42 Report of the President 



collection of mammals from Borneo and north Burma, all of 

 the species represented being new to our collection and several 

 of them of special scientific importance. We are indebted to 

 Mr. Walter Winans for a series of specimens of the Wild Boar 

 from Germany, which have furnished the material for a group 

 of this interesting species, now nearly completed. We are also 

 indebted to the Honorable Theodore Roosevelt for two skins 

 of the White Rhinoceros. 



We have received nothing during the year from the 

 Museum's Stefansson-Anderson Arctic Expedition, nor from 

 the Congo Expedition under Messrs. Lang and Chapin, but 

 letters from the members of these expeditions indicate that 

 they have been very successful in their field work. Recent 

 letters from the Congo Expedition state that the collection of 

 mammals now numbers 2,400 specimens, and that the birds 

 collected number over 3,200 specimens. 



Mr. Carriker has continued his work in northern Venezuela 

 during the greater part of the year, and has sent to the Museum 

 nearly 250 specimens of mammals. 



Through arrangements made by Mr. R. C. Andrews, during 

 his visit to the Philippines and Japan in 1910, we have received 

 a complete specimen, skin and skeleton, of the Tamarau from 

 Mindoro, and a skeleton of the rare Berardius Whale from 

 Japan. 



One of the great events of the year was the expedition to 

 Lower California, under the direction of Dr. Charles H. 

 Townsend, and financed by Mr. Arthur Curtiss James. The 

 expedition resulted in the addition of nearly 300 mammals and 

 800 birds collected on the lower part of the Peninsula and 

 various adjacent islands. The mammals include four skins and 

 skulls and two complete skeletons of adult Elephant Seals 

 from Guadalupe Island, a species now on the verge of extinc- 

 tion. 



The greatest source of new material for both mammals and 

 birds has been the expedition organized by Mr. Chapman for 

 the exploration of western Colombia and neighboring parts of 

 South America. As noted in last year's report, Mr. W. B. 

 Richardson, who had formerly collected for the Museum in 

 Nicaragua, was sent to western Colombia in October, 1910,
