DESCRIPTION OF A NEW vSUBSPECIES OF AFRia\N 

 MONKEY OF THE GENUS CERCOPITHECUS 



By D. G. ELLIOT 



The species of monkey here described was obtained by the Smith- 

 sonian African Expedition in British East Africa, in 1910, and I 

 am indebted to the authorities of the U. S. National Museum for 

 the privilege of making it known to naturalists.

This species is somewhat similar to C. c. johnstoni, from the south 

 side of Mount Kilmanjaro, but differs altogether in its buff under- 

 parts and inner side of limbs, thus contrasting strongly with the 

 yellowish white of C. centralis and the grayish white of C. c. johns- 

 toni and C. c. u'hytei. Two examples, both young adults, females, 

 were in the collection.
