Dr. Hunter, of Braidwood, also has a large collection of INTRODUCTION. XI fish-remains from the Scottish Carboniferous; the Edin- burgh Museum has been greatly enriched during recent years by the labours of Dr. R. H. Traquair, F.R.S., in that ‘district ; and numerous specimens have been obtained from the same prolific field by Messrs. T. Stock, W. T. Kinnear, and others. In England, the late Mr. Thomas Atthey made the unique collection of Amphibia and Fishes from the Northumberland Coal-field now in the Newcastle- upon: Tyne Museum ; and for many years Mr. T. P. Barkas, F.G.S., systematically collected from the same area, pre- senting some specimens to the British Museum, others to the Newcastle Museum, and retaining others in his private collection. Mr. John Simm and Mr. T. Cragges, of \Vest Cramlington, and Mr. Joseph Taylor, of Shire Moor, have also done much in their respective districts ; and to Mr. Cragges is due the series of microscopical sections of teeth from the Coal-Measures, described by Sir Richard Owen in 1867, and now in the British Museum. The finest collection of English Coal-Measure Fishes, however, is that of Mr. John Ward, F.G.S., of Longton, who, by donation and exchange, has supplied specimens to most of the principal Museums in the country. Mr. Ward’s collection comprises a large number of type specimens described by Egerton, Young, and Traquair, and is also unique from the circumstance that the precise horizon of each fossil is recorded.* The Coal-Measures of Yorkshire have been especially investigated by Mr. James W. Davis, F.G.S., of Halifax, who has a large collection, comprising the types of species made known in various papers. The Lower Carboniferous of England and Wales yields only fragmentary fish-remains, chiefly the teeth and spines of sharks, well represented in the British Museum and the Museums of Bristol and York.

Wood, F.G.S., of Richmond, and by Mr. William Horne, F.G.S., of Leyburn, whose collections. are now in the York Museum; and a series of teeth entirely detached from matrix has been obtained from South Derbyshire by Mr. Edward Wilson, F.G.S., this being now in the British Museum. The limestone of Oreton,. Shropshire, was explored by the late Messrs. T. Baugh, of Bewdley, and Weaver Jones, of Cleobury Mortimer, whose collections are also in the British Museum; and the Bristol limestone is especially well represented in the Museum of that city, where many of the types described by Agassiz are preserved. In the Carboniferous Lime- stone of North Wales, Mr. G. H. Morton, F.G.S., has discovered several Selachian teeth; and in the North of Ireland, the late Admiral Jones and the Earl of Ennis- killen made the unique collection of Selachian teeth and spines now in the British Museum and the Museum of the Geological Society of London. The Permian fishes of Durham seem to have been first collected by Mr. Henry Witham, of Lartington,. whose fossils form the subject of the plates accom- panying Sedgwick’s classic memoir on the Magnesian Limestone. A large series is preserved in the Newcastle- upon-Tyne Museum, as also in the private collection of Mr. William Dinning, of Newcastle; and there is a good typical series in the British Museum. The Newcastle Museum is largely indebted to the labours of Mr. R. Howse* and Mr. James W. Kirkby, the former of whom,, in conjunction with the late Mr. Albany Hancock, was the first to make known the discovery of Reptilia and Amphibia in the English Permian. British Triassic Vertebrata are very rare, and chiefly represented in the Museums of Warwick, Shrewsbury, ° * R.

