 Lake Eudolf district, but differing by its lighter body- 

 coloration and narrower or less broadly bracket-shaped 

 horns ; similar to cokei in size and general body-colour, but 

 feet with a black band bordering hoof-clefts, and horns 

 narrower and less bracket-shaped." 



In a later paragraph it is stated that these hartebeests 

 have the horns less widely spread than those of neumanni, 

 and " more or less intermediate between those of cokei and 

 jacksoni in shape, and on this account they have usually been 

 considered hybrids between those species by sportsmen. 

 This, however, is not the case, although they occupy a 

 somewhat intermediate geographical position. They are 

 found on the north-western edge of the range of cokei, and 

 they are really surrounded by this species and actually 

 removed by many miles from the nearest jacksoni. The 

 Nakuru race is known only by a single herd, which inhabits 

 the country lying between Lakes Nakuru and Elmentaita. 

 From neumanni, which occupies the region bordering the
