BIBLIOGRAPHY OF NOETH AMERICAN MAMMALS. 



Prkpakkd by Tkkoiidiir Oii.l and Ellioti' Coiies. 



Several yeara have paased siDOe a Biblingrapby of Nnrtli American Haninials noa begun liy Dr. 

 Gill, and coutiniieil with tbe oooperutiou of Dr. Cones. Tlio design was to make it as complete as could 

 bo reasonably expected, and to include (a) all works and papers on Mammalia at large published in 

 North America, (A) all works and papers, wherever published, relating to North American MnmmaU, 

 nnd ((') such general works or collateral special papers as bear more or less directly npou the subject. 

 Pressure of other engagements upon eaob of the authors, however, obliged them to suspend the work in 

 IH74, and tbe material now published represents simply the progress tbey had made at that date toward 

 thii completion of their plan. The Bibliography is therefore not supposed to bo brought beyond 1874, 

 when systematic compilation of titles was abandoned, although a number of titles of later date bnvo 

 been collated by one of the anthors during bis preparation of the index-slips for tbe press. In the full- 

 est sense of tho term, this compilaticn is only " material " for a Bibliography ; tbe compilers ore fully cog- 

 nizant of its defects, and no criticism could be more severe than that which they ibemeelves would pass « 

 upon it. But even in its present state, the Bibliography is much more extensive than any hitherto 

 prepared ; it is published in connection with these Monographs of by far tho largest order nf Mammalia, 

 that tbe material which it represents may at length become available for all those who are working upon 

 North American Mammalogy ; and it is believed that it will be very useful to all who duly regard tho 

 purport of this explanot-ory note. 



The titles are arranged in chronological order under a few beads. The first set consiHtR of general 

 and miscellaneous publications on Mapimalsat large; the second of faunal publications, or those rolatiog 

 to the Mammals of particular geographical areas; while the remaining sets are those of orders or sub- 

 ordersof the Mammalio. Tbe Bibliography of American publications is believed to be very nearly complete 

 down to 1874 inclusive ; in other respects, the work is very imperfect. Many of the titles, especially the 

 foreign ones, are taken at second hand, and those which have not been verified may not be found to be 

 literally correct. Tbe titles of many of the general works are not given in full. 



A considerable part of the Bibliography — that relating to Eeveral of the families of tho Rodcn- 

 tla — baa already been presented on earlier pages of this volume, and such titles are not here duplicjited. 



In the labor of preparing this matter for the press, which has devolved upon Dr. Coues, much 

 assistance has been rendered by Mr. Allen, who has kindly revised the proofs, adding some tith'S, aud 

 making many valuable suggestions. Very great assistance has also been rendered by Mr. William Young, 

 the acuonipliahetl proof-reader of tbe Oovornmeut Printing Office, to whom special thanks are due for 

 bia valuable services in securing accurate typography, and in perfecting the arrangement of tb'!) titles.
