44 THE SELOtJS COLLECTION. 



in the Collection represent one or more of these forms, but the 

 distinguishing characters are so very slight that it is impossible 

 when dealing with mounted heads only, and no exact localities, to 

 decide to which of these races or so-called races these specimens 

 belong. 



226 —19.7.15.251. 17 September, 1880. Hanyani River, 



Mashonaland, Southern Rhodesia.

 bique. 



230-231 —19.7.15.255-256. October, 1892. Between Lake Sungwe

DEFASSA, OK SING-SING. 



KOBTJS DEFASSA NZOIiE. 



Kohus defassa nzoiae, Matschie, Sitzber. Ges. nat. Freunde, 1910, p. 417. 



Size and horns much the same as in the Common Waterbuck ; 

 general colour rather richer and the elliptical white rump marking 

 replaced by a large white patch. A great many local races of 

 defassa have been described, but the distinguishing characters are 

 unsatisfactory ; and without large series of specimens from the 

 various type localities it is impossible to determine the exact 

 systematic value of such differences. 



Best horn measurements (No. 19. 7. 15. 258) : — length on 

 front curve 26| ; circumference 7| ; spread from tip to tip 18. 



Typical locality, Uasin Gishu Plateau, Kenya Colony. 



235-240 —19.7.15.257-262. Kenya Colony.
