MATERIAL 



FOR A 



BIBLIOGRAPHY OF NOETH AMERICAN MAMMALS. 



Prepared by Theodore Gill and Elliott Codes. 



Several years have passed since a Bibllograpby of North American Mammals was begnn by Dr. 

 Gill, and coutinned with the cooperation of Dr. Coues. The design was to make it as complete as could 

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

 North America, (6) all works and papers, wherever published, relating to North American Mammals, 

 and (d) such general works or collateral special papers as bear more or less directly upon the subject. 

 Pressure of other engagements upon each of the authors, however, obligeil them to suspend the work in 

 1874, and the material now published represents simply the progress they had made at that date toward 

 the oqnipletion of their plan. The Bibliogrephy is therefore not supposed to bo brought beyond 1874, 

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

 been collated by one of the authors daring his preparation of the index-slips for the press. In the full- 

 est sense of the term, this compilation is only " material " for a Bibliography ; the compilers are fully cog- 

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

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

 prepared ; it is published iu connection with these Monographs of by far the largest order of Mammalia, 

 that the 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 usefdl to all who duly regard the 

 purport of this explanatory note. 



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

 and miscellaneous publications on Mammals at large ; the second of fannal publications, or those relating 

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

 orders of the Mammalia. The Bibliography of American publications is believed to be very nearly complete 

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

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

 literallj correct. The titles of many of the general works are not given in full. 



A cousiderablo part of the Bibliography— that relating to several of the families of the Koden- 

 tio — has already been presented on earlier pages of this volnme, and such titles are not here duplicated. 



In the labor of preparing this matter for the press, which has devolved uiH>n Dr. Coues, mnch 

 assistance has been rendered by Mr. Allen, who has kindly revised the proofs, adding some titles, and 

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

 the occoniplished proof-reader of the Government Printing Office, to whom special thanks arc due for 

 his valuable services iu securing accurate typography, and in perfecting the arrangement of the titles.
