Horns. Apparently longer than in defassa. Very straight, 

 onlv bent forward at the tips, and much laid backwards as a 

 whole.

This waterbuck is nearly allied to K. u. defassa, from 

 which it is easily distinguished by the shape of its brain- 

 case. Although some specimens are darker than the one 

 described. A", u. tschadensis is always much duller-coloured 

 tlian the Senegaml ian K. u. unctuosus, from which it also 

 differs in its miich longer horns and larger size.

Decidedl,' intermediate in size and shape of skull and horns 

 between the Gold Coast buffalo and the dwarf races of the 

 Congo forest. 



SkuH. kSliorter and broader than in the Gold Coast form. 

 Nasals relatively longer and narrower. Orbits strongly 

 projecting. Horns: |)alm distinctly edged, sligiitly directed 

 backwards and slightly depending, rather thick, but without 

 boss at base ; the tips are rather abruptly compressed, 

 sharply set off from the palm ; they are short and directed 

 backwards. 



JJimensions of type skull. Basal length 390 mm. ; palatal 

 length 228 ; postorbital width 215 ; mastoid width 208 ; 

 length of nasals 166 ; lengtli of horns along outer curve 530 ; 

 breadth of palm at base 130 ; distance of horns at base : 

 proiimally 53, distally 125 ; greatest width of horns 540, 

 distance of tips 385. 



From the Gold Coast buffalo B. c. diehli differs by its 

 smaller size and projecting orbits. On the other hand, it 

 is much larger than B. c. nanus, whose horns have longer 

 tips and arc more strongly recurved. 



Only the iikull of this interesting race has been examined.
