22 ANNUAL REPORT OF THE 



REPORT ON THE MAMMALS. 



By Outram Bangs. 



During the past year the Department of Mammals has received 

 upwards of three hundred specimens, mostly by gift. Two ex- 

 changes were made, one with Mr. E. R. Warren for a series of 

 mammals from Colorado, the second with the West Australian 

 Museum for a few Australian mammals. A most interesting and 

 important addition is the specimens collected in Sonora, Chihua- 

 hua, Lower California, Cerros, and Guadalupe Islands by W. W. 

 Brown, Jr., and presented by Mr. John E. Thayer. 



Specimens have been loaned Knud Andersen of the British 

 Museum, Walter L. Hahn of the Smithsonian Institution, and H. W. 

 Henshaw, E. W. Nelson, and W. H. Osgood of the Biological Sur- 

 vey, Washington.
