Specimens.—Thirty-nine, from localities as follows: 
British East Arrica: Juja Farm, Athi Plains, 4, including one 
skull and head skin, two odd skulls, and one mounted calf (Loring, 
T. Roosevelt, Cuninghame); Kamiti Farm, Athi Plains, 3, including 
two odd skulls (T. Roosevelt, Heller); Kapiti Plains, 10, including 
seven odd skulls (Loring, T. Roosevelt, Mearns); Kitanga, Athi 
Plains, 6, including one odd skull (T. Roosevelt, K. Roosevelt, 
Mearns) ; Nairobi, 1 skull (Mearns); Potha, Kapiti Plains, 4, including 
one odd skull (Loring, K. Roosevelt, Mearns); Ulukenia Hills, 10 
skulls (Loring); Ulu Station, 1 (Rainey). 
An adult male and female from Kapiti Plains; an adult female 
from Kitanga, Athi Plains; and a juvenile specimen from Juja Farm, 
Athi Plains, are mounted in the hartebeest group in the exhibition 
hall of African mammals. 
An old male of this hartebeest shot by Colonel Roosevelt on the 
Athi Plains, May 1, weighed 299 pounds. A younger male in better 
condition weighed 340 pounds and a female 315 pounds. 
Specimens of this subspecies average distinctly smaller than typical 
examples of the closely related Alcelaphus cokw kongoni from the 
Southern Guaso Nyiro, and the color of skins is slightly darker.
