Jackson's Hartebeest 157 



and torn neumanni, this one is certainly the largest and finest-looking beast, 

 and it can also lay claim to having, beyond dispute, the longest and ugliest 

 head of all of them. It is widely distributed and has a larger range than 

 its allies, being found from that part of Masailand between Lake Elmeteita 

 and Nakuru for about 40 miles north, and then right away west to the 

 Nile valley. It is also found farther east than the Masai valley, as 

 Mr. A. H. Neumann obtained it on the Laikepia plateau, west of the 

 Lorogi Mountains. 



This shows that its range runs more east and west, rather than north 

 and south. Until 1894 I thought that this species and B. cokei ran into 

 one another in the vicinity of Lakes Naivasha and Elmeteita, but I have 

 since found that this is not the case, as the extreme northern range of 

 B. cokei practically ends in the Kedong valley (I, however, once saw a 

 herd within about 6 miles of Naivasha), and B. jacksoni does not come 

 farther south than Lake Elmeteita. It is another, and lately-described 

 form, B. tora neumanni, that is found in the small circumscribed locality 

 in the vicinity of Nakuru and Elmeteita. And it is this beast, which is 

 an intermediate form between B. cokei and jacksoni, though quite distinct 

 and no longer, as was at one time supposed, a hybrid between the two, that 

 runs into B. jacksoni. In 1894, when going up country, I saw several 

 B. neumanni, but had no opportunity of going after them, though I was 

 struck at the time by their curiously shaped horns, and more particularly 

 by their remarkably white sterns. It was not, however, until three years 

 later that I managed to shoot a bull and two cows ; the bull and 

 one of the cows were actually feeding in company with two cow 

 'acksoni. The two species being seen together in the same herd 

 may be seized upon as an argument in favour of neumanni being only a 

 hybrid, but I am myself convinced that this is not so, but a totally 

 distinct species. I then had no more opportunities of going into the 

 question until on my way down country in August last year (1898),
