The fur of C. brimnctis is rather coarse and has a length on 

 the back of about 4 cm. only. 



The length of the type spécimen from the upper lip to the anus 

 is about 67 cm , and the tail without hairs is subequal. The skin 

 of the other spécimen is about 67 cm. and the tail i cm. longer. 

 The tvpe is an adult maie with well developed crests on the head 

 and formidable tusks.

Two spécimens collected 80 km. east of Buta (n" 977""'^) must 

 be referred to this species as well, even if they may represent a 

 local aberration, or perhaps race. The main différence is that tbev 

 hâve a little longer fur, and that the colour of the back and flanks 

 more inclines to fawn, and the colour of the legs to a pale shade of 

 « dark fawn » (307.1). The tail is also darker than in the typical 

 briinneus. The ringing of the hairs is, however, very well visible, 

 especially on the lower back, and the gênerai resemblance with 

 brunneus apparent. From C. Ellioti they differ strikingly by the 

 colour of their legs. 



This brownish-looking Colobiis evidently succeeds C. Ellioti in 

 the Uele district. Matschie has given the name Colobus Schii- 

 botzi (') to a brown race with the lower side whitish. It is from a
