SMITHSONIAN MISCELLANEOUS COLLECTIONS. . 230 ARRANGEMENT FAMILIES OF MAMMALS. WITH ANALYTICAL TABLES. PREPARED FOR THE SMITHSONIAN INSTITUTION. BY THEODORE GILL, M.D., Ph.D. WASHINGTON: PUBLISHED BY THE SMITHSONIAN INSTITUTION. NOVEMBER, 1872. ADVERTISEMENT. The following list of families of Mammals, with analytical tables, has been prepared by Dr. Theodore Gill, at the request of the Smithsonian Institution, to serve as a basis for the arrangement of the collection of Mammals in the National Museum ; and as frequent applications for such a list have been received by the Institution, it has been thought advisable to publish it for more extended use. In provisionally adopting this system for the purpose mentioned, the Institution, in accordance with its custom, disclaims all responsibility for any of the hypothetical views upon which it may be based.

BIBLIOGRAPHY, OR LIST OF AUTHORS REFERRED TO (29) LIST OF AUTHORS REFERRED TO. The following enumeration of works is chiefly intended to explain the abbrevia- tions used in connection with the preceding list of families : the works most accessible to students generally have been used, whenever they could be referred to in explanation of the limits of families adopted ; special monographs have been chiefly referred to when the groups in connection with which they are cited have not been limited in the same manner in general works. The "Osteographie" of de Blainville, although not actually referred to in connection with any special family, is so indispensable to any investigator of the mammals, and has been so much used by the writer, that the title thereof and an analysis of its contents have been given ; the analysis and assignment of dates of publication of the several monographs will doubtless prove useful, and save to some time and labor like that necessarily devolved upon the writer in ascertaining the data furnished. For the information of students, and because it is information often desired, the publishers' prices of most of the works cited are given, in the currency of the country where they were published. Many of the separate monographs reprinted from journals can be obtained from the second-hand book dealers—especially the German—and from the Naturalists' Agency of Salem, Mass., but at varying prices. In order to secure uniformity of typography, only the initial letters of the charac- teristic words are capital, the example of the learned brothers Grimm, as well as other German writers, sanctioning such usage for their language. The initial letters, however, of the more important words of the general titles, and to which reference is made in the list, are capitalized, corresponding with and rendering at once intelligible the abbreviated references. The punctuation of the respective title-pages is adopted. The symbol ( < ) denotes that the memoir after which it is inserted is contained in the volume or series whose title follows ; the symbol of equality (=) denotes that the memoir is co-extensive with the volume.

[1839-1855.] The twenty-sixth and last fascicule was issued with the special title above given, titles for the four volumes of text and four of plates, table of contents and index, by the Baillieres in 1864. The subscription price was 2 francs 35 centimes per plate ; the price of the twenty-sixth livraison, 45 francs ; and of the whole, on completion, 800 francs, " au lieu de 961 fr." The culpable neglect of the publishers to give the dates of publication of the several fascicules has doubtless devolved upon many investigators, as upon the writer, much trouble and annoyance in ascertaining them, and to save to others similar trouble, a collation is here presented, the dates having chiefly been ascertained from Wagner's annual reports in the "Archiv fur Natur- geschichte." The appearance of successive fascicules has not been noticed in the " Bibliographic de la France." The titles of the respective monographs given below are those at the upper fourth of the first page of each monograph, and which are the only special titles' published. The work is more remarkable as a methodical repertory of facts respecting superficial osteological details, than as a digest exhibiting acute appreciation of the value and subordination of characters and their taxonomical application, or orthodox views respecting classification and the geological succession of 33 animals—the concurrent views of the most recent and approved investigators being the standard. The "genera," it must be remembered, are generally about equal in extent to the families now generally adopted.] COXTENTS. Tome premier [ Primates—Secundates | Avec atlas de 59 planches.
