NO. 2 MAMMALS FROM BRITISH liAST AFRICA — HOLLISTliR II 



FELIS LEO SABAKIENSIS Lonnberg 



Body skin and two skulls of adult males from the vicinity of 

 Nairobi. These skulls differ greatly from Abyssinian specimens, 

 and agree in general characters with specimens from the east coast. 

 They differ from skulls of massaiciis in all the minor particulars 

 mentioned by Dr. Lonnberg, and represent his recently described 

 race. A number of skins in Mr. White's possession vary consider- 

 ably in color, and the older males show much reddish brown and 

 black in the body color and mane, some being rather dark animals 

 on the whole. The skins of females and young males show faint 

 spotting below.