Xii Bristol, and Elgin, the British Museum, Museum of Practical Geology, and the Edinburgh Museum of Science and Art. Fishes are few and scattered, one prolific stratum only having been discovered near Nottingham.* Labyrinth- odonts constitute a leading feature of the Warwick Museum ; while the Reptilian skeletons met with in the Elgin Sandstones are most nearly complete, and have been principally obtained through the researches of the Rev. George Gordon, LL.D., of Birnie. The only known specimens of Ze/erpeton, except the type, were discovered by Mr. James Grant, of Lossiemouth, in whose collection they are still preserved. British Rhetic Fishes and Reptiles occur only in a very fragmentary state, and are well represented in the British: Museum and the Museums of Bath, Bristol, and Leicester. The E. T. Higgins Collection of Aust Cliff fossils at Bristol comprises an unique series of teeth of Ceratodus ; and the Charles Moore Collection at Bath, from the Rhetic fissure near Frome, contains the tecth of the British Rhetic Mammal, J/icrolestes mooret. Both Fishes and Reptiles are met with in certain horizons of the English Lias in several localities. The late Mr. Thomas Hawkins collected the Liassic Ichthyo- sauria and Plesiosauria forming the greater part of the series in the British Museum; and the late Mr. James Harrison, of Charmouth, discovered and disentombed the fine skeleton of Sce/idosaurus in the same collection. Miss Mary Anning was for several years a well-known collector at Lyme Regis; Miss Philpot made a large collection of Lyme Regis fossils, afterwards presented to the Oxford Museum; and Messrs. James and Henry Marder, for a long period, supplied many Museums and private cabinets from the same locality. The combined collections of the late Earl of Enniskillen and Sir Philip * E.

Egerton, now in the British Museum, form the most ex- tensive series of Fossil Fishes from the English Lias hitherto obtained, and include many type specimens de- scribed by Agassiz and Egerton. The Warwick Museum has a noteworthy collection from the Lias of the district ; the Leicester Museum possesses a_ typical series of Fishes and Reptiles from Barrow-on-Soar, lately much extended by the researches of the curator, Mr. Montagu Browne, F.G.S.; and the fine collection of the late Mr. William Lee, made in the same locality, is now in the Dublin Museum of Science and Art. The collection of the late Mr. Charles Moore, F.G.S., in the Bath Museum, comprises an extensive series of similar fossils from Somer- setshire and Gloucestershire, all in an unusually fine state of preservation. The Upper Lias of Whitby is well repre- sented in the Museums of that town, Malton, and York, as also in the British Museum. Foremost among the collectors may be mentioned the late Messrs. Ripley and Brown Marshall, of Whitby; and, as the result of re- searches pursued for a period of fifty years, Mr. Martin Simpson, curator of the Whitby Museum, has been able to define the stratigraphical horizonsin which the remains occur, besides adding many specimens to the local collection.* The most extensive series of remains from the Lower Oolites are those in the Oxford Museum, the British Museum, and the private collections of Mr. James Parker, F.G.S.,. of Oxford, and Mr. Thomas. Jesson, F.G.S., of Northampton. The Middle and Upper Oolites are especially represented in the British Museum, the Museums of Cambridge and Oxford, and the private collections of Mr. Marshall Fisher, of Ely, and Mr. Alfred N. Leeds, of Eyebury, near Peterborough. Mr. Fisher has obtained a large series of remains, especially marine Reptilia, from the Kimeridge Clay of Ely; and * M. Simpson, 7he Lossils of the Yorkshire Lias, 1855 (and ed. 2, 1884). INTRODUCTION. XV with the exception of the great Omosaurius, due to the generosity of the Directors of the Swindon Brick and Tile Company,* the British Museum owes all its finer Reptilian fossils from the Kimeridge Clay of more southern areas to the researches and liberality of Mr. J. C. Mansel- Pleydell, F.G.S., who has also presented a Pliosaurian paddle to the Dorchester Museum. ‘The late Dr. Henry Porter, of Peterborough, obtained various Teleosaurian, Ichthyosaurian, and Plesiosaurian fossils from the Oxford Clay of that neighbourhood, now for the most part in the Woodwardian Museum, Cambridge; and the unrivalled collection of Mr. Alfred N. Leeds, made in the same locality, comprises not only Dinosauria and numerous nearly complete skeletons of Teleosauria, Ichthyosauria, and Plesiosauria, but also many fish-remains. The Purbeck Vertebrata of Swanage seem to have been first systematically collected by the late Messrs. W. R. Brodie and C. Wilcox, and the formation is well represented in the Museums of London, Cambridge, and Dorchester. The most extensive series of Mammalian fossils and the remains of dwarf Crocodiles, now in the British Museum, were discovered by Mr. S. H. Beckles, F.R.S.; and, as the result of systematic purchases, the late Earl of Enniskillen and Sir Philip Egerton accu- mulated the unique collection of Fossil Fishes from the same horizon, now also in the British Museum. Fossil Fishes likewise occur in the Purbeck Beds of the Vale of Wardour, Wiltshire, and were collected many years ago by the Rev. P. B. Brodie, F.G.S., and more recently by the Rev. W. R. Andrews, F.G.S., of Teffont, in whose private collections the majority are still preserved. The Vertebrata of the Wealden were first collected in the classic neighbourhoods of Cuckfield and Hastings, in * W.

