Roosevelt Grant Gazelle 



Gazella granti roosevelti 



Native Names: Masai, olzvargas; Kikuyu, ndar atari. 



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
