr. Chirgwin assured him that his figure was the only true original, the fish having been drawn ashore not far from his house ; that, however they might differ, all other figures were copied from his, and that the note written on his figure is the only one originally made from the specimen. Mr. Couch further says, that he has no doubt, from circumstantial evidence, that the figure and account of the G. Hawkenii were communicated to Bloch, by a Mr. John Hawkins, brother of the late Sir Christopher Hawkins, Bart. Mr. Haw- kins himself, as Mr. Couch concludes from Mr. Chirgwin’s re- marks, did not actually inspect the fish. The copier of the figure sent to Bloch, appears to Mr. Couch to have committed a great mistake by attempting to correct one which he supposed to have been made by the original draftsman, and the mistake consists principally in his having removed the two filaments in front of the dorsal fin to the situation of the ventral fin, thus making four filaments there instead of two. The same mistake appears to have been made with regard to the figure of the G. Hawkenis in Yarrell’s ‘ Fishes, that figure being, as Mr. Yarrell informs our friend Mr, Alder, incorrect as regards the number of ventral filaments, and the addition of the caudal fin. It appears therefore that the G. Hawkenii of Bloch, is simply the fish caught at Newlyn incorrectly copied. In the notes ap- pended to the drawing sent us by Mr. Couch, and whieh are copied from the original, are merely mentioned the date of the capture as above and the measurements ; “ its length without the tail, which it wanted, was 83 ft., its extreme breadth 103 in., and its thickness but 23in. Tts proportions therefore, allowing the tail to be somewhat deficient, come pretty near to those of our fish ; if the drawing however, is to be relied on, it differs from ours in having only two filaments from the head with expanded feather-like extremities, and. in having the ventral processes like those of the head. The fins also are crimson, and the body is marked all over by delicate 304 ACCOUNT OF A RIBBON FISH roundish spots, and has a few obscure streaks obliquely placed below the lateral line. On the whole, then, we are inclined to believe the Cornish spe- cimen distinct from the G. Banksii, though, from the evident want of knowledge of the draftsman, much reliance cannot be placed on his details. Notwithstanding the rarity of the genus Gymnetrus, there is every reason to believe that specimens of it have been taken from time to time off the north-eastern coast of England. It appears by the ‘Annual Register, that a fish was captured off Whitby, January 22, 1759, closely related to, if not identical with, our species. The account, which may be interesting, we here re- produce. It is by Lionel Charlton, author of a ‘History of Whitby’ :-— “Yesterday (Jan. 22) a very extraordinary fish was brought here by our fishermen, which broke into three pieces as they were hauling it into the coble. It was 11 ft. 4 in. long, exclusive of the tail, had a head like a turbot or brat, was about a foot broad near its head, but not above 4 or 5 in. near the tail, and not anywhere more than 3in. thick. The thickest part was its belly, and it gradually diminished away towards the back, which was sharp, and had all along it one continued fin from the head to the tail. It was covered with an infinite number of white scales, which stuck to and dyed every thing that it touched ; and might be said in some sort to resemble the quicksilvered back of a look- ing-glass. It appeared, when laid on the sand, like a long oak plank, and was such a fish as nobody here ever saw before, which caused a vast concourse of people round it the whole day.” The breaking of the fish was owing to its great delicacy of structure, and probably its little capacity for lateral motion. It was necessary to take great care in removing the Cullercoats fish for fear of fracture from the same causes. We are informed by Mr. Stanton, of Newcastle, that upwards of fifty years ago a silvery fish, resembling in its general charac- ters the subject of this paper, was exhibited here, and we have been favoured by Mr. Robert Bewick with a copy of a hand-bill relating to a fish shown in this town March 27, 1794, undoubt- TAKEN OFF THE COAST OF NORTHUMBERLAND. 305 edly referring to the specimen seen by Mr. Stanton. It is as follows :—“ To be seen at Moses Hopper’s, Flesh Market, a most curious fish, taken at Newbiggen by the Sea, 10 ft. long, 1 ft. bread, 2 in. thick, and is thought to be the greatest curiosity that was ever seen in the kingdom before.” This fish was sketched by our celebrated townsman Thomas Bewick, but unfortunately the sketch has been mislaid. We have lately been favoured with a letter from Mr. George Tate, of Alnwick, respecting a fish of this genus, from which we make the following extract :—“ A fish was exhibited in January or February of the year 1845, similar in its general form to that a drawing of which you showed me when I was last in New- castle. One of the Preventive Service men observed this fish lying in a shallow pool in the sands, about a mile south of Alnmouth, where it had been left by the receding tide. Its great length and unusual appearance at once raised the man’s curiosity and excited his fears. On approaching it the creature bent itself round so as to appear like the rim of a coach-wheel, and the man supposing it was about to dart upon him, drew his sword and struck it on the head. The fish struggled much, but the man striking it repeatedly, at length succeeded in cutting off its head. “ This fish was 16 ft. long, 11 in. deep, and about 6 in. thick at the thickest part, from which it very gradually diminished both in thickness and depth. The eye was large, measuring about din. in circumference. The teeth very small and very acute. The skin was smooth, and no pustulations or hard points were observed, neither were any transverse streaks noticed ; but there were a few longitudinal ridges or corrugations about half an inch apart along the sides. The colour was a silvery gray, and the skin was covered by minute silvery-looking scales or particles, which were in such great quantity, that in the course of the struggles the creature made after being struck, the spot where it was found was covered over with them. There were no pectoral or ventral or anal or caudal fins, neither was any crest observed. These however may have been broken off, as the head was much injured by the blows which it had received. One fin, of a rich dark crimson colour, extended uninterruptedly from the VOL. I. 88 306 ACCOUNT OF A RIBBON FISH neck along the back to within a few inches of the tail, which ended in an obtuse point. The fish was very beautiful ; the large eye, the rich crimson-rayed fin cresting its back, and the bright silvery hue of its body, rendered it a striking and attrac- tive object.” The fish thus described by Mr. Tate, it will be seen, resembles rather the Regalecus Gilesne, in its having teeth and being devoid of the transverse streaks. The following account of the capture of two fish of this genus has been taken down by us from the oral relation given by John Blackett Anderson, of Walker, near Newcastle. He states he re- collects the taking of two fish about fifty years ago at the outer Fern Islands. They were left by the tide in a shallow pool, and a signal being made by the keeper of the lighthouse, a boat went from the shore and brought them to Bambrough. They were sick when taken. One was about 4 ft. longer than the other, the larger specimen was 18 ft. long. It could not be less, for it was as long as the breadth of a house-end which measured 18 ft. and against which it was laid out on a bench. The fish were about a foot deep, and were flat ; their colour was silvery, like a silver fish, but not so white. There were four processes, about 18in. long, from the head, of a red colour, like the feelers of boiled lobsters ; they tapered gradually towards their ends, which were enlarged to the form and size ofa large button. Thinks these specimens occurred in spring. They were kept till putrid, and then thrown away. They excited much interest throughout the neighbourhood. Recollects them well, for he was living then on the spot. Has not seen the Cullercoats fish. We have moreover learnt, from a Norwegian captain who fre- quents this port, and has traded to Archangel, that in the White Sea, fish closely resembling the Cullercoats one are occasionally seen ; the silvery colour, long attenuated form, and rapid undu- lating motion, being their chief characteristics. They are there called Stone Serpents. It has occurred at once to many here, and to ourselves also, on first viewing this Gymmnetrus, that it may possibly have been taken for the famous Sea Serpent. The Archangel name of the fish, seen there, strengthens the idea that it may at times ' 2ve 9 TAKEN OFF THE COAST OF NORTHUMBERLAND. 307 deceived the eye of some credulous mariner, from its rapid un- lating motion, linear form, and from its occasionally eppearing at the surface, and leaving a lengthened wake behind it, thus creating an exaggerated idea of its extent. On consulting, however, the accounts which have appeared of the Sea Serpent, we find that they relate in most instances to creatures widely different from the Ribbon Fish, such as whales, seals, sharks, &c., seen under disadvantageous circumstances or imperfectly observed. Still, though the Gymnetrus may not have originated the idea of the existence of a marine serpent, we think it not improbable that the occasional appearance of this fish may very materially have tended to keep up among the Nor- wegian fishermen that faith which they are stated to hold in the existence of such a monster. Of the habits of the Gymnetrus little can be said. The deli- cate general conformation of the body, the smallness and tender- ness of the mouth, the absence of teeth, the delicacy of the fins, show clearly that it is a fish not organized for attack—the dorsal crest and the ventral processes being obviously for the purpose of balancing the body, and not for either attack or defence. Its means of defence may consist partly in the bone-studded skin, but chiefly in the adaptation for flight, evidenced in the com- pressed form of the body, and in the great length and power of the tail. The small amount of half-digested food found in the stomachal cecum goes so far to prove the non-rapacious habits of the Gymnetrus, and make it probable that its habitual food is confined to the spawn of other fish, and the soft, small, and defenceless inhabitants of the deep. The absence of air-bladder seems to indicate the sea-bottom as the natural resort of this fish, where its food would be most abundant. The only evidence of its being indigenous on the north-eastern coast rests in its having been observed six times since 1759. There is little doubt of the remarkable circumstance that all the six have been captured during the spring months. In conclusion, we have only to state, that the fish is now in the possession of Mr. Edward Whitfield, of Newcastle, who kindly granted us permission to make the necessary examinations, and 308 ACCOUNT OF A RIBBON FISH we are happy in being able to state that that gentleman has ex- pressed his intention of presenting this rare fish to the museum of the Natural History Society of Northumberland, Durham, and Neweastle upon Tyne. Since writing the above we have received a pamphlet entitled “An Account of the Rare Fish, Regalecus Glesne, caught off Cul- lercoats,” &c. In it we find a copy of a figure of a Gymnetrus taken at Newlyn, in Cornwall, on Saturday, 23rd day of February, 1788. This figure, with descriptive notes appended, is bound up at the end ofa copy of Pennant’s ‘ British Zoology’ in the Banks- ian Library. Mr. J. E. Gray supposes this figure and notes to be the authority for the various descriptions and figures of the Cornish specimen of G. Hawkenit. The Banksian figure, though possessing a good general resemblance to a Gymmnetrus, differs so widely from the figure we have been favoured with by Mr. Couch, that we believe neither of them to have been a copy of the other, and the differences in the measurements that accompany the figures are such as to strengthen this belief; the length of the Banksian specimen is said to be 8 ft. 10in., Mr. Couch’s 83 ft. The depth of the former is 10 in,, of the latter 103 in. ; the thickness of the former 24 in., of the latter 2?in. These dis- crepancies could scarcely have arisen from errors of copying, but are more likely to be the result of examinations by different ob- servers. It would therefore appear that there must either have been more than one fish caught on the Cornish coast, or else that different drawings and descriptions have been made of the same specimen. The figure in the pamphlet does not appear to us materially to elucidate the species of the Cornish fish ; indeed the details both of the figures and descriptions are so imperfect that they may quite as readily be taken for the G. Gladius as for the G. Banskii ; the spotting of Mr. Chirgwin’s drawing brings strongly to mind the markings of the G. Gladius. We are glad to be able, from a letter of Mr. Yarrell in the above pamphlet, to add to the list of specimens now put on record one which was cast on shore alive at the village of Crovie, near TAKEN OFF THE COAST OF NORTHUMBERAND. 309 Macduff, after a severe north-easterly gale in March, 1844. It is thus described :—“ Length without the tail, which was wanting, 12 ft., greatest depth 12 in., greatest thickness 2? in. The dor- sal fin was 24 in. in height, and extended from the back of the head to a point near the tail. Rays in the dorsal fin, apart from its anterior elongation on the head, 264. Filaments rising from the head, 15 ; the longest measuring 27 inches. They were con- nected at the base by a thin membrane, similar in consistency to that which connects the rays of the dorsal fin, and are evidently a continuation of that fin. The pectoral fin is 25 in. long, the rays 12in. The ventrals consisted of two filaments 3 ft. in length. They were fringed with a thin membrane on two sides, and had evidently been broken. The head was 9 in. long from the point of the lower jaw to the end of the operculum. The whole body was covered with a delicate silvery white membrane, under which appeared a series of tuberculated and smooth bands, extending over the whole length of the body ; twelve of these bands occu- pied the space above the lateral line. When the fish was in a fresh state these bands did not appear distinctly, but when the skin was taken off they appeared distinct enough. Behind the pectoral fins appeared a few narrow dark bands extending across the fish ; these were quite distinct when the fish was in a fresh state, but the skin does not retain a trace of them. ‘The dorsal fin had an orange tinge, and the lateral line extended along the lower third of the body. The distance of the vent from the end of the operculum was 46 inches.” We agree at once with Mr. Yarrell in pronouncing this to be the same species as the Cullercoats fish, and it is confirmatory of our opinion that the crest was really a continuation of the dorsal fin. This Scotch specimen, like the English ones, was caught in the spring, and makes the eighth British example of this fish, which is therefore not so extremely rare as has been supposed. We observe that in the last Number of the “Annals,” Pro- fessor J. Reid, of St. Andrews, has given a highly interesting des- cription of what he believes to be the first British example of the Deal fish, and we take the present opportunity of stating that in the Newcastle Museum there is a specimen which was taken at Newbiggen, on the Northumberland coast, June 18th, 1844. 310 ACCOUNT OF A RIBBON FISH. This specimen is dft. 5in. long, and has Ift. maximum depth. The body was of a silvery gray, and the dorsal fin and tail red. Another example of the occurrence of the Deal Fish is given by Mr. Charles St. John, in his Field Notes and Tour in Suther- landshire. The following description is quoted from that work :—“ Length, 3 ft. 6 in. ; depth, 7 in. ; greatest thickness, between half and three-quarters of an inch ; colour, bright silver, with one very thin crimson fin running the whole length of the back. The tail very transparent, fan-shaped, and of a bright crimson. A large flat eye and a small mouth, which the fish had a peculiar power of elongating to a considerable extent.” We have seen a very good coloured drawing of this individual by Mr. St. John, and understand that it was taken alive, hooked through the back by a common haddock hook.

