 LETTER OF TRANSMITTAL. 
 
 AMERICAN MUSEUM OF NATURAL HISTORY, 
 
 New York, May 6, 1901. 
 
 SIR: I have the honor to transmit herewith a Bibliography and 
 Catalogue of the Fossil Vertebrata of North America. 
 
 I take pleasure in acknowledging the interest which you have shown 
 at all times in the preparation of this work. 
 
 I am, with great respect, your obedient servant, 
 
 O. P. HAT. 
 Hon. C. D. WALCOTT, 
 
 Directed of the U. S. Geological Survey,

 PREFACE. 
 
 The purpose of this bibliograpt^ and catalogue is to present a list 
 of all the species of fossil vertebrates which have been described, 
 up to the end of the year 1900, from all that part of the continent of 
 North America lying north of Mexico, and to furnish a guide to the 
 literature relating to all these extinct forms of organized beings. The 
 number of species is so great and the literature describing them is so 
 vast and so widely scattered that even the experts in the science of 
 vertebrate paleontology have great difficulty in making and keeping 
 themselves fulry informed as to what has already been done and what 
 is being done. It is hoped that this work will relieve students of 
 much tedious and often unavailing search. 
 
 This bulletin may be said to consist of three parts: First, a bibliog- 
 raphy which contains the titles of all the books, memoirs, and papers, 
 extended or brief, w r hich the author has been able to consult and which 
 have appeared to him to have a useful bearing on the subject; second, 
 a systematically arranged list of all the species of fossil vertebrates 
 which have been described from the region above indicated; third, an 
 index, alphabetical ly arranged, of all the systematic names occurring 
 in the volume. 
 
 In the bibliography there are given about 4,600 titles. Accompany- 
 ing each is a statement of the number of pages occupied by the work 
 and the number of plates or figures. If the memoir or paper is found 
 in some serial publication, the name of this is given together with the 
 volume and pages. All of the titles have been obtained through actual 
 examination of the scientific journals. In the case of many of these 
 the search has been made page by page, since the indexes are so often 
 deficient that they can not be wholly relied on. The end in view 
 throughout has been to find all that the paleontologist will need in his 
 work and to give correct citations. 
 
 The titles of works and papers are given under the names of the 
 authors, and these authors' names are presented in alphabetical order. 
 Each author's papers are arranged in the sequence of the } T ears of pub- 
 lication. Each title is preceded by the author's name, the year of 
 publication, and a letter of the alphabet, A, B, C, etc., according to 
 the number of papers published during that year, as "Leidy, J., 1868 
 A," "1868 B" to "1868 J." If an author has issued more than 26
 
 PREFACE. 
 
 in an}' year, the additional papers are indicated by the letters 
 A A. IW, etc. Thus we have "Cope, E. D., 1884 JJ." It must be 
 understood that it is not here implied that the papers of any author 
 in any year have been issued in the order in which they follow each 
 other iri this bibliography. In the case of an author who, like Pro- 
 fessor Cope, was publishing numerous memoirs, papers, and notes in 
 many journals and Government publications, it is manifestly almost 
 impossible to ascertain the exact order of issue. If any student 
 should be under the necessity of determining such order, he will have 
 to address himself to the task. 
 
 How successful the writer has been in collecting a complete list of 
 species only practical use of the book will prove. What has been 
 spoken of above as a list of the known species is, however, far more, 
 for under each species each genus and each group of higher rank 
 represented by any North American fossil species there has been 
 included references to the literature appertaining to it that is, to 
 put it in another way, each paper and memoir and book cited in the 
 bibliographical portion has been examined, and the proper citations of 
 it have been recorded under the species, genera, etc. , of the catalogue 
 of species. An estimate has shown that there are over 40,000 citations 
 recorded. Nevertheless, it is not improbable that some important 
 things have escaped attention. 
 
