Cercopithecus aivtitans Liiiii. 

 (From a specimen living in tlie Society's (Tiivik-iis.) 



Mr. Bates also obtained examples from Efulen in the Bulu 

 Country, Cameroons, 1500 ft. alt. These differ from the Benito 

 River examples in having the haii'S on the foi-e part of the throat 

 and on the posterior part of the abdomen washed with brown. 

 I do not know whether this difference in tint has any systematic 

 value, or whether it is due to artificial staining of the haii' during 

 the preparation of the skins. The measui-ements of two are as 

 follows : — 



1. 2 . Head and body 530 mm., tail 800 mm. 



2. 9 540 „ „ 750 „