GentLEMEN,—At the conclusion of my year of office, and before resigning the chair to which you did me the honour of electing me at the last anniversary, it now becomes my duty to take a short review of the proceedings of the Club during the past season. In doing this, it is not my intention to enlarge upon the advantages of the study for the advancement of which we are associated,—a subject on which I hope we are all agreed,—but rather to confine my remarks as much as possible to matters of a practical nature. Our meetings during the year have not, perhaps, left us any- thing veryremarkable to record, but, at the same time, they may be looked back upon with satisfaction, as having afforded us many opportunities of instructive intercourse and enjoyment, while rambling together over those pleasant tracts of country in which they have been held. But although, excepting in one instance, no great novelty has been met with during our excursions, yet I hope to show that the year has not passed over without some results, due to the exertions of individual members, which, em- bodied in the Transactions of the Club, will afford a permanent memorial of its usefulness. In no country in Europe has so much been done for the ad- vancement of local natural history as in Great Britain. Our works on native species are more numerous and accurate, especially in the zoological department, than those of our conti- nental neighbours, while the great extent of our sea coasts gives a variety to our natural productions which few other countries VOL. I. Tt 312 PRESIDENT’S ADDRESS. can boast of. If, however, Great Britain stands pre-eminent in this respect, I think I may say with safety that there is no part of it in which the native productions have been more successfully studied than in the district where we reside. A Flora of Nor- thumberland and Durham by Mr. Winch, a Catalogue of the Birds of Northumberland by Mr. Selby, and of the Zoophytes by Dr. Johnston, together with many excellent papers on local Geology, were published in the Transactions of the Natural History Society. These, with the Catalogue of Coleopterous In- sects by Messrs. Hardy and Bold, that of Mollusca by myself, and of Permian Fossils by Mr. Howse, in the Transactions of this Club, contain a large mass of information on our local natural history: and, if we also take into account what has been done by our neighbours of the Berwickshire club, there cannot, I think, be a doubt that the indigenous Fauna and Flora have been more fully investigated in this district than in any other portion of the united kingdom. Nevertheless much still remains to be done. The Fishes, the Crustacea, the Echinodermata, and many of the lower tribes of marine animals remain yet to be investigated ; and, as nearly twenty years have elapsed since the papers in the Natural History Society’s Transactions were written, much ad- ditional information can now be given on the subjects of which they treat. It was therefore very properly determined by the Club to publish a complete Fauna and Flora of the two counties, of an uniform size and in an unexpensive form. The materials are ample and we have among us naturalists fully competent to the task. The chief difficulty is in the expense. We have al- ready, unfortunately exceeded our means in that respect, but I hope some plan may be adopted to lighten our present responsi- bilities, and that with careful management, aided by the experi- ence we have now acquired, we may be enabled to proceed in the publication of our Catalogues, so that some portion at least may appear during each year. The limited sale which works of a merely local and scientific character can command, has been found a great impediment to the carrying out of our plans. In the hope of removing this in part, and under the impression that many gentlemen of the two counties might, if the subject were PRESIDENTS ADDRESS. 313 named to them, be glad to place these local records in their libraries, an appeal to them was determined upon at the last anni- versary, which, I am sorry to say, has not been attended with the success anticipated. It is gratifying, however, to know that the number of our members is still gradually increasing, and that it now amounts to one hundred and eleven. Before quitting this subject, | may be allowed to recommend to those members intrusted with the preparation of Catalogues, to make out at once manuscript lists of those species they have met with in each department, to be added to as opportunity offers, thus forming a frame-work which will greatly facilitate their future operations. All the members of the club may, indeed, occas- sionally contribute something towards this object, if they will com- municate anything rare or curious they may meet with to the gentlemen preparing lists, or, what would keep up the general interest more effectually, bring the specimens to our meetings for exhibition. It may not be amiss also to remind you of a rule of our club, by which itis enjoined that each of the members should assist in forming a local collection to be placed in the Newcastle Museum, by which the species published in the catalogues may be identified, and the study of our local natural history further en- couraged. By this means, too, scientific strangers might be able to see at a glance the natural productions that our counties afford. It is to be hoped that the Natural History Society may ere loug be able to appropriate a particular part of the Museum for the purpose, which would greatly assist in carrying out the project. That society has now purchased the extensive herbarium of the late Mr. Robertson, one of the most distinguished of our botanists, which, when properly arranged for reference, will afford great assistance in the study of our native plants. The additions to our Fauna during the year have been con- siderable. Dr. Embleton has lately procured from Stockton specimens of the black rat, a native species now nearly extinct in this part of the country. Some rare birds have also been noticed. One of the rarest as well as the most beautiful of these is the Bohemian Waxwing (Bombycilla garrulus) whose visits to this country have hitherto been few and far-between, This 314 PRESIDENTS ADDRESS. winter, however, it has made its appearance in considerable numbers, driven probably from its usual continental haunts by the severity of the season. Several individuals have been shot on the banks of the Tyne, as well as in some other places in this neighbourhood. Some birds not generally considered migratory have likewise appeared in more than usual numbers this winter : —of these may be mentioned the greater spotted Woodpecker and the Kingfisher. Mr. John Hancock shot two specimens of the Pigmy Curlew (Z'ringa sabarquata) out of a flock on Whitley Sands in September last. Tengmalm’s Owl (Sirix Tengmalmi J, another rare visitant, has also been met with: one occurred on the coast north of Whitburn, and a second individual was shot near Rothbury in April last. These specimens, which are male and female, are now in the possession of Mr. John Hancock. A young male bird of the Goshawk (Accipiter palumbarius) was shot in Northumberland this year. The red Viper has been added to the Northumberland Fauna by Mr. F. H. Salvin, who cap- tured a specimen on Cheviot in October last. The specific difference between this, which is supposed to be the Coluber chersea of Linneus, and the common viper has not been satisfactorily made out. Another specimen of that remarkable fish, the Gymnetrus Banksti, the account of which forms so conspicuous an ornament of our last year’s Transactions, has lately occurred at Redcar, a place so nearly within the limits of our district that it may not inappropriately be mentioned here. It was alive when caught, and measured 11 feet in length, somewhat less than the indivi- dual got at Cullercoats, which in colour and markings it appears to have closely resembled. It has been purchased for the British Museum. A less conspicuous, though scarcely less rare British fish, the Centrolophus pompilius, or Black Fish, was caught last autumn at Cullercoats, and, happening to be there at the time, I fortunately secured it for our Museum. The only British locality hitherto recorded for this fish is the coast of Cornwall, on which a few individuals have been obtained at rare intervals, amounting, I believe, to no more than five since its first discovery in the time of Borlaise, nearly 2 century ago. Its occurrence on this coast, PRESIDENT’S ADDRESS. 315 so far beyond its supposed geographical range, is therefore inter- esting. One of those strange looking inhabitants of the ocean the short Sun Fish (Orthagoriscus Mola) was caught at Cullercoats last summer and brought up to Newcastle for exhibition by the fishermen. It fortunately afterwards came into the hands of Dr. Embleton for dissection, as did also a fine specimen of the Por- beagle Shark (Lamna Cornubica) above eight feet long, caught at Hauxley. ‘Two or three examples of this shark have occurred on the Northumberland coast in the course of the autumn. Among the Mollusca, the following rare species have been added to our Fauna during the year. Bulla strigella, Rissoa vitrea, Pleu- rotoma nebula, and Pleurotoma brachystoma ; also an undescribed species of Odostomia, which I have named Odostomia conspicua. These were all dredged off Whitburn. The employment of the dredge on our coast, now for the first time successfully, leads to the hope that many important additions to our Fauna may be made in future years by this means ; as the dredge has now become an essential auxiliary to the naturalist in exploring the wonders of the deep. An Ascidian new to the coast, Cynthia echinata, occurred to me when at Whitburn in the summer, and I was so fortunate as to meet with an undescribed species of the same family at Culler-. coats in October last, which I have named Molgula siphonata. Mr. Bold informs me that the last year has not been a favour- able one for the labours of the entomologist. Owing perhaps to the unwonted dryness and ungenial temperature of the early months, the common Lepidoptera did not appear in any thing like their usual numbers, and during the early summer, those pests of the garden, the common white butterflies, were scarcely to be seen. Towards autumn Mr. Bold noticed them rather more frequently, and saw several patches of cabbages rendered useless by hosts of the larvae of Wamestra Brassice. The same or a nearly allied larva was in abundance on the halm of pease. Coleoptera were certainly not in their usual quantity. Never- theless Mr. Bold secured several new to our Fauna, and again took Colymbetes dispar, described in the last part of the Club Transactions. 316 PRESIDENT’s ADDRESS. A curious little crab, Zurynome aspera, dredged by Mr. R. Howse, off Whitburn is new to the coast, as is another small and rather rare species, Hbalia Cranchit, got at the same time. But the most interesting discovery in this department is that of a burrowing Cirripede found at Cullercoats by Mr. Albany Hancock. ‘This little creature forms a habitation by boring into the substance of dead univalve shells, a habit until lately unobserved in this tribe. The anatomy, too, of this animal is curious, from its shewing a great deviation from the usual form of the class, and an approach to the typical crustaceans. This species, for which a new order and genus have had to be formed, is called by Mr. Hancock, Alcyppe lampas. The only Echinoderm met with new to the coast is the Syrin Harveyt, got by Mr. Howse in one of the dredging expeditions off Whitburn already mentioned. This species was first described in Forbes’s ‘British Starfishes’ from specimens found at Teign- mouth in Devonshire, the only habitat then known, and I am not aware of its having been since met with until the present time. In Zoophytes I have again the pleasure of alluding to the dis- coveries of Mr. Albany Hancock. On the excursion to the Northumberland lakes, two beautiful fresh-water zoophytes of the order Bryozoa,—a Fredericella and a Paludicella,—were got in Crag Lough by that gentleman. This success induced him to pay two more visits to the same locality, during which in that and Bromley Loughs, two additional species were found, belonging to another genus, Plumatella, as well as a specimen or two of what appeared to be a third Plwmatel/a, and an imperfect specimen of an Alcyonella. With the exception of a Pluma- tella found by Mr. Hogg ina rivulet near Stockton, and Alcyonella stagnorum got by Mr. Embleton in a pond at Howick, none of the freshwater Bryozoahad been previously observed in these counties. Thegenus Paludicella is new to England. Mr. Hancock considers ihree of the species undescribed, which he has named Plumatella punctata, Plumatella Allmani, and Paludicella procumbens. The other species found were Lredericella sultana and Alcyonella stagnorum. Along with these novelties, a beautiful little flesh- coloured Hydra, probably a variety of Hydra fusca, was found in PRESIDENT’S ADDRESS. 317 considerable abundance. In his microscopical investigation of this species Mr. Hancock has succeeded in making out, more completely than has been hitherto done, some important points in the anatomy and development of this curious genus, the first account of whose habits and properties, when given by Trembly, appeared to the world like a romance. Mr. Hancock’s investi- gations have been principally directed to its second or oviparous mode of reproduction, the process of which he has satisfactorily ascertained. He has been equally successful in making out the character and mode of operation of the stinging apparatus with which this little animal is supplied. This consists of minute bodies embedded in the tentacles having a poison bag surmounted by a tribarbed dart, which is capable of being ejected upon its prey. To complete the list in the zoological department, I may men- tion that three species of polype-like animalcules, apparently new, and uniting the Jnfusoria with the Campanularian zoophytes more nearly than any yet known, were met with by myself during the summer ; two of them, marine, on the shore at Whitburn, and one from the freshwater of Crag Lake. In Botany little novelty has turned up. The only plants new to the counties are Ulex nanus, discovered by Mr. Daniel Oliver, junior, near Staward Peel, and Myriophyllum alterniflorum, lately found in Crag Lough by Mr. John Thompson. Potamogeton rufescens, gathered by Mr. Storey in the same lake, may probably be also considered new to our Flora. Some additional habitats for the rarer plants will be found in the account of the field meetings. Mr. Tate’s researches on the polished and scratched surfaces of rocks, viewed in connection with the boulder formation, shew that geology has not been entirely neglected, The indications of im- portant changes in our planet afforded by these surface deposits, and the marks of violent action they have left, involve some of the most curious problems in geology. They have until now been little studied in our neighbourhood, but the communication read at our last meeting, and ashort paper on a similar subject in the 318 PRESIDENTS ADDRESS. 4th Part of our Transactions by Mr. Loftus,* shew that a rich field is still open for research even in the common deposits of stones and mud, with which the surface of these counties is everywhere covered. It remains now to give a brief account of the meetings held during the year ; in drawing up which I have occasionally availed myself of the assistance afforded by the notes of our secretary Mr. Storey. The first field meeting took place on the 18th of May on the banks of the Wansbeck above Morpeth. The weather at the time of starting, and indeed during the day, being somewhat unfavourable but few of the members attended. They assembled at Morpeth station and strolled by the side of the Wansbeck as far as Mitford, and after a pleasant ramble of several hours, in which a few plants were collected, including Arabis hirsuta, Myrrhis odorata, Arabis thaliana, and several ferns, they returned towards Mor- peth. Two of the members, Mr. Storey and Mr. Burnet, in- tending to search for Lguwisetum umbrosum, had proceeded by an early train several miles to the northward of Morpeth. The Equisetum referred to appears to have been first noticed in Nor- thumberland, (only the second recorded English locality,) by Mr. Joseph Sidebotham, who announced this interesting discovery in the Phytologist for 1848. After walking three or four miles, they had the good fortune to collect several specimens of this rare plant on the banks of the Coquet near Felton ; but as the season was somewhat advanced only two fertile stems were procured. By the * Tt may be as well to notice here a small mistake in Mr. Loftus’s paper, where he states that a block of porphyry observed by myself on the Lanchester road near Sunnyside was similar to what is now found in the Cumberland mountains. The boulder which I observed, nearly twenty years ago, was of Cheviot porphyry, and consequently leads to a difterent inference as to the direction of the current that brought it there. I mentioned to Mr. Loftus my having observed at the same time among the water-worn stones taken from the neighbouring fields and broken up to mend the roads, more than one example of the Cumberland rocks, especially of the epidotic porphyry of which the celebrated boulder stone of Borrowdale is composed. This may have led to the mistake. PRESIDENT’S ADDRESS. 319 side of the same stream Hquisetum hyemale and LH. palustre were likewise observed. These gentlemen afterwards joined the party at dinner at Morpeth. The second meeting was at Dipton and Devil’s water on the 8th of June. On this occasion there was a better attendance of mem- bers. Starting from the Hexham station, the party proceeded to Dipton, or Deepdene, as I believe it was originally called: from thence two or three of the members extended their walk by Dot- land Park to Dukesfield, in search of Lysimachia vulgaris, which had lately been observed to grow in that place. They fortunately succeeded in obtaining the object of their search. The rest of the party spent the morning very agreeably in following the down- ward course of Dipton burn, through a romantic valley, varied with bold rocks and overhanging woods. Some rare plants were collected, particularly Veottia Nidus-avis and Melica nutans. A few of the members, who had left Neweastle by a later train, joined the others near Newbiggin, the seat of John Atkinson, Ksq., beautifully situated near the junction of Dipton burn with the Devil’s water. Those of the party who called at the house were hospitably entertained by Mr. Atkinson at lunch. They then proceeded up the-Devil’s water to Nunsbrough, a picturesque spot, where the stream winds very circuituously through a prettily wooded area surrounded by elevated banks so as to form a kind of amphitheatre. Crossing the stream at this place, where many of the stragglers of the party had united, they turned downwards by the Devil’s water towards Dilston, but the approach of the dinner hour, which after a long days ramble had considerable attractions, especially to those who had not partaken of Mr. At- kinson’s lunch, made it necessary to pass the ruins of the ancient seat of the Ratcliffes with only a hasty glance. Seventeen sat down to dinner at the Railway Inn, near Corbridge Station. After dinner, notice of the discovery of a boring Cirripede, at Cullercoats, by Mr. Albany Hancock, was read by the chairman ; and a letter from the senior secretary, Mr. John Thornhill, who had taken an active part in the organization of the club, an-~ nounced his intention of resigning in consequence of his inability from want of sufficient leisure to attend to the duties of the VOL. I. . vu 320 PRESIDENT’S ADDRESS. secretaryship. Four new members were elected :—Dr. De Mey of Newcastle; Mr. Jefferson, Surgeon, Hexham; Mr. Herbert Crawshay, and Mr. Edmund Crawshay of Gateshead. The day though not bright was, upon the whole, tolerably favourable, and most of the party appeared highly pleased with the excursion. Several good plants were collected, but, excepting those already mentioned, perhaps none are particularly worthy of record. The country travelled over is rich in the beautiful tribe of Orchidaces ; eight different species of which were gathered during the day. The third meeting took place on the 22nd of June. The tract of country selected for the excursion included Hawthorn and Horden Denes ; but in consequence of the distance of these denes from the nearest railway station and from each other, it was found impossible to include them within the limits of a day’s excursion. Hordon dene was therefore the only one visited. The usual magnesian limestone plants were gathered, including some of the rarer of the Orchis tribe ; Hpipactis ensifolia was got in fine flower, and the Fly Orchis, Ophrys muscifera, was also obtained. The beautiful Primula farinosa was found growing in such profusion in one spot near Hasington, as to colour the ground with its lilac flowers. A few of the members visited the old hall at Horden to examine the ancient staircase and other antiquities of the interior. After a long day’s ramble the party eventually dined together at the Bridge Inn, Bishopwearmouth. The fourth meeting was at the Northumberland lakes on the 20th of July. Bardon Mill was the place of rendezvous, and the muster was tolerably good, notwithstanding the rather unpromi- sing appearance of the morning. ‘The day, however, proved fine, with the exception of a few slight showers. The party, two or three of whom breakfasted at the village inn, pursued the devious footing of a rustic track through the valley of Bardon Burn to Chesterholme. The wooded sides of the valley afforded one or two good plants to the botanists, the most attractive of which was the pretty Pyrola minor. Crepis succisefolia and Orobanche major were likewise gathered. At Chesterholme the numerous well- preserved antiquities obtained from the neighbouring station attracted much attention. After exploring the remains of the PRESIDENT’S ADDRESS. 321 Roman station of Vindolana, the party crossed the country to the old military road, in the vicinity of which are the little moorland lakes, or loughs, as they are provincially called, that were to form the boundary of the day’s excursion. These Loughs, situated in a wild district unadorned with wood, possess little picturesque, beauty, with the exception of Crag Lough, a small sheet of water lying beneath fine basaltic cliffs, formed by the whin-sill, which here rises into a range of hills crossing the country in a direction nearly east and west, and presenting a bold escarpment to the north. These hills give a striking character to the surrounding scene, and are well known to the antiquary from the circum- stance of the celebrated Roman wall passing along their summits. A few of the members explored the northern shore of Crag Lough, where Mr. Storey gathered Polamogeton rufescens, P. perfoliatus and P. pectinatus: the remainder pursued the line of the Roman wall over the top of the crags, descending to the lake at the east end, where some of the more assiduous naturalists commenced turning over the loose stones at the water’s edge. This search was rewarded by the discovery of two beautiful fresh-water zoophytes, new to the north of England, which, as before recorded, were obtained by Mr. Albany Hancock. A few freshwater shells were observed, among which were Physa fontinalis, Planorbis albus, and Ancylus lacustris ; these were all of small size, ap- parently dwarfed by their exposure in this elevated situation, A searce little bivalve, Pisidium nitidum, was.also found. Brom- ley Lough was only reached by two of the botanists, Mr. Storey, and Mr. Daniel Oliver, intent upon obtaining ‘the glory of this barren waste’, the beautiful white water lily, Vymphca alba, which here grows truly wild. Scutellaria galericulata was likewise found, growing upon the margin of this lake. Again following the line of the Roman wall, whose preservation in so perfect a state called forth the admiration of those gentlemen who had not previously seen it in this locality, the party passed along the cliffs as far as the great Roman station of Housesteads, the ancient Borcovicus, where some time was spent in examining the extensive remains. From hence the party, well pleased with the events of the day, made the best of their way to Haydon 322 PRESIDENTS ADDRESS. Bridge, where an excellent dinner was provided at the Anchor Inn. This was rather hastily dispatched to save the evening train to Newcastle. On occasion of the fifth meeting, the club again turned their steps westward, selecting a tract of country a little beyond that of the previous meeting. In consequence of the unsettled state of the weather the attendance was thin. The members assembled at Haltwhistle station ; whence the walk led to Wall Town Crags, a favourite locality of the botanist on account of the rare plants that here grow on the basaltic rocks. The plants of this locality, which had been visited by the club on a former occasion, are so well known that it is unnecessary here to enumerate them. The remainder of the day was spent in traversing the wild and un- dulating country towards Gilsland. During this walk and on the banks of the Irthing the following plants were obtained. Saxifraga aizoides, Galium boreale, Hieracium boreale, H.umbella- tum, Vicia sylvatica, Potamogeton gramineus, P. pusillus, and As- plenium viride. A heavy storm of rain, accompanied with thun- der and lightning, came on in the afternoon and dispersed the party, some of whom got very much wet. Only six members, in- eluding three who had gone to Gilsland by a later train, assembled at Greenhead to dinner. The secretary announced a paper on the freshwater polypes got at the previous meeting by Mr. Albany Hancock, but want of time prevented its being read. The last field meeting of the season,—an extra one,—took place on the 7th of September, at Ryhope. Again an unfayour- able state of the weather prevented a large assemblage. The members from Newcastle were joined at Sunderland by a few of those residing in that town. The walk chosen led over Tunstall Hill, commanding one of the most extensive prospects in the neighbourhood. The view of Sunderland and the surrounding country, with a wide expanse of sea beyond, was very fine. Some good fossils are obtained on this hill, but on the present occasion, time did not allow of a search being made for them. Thence the route lay through Tunstal Hope to Ryhope. After resting a while at this village, the party proceeded to Ryhope Dene, and passed through this romantic little valley to the sea coast. Here PRESIDENT’S ADDRESS. 320 they divided: some going forward by the sands to Seaham Har- bour, while two or three, less disposed for walking, remained to explore the rocks at low tide. The shore on this part did not afford much worthy of notice, but an elegant and delicate little zoophyte of the genus Plumularia was found clothing the under side of shelving rocks near low-water mark. It proved to be a curious variety of P. pinnata with the ova-vesicles attached to the creeping root-fibres, which had not before been observed on this coast, where the species is usually found in deep water. Dr. Johnston informs me that he has‘received the same variety from Devonshire. Mr. John Storey, jun., one of the party who had remained behind, took some beautiful sketches of the coast scenery, which is here rendered picturesque by the varied forms assumed by the magnesian limestone rocks. A few land shells were collected in Ryhope Dene, but owing to the lateness of the season few plants were observed. Scolopendrium vulgare grows to a large size in this dene. A frond of one of the specimens collec- ted measured from the base to the apex, after being dried, above 19} inches. The party united again at Ryhope and returned by railway to Sunderland, where they examined the extensive ex- cavations of the magnesian limestone for the docks now in progress, and afterwards dined together in Bishopwearmouth. An evening meeting for the reading of papers was held in the Rooms of the Natural History Society in Newcastle, on the 12th of December. A considerable number of members and their friends, including some ladies, assembled in the Museum, which was bril- liantly lighted with gas. Numerous beautifully dried and moun- ted specimens of flowering plants, collected at the field meetings by Mr. Daniel Oliver, jun., were displayed on the tables ; as were also a series of forty exquisite prints in chromo-lithography, being the proof plates of a work about to be published on the Cephalo- poda, or Cuttle Fishes, of the Mediterranean, by M. Verany of Genoa: accompanying these, specimens of the animals in spirits were exhibited, particularly that of the Argonauta Argo, or Paper Nautilus, about which there has been so much controversy among naturalists. Many illustrated works on Natural History, belonging to the Literary and Philosophical Society, were also 324 PRESIDENT’S ADDRESS. laid on the tables. The company having adjourned to the com- mittee room, two short papers,—‘ Additions to the Mollusca of Northumberland and Durham’, and an ‘Account of three new species of Animalcules,—were read by the president, the former illustrated by specimens. The next paper was by Mr. Carr of Dunstan Hill, ‘On the composite names of places, of Anglo-saxon derivation, chiefly in Northumberland.’ In the unavoidable ab- sence of Mr. Carr, this interesting paper was read by the secretary Mr. Storey. Mr. Tate of Alnwick followed with a paper ‘On polished and scratched Rocks, viewed in connection with the Northumbrian boulder Formation,’ which was listened to with great attention. ‘Notes on a species of Hydra found in the Northumberland lakes, and extracts of an elaborate paper (which time would not allow of being read entire) ‘On the Anatomy of the Fresh-water Bryozoa, with descriptions of three new species,’ by Mr. Albany Hancock, were read by the secretary. Mr. Wailes, in conclusion, called the attention of the meeting to the splendid coloured plates of Bateman’s ‘Orchidacee of Mexico and Guata- mala,’ a copy of which he had kindly sent for inspection, to- gether with another beautiful work, Hooker’s ‘Rhododendrons of the Sikkim Himalaya.’ The company afterwards returned to the Museum, where tea and coffee were provided, and the evening concluded with conversation and a further inspection of the various objects of attraction there displayed. In reviewing the meetings of the season, a few remarks suggest themselves. It is to be regretted that our field meetings have been rather thinly attended, but this, no doubt, arose from the unfavourable state of the weather at the times when they were held ; for on no occasion have we been favoured with a thoroughly fine day. We may hope to be more fortunate in the ensuing season. The practice of breakfasting together at the field meet- ings has been discontinued on economical considerations, and for the purpose of affording an opportunity to a greater number, especially among the younger members to whom expense may be . a consideration, of joining in our excursions. To those who pre- fer comfort to economy, the option of breakfasting en route is still open ; and, when a very early hour of starting is fixed upon, a PRESIDENT’S ADDRESS. 325 subsequent breakfast may not be unacceptable. I would, how- ever, suggest that on those occasions an earlier dinner hour should be fixed upon. It has also appeared to me that the tract of country laid out for the day’s excursion has been occasionally too extensive, and that a shorter walk, in which the country might be examined more at leisure, would be desirable. I regret also that the practice of reading short papers after dinner has been so nearly discontinued. This has been principally occasioned by the length of the excursion and the late dinner hour not allowing time for the purpose. By a rule of our club, it was proposed to unite the pursuit of antiquities with that of natural history in our field excursions ; and it is therefore to be desired that the antiquaries of the dis- trict would more frequently join us on these occasions. The year now passed has been rendered memorable among the antiquaries of the north by a field excursion on a large scale——I allude to the pilgrimage along the line of the Roman wall, got up by Mr. Bruce,—in which some of our members joined. It may, however, be worthy of the consideration of those antiquaries who are members of our club, whether its meetings might not be made more available than hitherto for furthering the objects of their pursuit. Mr. Carr has set an example of communications on an~- tiquarian subjects, which we may hope that other members will be induced to follow. Very favourable notices of our Transactions have lately appeared in the Atheneum, the Literary Gazette, and the Botanical Gazette. It is encouraging to receive the meed of applause from such quar- ters. ‘We wonder,’ says the latter periodical, ‘that the success of this club has not caused similar associations to be formed in other parts of the country: if natural history had not hitherto been so wholly neglected in our educational systems, we should have one in every county town. May the next generation be more fortunate, and may the Tyneside Club endure until it finds itself a patriarch among Naturalists’ Field Clubs.’ A wish in which our members will no doubt heartily join. Although this address has extended beyond the limits I at first intended, I am unwilling to conclude without saying a few words 326 PRESIDENT’S ADDRESS. with respect to the mode and spirit in which natural history should be pursued. To search out nature’s treasures in the woods and fields is a rational, a healthful, and a pleasant pursuit, but the naturalist who confines himself to the collecting and naming of specimens only, losed one half the pleasure and instruction which it is calculated to impart. The works of nature can never be rightly understood without an examination of the structure of the plants and animals he collects. Their habits, their uses, and the beautiful adaptation of their organs to the functions they have to perform, afford a highly interesting enquiry, and, if the micros- cope be used, a still more wonderful and elaborate organization is revealed, extending even beyond the limits which our instru- ments can reach. In this way only can we truly appreciate the works of nature, and perceive how infinitely they surpass the rude efforts of human skill. Nor need we go far for examples, for rarity is not an element in this investigation ; *‘ Not a tree, A plant, a leaf, a blossom, but contains A folio volume. We may read, and read, And read again, and still find something new, Something to please and something to instruct, E’en in the noisome weed.’’ Messrs. Hardy and Bold presented the second part of their valuable ‘Catalogue of the Insects of Northumberland and Durham.’ Mr. John Hare, Newcastle; Mr. EH. C.