 In the catalogue the writer has not usually cited directly the place 
 of publication of authors' papers, but has referred to them as notated 
 in the bibliography. If, to give an illustration, the student rinds 
 under Ceratops the citation, "Marsh, O. C., 1888 C, p. 477," he must 
 turn to the list of Professor Marsh's papers for the year 1888 and 
 run down the list to the letter C. He will find there the complete 
 title of that paper, place of publication, etc. This method of citation 
 has been adopted for the following reasons: (1) To economize labor 
 in the preparation of this book. The writer does not feel that it 
 could ever have been completed had he been compelled to cite the 
 journal and volume according to the usual method for all of the approx- 
 imately 40,000 references herein contained. (2) To bring the size of 
 this bulletin within limits convenient for use. To refer to papers 
 in the usual way, even with intelligible abbreviations, would have 
 increased the size of this volume probably 50 per cent or more. 
 (3) Because the writer believes that, on the whole, the method here 
 employed will save the time of the student. If the place of publica- 
 tion alone is given, no clue whatever is afforded to the nature of the 
 paper. It may or may not contain something of value to him. In 
 this bulletin he has the complete title. If he is studying the dentition 
 of a fossil vertebrate, and the paper which he rinds cited deals with 
 the vertebrae, or the carpus, or the habits of the animal in question, he 
 needs to go no further. The time saved in making one trip to a
 
 PREFACE. 1 1 
 
 library will compensate for any trouble undergone in turning from 
 the catalogue to the bibliography. This method of reference, with 
 some modifications, is in frequent use by scientific writers, though it 
 has probably not been employed before on so large a scale. 
 
 Some further explanation may be made regarding the systematic 
 portion of this work. Under each genus and species there will be 
 found, first of all, a reference to the original description. This is 
 followed by the other citations, arranged according to authors in 
 alphabetic order, years of publication, and symbols. If the author 
 cited has employed a generic or specific name different from the one 
 adopted, this is thrown in parenthetically after the citation. 
 
 The writer has arranged the classes, orders, families, and genera of 
 our fossil vertebrates according to what has seemed to him to be their 
 natural relationships. This has appeared to him to be preferable to 
 arranging them all alphabetically, although he does not overlook the 
 advantages of the latter method. On the other hand, the species of 
 each genus is here disposed in alphabetical order for the reason that 
 it will save much time in finding them, while attempts at giving them 
 a natural arrangement are often futile. 
 
 As regards nomenclature the writer has followed the rules of the 
 American Ornithological Union, because he believes that they meet 
 the requirements of systematic work more completely and consistently 
 than those adopted by any other body of zoologists. 
 
 The coming years will surely witness a great increase in our knowl- 
 edge of the beings which in past ages have peopled our continent. As 
 a result of discoveries and investigations many new forms will be 
 described, while again perhaps many genera and species which are now 
 accepted will be reduced to synonomy. This will, before many years, 
 make obsolete many of the names here adopted, but it is the purpose 
 of this work to facilitate just such discoveries and investigations and 
 changes. 
 
 The writer takes pleasure in expressing his obligations to many 
 friends for assistance and encouragement in prosecuting his work on 
 this volume. Encouragement has been afforded by all, or nearly all, 
 of the vertebrate paleontologists of the United States, and as many as 
 have been applied to have given the information desired. Financial 
 assistance has been given by the Smithsonian Institution, and for this 
 acknowledgments are due, especially to its officers, Secretary S. P. 
 Langley and Assistant Secretary Richard Rathbun; and to Hon. C. D. 
 Walcott, director of the United States Geological Survey. Acknowl- 
 edgments are due to Dr. Theodore Gill for advice with regard to 
 matters pertaining to nomenclature, to scientific literature, and to classi- 
 fication. It must not, however, be inferred that he is responsible for 
 any innovations that have been made. Dr. Leonhard Stejneger, cura- 
 tor of the department of reptiles, United States National Museum, has
 
 12 PREFACE. 
 
 aii<\vrr'<l many questions with regard to nomenclature and has given 
 assistance in other ways. The classification of the birds here adopted 
 is, with slight modification, that proposed by him in the Standard 
 Natural History, 1885. Prof. Frederick A. Lucas, assistant curator 
 of the department of comparative anatomy, United States National 
 Museum, has been helpful in many ways, and to him is due the final 
 disposition of certain of the genera and species.

