Probably the most abundant game mammal in eastern Africa, the 
hartebeest is better represented in the National Museum collection 
than are most of the species of antelopes. One species, Alcelaphus 
tora Gray, of which several geographical races have been described 
from Sudan, Abyssinia, and Somaliland, is, however, entirely unrep- 
resented. Another distinct species, Alcelaphus lichtensteini Peters, 
which occurs northward from Zambesi (the type locality) and Rho- 
desia into German East Africa, is represented only by specimens 
from south of the area included in the present report. This species 
has been made by Heller the type of a separate genus, Sigmoceros.' 
For measurements of specimens see pages 71-73.