XII.—WNotice of the Occurrence, on the British Coast, of a Bur- rowing Barnacle belonging to a new Order of the Class Cirripedia. By AtBany Hancock, Esq. {Read at the Second Field Meeting, June 8, 1849.] I HAVE recently procured a very curious little animal belonging to the class Cirripedia, interesting not only on account of its modification of form, but also from its habit of burying itself in the substance of dead shells. The first individuals obtained were concealed in a broken specimen of Fusus antiquus procured by the Rev. G. C. Abbes, from the fishing boats at Whitburn, in the county of Durham, and fortunately preserved on account of VOL. I. vv 328 MR. A. HANCOCK ON A BURROWING BARNACLE the fine specimens of Cliona gorgonioides which it contained. Since then, I have got this Cirripede alive from the boats at Cul- lercoats, also in Fusus antiguus: it has likewise occurred in Buc- cinum undatum, from the same locality. And on breaking an old specimen of the former, which has been many years in my collection, it was found to have been extensively attacked by this novel parasite. Indeed almost every dead specimen of the large fusus, brought in by the fishermen, from deep water, is more or less affected by it; and the only wonder is that it should have remained so long undetected. This perhaps may be explained by the fact that this animal only attacks dead shells, and always, so far as I have yet observed, from the inside, so that it is scarcely to be seen until the shell is broken. The columella is the chief seat of the ravages of this creature, though the sides of the whorls do not by any means escape, especially if the indi- viduals are numerous. When quite young they enter the sound shell, and as they grow, enlarge their residence, which is always of the exact size and form of the tenant. It is interesting to remark how completely this animal, toge- ther with Cliona, destroys the shells of the larger mollusks of our coast. Cliona enters by the outer surface of the living shell, and rapidly spreads over the whorls; but it is not, until after death, that the inner surface becomes much affected by it. Then this Cirripede commences its ravages on the columella, which it soon deprives of more than half its substance, and afterwards so reduces it and the inner surface of the whorls, that this once secure retreat of the mollusk, losing all power to resist external forces, speedily becomes a crumbling ruin. Little is to be seen externally,—a small slit in the shell or matrix marks the position of the head. This slit, which is one- eighth of an inch long, is rounded and gradually enlarged towards one end, and tapers to a tolerably fine point at the other, which is generally a little bent. At this extremity the shell is mostly stained of a reddish hue—the stain being well-defined and of an ovate or fan-like form, increasing in size for about zths of an inch backwards, and having a few pale radiating lines, which converge towards the slit; on these lines there are a few minute BELONGING TO A NEW ORDER OF THE CLASS CIRRIPEDIA. 329 punctures irregularly distributed; but whether for functional purposes, or merely accidentally resulting from the close approxi- mation of the animal to the surface, could not be determined : they are not unfrequently partially closed up with calcareous matter. The stain is caused by the animal appearing through, which lies immediately below the surface of the matrix. This must be broken before the animal can be removed, and then it is found to be «:ths of an inch long, and ysths of an inch wide at the broadest part, of an irregular ovate form, considerably depressed behind, where it expands into a broad circular disc; and narrow and compressed in front, forming a sort of produced neck or head with a longitudinal slit on the upper surface ;—the general form resembling considerably, a Roman lamp, the slit representing the orifice for the passage of the wick. The produced portion, or head, corresponds to the valvular part of the pedunculate Cirri- pede, and contains the body and arms or feet,—the slit being analogous to the usual opening for the passage of these prehen- sile organs: there, are, however, no shelly plates whatever, the mantle being soft, fleshy and highly contractile, having the sur- face distinctly marked with fine longitudinal muscular fibres below; this part arches deeply into the matrix, and joins, rather abruptly, the under surface of the depressed disc-like portion of the animal, considerably behind the posterior end of the longi- tudinal slit. The margins of this slit are perfectly straight, thickened, and have somewhat the appearance of horn, but can- not be considered as forming distinct plates, though they com- pose, as it were, two valvular lips, which can be closed or opened at the will of the animal; in front they gradually blend with the mantle, behind, they are deeply notched, and each terminates in a projecting, slightly curved point. The external surface of these valvular lips, is furnished with numerous, minute, irregu- larly disposed, rather stout, curved spines, very transparent and of a crystalline appearance. ‘The circular depressed, disc-like portion of the animal, corresponding to the pedicle of the pedun- culate Barnacles, is slightly arched below, where it is pale, soft, fleshy, and as highly contractile as the anterior portion or head: 330 MR. A. HANCOCK ON A BURROWING BARNACLE the upper surface is flat, and has in the centre a broadly ovate, horny plate, most distinct in old individuals, but never entirely covering the part, the margins always extending beyond it. This plate is of a reddish horn-colour, and is generally furnished with a few indistinct radiating ridges and tubercles, corresponding to the radiating lines and punctures seen on the surface of the matrix. The animal, as before stated, lies immediately below the sur- face of the matrix, and is entirely free, except at a point just behind the slit, and in front of the horny plate, where there is a strong muscular attachment to the upper wall of the chamber. The longitudinal opening of the animal, corresponds to the slit on the surface of the matrix: this opening is kept pretty accu- rately plugged by the thickened valvular lips of the animal, ex- cept when it is in watch for its prey, at which time a slight opening in front permits the passage of the prehensile arms. These occupy the same position within the head or neck, as they do in the valvular part of the pedunculate Cirripedes, being placed immediately in front of the mouth. They differ however considerably from those of all other Cirripedes. The arms of this animal are only six in number; they are short and set ina circle on the extremity of a soft, fleshy, cylindrical pedicle, which is undoubtedly a prolongation of the true body of the animal ; the circle opens a little behind, in the direction of the mouth. The arms are each composed of three articulations, the first or lowest being much the longest, the last the shortest ; they are all fur- nished with a few hairs on the margins and extremities: the four arms next the mouth, have attached to their inner margins at the junction of the first and second articulations, an oval cushion- like body placed longitudinally, and wrinkled transversely, most probably for the purpose of prehension. Immediately behind the arms, projects a large conical body, containing the mouth, which is placed near the base in front towards the circle of arms. The greater portion of this body is composed of the upper lip, which differs considerably from that of the other Cirripedes. In this it is delicate and horny, being enormously developed and sur- mounted by a sort of rostrum, which projects upwards and for- wards, and terminates in a slightly produced obtuse point ; the BELONGING TO A NEW ORDER OF THE CLASS CIRRIPEDIA. 351 dorsal margin is carinated and minutely denticulated. There are three pairs of mandibles, as in the other Cirripedes: the outer pair are each apparently composed of three articulations, the third or terminal one being much compressed, forming an irre- gular oval plate, with the upper end terminating in a tooth-like process curved inwards: the two other articulations are much narrower, but on account of their minuteness and delicacy, their form could not be determined with accuracy. Only two articu- lations were observed in the second pair of mandibles; the inner or first articulation, is long, thin and straight, with the extremi- ties enlarged, and of an irregular form; the outer or second joint is very similar to that of the outer pair; it is however provided with two incurved teeth or spine-like processes, at the upper ex- tremity. The innermost or third pair of mandibles are rather wide, squarish plates, with three or four stoutish hairs on their upper margin. At each side of the mouth, there is a stout arm or palp which stands erect and reaches a little above the ridge of the rostrum ; the anterior margin of these arms is a little convex, the posterior a little concave; and they are furnished with stout, rather soft pincers about half the length of the arm, covered with numerous long hairs: at the root of the pincers there is an articulation, so that they can be either bent forward or carried erect ; there is also apparently an imperfect joint at the point where the arm joins the side of the mouth; but this could not be determined with certainty, as the horny membrane of the limb is so delicate that it is impossible to say whether the occasional flexure at this part, is owing to its flexibility or to an articulation. It is diffi- cult to say whether these arms represent what Dr. Martin-Saint- Ange names the jaw-feet in the pedunculate Cirripedes, or the two minute processes that are closely attached to the sides of the mouth, in these animals, and which are considered palps by some writers. They seem to occupy the place of the latter, though from their form, they have much the appearance of rudimentary anterior feet of the higher Crustacea. On each side of the rostrum, extending backwards, and a little way below the carinated ridge, there is a series of rather close-set 332 MR. A. HANCOCK ON A BURROWING BARNACLE transverse plates or hairs which taper towards their points, and are stout at their origin, where they are slightly bifid, and exhibit for some distance upwards, the appearance of two channels. There can be little doubt that these organs are for branchial purposes. The chamber in which the animal is lodged, is partially lined with calcareous matter secreted by the tenant ; this lining is very thin, and principally confined to the side walls of that part in which the anterior portion of the animal is lodged: here the lining gradually thickens as it approaches the margins of the slit, and passes a little beyond them, particularly towards its poste- rior termination. On looking down upon the slit, this shelly lining is seen distinctly projecting inwards from the margins, and exhibiting two or three longitudinal ridges marking periods of ‘growth, narrowing the opening backwards as the increase of the animal requires the advancement of the aperture in front. Shelly granules may also occasionally be seen filling up the curved pos- terior extremity of the slit. Notwithstanding the abundance of this animal, I have not yet been able to investigate the internal anatomy, many specimens having necessarily been destroyed in making the external exami- nations, and others suffered in attempts to remove them from their abode. This important part of the description must there- fore for the present, be left almost untouched. The cloak below is free for a considerable way backwards ; above, immediately behind the slit, it is united in front with the true body of the animal, and behind, where the broad disc-like expansion is covered with the horny plate, it blends with a thickish layer of parenchymatous matter. The stomach is long and narrow, and passing downwards and backwards from the mouth, bends rather suddenly forwards, and gradually tapering is continued into the cylindrical, fleshy pedicle which supports the arms, near to which it probably terminates. No caudal prolongation of this part was observed similar to that which is common to all the other Cirripedes; the generative organs are therefore probably modified in this animal. Adhering to the parenchymatous matter, beneath the horny plate, the eggs are found spread out into a leaf-like expansion BELONGING TO A NEW ORDER OF THE CLASS CIRRIPEDIA. 3930 co-extensive with this part of the animal; but whether or not this is really the ovarium could not be determined. It may be that the eggs have reached this position in some such way as they are supposed, by certain writers, to arrive in the pedicle of the pedunculate Barnacles. However, in this animal it is cer- tain that the ova are never arranged in lamine, at the base of the arms as in the other Cirripedes; but that they are hatched in the position in which they have just been described. Of this I have had ocular proof. In the early stages of development, the eggs are of a yellow ochre colour, and the yolk is round and much smaller than the shell; the yolk gradually assumes an elliptical form, and soon fills the shell, it afterwards becomes a little flattened on one side, and by-and-by, three processes develope themselves from this part ; these processes are the rudimentary arms: about this time a black spot, the eye, makes its appearance towards one end, and at the other the tail is seen to be forming; afterwards these parts enlarge, and gradually put on their perfect forms, while the ege mass assumes a full rose-colour. On examining an individual in which the eggs had been ex- posed, they were all found to be in a high state of development ; on applying a powerful lens, I was delighted to find that nearly all the little creatures were alive, and most of them struggling for liberty. I soon had the satisfaction to observe several dis- engage themselves, and launch forth into the surrounding fluid— free, natatory Crustaceans. In the course of a few hours nearly the whole were hatched, and the wine glass in which they were, exhibited a most animated scene. On holding it up to the light they were quite visible to the unassisted eye, as white points; but with the aid of a magnifying-glass, their motions could be accu- rately observed, and they were seen to resemble some of the Hn- tomostraca; their large single eye and general conformation showing their relationship to the genus Cyclops. They hung, as it were, suspended in the water, and every now and then dashed rapidly upwards with a fluttering, jerking motion. They com- ‘menced their ascent with great abruptness, and as abruptly be- came quiescent again ; and, once more hanging in the water, 334 MR. A. HANCOCK ON A BURROWING BARNACLE were seen to descend slowly and gradually with their feet spread out above, and their back downwards. They seldom or never moved horizontally, their chief object apparently being to ascend either perpendicularly or diagonally, and always in an inverted position, On placing a few of these minute beings under the microscope, each was found to be provided with a tail, the body being ovate, broad and depressed, having on the back an ovate shield tapering a little backwards, and with a broad interrupted line of bright rose colour towards the margins: it is to this line chiefly that the general mass of eggs has a rosy hue, as they approach matu- rity. The eye is large, and placed in the centre of the forehead ; it is of a very deep rose colour, almost black in some lights. The tail is more than half the length of the body, and passes from below the shield, and appears to be composed of two or three articulations: at first it is very stout ; but, rather suddenly nar- rowing, tapers gradually to a tolerably fine point and arches up- wards ; on the under surface, at the point of contraction, there is a small curved spine. There are three pairs of natatory legs placed well forwards, and indistinctly articulated ; the anterior pair are simple and furnished with a few long sete, at their ex- tremities ; the other two pairs are bifid, the anterior portion being much the stouter, and marked with several indistinct close-set articulations, towards the extremity; each articulation bearing, on its posterior margin, a long seta: the posterior branch of the limb is also furnished with set at its extremity. On each side of the head, there is a stout process a little arched backwards, with the point obtuse; these I am inclined to look upon as antenne, for they appear to arise from the head beneath the shield, though this could not be determined with certainty. It is possible enough that they are lateral prolongations of the shield, similar to the “ anterior horns ” of the larva of the pedun- culate Cirripedes. Whether so or not, the larva of this new animal may at once be distinguished from that of this division of the Barnacles, by the absence of the long spine projecting from the posterior margin of the shield. In other respects, it evidently shows a strong general resemblance to the larva of these animals, BELONGING TO A NEW ORDER OF THE CLASS CIRRIPEDIA. 330 The larva, then, as well as the characters of the animal itself, proves it to be a true Cirripede, while, in the former we see a confirmation of the relationship, shown by Thompson, to exist between these creatures and the Crustaceans. Indeed this ani- mal, in several particulars, exhibits a very close approximation to them. The shape of the arms or palps, by the sides of the mouth, resembles not a little the mandibles of the Nymphons, or the anterior feet of some of the higher forms; and the horny shield, overlying the expanded portion of the animal, gives some- what the idea of a rudimentary carapace: the rostrated upper lip, too, and setaceous branchie, have likewise a very crustacean appearance. x In these particulars, our new animal differs from the typical Cirripedes; but not more than in general form, which is very unlike that of either of the two great divisions of the class. The prehensile arms or feet, too, are highly characteristic in this, having, in fact, more the appearance of true feet than the cirri of the other Cirripedes ; there are only six, or three pairs, while in all the other Barnacles, there are double that number, or six pairs. In our animal, the last, or terminal joint, is shortest, and is sim- ple, having few, and comparatively short sete: the arms or feet indeed appear to be merely prehensile organs, laying hold of prey by the aid of the cushion-like swellings, before described as at- tached to their inner margins. The cirrigerous feet of the other Cirripedes, are also undoubt- edly prehensile, but in a very different manner. In these, each terminates in a pair of slender, much-elongated, and curled cirri, composed of numerous, minute articulations, furnished with a multitude of very long sete, arranged in double rows along the surface next the mouth. These sete diverge, so that when the cirri are spread out, the tips of the sete of the adjoining cirri cross each other, making a very complete net, which the Cirripede is for ever spreading out, and sweeping through the water in the direc- tion of the mouth. Its prey is thus secured, and nothing can escape that comes within the range of this simple and beautiful apparatus. It is not then by currents produced by the cirri, as usually asserted, that these creatures obtain their food; the feet VOL. I. ww 336 MR. A. HANCOCK ON A BURROWING BARNACLE form a prehensile net of the most efficient nature, and the only currents produced result from its action. In habit, too, this animal differs from all known Cirripedes ; none, I believe, but this species bury themselves in hard calca- reous bodies : some indeed partially conceal themselves in foreign substances, and all may be said, in a certain sense, to be parasi- tical. Z'ubicinella and Coronula are well known to sink deep into the skin of whales; but, in both cases, the whole of the valvular, or upper portion of the animal, is exposed; and as both are well protected by their shells, it is evident that this habit is not for defence, the object apparently being to avoid that resistance of the surrounditig element, occasioned by the rapid movements of this huge animal, and the consequent difficulty there would be in maintaining their hold of its smooth, contractile surface. Other genera, Prygona, Crusia and Acasta, are found concealed in corals and sponges ; none of them, however, excavate: these bodies simply grow round the Cirripede, and as it augments in size, which it does by increasing upwards, so does the coral or sponge advance withit. Lithotrya is the only genus of the class that has been described as actually excavating a habitation in hard calcareous bodies ; there is reason, however, to doubt the fact, as we shall see, by carefully examining Mr. Sowerby’s own figures in his ‘ Genera of Shells.’ This creature is a pedunculate Cirripede, and is stated to have at “ the base of the peduncle, a shelly appendage.” Forthe moment granting this to be true, it is evident that the holes it occupies, if made by itself, can only have been formed by either this appendage, or by the base of the pedicle before the shelly appendage was secreted. But on refer- ring to the figures just alluded to, it would appear that neither hypothesis is correct. In one of these figures, there is very cor- rectly delineated a couple of Serpule, adhering to the under sur- face of the basal appendage. Now it is pretty clear, that were this appendage used as a rasping surface, no Serpule could exist as represented ; and were the excavations effected before the for- mation of this appendage, it must necessarily partake of the shape of the base of the newly-formed chamber to which it would be closely adherent, as in the parallel case of Hipponya: it would BELONGING TO A NEW ORDER OF THE CLASS CIRRIPEDIA. 337 therefore be physically impossible for Serpule to develope them- selves on the under surface of such appendage. It is probable, then, that the basal plate of Lithotrya, is nothing else but a broken valve of either Clavagella, or of some small oyster that has been growing in the deserted abode, most likely of Clavagella, or perhaps of Lithodomus*. Clitia verruca, which is unprovided with a shelly base, certainly sinks slightly into the shells to which it adheres; but this cannot be considered a burrowing Cirripede. 2 Emarginula fissura ........

