Type in British Museum, no. 6. 2. 1. 1. 

 Tlie general appearance of this species is that of a reddish 

 monkey, quite diiferent in colouring from its paler relatives 

 of the C. centralis style. It is nearer to the animal from 

 Portuguese East Africa, which has been accepted as repre- 

 senting C rvfoviridis, but difl'ers from that species in its 

 pinkish-buff whiskers, throat, and general colour of the 

 under parts and in its jet-black hands and feet. 



A number of specimens from Fort Hall are in the British 

 ]\Iuseuni. Unfortunately there are no skulls of the C. a. 

 johnstoni specimens, so 1 can make no comparison between 

 it and the present species.
