Nzoia River, Guas Ngishu Plateau, 9, including five odd skulls 
(T. Roosevelt, K. Roosevelt); Sirgoit, 30 miles south, 2 (T. Roose- 
velt). 
Writing of this form on the Guas Ngishu Plateau, Colonel Roose- 
velt says: ! 
These hartebeests, which are named after their discoverer, Governor Jackson, are 
totally different from the hartebeests of the Athi and Sotik countries, and are larger 
and finer in every way. One bull I shot weighed, in pieces, four hundred and seventy 
pounds. No allowance was made for the spilt blood, and inasmuch as he had been 
hallalled, I think his live weigbt would have been nearly four hundred and ninety 
pounds. He was a big, full-grown bull, but not of extraordinary size; later I killed 
much bigger ones, unusually fine specimens, which must have weighed well over 
five hundred pounds. * * * They were the common game of the plains. At 
times of course they were difficult to approach; but again and again, usually when 
we were riding, we came upon not only individuals but herds, down wind and in 
plain view, which permitted us to approach to within a hundred yards before they 
definitely took flight. Their motions look ungainly until they get into their full 
speed stride. They utter no sound save the usual hartebeest sneeze. 
Two adult males from a point 30 miles south of Sirgoit measured, 
respectively: Head and body, 1,820, 1,980; tail vertebrae, 590, 600; 
hind foot, 560, 590; ear from notch, 203, 207.

Specimens.—Two, from localities as follows: 
Britiso Kast Arrica: Meru Road, 30 miles northeast of Nyeri, 1 
(Rainey); Nyuki River, 1 (Rainey). 
Heller says that this subspecies of Alcelaphus lelwel is confined to 
the plateau region flanking Mount Kenia on the north and drained 
by the Northern Guaso Nyiro River. It ranges northward, he 
believes, to the southwestern slopes of the Loroghi Mountains. The 
type specimen, an adult male, measured in the flesh as follows: 
Head and body, 2,000; tail vertebra, 570; hind foot, 540; ear from 
notch, 180.