[Read Wednesday, December 12th, 1849.] WHILE examining a specimen of Sertularia pumila, taken from the rocks at Whitburn, under the microscope, I was struck with the appearance of what seemed to be a very minute parasitic zoophyte, several specimens of which were attached to different parts of the Sertularia. 366 MR. ALDER ON THREE NEW SPECIES OF ANIMALCULES. The body was of a vase or cup form, expanded at the top (fig. 1.), and set round with numerous pointed tentacles, abruptly thickened towards the base, and forming more than one row: they had very little motion, but were occa- sionally bent forwards, and the whole were sometimes slowly retracted. The body was attached to the Sertularia by a tolerably stout stem. Other specimens of the Sertularia were examined and found to have the same parasite, which was itself infested by still more minute parasitical bodies of the family Lacillaria. In addition to the first species of supposed zoophyte, another, rather smaller, was also detected, (fig. 2). Its body was of an ovate form, with a very slender and shortish stem: the tentacles were capitate, or knobbed at the end, not so numerous as in the first species, and placed in a single row round a narrow disk. Under the impres- sion that these animals belonged to the class of zoophytes, I sent drawings of them to my friend Dr. Johnston, who informed me that they represented something with which he was not acquainted, and that possibly I had got a new form of Campanularian zoophyte. A more careful examination, however, of these delicate little crea- tures, which were so minute as to be only just visible to the naked eye, convinced me that their organization was much more simple than is to be found in the true polypes, and that they must be considered to belong to the class Infusoria. I afterwards found both these species on Sertulariz at Cullercoats. I have since met with another species of these polype-like animalcules inhabiting fresh water, (fig. 3). It occurred in Crag Lake, on the stem of the new species of Paludicella found there, and somewhat resembles the smaller marine species already described, but is perfectly distinct from it as its habitat would lead us to expect. The body of this lacustrine species is pear-shaped, or, perhaps, rather bell-shaped, with a distinct rim round the top, and a single circle of delicate capitate feelers, which, as in the former instances, were retractile. The stem was long and slender. MR. HANCOCK ON THE FRESHWATER BRYOZOA, ETC. 367 The British Animalcules are very imperfectly understood. With the exception of the beautiful tribe of Vorticelle, whose relationship is very remote, there are not any published native species bearing the least resemblance to those here described. The genus Acineta of Ehrenberg comes nearest to them. Acineta mystacina, found near Berlin, somewhat resembles our lacustrine species, but its form appears to be much more simple, and the tentacles rise irregularly from different parts of the body. It is probable, therefore, that these animalcules are undescribed, and their discovery is not void of interest, on account of their forming a more perfect lnk be- tween the Infusoria and the Campanularian zoophytes than any hitherto known. The great class Infusoria, in its present form, includes a hete- rogenous assemblage, which at some not very distant period must be broken up ; and it will then probably be found that the infu- sory animalcules contain the first rudimentary forms of nearly all the invertebrate types. XVII.—On the Anatomy of the Nreshwater Bryozoa, with de- scriptions of three new species. By AuBany Hancoor, Hsq. [Read Wednesday, December 12th, 1849.] Durine a ramble made last July, in company with the Club to the Northumberland lakes, | was fortunate enough to find two or three species of Bryozoa. Since then I have revisited the locality twice, and on each occasion additional species occurred. Thus six or seven forms of these interesting animals have been found to inhabit two of these lakes, namely, Bromley Lough and Crag Lough. ‘Three of the species appear to be undescribed ; these I propose to characterize towards the close of this commu- nication, giving previously an account of the anatomy of the fresh- water Bryozoa so far as I have been able to determine it. Ad 368 MR. HANCOCK ON THE ANATOMY OF THE FRESHWATER Amongst the known species was a fragment of Alcyonella, most probably A. stagnorum ; but its characters could not be deter- mined on account of the imperfection of the specimen. rederi- cella sultana occurred abundantly, and of very luxuriant growth, spreading over the under surface of stones in patches of three or four inches’ extent. Of the new species, two belong to Plumatella and one to Paludicella, a rare genus, of which there was but one species previously known, and that, I believe, had been found only in Ireland, and in two or three localities on the continent. The anatomy of the freshwater Bryozoa had been very little studied, on this side of the Channel, before Professor Allman took up the subject, and he has handled it so well that little is left to be done. Indeed so complete are the results of this naturalist, that, perhaps, the publication of my own may appear almost un- necessary. My investigations, however, carried on, as they have been, perfectly independent of the researches of others, may not be without some value even where novelty is wanting. Micro- scopic investigations conducted by the aid of transmitted light are liable to error. Frequent examinations in such cases are therefore necessary, and observations independently prosecuted are of peculiar value. Consequently, I do not hesitate to give the result of my own labours on this subject, fraught as it is with difficulty, not fearing to mislead in a path already so well trodden. Of the anatomy of these animals I shall have to confine my- self almost entirely to that of Plumatella, Fredericella and Palu- dicella. Of Alcyonella I can say but little, having seen only an imperfect specimen, and none of the other freshwater forms have come under my notice, Plumatella and Fredericella resemble each other very closely in their anatomical structure, notwithstanding the external difference of their polypes. Paludicella, however, shows some very interesting modifications, particularly in the muscular sys- tem: but before entering on the internal anatomy, it will be necessary to examine the characters of the polypidom, and to trace its relationship to the polype. The polypidom of Plumatella Allmani, Pl. VI, figs. 3, 4 and 5, and of Fredericella sultana is tubular, branched and carinated BRYOZOA, WITH DESCRIPTIONS OF NEW SPECIES. 369 on the upper surface ; the walls opaque, tough, and membranous, inclining to horny. Those of the latter, when examined through the microscope, exhibit a sort of dendritic structure; the divisions or branches passing in an irregular spiral direction round the tube, are flattened, and extensively anastomosing, form for the most part a dense tissue, nowhere more open than just to display the branched character. The walls of Plumatella do not in the least exhibit this structure. In Paludicella the polypidom, fig. 2, is likewise branched and tubular, but not carinated; it is mem- branous or horny, and becomes enlarged and contracted at cer- tain intervals, dividing the whole, as it were, into cells or com- partments, the external surface being smooth and very glossy. All these genera have the polypidom lined with a delicate membrane—the tunic, Pl. IV. figs. 4 6, b & 5 k, and Pl. V. fig. 1 6, which is attached only at certain points to the inner surface of the external tube or cell-wall. This, in Plumatella and Fredericella, becomes excessively delicate towards the orifice, where it apparently blends with the tunic. But in Paludicella the union at this point of the horny wall and tunic cannot be mistaken, though the blending is so gradual that it is impossible to say where one ends and the other begins. And when this polype is exserted, there is a delicate membranous cup, Pl. V- fig. 1 d, projecting upwards from the inner surface of the mouth of the cell. This cup is the homologue of the circle of setz sur- rounding the aperture of Bowerbankia and other marine genera. In Paludicella, the tunic is sprinkled with large nucleated cells, fig. 4 m, and at certain intervals bends abruptly inwards, figs. 1 and 2 wu, r, dividing the polypidom into cells at the points indi- cated by the constrictions in the horny tube. Thus each polype is isolated, is contained in fact within a distinct membranous cell, the end-walls of which abut against the end-walls of the adjoining cells. The divisions are therefore double, and being of living membrane, and in contact, it is probable that all the inhabitants of the polypidom are in some degree connected in vital action. The end-walls are considerably thickened in the centre, forming a bulb or boss projecting into the cell. The polypes of Fredericella are not separated the one from the other, 370 MR. HANCOCK ON THE ANATOMY OF THE FRESHWATER though a few divisions appear to exist at distant points. Thus it would seem that groups of animals are associated together as it were in one tube. Neither in Plumatella are the polypes separated. The polype lies in the longitudinal axis of the cell, Plates ITI. and V. figs. 2, 2, being provided with numerous muscles for pro- trusion and retraction. It is held in its place principally by a membranous tube—the tentacular sheath, Pl. III. fig. 2 m, x, and Pl. V. fig. 2 d’, d’, which blends with the inverted lips of the tunic, Pl. III. fig. 2 7, a little below the orifice of the cell, and continuing downwards within the cell encloses the bundle of re- tracted tentacles, and is attached round the tentacular disc a’. Digestive System.—The organs of digestion, comprising nearly the whole of the polype, float freely in the visceral cavity. The entrance to the alimentary canal is furnished with tentacles, Pl. III. fig. 1 6; these arise from a margin surrounding the oral opening in two different fashions; in the one they form a com- plete circle round the mouth, in the other they are arranged in a crescentic manner, the limbs of the crescent being two arms, Pl. IV. figs, 1, 2 & 3c, e& c, extending from the sides of the mouth, fig. 3 a, having their bases confluent and with a row of tentacles on their inner and outer margins. Paludicella and Fredericella, Pl. V. fig. 1 f, and Pl. III. fig. 1 6, are examples of the first mode of arrangement; and Plumatella, Pl. IV. figs. 1. 2 & 3, and Alcyonella of the second. In Paludicella the tenta . cles, when spread out, form a very exact inverted cone, closely resembling the shape they assume in some of the marine species. The base or disc supporting the tentacles is not exactly circular in Predericella,; in this genus it is a little flattened at the point corresponding to the space between the oral arms in Plumatella; and there is also a delicate transparent membrane, Pl. III fig. 1 c’, c, uniting the bases of the tentacles. In these respects Frede- ricella shows an approximation to those with oral arms, or as it is generally termed, a crescentic disc. In these there is always a similar membrane, Pl. IV. figs. 1, 2&3, f&d, at the base of the tentacles, and in all of them, as well as in /redericella, this membrane is attached to the external surface of the tenta- cles, and is much wider at the margin than the spaces between BRYOZOA, WITH DESCRIPTIONS OF NEW SPECIES. 371 them, and, consequently, it bags out, giving to the upper portion a flounced appearance, particularly in the latter, Pl. III. fig. 1 ¢. The tentacles themselves, in all these genera, are rather stout and linear with the end obtuse; they have the appearance of being tubular, as have likewise the oral arms of Plumatella : the tentacles are clothed with long cilia, which vibrate upwards on one side, and downwards on the other, in the same manner as de- scribed in the marine species ; and as in them, when the polype is retracted, the tentacles are drawn down in an erect position, having first been brought together into a compact linear bundle, Pl. III. fig. 2 a, and Pl. V. fig. 2d. They do not appear to be at all contractile, and in all the species are transparent and almost homo- geneous in their structure. There can be little doubt that they are not merely tentacles, but that they are likewise respiratory organs: food is brought to the mouth by their ciliary currents, ‘and also by the action of the tentacles themselves, one or more of which may frequently be seen bending suddenly inwards, and securing such particles as come within their reach. They occa- sionally act in concert in the capture of animalcules, by bringing their tips together, thus forming, in those with a circular disc, a very elegant oval cage, within which the imprisoned prey may be seen for an instant or two dashing about, previously to passing into the cesophagus or to liberation, which not unfrequently hap- pens, the captive proving distasteful to the polype. The tentacles then may be considered prehensile, labial, or oral appendages, not- withstanding their respiratory function, and as such they area portion of the alimentary system. The oral orifice of Plumatella is semicircular, Pl. LV. fig. 3 a, and protected by a strong, rounded, fleshy valve, 6, which, arising from the side of the mouth at the point on the inner margin of the cresent, where the two arms unite, projects upwards and slightly overhangs the opening. This valve is completely under the control of the animal, and can be made to act as a sort of operculum, closing the orifice to prevent the admittance of food ; or it can be used to force food into the pharynx. The mouth, Pl. IIT. fig. 1 d, of Predericella is likewise semicircular, and is also provided with a similar valve, e. It is immediately behind 372 MR. HANCOCK ON THE ANATOMY OF THE FRESHWATER it that the tentacular disc is a little flattened, proving that this point corresponds to the space between the arms in Plumatella ; indeed, in some points of view, the angles formed by this flatten- ing have not a little the appearance of rudimentary arms just sprouting. The cesophagus descends at once in a straight line from the oral opening. In Fredericella, Pl. III. figs. 1 f & 2 6, it is rather short and wide, and the walls, which are thick and fleshy, are parallel throughout, except at the commencement, where they are a little bulged, forming a sort cf pharynx which is lined with vibratile cilia: the other extremity communicates with the stomach by a distinct valvular orifice, Pl. III. figs. 1 g & 2e, the cardiac, projecting downwards. The whole surface is covered with minute circular cells resembling very much the peculiar structure observed in the marine species, and pointed out by Dr. Farre, in his valuable paper on the Marine Ascidian Polypes published in the ‘ Philosophical Transactions’ for 1837, The stomach, figs. 1 2 & 2 d, is more than twice the length of the cesophagus, tapering slightly downwards and truncate above ; the lower extremity being obtuse: the walls, lke those of the oesophagus, are thick and fleshy, and are covered with numerous, minute, close-set cells of a glandular character. The pyloric orifice is circular and well marked, and has the appearance of being guarded by a sphincter muscle; it is likewise supplied with vibratile cilia which extend some little way into the stomach. This orifice is situated above, at one side and a little below the cardiac opening. The intestine, figs. 1 & 2, %, ¢, is straight, and a little longer than, and nearly as wide as, the esophagus, with which it hes in contact, and to which it is apparently attached ; the pyloric extremity is obtusely pointed, and communicates by the side with the stomach ; from thence the intestine tapers a little upwards towards the anal extremity, which, turning outwards, passes through the tentacular sheath just below its attachment to the disc supporting the tentacles, and there terminates in an obtuse perforated point, figs. 1 & 2 7 & f, which can be either protruded or retracted, to a considerable extent, at the will of the animal. The whole of the alimentary BRYOZOA, WITH DESCRIPTIONS OF NEW SPECIES. 375 canal is highly irritable, particularly the esophagus and stomach, in the walls of both of which, minute, transverse striz are dis- tinctly visible, probably indicating the presence of muscles. The stomach is perpetually in motion when the animal is displayed, contracting in an undulating or vermicular manner from above downwards. The contractions of the esophagus, too, are very decided on receiving food, which for a second or two rests in the enlargement, and is then hurried into the stomach with great rapidity. The alimentary canal of Plumatella and Alcyonella does not vary in any important manner from that of /redericella. In the two former, however, both the csophagus and stomach are shorter than they are in the latter genus. In all these genera no disturbance of the parts of the aliment- ary canal takes place on the retraction of the polype : the animal sinks into the cell with the csophagus, stomach and intestine erect as they were when the tentacles were exserted and in full play. Not so, however, in Paludicella, Pl. V, fig. 2; in this genus the alimentary canal is doubled upon itself when the polype is retracted ; and, moreover, the parts are somewhat modified, approximating this form more closely to that of the marine species. When the animal of Paludicella is protruded, the cesophagus, fig. 1 h, is observed to be long and slender, and to have a dis- tinct pharyngeal dilatation at the commencement, where vibra- tile cilia can be seen in vigorous action. It communicates with the upper extremity of the stomach by a circular orifice, fig 2 f. The stomach, fig. 1 2, is rather short, considerably enlarged above and tapering to the inferior extremity, where it 1s rounded : the walls are thick, and apparently filled with yellowish brown coloured granules, probably hepatic as in the marine species. The intestine, 7, arises from the superior extremity close behind and a little above the cardia. The pyloric opening is well de- fined and circular; soon after its origin the intestine is sud- denly enlarged, forming an oval swelling, &, in which the feces may be seen collecting ; it contracts above this swelling, and continues afterwards for nearly its whole length of equal diame- 374 MR. HANCOCK ON THE ANATOMY OF THE FRESHWATER ter; it passes upward in a straight line parallel with the ceso- phagus, but unattached to it, and terminates in a rounded anal extremity, 7, immediately below the base of the tentacles where it perforates the tentacular sheath. The upper end of the stomach, close to the pyloric orifice, is furnished with vibratile cilia, and here the alimentary matters may be seen rapidly rotating by their influence. The feces are formed into small pellets, which, coming from the enlarged portion, pass up the intestine and are expelled at the anal orifice. The whole of the canal is as highly irritable as in the other species ; the stomach undulating from above downwards in the same manner, and the cesophagus is equally expert in transmitting food to the stomach. But neither in Paludicella nor in the species before alluded to does the pharyngeal swelling exhibit in any marked manner, the sudden puffings and contractions so conspicuous in the marine species, and noticed originally by Dr. Farre. On retraction of the polype, the alimentary canal of Paludi- cella is doubled upon itself in much the same way as in Bower- bankia. The basal disc of the tentacles is then brought down as far as the upper extremity of the stomach, and the consequence is that the intestine, fig. 2 h, is doubled upon itself a little above the enlargement, 7, and the cesophagus, e, is forced down by the side of the stomach, g, and turning upwards again is bent into the form of an 8. Vascular System.—This appears to be entirely wanting in these animals: a species of circulation nevertheless exists. I have seen, on two or three occasions, a pretty regular flow of the fluid in the visceral cavity of Pluwmatella and VFredericella. Under ordinary circumstances no fluid can be recognized in this cavity, from the apparent deficiency of blood-globules or corpus- cles of any kind. Such however probably exist, but the thick- ness and opacity of the cell-walls are sufficient to prevent the detection of minute bodies of this nature. On the occasions alluded to, some of the tissues of the animal appear to have been ruptured, and small fragmentary particles, mingling with the contained fluid, were perceived moving in certain directions. By the aid of these particles, which were numerous and of various BRYOZOA, WITH DESCRIPTIONS OF NEW SPECIES. 375 forms and sizes, it was easy to ascertain that the fluid which bathes the polype circulates in a regular manner within the cavity in which the viscera float. There can be no doubt that this circulation is caused by the action of cilia which cover the inner surface of the linmg membrane or tunic, and also clothe the external wall of the retracted tentacular sheath. The cur- rent flowed regularly and steadily; but when the floating particles approached the surface of the tunic or tentacular sheath, their motion became accelerated in a manner that sufficiently evinced the presence of vibratile cilia. Those on the tunic chiefly determined the direction of the current, which went with great regularity up one side, crossed over at the top of the cell, and then went down the other side ; it crossed again, in an opposite direction, a little below the stomach, and so completed the circuit. It was not difficult to ascertain that the cilia of the tunic on one side of the cell vibrate upwards, on the other side _ downwards ; and that all those, on the tentacular sheath, vibrate upwards. On one side therefore the currents of the sheath and tunic oppose each other ; and consequently an eddy was visible near the top of the cell. Tt is quite evident then that fluid circulates within the visceral cavity. What is the nature of this circulation? Is it merely respiratory, or is it nutritive? It can scarcely be considered an aérating current, as there is no visible communication between this cavity and the external water; and indeed if an orifice exists, it must be minute and under the control of the animal, or the protrusion of the polype could not be effected in the manner to be afterwards described. It is more likely to be for the purpose of nutrition,—standing, indeed, in the place of a vascular system. The fluid must therefore hold in suspension the products of digestion. These may be supposed to exude through the walls of the intestinal canal, probably from the enlarged portion of it in Paludicella, and perhaps also from the upper portion of the stomach ; and passing into this circulation will go at once to nourish the various organs of the animal, all of which are bathed with this vivifying fluid, except the ten- tacles, which we shall afterwards see, in all probability, receive B3 376 MR. HANCOCK ON THE ANATOMY OF THE FRESHWATER blood into their interior, for the purpose of aération. In this way, too, we can understand the nourishment and growth of the tunic and the maintenance of the buds (which germinate from it) until they are able, by the aid of their own tentacles, to procure food. In no other way can the development of these buds be so easily explained. The membrane in which they take their origin must either be supplied with the nutritive fluid in this way, or by the agency of vessels; but none can be discovered either in the tunic or elsewhere. The external cell-walls, whilst in a growing state, must also be nourished by the tunic, which we have seen is united to the external walls at the orifice of the cell. The respiratory function we have stated to be exercised by the tentacles, but there can be no doubt that all the exposed parts will assist in aérating the blood. The tentacles are hollow, and though I could not detect any fluid within them, it is probable that the blood finds its way into their tubular cavities through the basal dise ; and as they are clothed with strong vibratile cilia which keep a constant flow of the oxygenating medium, over their surfaces, they would appear well adapted for breathing organs. It is, however, difficult to understand how the oxyge-= nation of the blood goes on when the polype is retracted; for, at this time, the orifice is completely closed by the folding in. of the lips of the cell, and by muscles provided for the purpose. Pro- fessor Allman has supposed that the tube retractors of Paludicella exercise the function also of opening the aperture, when in this state, for the purpose of admitting the surrounding fluid. But I have seen nothing to warrant such supposition ; and indeed the tentacles being then packed close together within the sheath, the cilia cease to vibrate, and there is no room in which the water can flow around them, even supposing an opening to be so maintained. The tips of the tentacles, too, of Paludicella, and of several of the marine species when retracted, are generally bent down in a manner to forbid the flow of any fluid whatever amongst them. It would therefore seem clear, that when not in action the oxygenation of the blood must almost, if not entirely, cease in these polypes, as 1t must do in most of the Mollusca when closed up in their shelly armature. ae fod BRYOZOA, WITH DESCRIPTIONS OF NEW SPECIES. 