Anim., vol. 1, p. 246. 



Specimens. — Thirteen, from the following localities: 

 British East Africa: Agate's, Loita Plains, 3 (K. Roosevelt, 

 Heller); Engare Ndare River, 1 skull (Johnston); Laikipia, 2 (K. 

 Roosevelt); Lime Springs, Southern Guaso Nyiro, 2 (K. Roosevelt); 

 Loita Plains, 4 (Rainey) ; Nzoia River, Guas Ngishu Plateau, 1 skull 

 (White). 



The skull from the Guas Ngishu Plateau, I doubtfully place with 

 this form. It is so much larger than any skull of velox or of raineyi 

 m the collection that the difference m size can not be due entirely to 

 greater age, although it is from an animal miquestionably older than 

 any others in the series. With no sldtis from the Guas Ngishu coun- 

 try and no skulls of Acinonyx jubatus scejnmerlngii from Kordofan 

 for comparison, it seems best at present to consider it an extraordi- 

 narily large skull of velox. The distribution of this cheetah is given 

 by Roosevelt and Heller as "from the Rift Valley and Laikipia 

 Plateau westward over the highland country as far as the Nile low- 

 lands; north to the latitude of Nimule and south through German 

 East Africa." ^

Specimen. — One skin, as follows: 



Sudan: El Dueim, Wliito Nile (Meariis). 



This skin indicates a well-marked form, in which the spots are 

 much reduced in number and in size. The ground color of the upper- 

 parts is decidedly "pinkish-buff," much as in A. j. raineyi of the 

 British East African lowlands.