Hoimes, of Horsham, and Mr. S. H. Beckles, F.R.S., of St. Leonard’s, obtained most of the Reptilian fossils described in the early memoirs of Mantell,. Melville, and Owen, while Major Lambert Brickenden also added a few noteworthy specimens. The Mantellian Collection was purchased by the British Museum in 1838. and 1853; that of the late Mr. Holmes has recently been acquired by the Brighton Muscum; and that of Mr. Beckles. is still at the residence of its founder at St. Leonard’s. The Rev. William Fox, of Brixton, collected numerous remains of Dinosaurs from the Wealden cliffs on the south coast of the Isle of Wight, discovering the fine examples of Ornzth- opsis, Polacanthus, Hypsilophodon, and other genera now in the British Museum; while Mr. J. W. Hulke, F.R.S., has obtained an important series of bones from the same locality, including the type skeleton of /gwanodon seelyt and other specimens described in hisown memoirs. During recent years, Mr. Charles Dawson, F.G.S., has greatly extended the collection of the British Museum, by adding numerous discoveries from Sussex localities, including the type specimens of three new species of /euanodon. Except in the Potton Bone-bed, which chiefly consists of remanié fossils from the Kimeridge Clay, Vertebrata of Lower Greensand age are rare in Britain, the only unique specimens being the type skeleton of /ewanodon mantelliand the group of Dinosaurian bones from Hythe (Dinodocus mackesont), discovered by Mr. H. B. Mackeson, F.G.S., and presented by him to the British Museum. The Upper Cretaceous formations, however, have proved more prolific, the Cambridge Greensand consisting largely of reptilian bones and teeth, and the Gault and various divi- sions of the Chalk furnishing numerous specimens both of Reptiles and Fishes. The Cambridge Greensand is natur- ally best represented in the Weodwardian Museum, Cam- INTRODUCTION. XVI bridge ;* but there are numerous fine fragments also in the British Museum, Museum of Practical Geology, York Museum, and the private cabinet of Mr. Thomas Jesson, F.G.S., of Northampton ; and few collections of importance are destitute of a typical series of specimens. The Verte- brate fossils of the Gault are more satisfactorily preserved than those of the Cambridge Greensand, and are represented in the British Museum, Museum of Practical Geology, and the Woodwardian Museum, to which they have been chiefly supplied, either directly or indirectly, by the experienced collector, Mr. John Griffiths, of Folkestone. Chali fossils are seen in most Museums, and the Fishes usually occur in an exquisite state of preservation. The late Dr. Gideon A. Mantell, F.R.S., as in the case of the Wealden Verte- brata, was a pioneer in the collection of those of the Chalk of Sussex ; and the numerous fine examples of his patient work of extrication now in the British Museum are described and figured both by Agassiz and by himself. Mr. Frederic Dixon, of Worthing, author of the well-known Geology and Fossils of Sussex,t the late Dr. J. S. Bower- bank, F.R.S., and Mrs. Smith, of Tunbridge Wells, also obtained the type specimens of many of the species of Fossil Fishes and Reptiles discovered in the Chalk of Sussex, Kent, and Surrey, at present, with rare exceptions, preserved in the British Museum; and for a long period Mr. Henry Willett, F.G.S., of Brighton, has been engaged in collecting the unrivalled series of Chalk fossils, now presented to the Brighton Museum.

