Species and Subspecies of Mammals. 195 



The general appearance of this species is tliat of a yellowish 

 animal, with a brownish back and a reddish head and limbs, 

 and nnderparts whitish grey. This is the effect the various 

 colours of the hairs produce when glanced at. In coloration it 

 belongs to the light-hued baboons, of whicli section P.habuin 

 may be considered a representative. Looked at in certain 

 lights the hairs have a greenish-yellow tint, but when care- 

 fully examined the colours are as given in the description 

 and unlike any of the other species. Two specimens were 

 obtained by Sir H. H. Johnston in Nyasaland, ihe type at 

 Fort Johnston and the other at Zomba on Lake Nyasa. 

 The species bears no resemblance whatever to P. pruiaosus, 

 Thomas, also procured at Fort Johnston, either in colour or 

 in the characters of the skull.
