FURTHER NEW MAMMALS FROM BRITISH 



EAST AFRICA. 



BY WILFRED H. OSGOOD. 



Continued study of the Field Museum's collection of African 

 mammals, especially of the difificult Crocidurae, has resulted in the 

 conclusion that eleven further new species and subspecies should 

 be added to the rapidly growing list of the Mammalia of British East 

 Africa. With one exception, these have been compared with speci- 

 mens of allied forms in the British Natural History Museum. Types 

 and important specimens have been consulted also in the Academy 

 of Natural Sciences of Philadelphia and the United States National 

 Museum at Washington. It is a pleasure to acknowledge the cour- 

 tesies of the officials of these institutions.

 from the base of whiskers to and around eye; a slight buffiness just 

 below the black bordering the lower anterior half of the eye; posterior 

 cheeks below and in front of ear buffy; anterior cheeks below eye