317 Nervous System.—Some years ago Professor Allman discovered a ganglion in these animals, and has more recently ascertained the existence of nerves. I have also detected a large ganglion, Pl. III. fig. 1 &, in Plumatella and Fredericella. It is situated just below the entrance to the csophagus, on the external sur- face, close to the base of the tentacles and just above the anal orifice. It is therefore placed between the oral arms in Plwma- tella, and in Fredericella at the corresponding point. In the latter I have observed two or three nerves passing from the ganglion upwards in the direction of the tentacles, and one apparently going to embrace the oesophagus ; another that comes from the lower extremity of the ganglion may also be seen pas- sing downwards close to the esophagus. This is all I have been able to make out respecting the nervous system, though undoubtedly more is to be learnt. © Muscular System.—There are three distinct set of muscles in Plumatella and Fredericella; one for the retraction of the polype, another to assist in the act of protrusion, and the third probably accessory in closing the orifice. The first and most conspicuous set of muscles, the polype retractors, Pl. III. figs. 2 g, g &4f, and Pl. IV. figs. 4 g & 5 7, 2, is divided into two equal bundles, one passing on each side of the polype. These bundles are composed of numerous, stout, isolated fibres, having their origin in the walls of the cell a considerable way below the retracted polype ; and passing upwards have their superior ex- tremities inserted at the tentacular disc or base of the oral arms and at the upper portion of the esophagus. There are also two sunilar bundles of muscular fibres in Alcyonella, but in this genus they have their origin at, or close to, the bottom of the cell. When the animal of Plumatella is exserted, two or three of the stoutest, Pl. III. fig. 4 g, of these fibres are seen to be attached on each side further forward than the rest at the base of the oral arms. Also in /redericella similar fibres are inserted at the corresponding parts of the tentacular disc. These stout fibres have their origin a little lower down the cell than the rest. _The function of these two bundles of muscular fibres cannot for a moment be mistaken: they are for the purpose of drawing 378 MR. HANCOCK ON THE ANATOMY OF THE FRESHWATER the polype back into the cell ; and when it is so withdrawn, the fibres of this, the most powerful muscle of the animal, may be seen in a relaxed state and bent upon themselves in a loose un-. dulating manner about the tentacular disc, and downwards to their origin. The few strong fibres alluded to, undoubtedly assist in the retraction of the polype; but are also apparently the principal agents in rotating the head, so to speak, of the polype when exserted. The second set of muscles, Pl. III. figs. 1 & 2 m, h, is composed of a circle of stout, isolated, radiating fibres, all placed in the same horizontal plane, considerably apart from each other, and attached by their outer extremities to the inner surface of the tunic, some way below the opening; their inner extremities converging towards the tentacular sheath, are attached to it about one-third from its superior termination. Plwmatella has fifteen or sixteen of these fibres, /redcricella about fourteen. Their arrangement is perfectly symmetrical. They are for the purpose of preventing the inversion of the whole of the tentacu- lar sheath, on the protrusion of the polype; and thus to confine the oral extremity within a convenient distance above the mouth of the cell. The true value of these muscles will be fully understood if we refer to the marine genus Lowerbankia, in which they are deficient, and of course the tentacular sheath can be completely inverted, and accordingly the animal is enabled to reach toa greater distance than it could otherwise have done. But an ap- paratus of extraordinary beauty is provided to obviate the incon- venience that must have arisen from the great elevation of the tentacular dise, above the support of the horny cell. This is effected by what may be considered an elongation upwards of the cell. Numerous setz bound together by a membrane, are attached to the lips of the orifice, so that when the polype is exserted, they stand up in a circle surrounding the lower part of the exposed portion of the animal, and give support to it. By this means, the far-outstretched tentacular disc is brought com- pletely under the control of the muscles for directing its move- BRYOZOA, WITH DESCRIPTIONS OF NEW SPECIES. 379 ments.* We thus clearly see that this set of radiating muscles is a compensation for the deficiency of the circle of sets in the freshwater polypes. The third set of muscles, figs. 1 & 2 n, 2, consists of numerous, separate, fine thread-like filaments, placed considerably apart, without order, but in the same radiating manner as those last described, immediately above them and extending upwards to the termination of the cell. These filaments have their outer extremities attached to the inner surface of the tunic; and con- verging towards the axis of the cell, their inner extremities are attached to the upper portion of the tentacular sheath and the inverted margin of the tunic. These fibres are equally numerous and fine in both Plumatella and Fredericella, and appear to be for the purpose of assisting in closing the orifice, acting in harmony with the contraction of the upper portion of the tenta- cular sheath and the inverted lips of the orifice. They may, acting in the opposite direction, also assist in opening the channel, but the tentacles themselves would appear quite adequate to force a passage on the relaxation of the contractions about the orifice. The function of these fibres is in fact to keep in unison the tunic near the opening, and the upper portion of the tentacular sheath. The upper portion of the tentacular sheath and inverted lips of the tunic are highly contractile, and it is by their agency principally that the orifice is closed when the animal is retracted. I have not, however, been able to detect any muscular fibres for the purpose, though at the point, Pl. III. fig. 2 7., where the inverted lips of the tunic join to the tentacular sheath, it is * Dr. Farre has described this apparatus in his paper so frequently referred to, but seems scarcely to have arrived at a full knowledge of its function. He considers that it is ‘‘ for allowing of the freest possible motion to the upper part of the body, in its expanded state, to which it affords at the same time support and protection.”? On examining the animal in action, it is evident that the use of the apparatus, is, as I have pointed out. The circle of sete is then seen to compress the lower portion of the extended polype; and when the tentacular disc moves from side to side, the neck always bends from the top of the sete, at a decided angle, and does not gradually arch away from the lips of the cell, as might be expected, were this contrivance for the purpose of giving flexibility. The delicate membrane uniting the sete, is strengthened with numerous, minute, transverse fibres, forming the whole into a powerful sphincter, thus giving great firmness to the part. By this arrangement, Bowerbankia is enabled to raise the tentacular disc far above the polype-cell, and yet to remain as perfectly under the control of the rotatory and retractor muscles, as is the tentacular disc of Fredericella and Plumatella, in both of which it is confined close to the orifice of the cell by the action of the radiating muscular fibres. 380 MR. HANCOCK ON THE ANATOMY OF THE FRESHWATER suddenly constricted as if by a powerful sphincter muscle. In fact the whole of the tunic is undoubtedly contractile, yet in no part of it have I detected muscular fibres. By the contraction of this lining membrane, the capacity of the visceral cavity is diminished ; and thus, by the pressure of the contained fluid, the protrusion of the polype is effected. This matter, however, will be discussed more fully when we come to speak of this portion of the anatomy of Paludicella. To understand the combined action of the various sets of muscles in Plumatella and Fredericella, we have only to watch the animal when about to issue from the cell. The first change observed is the contraction of the tunic, Pl. III. fig. 4 7, 7, and Pl. IV., fig. 4 b, the walls of which are brought nearer together towards the lower portion of the cell. The pressure thus occasioned, on the contained fluid, compels the polype to begin its ascent ; at the same time the sphincter contraction of the upper portion of the tentacular sheath relaxes, so that the bundle of tentacles can force their way without difficulty. As the polype gradually advances upwards, the circle of strong radiating muscles comes into play, and it is a sight of no little interest to watch them drag upon the tentacular sheath, allowing the inferior portion of it to roll up- wards attached to the tentacular disc. As soon as the ascent is arrested by these muscles, the sheath being inverted as far as they will permit, protrusion is complete, and the tentacles at once assume their proper arrangement. The muscular apparatus of Paludicella differs in some respects from that of Plwmatella and /redericella. In the former there are six sets of muscles—three in connexion with retraction, two with protrusion, and one for closing the orifice on the retreat of the polype. Of the retractors, one set acts directly upon the animal, the other upon the tubular orifice of the cell. The former set, Pl. V. fig. 1 0, the most powerful in the animal, is similar to the tentacular retractors of Dr. Farre : it differs. only from the polype- retractors in Plumatella, and the other genera already spoken of, in not being divided into two bundles. It is composed of numerous, stout, long, linear fibres, originating from the inner surface of the anterior wall of the cell, more than half-way down ; BRYOZOA, WITH DESCRIPTIONS OF NEW SPECIES. 381 then passing up in front of the polype, the superior extremities are inserted around the base of the tentacular disc. These fibres draw the polype down into the cell, and like those of the same muscle in the other Bryozoa, when unemployed, lie in a somewhat cramped and disordered state, fig. 2 J, 1. The second and third sets of muscles are the tube-retractors ; the former or inferior, figs. 1 p & 2 m, m, is much the larger; it is composed of four compressed bundles of stout, linear fibres placed close together, but distinct from each other. These bundles are associated together in pairs, one on each side of the tube ; the inferior ends of these pairs of bundles arise wide apart from the posterior wall of the cell opposite the orifice. As they pass up the tube, the bundles converge,and reaching within a short distance of the lips of the orifice, they are inserted upon the inner surface of the tube-walls at four opposite points ; the fibres of each bundle being attached one above the other in the same longitudinal plane. This peculiar arrangement causes the margins of the orifice to fold into four portions on the retraction of the tube ; and its end, fig. 3, consequently assumes a square form, the angles corresponding to the insertions of the muscular bundles. The third set of muscles, figs. 1 ¢ & 2 », n, the superior tube- retractors, are made up of only four fibres, two on each side of the cell, having their origin immediately below that of the set just described ; their other ends are attached to the inner surface of the tube above the insertion of the inferior set, and at the base of the membranous cup, fig. 1 Z, before alluded to, at the mouth of the cell. The inferior and superior tube-retractors are homologous to the double set of opercular muscles described by Dr. Farre, in the marine species, differing only from those in Bowerbankia densa by being divided into four bundles instead of into three, as they are in that species. The action of these muscles is obvious. The superior retractors, having their insertion at the base of the membranous cup at the mouth of the cell, draw it down base first in the axis of the tube, at the same time folding in around it the lips of the cell. The inferior set then taking up the work, com- plete the inversion of the tube. Dr. Farre, however, supposed that the opercular muscles were not merely for drawing the tube 382 MR. HANCOCK ON THE ANATOMY OF THE FRESHWATER in after the retreating animal, but also for the purpose of closing the orifice. Professor Allman has pointed out the error of this opinion, and endeavoured to explain the closing of the orifice by the pressure of the fluid within the cell, against the walls of the inverted tube. We shall directly see, however, that this theory is unnecessary, there being special muscles provided for the purpose. Professor Allman is likewise disinclined to believe that the opercular muscles are really tube-retractors, as he supposes the muscles for drawing in the polype are sufficient for the purpose also of drawing in the tube. Were these latter muscles used to invaginate the tubular orifice of the cell, we should expect to find find them in action so long as the animal was retracted ; but we have already seen, that when the polype is in this state, they are invariably relaxed and lie in a disordered undulating manner, perfectly at rest. The tube-retractors, on the contrary, are always tense and in vigorous action during the retracted state of the polype, evincing, I think, in a satisfactory manner, that their function is to retract the tube, and to maintain it in an invagi- nated state—unless we are to suppose that they are constantly employed in keeping open the channel, as suggested by Professor Allman. They will certainly have a tendency to pull asunder the walls of the inverted tube, yet I have never seen the channel thus opened, although these muscles are never otherwise than as represented in Pl. V. fig. 2, when the polype is retracted. And, moreover, the tips of the tentacles, as exhibited in this figure, are frequently doubled down, showing that the tentacular sheath must be to some extent relaxed, and that there is no stress what- ever on it, as there would be were the polype-retractors used to draw in the orifice. The fourth set of muscles to be described is for closing the orifice. This set is composed of two sphincters: one, fig. 2 0, of these, is made up of several fibres passing round the tube at the place of insertion of the inferior tube-retractors, and is of con- siderable breadth ; the other, », is formed of only two or three fibres, which encircle the same tube at the insertion of the superior tube-retractors. The action of these sphincters cannot be mistaken : they effect the closing of the orifice on the retraction BRYOZOA, WITH DESCRIPTIONS OF NEW SPECIES. 383 of the animal, being at the same time antagonistic to the opening tendency of the tube-retractors, which, diverging from their insertions, must, in some measure, bring the walls of the inverted tube asunder. These sphincters are not readily distinguished, but, having seen them in several individuals, I have not the slightest doubt of their existence. Deeming, however, that it would be satisfactory to see whether a similar apparatus, for closing the orifice, could be found in the marine species, [ examined specimens of Bowerbankia, and had the satisfaction of detecting sphincter muscles in the same situations. At the point of insertion of the inferior tube-retractors—according to Dr. Farre, of the upper set of opercular muscles—the circular fibres are very distinct and numerous, forming a large portion of the inverted tube into a broad sphincter. These fibres are so conspicuous that it seems strange how they could have escaped the notice of so close and accurate an observeras Dr. Farre. It is possible enough, however, that they might be less developed in the species examined by him.* The sphincter, at the point of insertion, of the superior tube- retractors is not readily observed ; but when the polype is exserted there can be no doubt of its existence. The fifth set of muscles, P1.V. figs. 1 & 5 ¢, A, isin connexion with the tunic or lining membrane of the cell, and is precisely similar to the parietal muscles described by Dr. Farre, in the marine species. ‘This set is formed of short, transverse belts, arranged in pairs, considerably apart from each other, which are to be found almost from end to end of the cell, but most conspicuously towards the lower extremity. There appears to be two sets of these fibres, one down the back, the other down the front of the cell ; but I could not arrive at any satisfactory conclusion respecting * In the species examined by Dr. Farre, and named by him Bowerbankia densa, the tube-retractors have a “ triradiate arrangement,’’ and, consequently, the orifice is puckered into three folds, when the polype is retracted. The species referred to, in the text, we have seen, has four such folds, the tube- retractors being divided into as many bundles. The circle of tentacles also assumes a different form in the two species: in that examined by me, the tentacles rise from the disc in a straight, slightly diverging line, and arch considerablv outwards at the tips. In Dr. Farre’s species they arch outwards immediately above the disc, and are very little recurved at the tips. It is therefore pretty evident that there are two species, and that B. densa should not be merged in B. imbricata, which is most probably the form that I have geen. c3 384 MR. HANCOCK ON THE ANATOMY OF THE FRESHWATER their arrangement, neither could I determine their exact relation- ship to the tunic—whether they were attached to it by their extremities only, as supposed by Dr. Farre, or connected with it throughout their entire length. Professor Allman appears to be of the latter opinion, and certainly I saw nothing in confirmation of that expressed by Dr. Farre ; though I am not sure that the extremities are not attached to the cell-walls, thus giving to these muscular belts fixed points of action. Howsoever this may be, these parietal muscles undoubtedly have the power of contracting the tunic, and so lessening the space within which the polype is confined, the contained fluid is made to press on the surface of the polype, constraining it to pass upwards, and thus to effect its protrusion much in the same manner as in Plumatella and Fredericella. In these, however, there is some little difficulty, the cells being continuous ; but in Palwdicella, in which they are all separated, this act can be clearly understood. I have certainly observed in Plumatella and Fredericella the appearance of divisons here and there, forming, as it were, the cells into groups or systems, but nothing to warrant the belief that each cell is isolated. It might, therefore, be thought that protrusion of a few of the polypes would necessitate that of the others, or at least would cause an imconvenient pressure on the other members belonging to the same group. It is difficult to arrive at a full explanation of the propulsion of the polype in these cases ; but there can be no doubt that in them, as in other Bryozoa, the contraction of the tunic is the sole agent. Dr. Farre believed that the act of protrusion did not so much depend on the contraction of the tunic, as on the straightening of the alimentary canal, which, in the marine spe- cies and in Paludicella is doubled upon itself when the polype is retracted. But in Plumatella, Predericella, and Alcyonella, it is always straight ; in these genera, therefore, protrusion cannot in the least be assisted by the alimentary canal. Professor All- man has referred to this fact to prove the error of Dr. Farre’s opinion ; and, indeed, if it be allowed, and I suppose it must, that the pressure of the fluid maintains the protruded animal in its position, it is more than probable that the same power would be BRYOZOA, WITH DESCRIPTIONS OF NEW SPECIES. 