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, Washington, D. C. 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.

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. HAY.] CATALOGUE. Subclass ASPIDOGANOIDEI Gill. 339 Gill, T., 1876, Johnson's Univ.

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.

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. Bouve, T. T. 1859 B.

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. Sillimanius gracilior E.

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. Equus complicatus Leidy. Leidy, J. 1858 C, p. 11. Blake, C. C. 1863 A, p. 28. (E. nearcticus Blake.)
