So far as one can judge from the descriptions, ami from an 

 examination of the types of punctulatus and whitfieldi, all the 

 names included in the above synonymy refer to C. maxwelli 

 as defined in this paper. 



This species is characterized by its moderate size; uniform 

 ungrizzled dorsal pelage, the colour being dusky in adults, 

 brighter in the young ; the whitish hairs lining the ears not 

 forming a conspicuous fringe; normal nasals ; and, above all, 

 by the relatively large horns present in both sexes; in female, 

 horns a little less developed than in male. 



The type-locality is " Sierra Leone," and the range extends 

 from Senegal and Portuguese Guinea southwards through 

 Sierra Leone.
