Most of the known specimens of the East African bongo were pur- 
chased from natives and are therefore without definite history as to 
exact locality and other information. The National Museum is 
fortunate in possessing three specimens, a male, female, and young, 
killed by white hunters and with complete data.

Specimens.—Kight, from localities as follows: 
British East Arrica: Enjoro, Mau Forest, 2 (K. Roosevelt) ; 
Mau Escarpment, 5 (White, Ross, McMillan); near Nakuro, Mau 
Forest, 1 (Grey). 
The two specimens, female and young, shot by Kermit Roosevelt 
at Enjoro, and the old male shot by George Grey and presented by 
him to the collection of the Smithsonian African Expedition, through 
Col. Theodore Roosevelt, are complete specimens with skulls. The 
skull of the young animal shows the milk dentition. The five skins 
presented by John Jay White, W. N. McMillan, and Maj. C. J. Ross 
were all purchased from natives, but were said to come from the 
forests of the Mau Escarpment. The skins all vary remarkably in 
the number and width of the lateral body stripes. These range from 
from 10 to 14 in number, and in only three skins are alike in number 
on right and left side. Some of the skins have the stripes broad 
while in others the stripes are very narrow. There is likewise great