 1 By most authors this family is called Acanthodidas. The change is necessitated by adopting the 
 earlier generic name Acanthoessus for Acanthodes. 
 
 2 The law of priority, which lies at the base of all codes of nomenclature, requires the restoration of 
 the name first given by Agassiz to this genus.

 >This superordinal name is employed to include all Elasmobranchii except the Ichthyotomi. The 
 living sharks and rays may be regarded as constituting the types of the group. It is quite probable 
 that a more complete knowledge of the Paleozoic families will cause them to be removed from 
 association with the yet living families.

 The term Pisces is employed here in much 
 the same sense in which it was used originally 
 by Linnaeus; that is, to designate the fish-like 
 animals, exclusive of the sharks and rays and 
 the lampreys. There are furthermore included 
 certain fossil groups and the Dipnoi, not known 
 to Linnaeus. The authors cited above use the 
 term in various senses, and some employ other 
 terms to designate this group.

 The name Mesodon was employed by Rafin- 
 esque for a mollusk in' 1819. According to 
 Mr. A. S. Woodward, Typodus is probably a 
 
 synonym of Mesodon, and is here accepted pro-

 Dr. E. Koken, in Zeitschrift deutchen geolog. Gesellsch., vol. xl, pp. 274-305, pis. xvii-xix, has 
 described, from the Tertiary deposits of Alabama and Mississippi, the following list of otolites of fishes, 
 designating the families, in some cases the genera, to which these otolites probably belonged. The 
 word Otolithus being evidently not regarded as a generic name, the specific names have no standing 
 in the system of nomenclature. 
 
 On the subject of the otolites of fishes see also Higgins, E. T. 1867 A., and Koken, E. 1891 A.

 Cope's species T. princcps is last mentioned, 
 and then only incidentally, in 1869 M, pp. 160,167. 
 It appears to have been regarded by Cope as a 
 synonym of T. strenuus. In the Cope collection 
 of reptiles the present writer has found the 
 femur described on p. 166-B of Cope 1869M, and 
 it has written on it, probably by Cope himself, 
 the name " Prochonias princeps."

 No species certainly belonging to this genus 
 have yet been described from North America. 
 For Chelonia couperi see Harlan, R. 1842 B, p. 
 144, pi. iii, figs. 2,3; but it is probable that the 
 bone there described and figured is not even a 
 portion of a turtle. See also J. H. Couper in 
 Hodson, W. B. 1846 A, p. 46, for mention of this 
 supposed turtle.

 It is highly probable that none of the species 
 here recorded under Trionyx really belongs 
 under the genus as understood in recent works 
 on living turtles, especially as the genus was 
 restricted by Wagler in 1830. See Dr. Baur as

 Unless otherwise indicated, this genus is re- 
 ferred to by the following writers under the 
 name Ichthyosaurus. Proteosaurus, however, 
 clearly has priority. On this point see R. Ly- 
 dekker in his "Catalogue Fossil Reptilia," pt. 
 ii, p. vii. Although no species of this genus 
 has as yet been, with certainty, discovered in 
 America, a knowledge of its structure is essen- 
 tial in understanding the genus Baptanodon; 
 hence citations of the literature are given.

 Unless otherwise indicated the following 
 authors refer to this genus under the name 
 Pterodactijlus. The latter name is usually cred- 
 ited to Cuvier, 1809, Ann. Mus., xiii, p. 424. 
 There, however, we find only the French term 
 Petro-dactylt. Even in case this is a misprint 
 for Pterodactyle, it is inadmissable as a generic 
 name. Pterodactylus appears to have heen used 
 first in 1824 by Cuvier.

