Tn the middle of January this year Mr. A. Sandberg 

 presented to the Natural History Museum a skin of a black 

 and white Colohus which appears to be new to acience 

 and hitherto undescribed. It belongs to the C. angolensis 

 group and I therefore venture to describe it under the 

 name of 



Colobus angolensis sandbergi. 



Unfortunately the hands and the face are missing, but 

 otherwise the skin is in good condition as the accompanying 

 figure proves. 



Pelage in general black and glossy, with a rather narrow 

 white måne at the shoulders which is very sparingly con- 

 nected with the broad white tufts in front of and below the 

 ears. The basal breadth of the white shoulder-patch is 

 contained fully 3 times in the distance from its posterior 

 börder to the root of the tail. There is no white super-
