Revision Of The Mice Of The American Genus Peromyscus PDF Download

Excerpt from North American Fauna Sir: I have the honor to transmit for publication as North American Fauna No.28 a revision of the mice of the American genus Peromyscus, by Wilfred H.Osgood. The work consists of a systematic study of all the members of the genus, and includes keys for the identification of the various forms, together with the necessary illustrations, and maps showing the geographic distribution of the species. The mice of this group occur in great abundance throughout the United States, particularly in the Western States, but up to the present lime the interrelations and ranges of the various forms have not been worked out. Lack of this knowledge has been a source of embarrassment to workers in many parts of the country, particularly to the Biological Survey in its investigations of the geographic distribution and economic relations of American mammals. It is important, therefore, that a revision of the group be made available for general use. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