 FOSSIL VERTEBRATA OF NORTH AMERICA. 
 
 [BULL. 179. 
 
 ICHNITES. 
 
 The imprints of the feet of animals on the rocks have been described under various general names, 
 such as Ichnites, OrnithUes, Ornichichnites, Ornithoidichnites, Sauroidichnites, Batrachoidichnites. The 
 first attempt to place under generic names the various .forms found in North America was made by 
 President Edward Hitchcock in 1845 ( Hitchcock, E. 1845 B) . This communication the present writer has 
 made the basis for both the generic and the specific names. Many of the names, both generic and spe- 
 cific, were afterwards changed; but this was done in violation of the rules of nomenclature as now 
 recognized. On account of the impossibility of determining with certainty the systematic positions 
 of the animals which made the tracks described, the " genera " are arranged alphabetically.

 This is not the Palamopw E. Hitch, of 1848 and

 Eupalamopus. Since E. Hitchcock's Macropterna

 necessary to refer here also the other species of 
 Macropterna.

 Originally four species, S. adamsumts, S. tetra- 
 dactylus, S. gracilior, and S. rogersianus, were as- 
 signed to this genus. The last-named belongs 
 under Palamopus. Later (1848) Hitchcock re- 
 ferred the first three species to Ornithopus, a 
 new genus. As Sillimanius was based on de- 
 scribed and figured forms, Ornithopus becomes 
 a synonym.

 After 1884 Prof. Cope regarded this species as 
 based on what was probably an incisor tooth of 
 Polymastodon taoensis Cope. Should Cope's 
 identification eventually prove correct, the 
 name Txniolabis will supersede Polymastodon. 
 
 The name scalper appears to be merely a 
 substitute for the earlier T. siUcatm.

 The North American species of this genus 
 have been greatly confused, and many of the 
 identifications of authors are erroneous. In 
 this work the species are accepted on the au- 
 thority of Mr. j. W. Gidley, of the American 
 Museum of Natural History, New York, who 
 has made an exhaustive study of them. His 
 paper appeared in the Bulletin of the Museum, 
 vol. xiv, 1901, pp. 92-142. He is not to. be held 
 responsible for the citations that are made 
 under the various species.

 Remains supposed to belong to the same spe- 
 cies as our domestic horse have been found in 
 various places in North America. In some cases 
 the identifications have been open to question; 
 in other cases the remain., may have been de- 
 rived from the introduced race. The former 
 existence of the species in Alaska and in Cali- 
 fornia appears well established.

 This species has been reported from various 
 parts of the United States, North Carolina, South 
 Carolina, New Jersey, Nebraska, and from de- 
 posits ranging from the Miocene to the present; 
 but it is most probable that all the remains 
 have been derived from the introduced race.

 The generic name Merycoidodon clearly has

 withstanding the fact that it has been discarded 
 by Leidy himself and succeeding writers. Un- 
 less otherwise indicated, the following authors 
 employ the name Oreodon.

 Dr. W. D. Matthew (1899 A, p. 72) has attrib- 
 uted to Cope a species, Merychyus euryops, but 
 search has failed to discover the name in any 
 of Cope's papers. It is probably a manuscript 
 name only.

 Earle (1892 A, p. 164) makes this species a 
 synonym of C. anax. Should it result that the 
 specimens described as C. anax, C. pachypus, 
 and C. lobatus belong to one species, this must 
 bear the name C. lobatus, this name having pri- 
 ority of publication. This course has been fol- 
 lowed by Osborn 1898 H, p. 204.

 1 The generic title Loxolophodon was first employed by Professor Cope for Bathmodon semicinctus, now 
 regarde 1 as a species of Coryphodon. Later Professor Cope used the name for the genus here called 
 Tinoceras. In this sense the type was L. cornutus (Cope, 1884 O, p. 572).