389 sufficient to perform the act of protrusion. From the movements of the alimentary canal, it is pretty evident that it has the power of straightening itself: but when quite straight, only a portion of the tentacles would be protruded beyond the cell; and here they would remain, for it is very clear that whether straight or bent, the alimentary canal will displace the same quantity of fluid, and that there would be no increase of pressure to force the ani- mal upwards. It is, at the moment, when the alimentary canal is being straightened that the parietal muscles come into play, and compel the animal to rise above the cell : these acts are perfectly simultaneous. The protrusion, therefore, of the polype, with a bent cesophagus and intestine is effected in the same manner as that in which these organs are straight; only that in the former it is accompanied with the straightening of the alimentary canal. The sixth and last set of muscles to be described, is for the purpose of preventing the entire eversion of the tentacular sheath. This set, Pl. V. figs. 1 7, r & 2 q, q, is the homologue of the strong radiating muscles in Plumatella and Fredericella ; but the fibres are much less numerous. In Paludicella they are only four in number, and take their origin from the inner surface of the cell, two in front immediately below where the tube joins the cell, and two behind in a line with the upper wall of the tube; hence the fibres are placed in front of, and behind the polype, and are inserted into opposite points of the tentacular sheath a little way below its summit, having on each side of them the two bundles of the tube-retractors. In the retracted state of the polype, these fibres are seen passing downwards towards their insertion. When the polype is protruded, these muscles cause the sheath to double upon itself, and thus retain a portion of it within the tube ; but not to the same extent as in Plumatella and Fredericella. It has already been pointed out that in these genera, this set of muscles compensates for the want of the circle of setee which surmounts the orifice in the marine species. In Paludicella, however, we have already seen that there is a wide, delicate, membranous cup, which rises from the inner surface of the tube, a little within the orifice. This cup is undoubtedly the homologue of the circle of sete alluded to, but ina very rudimentary state, and probably of 386 MR. HANCOCK ON THE ANATOMY OF THE FRESHWATER little or on functional utility: consequently, these muscles are still present, though, as might be expected, not so fully developed as in those genera entirely deprived of this appendage. We have now gone through the whole of the muscular appa- ratus for retraction and propulsion, and to verify the use of the various sets of muscles, we must once more observe the animal while issuing from the cell. The first symptom indicative of the polype’s inclination to come forth, is the contraction of the parie~ tal muscles, causing the tunic in certain places to leave the walls of the cell, particularly towards the lower portion; on this the polype commences to move up the cell, and at the same instant the tube-retractors relaxing the inverted lips of the orifice, begin to be evolved, and as the contraction of the parietal muscles goes on, the polype advances upwards, and more and more of the tube is turned out, in the manner of the eversion of the horn of the common snail; at length the membranous cup makes its appear- ance, not doubled upon itself, but in an erect position — the margin first, just as the circle of sete is exserted in Bowerbankia. The cup at first is laterally compressed, having been packed longitudinally in the axis of the tube: the tips of the tentacles now emerge through the centre of this cup, and as they pass upwards, pressed together in a line side by side, its lateral folds give way, and by the time that the tentacular disc has reached the mouth of the cell, the cup is perfectly expanded. The muscles preventing the entire eversion of the tentacular sheath, may now be seen in action near the upper extremity of the tube, holding back the membranous sheath, and causing it to roll upon itself. The polype is now fairly above the mouth of the cell, and as the tentacles expand it has attained its greatest elevation; the cilia then commence to play, and all kinds of particles are hurried towards the mouth. The retraction of the polype is instantaneous, so rapid indeed, that it is quite impossible to follow with the eye, the actions of the muscles ;—such is the velocity with which this feat is per- formed, that from complete protrusion to invagination, nothing can be perceived but the settling of the polype upwards, after having apparently been dragged too far down the cell. It is not BRYOZOA, WITH DESCRIPTIONS OF NEW SPECIES. 387 difficult however to understand how the act of retraction is accomplished ; the operation of the muscles will be reversed. First the parietal muscles must relax, allowing the tunic to assume its place close to the cell-walls ; at the same instant the polype retractors will contract, and as the animal sinks into the cell, the superior tube-retractors will also contract; next the inferior tube-retractors will come into play; and, finally, after retraction is complete, the sphincters will close the orifice. On comparing the muscular system of the freshwater Bryozoa with that of the marine forms, a great similarity is observed ; some interesting modifications however are deserving of notice. The most remarkable of these are found in connection with the orifice. In Plumatella and Fredericella there is no tubular in- version on the retreat of the animal ; the tunic is certainly doubled upon itself for a short distance within the orifice, but it remains permanently so. Paludicella, on the contrary, has the walls of the tubular orifice invaginated to a considerable extent when the polype is retracted, and when protruded nearly the whole is evolved. But Bowerbankia and other marine forms differ from the freshwater species, in having the mouth of the cell completely unrolled when the polype is protruded, the same having been invaginated to a great extent when it was retracted. Thus in the first and last modifications we see the extremes of variation, and consequently the most extensive alterations in the muscular arrangements of these parts. Paludicella being in a middle state has the muscular apparatus to some extent of both ; and in this respect connects the freshwater with the marine forms. The tube-retractors are wanting in Plumatella and Fredericella, and are present in Paludicella and in all the marine species, being most developed in the latter. Neither in these nor in Paludicella, however, is there anything like the small radiating muscles near the orifice in Plumatella and Fredericella; and the marine species, too, are destitute of the large radiating muscles in connexion with the tentacular sheath. These, though present, we have seen are less developed in Paludicella than in Plumatella and Fredericella, the former resembling Bowerbankia, in having a cup at the mouth of the cell. The polype-retractors are very 388 MR. HANCOCK ON THE ANATOMY OF THE FRESHWATER similar in all the Bryozoa, only those at the inferior extremity of the stomach in the marine species appear deficient in the freshwater forms. They all have, however, one or more appen- dages to this part, but these we shall afterwards see are most probably connected with the reproductive system. The parietal and sphincter muscles are common to both Paludicella and the marine forms. On the whole, then, in the muscular system as well as in the digestive apparatus, Paludicella shows a close re- lationship to Bowerbankia and its congeners ; and is, in fact, an intermediate link between them and the other freshwater Lryozoa. Hven the minute structure of the muscles themselves would seem to confirm this. In all, they are composed of trans- parent, linear fibres separated from each other and apparently homogeneous. When broken they become irregularly nodulous; but I have not succeeded in detecting transverse strie observed. by Professor Allman, probably from having used insufficient mag- nifying powers. The small knot-like swelling, so remarkable in the centre of the fibre of the marine species, is not to be found in either Plumatella or Fredericella; in Paludicella, however, I have observed it in the parietal, but in no other muscles. Reproductive System.—In the freshwater, as in the marine Bryozoa, there are two methods of reproduction,—one by buds, the other by eggs. The buds always germinate from the same part of the cell, hence the definite form of the polypidom. In Fredericella the germ is found in connection with the inner sur- face of the tunic, not far below the orifice of the cell on its lower side. As the bud enlarges the wall bulges, showing externally the appearance of a new shoot. At first the bud, Pl. III. fig. 3a, is small and oval, and is attached for nearly its whole length; it, fig. 2 0, soon becomes irregular in form, with the upper portion broad and somowhat bifid, the lower extremity prolonged: the upper portion then gradually exhibits a circle of short rudimen- tary tentacles. fig. 47,; and the lower end is seen to be divided longitudinally into esophagus and intestine, fig. 5 6, d, continu- ous at their lower extremities, which still elongating, form the stomach, figs. 4m & 5c. ‘To this is seen an appended filament binding it below to the wall of the cell. Imbedded in this BRYOZOA, WITH DESCRIPTIONS OF NEW SPECIES. 389 filament there is a large, distinct globule with nucleus and nu- cleolus : this we shall afterwards learn is the incipient ovum, figs 40 & 5 e, lying in the ovary. The polype-retractors, figs. 2q&4n, now make their appearance, passing from the tenta- cular base to the side of the cell formed apparently out of the lower portion of the original attachment of the bud ; the upper portion of this attachment dilating, becomes the tentacular sheath, fig. 2 p, into which the tentacles are gradually insinuated as they are developed. The polype being now, as it were, sketched out within the cell of the parent, its own chamber rapidly forms, and in the course of a day or two, the muscles in connexion with the orifice being added, the fresh-born member of the community bursts from the extremity of its cell, and is ready to take upon itself the work of its own maintenance. The development of the bud in Plwmatella differs in no re- spect from that of Fredericella ; and in Paludicella there is no very important deviation, except at the commencement of the process. In this the first apparent step in the growth of a new polype, is the preparation of a distinct cell for its reception. If the top of the last-formed cell be carefully examined, even before its tenant is fully grown, the lining membrane may be seen ter- minating in a blind sac, Pl. V. fig. 4 0’, a little below the extre- mity. Within this extremity will also be observed a membranous sac, 7; at first the base of this sac is moulded on the convex blind termination of the lining of the old cell. The convexity however soon flattens, and the sac rapidly increases in size, the external horny covering becoming, at the same time, elongated and attenuated. After awhile, an oval, somewhat opake body, the new bud, fig. 5 m, germinates from the inner surface of the - lining membrane, 7. This body is attached by its side to the front wall of the cell, and resembles the young bud in Prederi- cella. A long and very delicate membranous sac, fig. 6 d, after- wards the tentacular sheath, is now observed to be forming in contact with and above the oval bud; whilst from the lower extremity, filaments, e, are seen to be produced which form the polype-retractors. From the upper end of the bud, the tentacles, fig. 4d, soon make their appearance within the lower part of 390 MR. HANCOCK ON THE ANATOMY OF THE FRESHWATER the membranous sheath, ¢ ; at first very short, no more than the scalloped margin of the cup-formed disc ; but rapidly lengthen- ing, fig. 5 a, they soon advance more than half way up the sheath. The polype-retractors, figs. 4 7 & 5 g, by this time are considerably developed, and the retractors, k, 2, of the tube are distinctly visible ; the tube, fig. 57, now begins to bulge, and the inverted margins of the orifice are seen within, united to the upper end of the tentacular sheath: the parietal muscles, h, also make their appearance at this time, and the stomach, ¢, intestine, d, esophagus, b, and tentacles having all assumed their proper forms, the young animal is ready for protrusion. The buds of Paludicella, however, do not all originate from the extremity of the old cell ; some sprout from the side, and then a slight swell- ing takes place on the inner surface of the tunic. The horny sheath soon afterwards begins to bulge, and an external cell being formed with its lining membrane, an oval bud makes its appearance, and development goes on as just described. Tt has been long known that these animals propagate by eggs as well as buds. Raspail appears to have described the anatomy of the egg and the hatching of it, and the subsequent growth of the young polype has been minutely investigated by Sir J. G. Dalyell. But the generative organ remained unrecognized until it was pointed out by Professor Allman. The appendage to the lower extremity of the stomach, considered by Trembley to be muscular, Professor Allman believes to be an ovary: that it is so there can be no doubt, as eggs may occasionally be seen in connexion with it. Appendages of this kind exist in Alcyonella, Plumatella, Fredericella, and Paludicella, and will probably be found in all Ascidian polypes. In Plumatella and Fredericella there are however three of these appendages or filaments, Pl. IV., figs. 4 f, d, d, & 5 «, e’, h, h, which are all attached to the lowest part of the stomach, and passing down have their other ends at- tached to the wall of the cell, not far from the insertion of the polype-retractors. It is difficult to say whether all three are con- nected with the generative function, or whether some of them are not muscles for the retraction of the stomach. A bundle of such retractors has been described by Dr. Farre, in the marine species BRYOZOA, WITH DESCRIPTIONS OF NEW SPECIES. 391 attaching the inferior end of the stomach to the base of the cell ; but one of them is generally thicker than the rest, and may pro. bably be connected with the reproductive system. Paludicella has two such filaments; one, Pl. V., figs. 1 & 7 7, g, passing in the usual manner from the lower end of the stomach ; the other, m, d, from the upper. These two filaments are inserted upon the posterior wall of the cell, one a considerable way above the other. When the polype is retracted, these insertions are found to be a little: above the gastric attachments, and the filaments, fig. 27k, doubled upon themselves. These are thick, cylindrical, and ap- parently tubular, and do not at all resemble muscles, and indeed, from the relative position of their attachments, they seem ill adapted for retraction. In Plumatella and Fredericella, one, PI. IV., figs.4d,d, &5e, é, of the filaments is generally stouter than the other two, and this has frequently an egg, e, f, attached to it. When the ovum is much developed, it is difficult to make out its relationship to the filament or ovary; but when quite young, it has all the appearance of originating from the interior. On one occasion, I observed two egos in connexion with the ovary, one almost mature, the other only forming. The former, fig. 5 7, was attached rather below the middle of the generative organ. When the polype was pro- truded, this organ dragged forward the upper end of the egg; the other end of it was then seen to be attached to the wall of the cell by the continuation of the filamentous ovary e’. A little below the egg there was a slight oval swelling, in the interior of which was seen a nucleated cell, g, undoubtedly an ovum in a very early stage of development, and apparently in the interior of the ovary.* In Fredericelia, a similar nucleated cell, Pl. III., figs. 4.0 & 5e, has been observed in the appendage to the sto- mach, while the polype was yet in a very rudimentary state as exhibited in the bud before alluded to. In this genus, I have likewise seen the ovum in a considerably advanced state, in which also its relationship to the ovary could not be mistaken. In this instance, the lower portion of the generative organ had dilated -* T have also seen a similar nucleated cell in the enlarged filament from the lower end of the stomach of Bowerbankia. D3 392 MR. HANCOCK ON THE ANATOMY OF THE FRESHWATER into a sort of capsule, within which the egg, Pl. TIL, fig. 6 a and PL. IV., fig. 4 e was enveloped. The portion of the ovary, Pl. IIL, fig. 6 ¢, below it was short and thick, having the appearance of a pedicle, by which the egg was fixed to the side of the cell; above the capsule, the ovary, c’, was much thinner, contracting suddenly upwards. This would seem to demonstrate that the egg is developed in the interior of the ovary. T have also seen what I take to be the ovum of Paludicella, but as it differs considerably from the egg of the other freshwater Bryozoa, we must not pronounce with certainty. This supposed egg was first observed in the cell of the dead polype; two or three occurred ; they were attached to the upper portion of the interior of the cell. Afterwards one, Pl. V. fig. 7 e, was found in connexion with the living animal, and in this case was fixed by a delicate membranous sac, f, to the side of the cell, at the point of attachment of the filament coming from the upper end of the stomach, the base of the filament being apparently sur- rounded by the sac. This filament then, in Palucidella, is pro- bably an ovary; and if so, the egg must pass in a very early stage from it, into the membranous sac at its base, and there be matured. And, judging from analogy, the other filament is also probably connected with generation. In Plumatella and Fredericella however there can be no doubt of the ovarian character of one of the filaments attached to the stomach ; but the nature of the other two, Pl. IV., figs. 4 f& 5 h, h, is not so easily determined. They certainly do not look altogether unlike muscular fibres; but from their attachments close to that of the ovary, and from their resemblance to it, they are most probably connected with the generative function. It may be that each filament is a separate ovary, and that one or two of them is the male organ. These polypes are most probably hermaphrodites—at least, in all the specimens of Plwmatella All- mani that I have examined, there was scarcely a cell that did not contain one egg or more. It may therefore be presumed that each individual is provided with male and female organs. Dr. Farre discovered moving bodies in the visceral cavity of Valkeria and some other of the marine forms, and described them as re- BRYOZOA, WITH DESCRIPTIONS OF NEW SPECIES. 393 sembling Oercarie. I have detected similar bodies in Bower- bankia with large rounded heads and long tails ; they were very numerous, and moved rapidly about in the interior of the cell in the manner of tadpoles, that is, with a lateral undulating motion, and are assuredly Spermatozoa. A testis may then be expected to exist in the freshwater Bryozoa coextensively developed with the ovary, and from analogy to be associated with it. It is not unlikely therefore that these additional filaments from the sto- mach, may be really the male organ. Hach polype does not appear to produce more than two or three eggs; in Plumatella frequently only one. In P. Allmani they, Pl. IV., fig. 5 f are considerably depressed, of an oval form, sometimes very long with the sides almost parallel; they are very large, being sometimes almost as wide as the diameter of the cell, within which they are placed lengthwise; the margins are reti- culated, yellow, pellucid, thin, and sharp, forming a well-defined rim about the central portion, which is opake and black; the covering is smooth, tough, and membranous. In /redericella, the ego is broader and more regularly oval, ofa brownish colour with the margin narrow, plain and of a paler hue. The egg, Pl. V., fig. 7 ¢, of Paludicella, if egg it be, differs considerably from the above. It is of an irregular oval shape, about half as wide as the cell, colourless and pellucid; the surface is marked with a few indistinct, irregular, nucleated cells; one larger and much more conspicuous than the rest, with a distinct round nucleus in the centre, is always to be seen on one side. The circumference of the egg exhibits a double margin indicating an enveloping shield. The great size of the egg forbids the possibility of its escape without the destruction of the polype.* In Plumatella, the ova * The polype of the marine species must also perish on the escape of the gemmule. On examining some specimens of Bowerbankia in August, almost every cell was found to contain a large, round, opake, bright yellow corpuscle. These corpuscles were, for the most part, in the lower portion of the cells ; some however were half-way up, and others not far from the top: those lowest down were the smallest, and as they approached the top they increased in size until their diameter was nearly equal to that of the cell. As long as the corpuscle remained near the lower extremity of the cell, the polype was alive and active ; but was invariably dead when it had advanced far upwards. At first the corpuscle does not appear to have any envelope, but as it increases in size a distinct margin makes its appearance, which afterwards becoming wider and perfectly transparent, the corpuscle can be seen rotating within, by the aid of 394 MR. HANCOCK ON THE ANATOMY OF THE FRESHWATER or maturity become attached to that side of the cell which is con= nected with the substance sustaining the polypidom. And here they remain fixed, indicating the track of the various branches of the Bryozoon long after its decay and disappearance in autumn. The free branches however must scatter their eggs. Most likely in Fredericella, too, they are dispersed, and borne away by the currents on the destruction of the: polypidom, which is very freely branched ; and in no instance have I seen its eggs left adhering to the surface of its attachment. Having now gone through the details of the anatomy and de- velopment of the freshwater Bryozoa so far as I have been able to study them during a very short but laborious investigation of the subject, it is quite evident that these animals are as highly organized as the marine Ascidian polypes. Plumatella and Fre- dericella certainly show some interesting deviations from that type; but in Paludicella, we perceive an almost complete resem- blance to it; proving the close affinity that exists, and the pro- priety of uniting the whole into one group. The approximation of this genus to the marine forms is evinced not only by the mus- cular system, but likewise by the digestive apparatus ; and by the bright, pellucid, horny character of the external polypidom. Tt is also equally evident that the organization of this group is very much above that of the typical Radiata. This Professor Allman has already clearly demonstrated; and yet perhaps we ought to hesitate before removing the Bryozoa into the subking- dom Mollusca, as proposed by this naturalist. The immediate relationship of these animals to the Ascidic is too obvious to be called in question,—a relationship which has long been acknowledged, though the homology of the parts does not appear to be correctly understood ; at least it will bear ano- the long cilia that clothe its surface. While watching one in this state under the microscope, I observed it gradully elongate itself and pass with a slow gliding motion to the top of the cell; then forcing its way through the previously closed orifice, and passing into the surrounding fluid, commenced to rotate with extra- ordinary velocity: in an instant after this its enveloping membrane was torn open and cast aside, and the little being, a broadly ovate gemmule, dashed at once beyond the field of view. It afterwards kept moving about in various directions, and evinced great activity, cilia densely clothing it from end to end. The cell, after the escape of the gemmule, continued gaping; and the polype, . which before was indistinctly visible, had now quite disappeared, nothing but alight traces of the retractor muscles remaining. BRYOZOA, WITH DESCRIPTIONS OF NEW SPECIES. 