Harford has prepared for study a large number of Fossil Fishes from the Chalk of Kent, lately acquired by the British Museum; and Mr. S. J. Hawkins, F.G.S., has a private collection of similar specimens beautifully extricated from the matrix. Many collectors. and museums are indebted to Mr. Joseph Wood for the discovery of fine specimens in the Chalk of Kent. Eocene Vertebrata are abundant both in the London and Hampshire Basins, and most Museums have repre- sentative series. In the early part of the century, Bower- bank collected from the London Clay of Sheppey, and Dixon from the Bracklesham Beds of Sussex and the Barton Clay of Hampshire; Mr. Searles. V. Wood, F.G.S., author of the Crag Mollusca, explored the cliffs of Hordwell; the late Barbara, Marchioness of Hastings, chiefly with the help of Mr. Henry Keeping, obtained a large series of Reptilian and Mammalian fossils from the Upper Eocene of Hordwell and the Hempstead Beds of the Isle of Wight ; and the late Earl of Enniskillen and Sir Philip Egerton accumulated an extensive collection of fish-remains from various formations and localities in both basins. All these collections, which comprise the types of most species of British Eocene Vertebrata hitherto described, have been finally acquired by the British Museum, that of Mr. Searles Wood being presented and the others obtained by purchase. To Mr. W. H. Shrubsole, F.G.S., of Sheerness,. palzontologists are mainly indebted for the numerous dis- coveries of Vertebrata in the London Clay of Sheppey during the last twenty years, and all his principal specimens are also now in the British Museum. The Crag Deposits of Suffolk and Norfolk yield the remains of Pliocene Vertebrata mingled with those of Miocene and Eocene age, derived from earlier strata. Since the opening of the phosphate diggings in 1840, large collec- tions have been made by the late Messrs. James Baker and W. Whincopp, of Woodbridge, these being acquired by IVTRODUCTION. XIX Mr. Edward Charlesworth, F.G.S., and afterwards purchased by the British Museum, Museum of Practical Geology, Woodwardian Museum, and the York Museum. The col- lection of the Rev. H. Canham is now inthe Ipswich Museum; Mr. W. Colchester, F.G.S., has obtained many specimens, still in his private cabinet; and the unique series at York is due to the generosity of Mr. William Reed, F°.G.S., who has for many years made special efforts to render the col- lection complete. The only supposed British Pliocene Vertebrate discovered elsewhere than in the Eastern counties is the Evephas meridionalis from Dewlish, Dorset, of which a tooth was presented to the British Museum by Mr. J. C. Mansel-Pleydell, F.G.S., in 1888. The Mammalian and other fossils of the Norfolk Forest Bed have long been collected, and among the principal explorers of this deposit may be mentioned the late Mr. Samuel Woodward, the late Revs. C. Green, J. Layton, and S. W. King, the Rev. John Gunn, F.G.S., Mr. Randall Johnson, Mr. RK. Fitch, F.G.S., Mr. A: Savin, of Cromer, Mr. J. J. Colman, of Corton, Mr. James Backhouse, F.G.S., of York, and Mr. Clement Reid, F.G.S., of the Geological Survey. The Green and Layton Collections are now in the British Museum; that of the Rev. S. W. King, in the Museum of Practical Geology; and those of the late Samuel Woodward and the Rev. John Gunn, in the Norwich Museum. The collections of Messrs. Fitch, Savin, and Backhouse are still in the possession of their respective founders, and that of Mr. Randall Johnson is now for the most part in the cabinet of Mr. J. J. Colman, M.P., of Corton. Pleistocene Mammalia occur in all Museums, and a general sketch of their distribution, so far ascertained to the year 1869, is given by Professor Boyd Dawkins, F.R.S.* The large collections of the late Mr. John Brown, ot Stanway, from Essex; of Mr. J..J.

