84 EINAR liONNBERQ, MAMMALS COLLECTED IN CENTRAL AFRICA. 



has somewhat larger horns than the type with a distance between the most distal points 

 of their outer convexity of 1185 mm. The palms are not quite as broad as in the type 

 being 260 mm. in a straight line. This bull is still in its prime with the molars not much 

 worn. Length of molar series 147 mm.

These measurements are almost all of them larger than those of a Buffalo bull 

 which I shot at Upper Guaso Nyiro in British East Africa, although that one was of the 

 same general type and also must be referred to B. c. radcUffei. The difference is no doubt 

 only due to the harder conditions of life for a big grazing animal in the dry country at 

 Guaso Nyiro than at Rutshuru. 



In their book »Life histories of African Game animals », Vol. I, Roosevelt and 

 Heller published a map (map 11 at p. 418) over the »distribution of the races of the 

 African Buffalo*. On this map the areas of distribution of the subspecies )>radcUffei» 

 and »cequinoctiaUs» are marked out. The western boundary line for the former race is 

 there drawn well to the east of Rutshuru River and excludes thus the Rutshuru plains 

 which are laid to the area of cequinoctialis. This is, however, evidently a mistake as the 

 present collections prove (cfr. also the figure 7). The Buffaloes of the Rutshuru plains 

 are true radcUffei. The horns of the skulls have a much more pronounced downward 

 sweep proximally than the photo appears to indicate. 



Damaliscus korrigum ugandse Blaine. 



Two very fine specimens, male and female, from Rutshuru 26th of June 1914, and 

 in addition to them a couple of skulls. 

 Both sexes are alike in colour.

The skulls of these specimens present an interesting feature with regard to their 

 first premolars. This tooth has namely at its anterior end an appendix attached (PI.