395 ther interpretation, which I am inclined to look upon as the true one. Dr. Farre observes in his paper, that “in Zunicata the tentacles are reduced to mere rudiments at the entrance of the respiratory sac, and the cilia are distributed over the surface of this cavity, which is in proportion magnified, and is analogous to the pharynx of Ciliobrachiata. The more immediate entrance to the alimentary canal, thence called mouth, being situated at the bottom of this sac, corresponds with the part that I have called cardia.” This view of the relationship of the parts has, with some modi- fications, been generally followed by subsequent writers. In all the Ascidians however, there is a well-defined cesophagus, which in Clavelina is frequently of great length. Why then should the entrance to it be considered to correspond to the cardia in Brgozoa? These, as well as the Ascidiw, have a well-marked stomach with cardiac and pyloric orifices; in both, too, there is a distinct esophagus; then should not the orifice leading to it be assumed to be the mouth, or analogous to the mouth in both? In the polype a series of respiratory tentacles, in the Ascidie the branchial sac, surrounds this mouth; should not these then - be considered homologous? The affirmative of this would ap- pear to be the natural inference in the first instance. But we are referred to the tentacular filaments, at the entrance of the respiratory sac, as the true representatives of the tentacles of the polype. With the view to ascertain how far this is correct, I examined, with much care, Ascidia sordida and Molgula arenosa, and found that these tentacular filaments are not anatomically connected with the branchial sac, but are developments from the tunic. The sac terminates a little way below these filaments, and they fringe the inner circumference of the belt of sphincter muscles which guard the respiratory orifice. These tentacular filaments, then, originating in the tunic, cannot possibly be the homologue of the tentacles of the polype, as these undoubtedly belong to the alimentary canal ; but are in fact a new develop- ment in connection with the sphincter of the tunic, and share its function. The tentacles then of the polype and the branchial sac of the Ascidian would appear to be homologous ;—unless 396 MR, HANCOCK ON THE ANATOMY OF THE FRESHWATER indeed the tentacles of the one have died out, and the branchial sac of the other is altogether a new development, which is not by any means likely. In confirmation that the former is the fact, we have only to look at the growing bud of the polype. which so closely resembles an Ascidian, particularly when young, that it might at first sight be taken to be one. The tentacles at this time, all lying parallel to each other within the membranous sheath, have quite the ap- pearance of a branchial sac; and when we take in connexion with it the alimentary canal, the resemblance is almost complete. Indeed, all that is wanting to turn the polype into an Ascidian, so far as the alimentary and respiratory organs are concerned, is the union of the tentacles by a vascular membrane. And we have already seen that such an union has commenced in Frede- ricella, Plumatella, and Alcyonella. We have seen that in all these genera the tentacles are united at the base by a delicate membrane; and in the former this membrane is so extensive as to suggest the idea of a rudimentary form of the branchial sac of the Z'unicata. Taking this view of the homology of the parts, the longitudinal lamin in the interior of the branchial sac of the Ascidic will represent the tentacles of the Bryozoa; and the membrane at the base of the tentacles, being external, corresponds exactly in posi- tion to the vascular membrane of the Ascidicw, which is also ex- ternal to the lamin. ‘The position of the nervous ganglion in the two forms might at first sight appear to favour the contrary opinion; but, on closer inquiry, it is evident that the ganglion of the Bryozoa is not homologous with that of the Ascidiew: in the former it is a cerebral ganglion resting on the esophagis imme- diately behind the mouth; in the latter, if it has relationship to any of the nervous centres of the JJollusca, it is apparently ana- logous to the branchial ganglion of the Lamellibranchiata; but its position in the mantle is anomalous. We thus see how very intimate is the connexion between the Bryozoa and the Ascidie; and as the latter are generally sup- posed to be as closely connected with the Lamellibranchiata, no great distance would appear to divide them from the former. BRYOZOA, WITH DESCRIPTIONS OF NEW SPECIES. 397 They are not, however, so closely related as might be supposed. At first sight, an Ascidian undoubtedly seems very closely to ap- proximate to a bivalve, shell; but this similarity, on careful investigation, would appear to be more that of analogy than ho» mology—a mere resemblance rather than a true relationship. The branchial sac of the Ascidian is frequently assumed to be the same organ as the gill-plates of the Lamellibranchiata some- what modified ;—in function there is no difference; but anato- mically they are distinct. The former is a development from the alimentary canal ; the latter, according to Professor Owen, “ are essentially internal folds of the pallial membrane.” The breath- ing organs then of these animals are not homologous. To turn therefore an Ascidian into a Lamellibranchiate mollusk, a new branchial organ must be developed. The vascular system, too, if not anatomically different in the Ascidian, is in a remarkable manner functionally so. In this the heart is at once systemic and pulmonic. And it is worthy of remark, that thus, on the first appearance of the vascular apparatus in this type of animals, it should shadow forth the peculiarities of both the molluscan and the piscine heart; and this, too, in connexion with a pha- ryngeal gill. The test or outer sac, and the inner sac or tunic of the Zunicata are not related to each other in the same manner as the shell and mantle of the mollusk. In this the shell is extra-vascular, and is secreted by the mantle; in the former the test is vascular, and its growth is therefore not dependent on that of the inner sac or tunic. The reproductive system of the Lamellibranchiata is likewise very different from that of the 7’u- nicata. In these it is formed on the type of the Radiata ; ano- ther and very striking proof of the relationship that exists be- tween the former and the Bryozoa. These, and other points of difference, led Professor Milne-Edwards, in his valuable memoir on the ‘ Ascidiens Composées,’ to propose the separation of the Tunicata from the JZollusca, and the formation of them into a distinct group to be placed between the bivalves and the polypes. We then cannot find a passage from the Bryozoa through the Ascidice into the Lamellibranchiata. There are however two distinct branches of the Ascidian polypes,—one with the tentacles 2 398 MR. HANCOCK ON THE ANATOMY OF THE FRESHWATER arranged in a circle about the mouth,—the other having them supported on two lateral oral arms. The former of these branches passes into the Ascidian,—the latter, I shall endeavour to show is connected with the Brachiopoda. This connexion is at once suggested by the resemblance that exists between the oral arms of Plumatella and Alcyonella and the characteristic brachial organs in the Brachiopoda, particu- larly of those in Lingula. In both the Brachiopoda and the Bryozoa, the arms rise from the sides of the mouth in the same manner, the bases of the arms being confluent; and the tentacles or cirrhi forming a continuous series. In both the arms are hollow, and the tentacles and cirrhi are tough and non-contractile ; and in both they are prehensile organs after the same fashion. The digestive organs of both are very similar; and the whole of the Brachiopoda are fixed, and so are the Bryozoa, with but one exception. But what is still more remarkable, the muscular systems of both are arranged much in the same manner, particularly as re- spects Zerebratula and Paludicella with most of its marine con- geners. In Yerebratula, as the animal is fixed within the shell, of course there can be nothing resembling the polype retractors ; but the shell muscles of Zerebratula will be found to work exactly on the same principle as those provided to draw in the margins of the cell-orifice in Paludicella and Bowerbankia, and called by Dr. Farre, opercular muscles. There are four sets of muscles in connexion with the shell in Terebratula chilensis as dissected by Owen, two from each valve ; and they all pass diagonally downwards, and with one exception go to be inserted in the pedicle; so that when they contract the valves will be closed. These muscles then have in fact their origin in the pedicle, as stated by Owen, and acting from thence upon the moveable points of their insertions, operate precisely in the same way as the tube-retractors of the polypes last men- tioned do on the lips of the orifice. The action is the same in both; and were the cell-walls of Bowerbankia, for instance, cal- cified and divided longitudinally into two portions or valves, they would be made to close just as the valves do in Zerebratula. BRYOZOA, WITH DESCRIPTIONS OF NEW SPECIES. 399 The set of muscles alluded to, as not passing into the pedicle comes from the perforate valve, and, inclining downwards, is attached by the other end, to the base of the imperforate valve binding the parts of the hinge-joint together—a substitute in fact, for a ligament. In some species, this set assumes in part, the function of an adductor muscle. We have then evidently some reason for supposing that the Brachiopoda, as well as the Ascidie, are related to the Bryozoa; and it is in this way that these latter are connected with the Za- mellibranchiata. After a careful examination of the Brachiopoda, it is impossible to doubt the connexion that exists between the two great divisions of the testaceous Acephala. Indeed this is evident, whether we look to the digestive organs, the vascular system, or to the reproductive apparatus. It is in these animals, too, that the respiratory organ is first found in connexion with the mantle, in Z'erebratula, quite rudimentary, in Lingula, to some extent specialized. On comparing Anomia with Orbicula, this relationship is best seen. In both, the mantle is completely separated, and in both it is connected with the ovary ; the large oral palpi of the one form the homologue of the branchial organs of the other; and we see this relationship in the deficiency of pedal organ in Anomia, and in the extensive union that still subsists between its breathing apparatus and the mantle: the perforation of the under-valve of both is also remarkable; but not more so than that the great muscle of both should be divided, part forming the adductor, part the adhesive disc. We have now endeavoured to trace the affinities of both branches of Bryozoa ; one appears to pass at once into the As- cidice, which, how closely soever related analogically to the Lamelli- branchiata, are nevertheless removed far from them, by the nature of their vascular, respiratory, and re-productiye systems, In the Mollusca, the heart is always systemic, and the gill is universally an appendage to the mantle. In the Asczdie, the heart is as much pulmonic as systemic, and the breathing apparatus is a de- velopment from the alimentary canal—is in fact pharyngeal. In these respects the Ascidian deviates from the Molluscan type, and approximates to that of the lower Vertebrata,—the fishes, in ES 400 MR. HANCOCK ON THE ANATOMY OF THE FRESHWATER which the heart is pulmonic, and the breathing organ pharyngeal. The reality of this relationship is revealed by the anatomy of the Lancelet, so ably described by Professor John Goodsir, who has pointed out the resemblance of its respiratory system to that of the Z’unicata. Indeed the branchial sac and vascular apparatus of this curious fish almost completely resemble those organs in the Ascidian. The other branch of the Bryozoa, comprising those with oral arms, passes into the Brachiopoda ; or, at least, this is rendered more than probable by the resemblance of the brachial organs of the latter to the arms of the former, and by the similarity of the muscular arrangement. Thus the Bryozoa become related to the Lamellibranchiata, which are apparently closely related to the Brachiopoda. We may conclude, then, if we have arrived at a right understanding of the affinities of these animals, that both the Mollusca and Vertebrata are connected with the Bryozoa. It would be well, therefore, to pause before including the Bryozoa in the Mollusca, and consider the propriety of uniting the former with the Zunicata, and perhaps with some of the higher forms of Rotifera, into a group to be placed at the head of the Radiata.

Polypidom adhering throughout, coriaceous, pellucid, of a pale watery green colour, irregularly but not much branched, seldom extending more than half an inch; branches composed of a series of large, eonical cells tapering upwards towards the aperture, sometimes considerably and rather suddenly dilated at the base ; resembling in form some of the Ascidians ; the upper portion of the cell almost colourless and freckled with minute opake white spots, most crowded towards the orifice. ‘Tentacles white, not more than sixty in number; membrane, at their origin, rather wide, scalloped, the points of the scallop extending for some dis- tance up the back of the tentacles, in the form of broadish lamine arched outwards. Cisophagus and stomach appearing through BRYOZOA, WITH DESCRIPTIONS OF NEW SPECIES. 401 the transparent walls of the cell, of a pale yellow colour. Egg perfectly black, large, broad, and oval. Upwards of a dozen specimens of this fine species occurred in Bromley Lough, adhering to the underside of stones ; it was like- wise taken in Crag Lough. None of the individuals much exceeded in size, that represented in the figure, nor did they vary in any remarkable manner either in form or colour. It is not, however, without hesitation that I have ventured to characterize this as a new species, as Professor Allman informs me that it may perhaps turn out to be P. repens ; but that form is stated to be large and of luxuriant growth, and to have the polypidom tubular with the cells dilated at the orifice—characters which do not at all agree with P. punctata. Indeed it can scarcely be considered a true Plumatella. P. Alimani. PI. VI. figs. 3, 4, & 5, and Pl. IV. figs. 2 & 3. Polypidom attached to the underside of stones, adhering throughout, membranous, opake, yellowish brown, slightly branched, extending in patches sometimes three or four inches wide, the patches being made up of several polypidoms; the branches composed apparently of a series of tubular cells, tapering to their origin, and attached for more than half their length ; the enlarged extremity being free and bending upwards, inclines a little to one side, and is occasionally bifid, forming two cells ; an obtuse ridge or keel extends the entire length of the cell, increasing imperceptibly in thickness upwards; orifice somewhat constricted, the walls immediately below being pellucid, and suddenly dilating become abruptly opake, and thickly covered for some distance downwards, with agglutinated sand. Tentacles forty-two in number, slightly tinged with yellow, the colour best seen when they are formed into a compact bundle ; membrane at their base distinct, scalloped, the points being prolonged a little up the tentacles. Egg black, long, oval ; sides nearly parallel ; margins pellucid, yellow, sharp, broad, and reticulated. This species was procured rather abundantly in Bromley Lough, and does not appear to vary much. At first sight large patches of it have the appearance of being formed of a single polypidom ; 402 MR. HANCOCK ON THE ANATOMY OF THE FRESHWATER but, on close examination, are found to be composed of many, and rarely to number more than six or eight cells in each. The commencement of each polypidom has the black envelope of the originating egg adherent. Two or three specimens of a more branched form of carinated Plumatelia, were taken in Bromley Lough, which may probably prove a distinct species ; more individuals, however, are necessary before it can be characterized. Paludicella procumbens. Pl. VI. figs. 1 & 2, and Pl. V. Polypidom membranous, subhorny, pellucid, smooth and glossy, ofa brownish horn-colour, much and irregularly branched, forming large patches on the underside of stones, for the most part adhering, with rather numerous, short, free, almost simple branches ; the branches composed of a single series of narrow cells arranged longitudinally, contracting towards the base and widening upwards ; aperture lateral, near to the upper extremity of the cell, forming a rather long and somewhat constricted tube inclining upwards ; margin entire, surmounted by a widish, deli- cate, hyaline, membranous cup. ‘Tentacles sixteen in number, arranged in a complete circle, and when spread out forming a very exact inverted cone. | This, the second species of the genus, resembles very closely P. articulata of Allman, but that form appears to have about twenty-six tentacles, and is likewise more densely and luxuriantly branched ; the cells, too, are larger and of a different colour. The P. procumbens occurred in both Bromley and Crag Loughs, but most abundantly in the latter, where it spreads over the under surface of stones in patches of 5 or 6 inches diameter.

By Aupany Hancock, Esq. [Read Wednesday, December 12th, 1849.] On visiting the Northumberland lakes, last August, for the purpose of prosecuting my inquiries respecting the freshwater Ascidian Polypes, I took a very beautiful Hydra, abundantly in Bromley Lough. On a subsequent occasion, numerous specimens of the same species were also obtained in Crag Lough. They were found associated with the various Bryozoa that inhabit these waters, adhering to the under side of stones which lie scattered by their margins, and in situations where there was neither mud nor vegetation. From the peculiar character of the locality, so different from that of the usual habitat of the Hydro, I was in- duced to examine the specimens with great care, and find that 406 MR. HANCOCK ON A SPECIES OF HYDRA, they do not exactly agree with any of the known forms, though they come very near to H. fusca, of which they may probably prove to be a variety. On removing from the water, a stone to which these Hydre are attached, they appear as irregular, minute depressed globules of gelatine, of a pale red flesh-colour, dispersed over the surface, sometimes in great numbers on one stone, but never crowded on each other. When placed in a bottle of water, they soon become fixed to its sides, and spreading out their tentacles, display them- seves to great advantage. They are now seen to be very variable in form, Pl. VII. figs. 3, 4,—or rather that they have great com- mand over it, contracting themselves until they are almost globu- lar or vase-like, with the tentacles very short and swelled out in the centre ; then extending themselves, they become linear, much attenuated, and frequently half an inch long,—the tentacles, fig. 5, being very delicate, and tapering imperceptibly towards the ex- tremity, which is enlarged and rounded, forming a nodule or bulb of no great size, but quite visible to the naked eye. The polype, however, is usually much less extended, and is generally a little bulged in the centre ; the tentacles are then somewhat longer than the body, but are shorter than it when the animal is fully stretched out. There are usually six tentacles, occasionally five, rarely seven ; they are white, never coloured in the centre like the body, which, as already stated, is a red flesh-colour ; it is also sometimes yellowish. The colouring, which is apparently much affected by exposure to light, depends on the granules that line the internal or digestive cavity, and is most intense near the mouth. When in their native haunts, attached to the under side of stones, the Zydrc must be nearly in total darkness; but on being placed in a bottle, they become exposed to the solar rays, and in the course of a few days, are almost completely bleached. Sup- posing that this loss of colour was occasioned by the want of food, the specimens were supplied with animalcules ; but their original hue was not in the least restored. During the first week or ten days, the captives added greatly to their numbers, by gemmation, the buds sprouting from the FOUND IN THE NORTHUMBERLAND LAKES. 407 lower portion of the body,—rarely more than one at a time. Afterwards the budding was much less frequent ; and in about a month from the time they were taken, most of the specimens had perished. Two or three, figs. 1 & 2, more favourably placed than the rest, continued to live on for some time longer, and thrived well; but they changed considerably in appearance. A short way below the tentacles, two tubercles, a, a, had developed themselves opposite to each other, and were in every respect symmetrical ; and the body was considerably enlarged towards the lower extre- mity. In this state the animal had a pedunculate appearance, and I was quite at a loss to account for the change. These speci-: mens belonged to the first batch procured in Bromley Lough. On visiting the lakes again, however, in September, and getting a fresh supply, nearly all the individuals exhibited the same appearances ; the tubercles being invariably a little below the tentacles, though not always symetrically placed; and occasionally they were three and even four in number: the swelling, too, on the lower part of the body, varied in different specimens. On placing one of them under the miscroscope, the tubercle, Pl. VIII. fig. 5, was found to be vesicular, of a conical form, with the apex obtuse, and to resemble in texture the general surface of the animal: the basal portion contained an opake, rosy, granular body, a, of a glandular appearance, which completely filled the base of the tubercle: the apex, 6, was pellucid, and on being attentively examined, a crowd of very minute moving bodies were observed within it. Whilst watching, with great earnestness, the motion of these mysterious bodies, all of a sudden the apex of the tubercle burst, and a great number of them, cloud-like, rushing into the sur- rounding fluid, dispersed in all directions. The rupture appeared to close again, and the apex was seen to be almost empty ; but fresh bodies making their appearance, the receptacle was soon as full as ever. I have seen the eruption of these corpuscles on several occasions, and have no doubt that it is a natural pheno- menon ;—not resulting from any artificial means,—certainly not from pressure, as the animals were always quite free. On examining these moving bodies, which are exceedingly minute, F3 408 MR. HANCOCK ON A SPECIES OF HYDRA, with 1th of an inch object-glass, they were found to be of an el- liptical form, and to resemble spermatozoa ; tails, however, were not detected, though with a higher power, it is not improbable that they may be found; for I could not satisfy myself of their non- existence. The nature of these tubercles or sacs, is a matter of much in- terest. They were discovered by Ehrenberg, and described by him as the male organ,—the moving bodies being considered sperma- tozoa. Though I have not seen the original memoir on the subject. I think there can be little doubt of the accuracy of this opinion, How else can we account for the constancy of the appearance of these sacs? for their development at the time the eggs are being produced, as we shall afterwards see is the case !—for their being situated always on the same part of the animal ?’—for the con- tained gland-like body, and moving corpuscles ?—for the eruption of these latter bodies, and for their resemblance to spermatozoa. ? Having thus detected what I believed to be the male generative organ, I was anxious to watch the development of the egg, which appears to have been already described more than once; but as it has rarely been observed by British naturalists, I will venture to give my own remarks on the subject. The lower portion of the body, as before stated, is enlarged at the time when the male organ makes its appearance. On examining the enlargement, Pl. VII. figs. 1 & 2 6, 6, carefully, it is found to be usually greater on one side than the other; here it is opake and of a pale rosy hue, notwithstanding that the animal is faded under the effect of light. The opake swelling extends nearly round the body, the margins being generally distinct. This is the nascent ovum, as it appears at first ; it gradually increases in size, Pl. VIII. fir. 1 d, and ultimately becomes very protuberant, bulging the body excessively on one side: the egg, at this time, is confounded with its covering; but it, d, is soon seen as a rounded, somewhat flattened body, contained within a transparent envelope, e, resem- bling the general surface of the body, of which it is apparently a continuation. This envelope, fig. 2 6, 6, shortly opens at the highest point of the swelling, and the egg, a, gradually makes its way through the orifice, which as gradually enlarges until the egg, FOUND IN THE NORTHUMBERLAND LAKES. 