Spurrell, F.G.S., made in the neighbourhood of Crayford, is still in their possession at Belvedere, and comprises several specimens described by Falconer, Daw- kins, and Sanford. The fine series of remains obtained by Mr. Henry Keeping from the river gravels of Barrington, near Cambridge, is for the most part in the Woodwardian Museum and in the British Museum; Dr. Blackmore’s discoveries in the river gravels of Fisherton, near Salisbury, are preserved in the Salisbury Museum ; and most of the early isolated discoveries by private collectors, noticed in Owen’s Lritish Fosstl Mammals and Birds, have finally reached the British Museum. The most extensive series of Mammalian remains from the Turbary of Walthamstow, Essex, is also in the British Museum, having been col- lected by Mr. Joseph Wood.? The largest collections of Pleistocene Mammalia have been obtained from caverns,§ in the exploration of which Mr. Whidbey (or Whitby) and Dr. Buckland were the pioneers in Britain. At the instigation of Sir Joseph Banks, Mr. Whidbey explored the cave of Oreston, near Plymouth, and obtained the remains described by Sir Everard Home and Mr. W. Clift in the Phzlosophical Transactions for 1817 and 1823. The researches of the Oxford professor in the cave of Kirkdale, Yorkshire,|| led to the discovery of a large series of remains, now in the Museum of the University ; and the somewhat later investigations * W.

MacEnery in Kent’s Hole, near Torquay, were rewarded by the unearthing of numerous similar specimens, which were sold on that gentleman's death, and chiefly reached the British Museum and the Museum of the Geological Society.* The Caverns of Brixham and Kent’s Hole have been systematically explored by Committees of the Royal Society and the British Associa- tion, under the superintendence of Mr. W. Pengelly, F.R.S.; the principal specimens met with being presented to the British Museum, while a representative series is preserved in the Museum of the Natural History Society of Torquay. The Caverns of the Mendip Hills were explored by the Rev. D. Williams and Messrs. W. Beard, W. Ayshford Sanford, F.G.S., and Professor Boyd Dawkins, F-.R.5., whose discoveries now enrich the Taunton Museum; and the well-known Cresswell Caves, near Worksop, Derby- shire, have furnished to the Rev. J. M. Mello, F.G.S., Pro- fessor Boyd Dawkins, F.R.S., and Mr. T. Heath, the fine series of remains at present in the Museum of the Owens College, Manchester. The Victoria Cave, near Settle, was investigated by a Committee of the British Association, the resulting collection being now in the Museum of the Giggleswick Grammar School. From a cave in Teesdale Mr. James Backhouse, F.G.S., has made an important collection, now in his private Museum at York;ft and the contents of the fissures of Windy Knoll, Derby- shire, and Raygill, Yorkshire, are at present respectively in the Museums of Manchester and Leeds. The latest discoveries of Messrs. E. Bouverie Luxmoore, F.G.S., and Dr. Henry Hicks, F.R.S., in the caves of the Vale of Clwyd, near St. Asaph, have recently been presented to the British Museum.

Most of the collections mentioned have been consulted during the progress of the present work ; and though the magnitude of the task prevents its being a critical veswmé throughout, it is hoped that no labour has been spared in attempting to record the correct interpretation of doubtful points. Though all references are given at sufficient length to be understood without the aid of an index, the information has been condensed as far as possible, and the following statement will explain the general plan of the work :— (i) The genera and species are arranged alphabetically under their respective classes. (ii) All generic and specific names at present accepted are printed in antique roman type, while the cross- references to synonyms, and all undefined names, are printed in bold italics. (iii) Under each genus the synonyms are printed in SMALL CAPITALS, and under each species in #alics. (iv) When ascertainable, the nature and present whereabouts of the type specimen of each accepted species are stated in square brackets after the record of the locality; and in the case of synonyms, the types are similarly noticed immediately after the references. When the species at present exists, or when the type is a foreign specimen, the nature of the evidence on which that species is recorded as a British fossil is printed in ¢fadics. (v) The type species of every extinct genus, whether valid or not, is marked by an antique T. * V.

