Roosevelt Grant Gazelle 
Gazella granti roosevelti 
Native Names: Masai, olwargas; Kikuyu, ndaratari. 
Gazella granti roosevelti Heller, Smith. Misc. Coll., 1913, vol. 61, No. 7, p. 4. 
Range. —Typical of the elevated Athi Plains district 
ranging southeast to Makindu, north as far as the southern 
slopes of Kenia, and westward to the Rift Valley, where it 
extends as far north as the south shore of Lake Baringo. 
West of the Rift Valley of British East Africa, it is separated 
from robertsi by the Mau Escarpment, and farther south 
in the valley it merges, no doubt, into typical granti and 
eastward into serengetce on the northwestern slopes of Kili¬ 
manjaro. 
This race has been considered by sportsmen and nat¬ 
uralists as typical granti owing to the lack of specimens 
from the original locality in Ugogo for comparison of dif¬ 
ferences. The type specimen was shot by Colonel Roose¬ 
velt near Kitanga Farm, Mau Hills, Athi Plains, April 26, 
1909, and described recently by Heller as a new race. 
Others were shot in the same vicinity near Kapiti Station 
and near Kilima Kui, while other specimens were secured in 
the Rift Valley near Lakes Naivasha and Elmentaita. The 
Roosevelt Grant gazelle is nearest the typical granti of 
Ugogo, German East Africa, in color, but differs by its 
darker coloration and by the smaller and less wide-spread 
horns. From robertsi it differs by decidedly less widely 
spread horns and somewhat darker color in the males and 
further by the female being marked by a distinct dark flank 
band. From serengetce it differs by the wider and less 
divided white rump patch and considerably lighter body 
coloration. 
The dorsal color of the adult male is vinaceous-cinnamon 
paling toward the head and on the sides to pinkish-buff. 
The top of the rump and hinder border of the thighs is 
marked by a wide area of pure white which is continuous
