NEW RACES OF INSECTIVORES, BATS, AND LEMURS 

 FROM BRITISH EAST AFRICA 



By EDMUND HELLER 



NATURALIST, SMITHSONIAN AFRICAN EXPEDITION 



Further study of the collection of East African mammals in the 

 U. S. National Museum has resulted in the discovery of several new 

 races of insectivores, bats, and lemurs which are described in the 

 present paper. 



Nearly all of these new forms have been detected in the collection 

 recently made under the direction of Mr. Paul J. Rainey in British 

 East Africa. 



The new races described are chiefly from the summits of isolated 

 mountains situated either in the northern desert of British East 

 Africa near the Abyssinian border, or else in the Taru Desert near 

 the coast. 



The material has been compared directly with the types of the 

 described species in the British Museum. For the privilege of ex- 

 amining the specimens in the British Museum and for facilities in 

 the working out of the collection the writer is indebted to Mr. Old- 

 field Thomas, the curator of mammals.

 The last molar is distinctly larger than in either gallarum or nyasce.