Xxill In attempting the execution of this plan, considerable difficulties have been met with in all departments, and the writers would claim indulgence for the numerous imperfections which critical studies must soon reveal, The publication of undefined names, for instance, has been a source of much inconvenience, especially among the Reptilia, in which a single University Museum is respon- sible for no less than seventy meaningless terms ; and the numerous hasty publications upon the same subject, which have appeared within recent years, have tended in no small degree to add to the confusion. While wholly responsible, however, for whatever im- perfections the work may contain, the writers are deeply indebted to the kindness of numerous friends and specialists in various departments, who have freely given advice, and, in many cases, read the proofs. To Mr. William Davies thanks are especially due for continual help, he having read the whole of the proofs, and given the writers the benefit of his long experience in connexion with the Fossil Verte- brata in the British Museum. To Dr. R. H. Traquair, F.R.S., Mr. James W. Davis, and Mr. John Ward, the writers are especially indebted for information concerning Paleozoic Fishes; and the accepted synonymy of the Coal-Measure Amphibia of Northumberland has been contributed by Mr. William Dinning, of Newcastle. The proofs of the Dinosaurian Reptiles have been read by Mr. J. W. Hulke, F.R.S.; and Mr. R. Lydekker has favoured the writers with continual advice concerning the higher Vertebrata, besides kindly permitting reference to numerous unpublished proof sheets. The section on Aves has been read by Mr. R. Bowdler Sharpe and Mr. E. T. Newton, to the former of whom is due the accepted nomenclature of the recent species. To Mr. G. A. Boulenger the writers are indebted for the revision of the nomenclature of recent Amphibia and Reptilia, in addition to numerous other notes; and Mr. Oldfield Thomas has kindly advised on all XXi1V INTRODUCTION. doubtful points concerning the synonymy and nomenclature of the Mammalia. Professor W. Boyd Dawkins, F.R.S., and Mr. E. T. Newton have also read the proofs of the Mammalian section, and pointed out many emendations resulting from their own special researches ; while Mr. Alfred Bell has contributed a series of notes and references, from which a few important omissions have been supplied. For much information concerning type specimens and old collections the writers are indebted to the Rev. George Gordon, LL.D., of Birnie, Mr. James Powrie, of Reswallie, Mr: Edward Wilson, of Bristol, Mr. H. M. Platnauer, of York, Mr. W. Rupert Jones, of the Geological Society, and many others ; and thanks are especially due to Mr. B. B. Woodward, of the Natural History Library of the British Museum, as also to Mr. J. Saunders, for much valuable help in bibliographical researches. Finally, the writers would tender their acknowledgments to Mr. F. Justen, of Messrs. Dulau & Co.,to whose kindly interest is due the publication of the work in its present form. LONDON, December 31st, 1889. Dates of publication of ‘Recherches sur les Potssons fossiles’... par L.

Belg., * The genus /guanodon was originally described from teeth, and subsequently from detached bones of various individuals. These detached teeth and bones were considered by the earlier observers to belong to one species, for which the names 1. anglicum, F. Holl, 1829, and /. mante/li, H. von Meyer, 1832, were proposed ; but it was not until 1851, when R. Owen described a large portion of one individual (the Zguanodon of ‘G. F.,' i.e., Bensted’s specimen), that the species mantfel/i became satisfactorily defined. There is, therefore, doubt as to the specific identity of the various bones described before 1851, and we follow Dollo and Hulke in con- sidering Bensted’s specimen, now in the British Museum, as the type of the typical species of the genus, R 442 BRITISH FOSSIL VERTEBRATA.

Among the Pleistocene Mammalia, mere lists of occurrences not verified by specialists are ignored ; and it has been necessary to omit many records, from their being noted without scientific precision under English names. The term ‘Prehistoric’ is employed in the sense defined by Professor Boyd Dawkins. 197 LONDON : Printed by SrRANGEWaYs AND Sons, Tower Street, Cambridge Circus, W.C.