409 figs. 3 6, & 4 e, is completely exposed, and rests, as it were within the mouth of a shallow cup, figs. 3 e, e, & 4 g, the contracted enve- lope. The egg remains in this position for a day, and sometimes longer, attached to the body of the parent by a short, thin pedicle, figs. 3d & 4 f; the margins, at first, are generally undulated, as in fig 4 ; afterwards the egg becomes almost completely globular. It is ultimately detached, and soon fixes itself to some foreign body. On watching one individual through the microscope, the egg was observed to separate from the parent, and to move slowly away. No ciliary action could be detected to account for the motion ; but it assuredly passed out of the field of view as often as the instrument was adjusted: in another instance, however, no motion could be observed. The egg, Pl. VII. fig. 6, in the course of an hour or so, became stationary, and several minute globules, a, a, a, which had been noticed sticking to it from the first, Pl. VIII. fig. 3 ¢, c, enlarged, and others made their appearance: they soon assumed the character of delicate cells, Pl. VII. fig. 7, filled with globular bodies, with dark margins. These globules are probably composed of some tenacious mucus with which to glue the ege to any substance on which it may happen to settle. Soon after attachment, these bodies disappear, and the egg, which is now perfectly circular, is seen to be surrounded by a narrow, transparent rim, indicating the presence of a distinct chorion ; the under side of the egg being flattened, the upper side convex, opake, and rosy as at first. I have not been able to determine, with precision, how many eggs are produced by each polype, but certainly no great number, probably not more than three or four, and in some instances per- haps only one. On one occasion, after the egg separated from the animal, the latter gradually dwindled in size, and ultimately disappeared. Most frequently, however, the polype is not mate- rially altered on giving birth to an egg; and occasionally two, Pl. VIII. fig. 1 d, d, are in process of development at the same time, generally from opposite sides, one being more advanced than the other. The male organ is only developed at the time the eges make their appearance. In August, shortly after the polypes were pro- 410 MR. HANCOCK ON A SPECIES OF HYDRA, cured, they multiplied rapidly, as we have seen, by gemmation, and at this period none of the sacs containing spermatozoa were observed. It was not until they had ceased to propagate in this way, some time in September, that the male organ was developed, and it was always visible afterwards, though variable in size. All the individuals apparently produce eggs, and all are alike provided with the spermatic sacs; at least the ovum, in various stages of development, and the male organ are seen at the same time, in most specimens; it isnot uncommon, however, to observe the male organ only, the egg probably having just left the body of the parent, though I do not recollect having seen the egg in process of development in individuals unprovided with the sperm- vesicles. It is worthy of remark, that the buds sprout from the same part of the body in which the eggs are developed; but I have seen nothing to warrant the assertion, that the ova, after impreg- nation, “sometimes are retained, and then grow out like buds.” Indeed it is probable that fecundation does not take place until the egg bursts through the integument, and is attached to the parent only by a delicate pedicle. This would appear more likely than that impregnation should be effected through the skin of the animal. Whilst watching an individual, when the egg was about to separate from the parent, the sperm-vesicle was fre- quently brought, by the contractions of the body, almost in con- tact with the ovum; thus fecundation might very easily be effected, and at a moment, too, when, from analogy, it might be expected to take place: more observations, however, are required to settle this point. T have also observed sperm-vesicles, Pl. VIII. fig. 6, in 7. viridis; in this species, they are much smaller than in the specimens from the Northumberland lakes, and are generally two or three in number, near the anterior extremity of the body, but without symmetrical arrangement. They are irregularly conical, with the base wide, within which there is likewise a distinct glandular body, of a green colour; the moving bodies are very numerous, and occupy, as in the other species, the transparent apex. The sperm vesicles were noticed in H, viridis, after it had ceased to bud, some time early in October. FOUND IN THE NORTHUMBERLAND: LAKES. 41i The tentacles, Pls. VII. & VIIL. figs. 5,7, are of the flesh-coloured species, are very rough and beautiful, exhibiting an imperfect spiral arrangement of the nodular enlargements. There are two kinds of vesicles immersed in the nodules, as have been described in some other species; one being much more numerous and smaller than the other. The former are for touch, the latter for prehension, according to Corda, who appears to have examined these organs with great care, but whose description of one of them is erroneous in several respects: the original memoir, how- ever, I have not seen. Neither have I had an opportunity of consulting Ehrenberg’s account of the minute structure of the tentacles of these animals. The smaller vesicles, Pl. VIII. fig, 7 a, and fig. 8, seem to agree with Corda’s description as‘given in Johnston’s “British Zoophytes ;” they are elliptical, being com- posed of an inner and outer sac, both very delicate, transparent and membranous. These bodies are placed with their long axis perpendicular to the surface of the nodule in which they are im- bedded, and have a non-contractile hair-like process projecting from the external end. The larger vesicles, fig. 7 6, are very complicated, and appear to have been only partially understood by Corda, though he had arrived at a full comprehension of their functions. They are not merely prehensile organs, but are undoubtedly also stinging instruments, as supposed by this naturalist, and are at least twice as large as those for touch: they, fig. 9, are of an ovate form, short and stout, immersed in the substance of the nodule, with the narrow end uppermost, and immediately beneath the surface. At the bottom of the vesicle, which, though perfectly transparent, has rather thick walls, is seen a delicate lining membrane, d, folded down upon itself, having a cup- or saucer-like appearance. This, according to Corda, is “a saucer-like vesicle.” Standing up from the centre of this, is a transparent membranous stalk, c, irregularly bulged a little at the sides, and surmounted by a sharp arrow-like head, 6, with the barbs much depressed. This supporting stalk is described by the naturalist, just quoted, as “a, solid, ovate corpuscle.” But to get a full knowledge of this apparatus, it must be examined when exserted and ready for 412 MR. HANCOCK ON A SPECIES OF HYDRA, action. The saucer-like vesicle is then seen to have disappeared, and the outer vesicle, fig. 10 a, is lined throughout with a delicate membrane, 6; in fact, the lips or margins of the saucer-like vesicle have unrolled themselves, and now form the upper portion of the lining membrane, the saucer itself being the lower portion of it. And, moreover, the lining membrane is continued through the neck of the outer vesicle, and is seen to be prolonged into the stalk, c, supporting the arrow-head ; the barbs, c’, of which, three in number, are now very much elevated, being almost horizontal ; and thus protruded beyond the surface of the tentacle, are ready to lay hold of prey in the manner of a grappling-iron. The animal would appear, however, to have the power of throwing the whole apparatus from the tentacle. Ifa specimen be laid ona piece of glass, and examined through the microscope a number of these organs, with the barbs fully extended, will be seen scattered about like as many minute Florence flasks; the bulbous extremity being elegantly rounded. For the purpose of ascertaining if the animal really possessed this power, a small worm was given toa polype when under the microscope, and carefully watched. The animal was exceedingly cautious in using its tentacles, not applying them in their whole.extent, as might have been expected, but keeping by far the greater portion of these organs perfectly free, and unattached to itsprey. Very few of the arrow-heads were exserted, and, apparently, never till re- quired ; occasionally certain parts of the tentacles were brought into contact with the worm, and then, as it was forcibly drawn further into the mouth, the protruded barbs might be seen sticking in the surface of the struggling victim. At other times, as it rolled about in its vain endeavours to escape, the bulbous extre- mities of several of these formidable weapons were seen pro- truding from the skin, undoubtedly placed there by the pungent embrace of this deadly and determined foe; while others lay scattered about in every direction, as if just cast from the tenta- cles. It is therefore evident that these weapons can be used either as grappling instruments for securing food, or, having been plunged into some living prey, can be left half-buried in the wound. Indeed when the barbs have been once fairly immersed, FOUND IN THE NORTHUMBERLAND LAKES. 413 it is difficult to conceive how they can be withdrawn; and, there- fore, it is probable that the tentacles can only be disengaged by moulting these organs, which seem to be very slightly attached by the neck of the flask-like portion. This, however, may not be the only reason why these weapons are left in the wound. It has been stated that they are stinging as well as captor organs, and if so, may require time to pour the poison into the wounded animal, The deadly fluid is probably contained in the bulbous portion of the instrument, and by the contraction of its walls may be forced through the other extre- mity which is perforated ; at least from the extreme point, a long, delicate filament, fig. 10 d, almost invariably protrudes, resem- bling very closely the appearance of the long process attached to the stinging bodies thrown out of the papille of olis, and from the tentacles of Actinia. But other bodies much more closely resembling the stinging organs of these animals, were found strewed about, associated with the captor organs. These bodies, fig. 11, are minute elliptical sacs, with a long, slender filament from one end, like that just mentioned, from the pointed extremity of the captor organ. The filaments of both these bodies have a double margin, and are apparently tubular. Now it is more than probable that these elliptical sacs are thrown out of the captor organ, and that the filament, so frequently seen issuing from its pointed extremity, belongs to one of them about to be exserted. We thus see that Hydra is provided with a most efficient stinging apparatus, which having penetrated the surface of its prey, remains fixed there, discharging into the wound its poison- bearing filaments. No wonder then that the embrace of these animals should be so deadly to the animalcule that comes within their reach ; and that the worm, so tenacious of life, should fall paralysed from their touch, and die, as we are told, almost without . a struggle. The captor organs of Hydra viridis are exactly similar to thase just described, but are scarcely more than half their size. In this species, too, they are cast from the tentacle. Corda considers the arrow head, and what he calls the ovate 414 MR. HANCOCK ON A SPECIES OF HYDRA, corpuscle, whicn we have seen is the membranous stalk supporting the barbs, to be calcareous. Acetic acid, however, has no effect on these parts ; and they resist nitric acid for some time, but, in the course of an hour or two, almost disappear under the influence of this powerful fluid. Itis therefore evident that neither of these parts is calcareous: the arrow-head and barbs are probably com- posed of horny tissue, or some other substance with which we are unacquainted. It appears that Corda has also determined the existence of an anal outlet at the posterior extremity of the animal. I have likewise seen what I take to be a similar outlet. On examining a specimen in a highly contracted state, and which was about to discharge an egg, a distinct, constricted, linear channel, Pl. VIII. fiz. 4 6, was observed passing from the digestive cavity through the substance of the adhesive disc, apparently about its centre. From this channel issued a long, linear mass c, of excrementitious matter composed of a tenacious mucus, imbedding a granular substance, resembling both in colour and texture that which lined the digestive cavity. The true nature of this outlet is enigmatical, since it is known that the refuse of digestion is discharged by the oral orifice. Professor Owen suggests that “it may give passage to certain execrations of the villous lining membrane of the alimentary canal.” From the facts just mentioned, it would appear that this conjecture is probably correct.

HARDY ON DESCRIPTIONS OF SOME XIX.—Deseriptions of some New British Homopterous Insects. By James Harpy, sq. (Read Thursday, April 4, 1850.] In arranging my collection of Homoptera, preparatory to a Catalogue for the Tyneside and Berwickshire Naturalists’ Clubs, of the species found within their respective districts, I have met with several apparently uncharacterized, which, in pursuance of the designs of these Institutions, I intend, in this communica- tion, to describe. From the localities examined being not very remote, many species are common to both; it appears, on this account, advisable, to obviate the disadvantages that attend scattered descriptions, to group the new species together. The species of the branch of the order treated of have been pretty well elaborated by Mr. Curtis, in his valuable work on British Ento- mology; there, doubtless, however, still remain gleanings to reward a diligent investigator. From the beauty, the occasional singularity, the limited number of its objects, the ease of conser- vation, and the facility of displaying their forms, this division offers many claims for a more general attention than it has hitherto had accorded to it.

Minute; head moderately pointed ; face entirely bluish black ; top of the head, whitish, with an arched row of six fuscous spots round the apex, followed by two larger ones united at the tip of. the sunk vertical line, and behind these four others, two on each side, betwixt this line and the eyes; eyes subtestaceous ; antennz moderate, greyish; ground colour of the thorax dirty white, occupied on the hinder part by two lateral, and two middle darker patches, the last disposed in thickish lines, bluish fuscous; scutellum white, a fuscous spot at its base, and another near its tip, behind the transverse impressed line; viewed from before, these form a cross; elytra glossy with fuscous or purplish-fuscous patches, one large near the base, and two others divided by narrow lighter spaces, with a few more minute, the remainder sub-hyaline, and diversified by the pearly whiteness of the ner- vures, more particularly at the junctions; wings slaty with dusky nervures ; breast and abdomen beneath, black, the segments of the latter bordered posteriorly with delicate white lines ; legs, base of the fore coxe, and of all the femora, base of the tibiz narrowly, their tips, and a line of dots, and the tarsal claws, black, the remainder, yellowish; hinder tibie, with the base narrowly, and the spines, as well as the basal joint of the tarsi, dirty yellow, the remainder, black. Length 1 line. Among short herbage, on barren banks, in Berwickshire. It comes nearest to A. nitida, of Curtis. 4 A. MARMORATA., Shining and polished, elongate ; face broad, somewhat flattened, yellow, an elongated spot on the clypeus, the margins of the compartments, an oblique dash across the cheeks, the under margin of the eyes, and two spots on their anterior edge, and the hollow whence the antennx originate shining black or fuscous, the central plate ribbed with black and yellow, representing in the contour the trunk of a skeleton, towards the lower part of which lies a halbert-shaped yellow space; ocelli remote, placed near the eyes, and within a dark spot, almost on the line of the forehead ; the upper part of the head is narrow, almost transverse 498 MR. HARDY ON DESORIPTIONS OF SOME lunate, as in Macropsis, but with an approach to triangular, the apex obtuse, yellowish, four minute points on the frontal line between the ocelli, and four placed 2 and 2 obliquely, the larger . pair anteriorly and most approximated, black ; a small sunk line on the vertex, edged as well as the posterior margin, with tarnished orange; eyes liver-brown; antenne with the second joint dusky, the bristle longish; thorax transverse lunate, the fore part yellowish, the hinder and the disc ashy, the surface varied or spotted with fuscous or black; scutellum large, yellow- varied with fuscescent, two yellow cheques at the base containing each a central black spot, transversely impressed, and somewhat depressed after the middle, with two black spots behind the im- pression ; elytra long, not much expanded after the middle, across which they are rounded, the tips overlap each other, and the sides are rather compressed posteriorly; fuscous-ash, polished, varied between the nervures with numerous black points or atoms, single, united into rows, or abrupt longitudinal and cross lines, and by the pearly whitness of the nervures, especially where they fork or cross each other, apical margin nigro-fuscescent; wings nigrescent with dark nervures; abdomen above, bluish black, posterior edges of the segments narrowly whitish, which colour at the margins extends into minute yellow triangular spots, issuing from a yellow lateral stripe, that towards its termination throws a band across the fifth; the underside is varied with fus- cous and yellow, the lateral and posterior margins of the seg- ments being yellow, and the centre fuscescent, with traces of a central yellow line, the apical segment set around the apex with stiff whitish bristles; fore and middle breast black, with the posterior margins, a spot on the pleure and hinder breast, except- ing the piceous base, yellow; legs whitish or yellowish white, apices of the fore and middle femora with two, of the hinder with six, curved spines, the fore tibie pectinated internally, and with five widely set spinules on the outer aspect, hinder ones internally ciliated, externally set with numerous spines; fore and middle coxe with a black patch at the base, their femora with two bands, the basal broader, and several spots, a line and several spots on the tibiw, and apices of the penultimate tarsal joint, NEW BRITISH HOMOPTEROUS INSECTS. 429 lilac or fuscous; posterior femora with a long longitudinal dash, a curved one near the apex, three or four apical spots externally, and one internally, lilac or fuscous; the long slightly bent tibie with two lines of minute, and one of large spots, sometimes also an internal line, the tips, spots beneath the first tarsal joint, its apex, those of the two succeeding joints, and the claws, black, Length, 3 lines. It is at once the largest and finest of its species. A specimen taken in the woods on the Derwent; and another in Berwickshire, beat out of bushes. As will be observed from the detail, this is a true Aphrodes, although the shape of the head would at first sight indicate a different relationship. Geyus [V.—ACUCEPHALUS, Germar. 1. A. apustus. Short, and, contrasted with its affinities, considerably narrowed, pale, or clayey-testaceous; face freckled with a brighter tint, dis- posed often in the merest rudiments of ribs, a spot in the hollow occupied by the antenne, and occasionally a line bordering the central part of the face, black; crown above triangular, scarcely wrinkled, with a central ridge, on each side of which it sinks down, and then rises in two indistinct oblique ridges, one on each side, either uniform in line, or often, as well as the thorax and elytra, freckled with atoms and minute specks of light brownish ; elytra rather abbreviated, with a row of ill-defined dusky spots along the costa, and turning round the tip, or uniform with the spots near the apex only; wings short, white; abdomen above either wholly pale, or varied with deep fuscous or black, the edges of all the segments pallid, a widish band at the apex of the second, the apical ones, and a stripe down the margins, in which lie several triangular brighter spots, brown ; underside concolorous, the centre dusky ; legs also concolorous, the tips of the anterior tibiee, and of the tarsal joints, blackish ; apex of the hinder femora with a patch before the apex, and the inner side of the tibiz, black, the spines brown ; apices of the tarsal joints and the claws piceous, Length 2—2+ lines. 430 MR. HARDY ON DESCRIPTIONS OF SOME Late in Autumn, in fields near Dunston, and also in Berwick- shire. I strongly suspect that this is a dwarfed and imperfect state of A. rusticus, Fab., which is confirmed by finding a still less de- veloped form to correspond to A. cardui. To A. rusticus, also, from observed varieties in specimens, I feel disposed to refer A. sparsus, A. rugosus, A. unicolor, A. fasciatus, and A. pallidus, of Curtis ; and his A. bicinctus is, perhaps, not different. . Genus V.—PAROPIA, Germar. 1. P. PALLIDIPENNIS. Megophthalmus pallidipennis, Curt. JZSS. Mus. Dom. Greville. Entirely pallid testaceous, in the elytra fainter, with the nerves and suture more dusky ; the eyes and extreme apex of the tarsi, black ; face and sides of the clypeus sometimes variegated with light ochreo-brumeous, and occasionally some dusky patches appear on the head and thorax, as well as a dusky spot on each side of the base of the abdomen; the elytra are considerably longer, and less gradually tapered behind than in P. scanica, Fallen, (Megophthalmus bipunctatus, Curtis). Length 132 2 Expansion of wings 3 lines. From the Bents, at South Shields ; a specimen likewise found in Berwickshire. Dr. Greville finds it near Edinburgh, and his specimens, named, he informed me, by Mr. Curtis, bear the appella- tion I have cited. Famity.—FULGORID A, Leach. Gunvus. VI.—CIXIUS, Latreiile. 1. Crxrvs DORSALIS. Head, eyes, and face fulvous, the ridges fainter, the cheeks and the apex of the face black, two dusky patches on the crown, and two smaller curved ones before the ridge anterior to them, fuscous ; thorax black, the anterior segment, the hinder part of the ridges, and a fine dorsal line shortly, fulvous ; elytra white, the nervures formed by black punctures, a broad fuscous patch down each, leaving the sutural region narrowly, excepting four outlying patches, and the costal portion gradually extending in width to NEW BRITISH HOMOPTEROUS INSECTS. 431 the apex, white, three blackish spots before or about the middle of the costa, and another paler towards the tip, with faint clouds on the cross nervures; wings white, with brown nervures ; abdomen above black, with two large spots, one on each side, at the base, a stripe down the sides, the posterior edges of the seg- ments narrowly, but wider at the sides, orange; beneath dark fuscous, with the posterior edges of the segments narrowly yellow ; a white flaky excreture collected round the apex ; breast black, with the posterior edges of its sections, yellow; legs dirty yellowish ; fore cox except at the tips, middle portion of the femora, continuous to the apex in the hinder, and the tips of the tarsi, more or less fuscous. Length 24 lines. Taken at Milne Graden, near Coldstream, Berwickshire, in June. This is, perhaps, a variety of Flata serratula, of Fab., which he says, occurs in England, upon Thistles. I have not met with any statements relative to the early stages of the insects of this genus. In woods, I often fall in with the larva of one species, which I take for C. nervosus, in cavities in the ground beneath large stones, or in the runs of moles or mice, where it may feed on roots or underground stems.
