Jackson Lelwel Hartebeest 



Bubalis lelwel jacksoni 



Native Names: Nandi, chemnyokoso ; Turkana, etulia. 

 Bubalis jacksoni Thomas, 1892, Ann. y Mag. Nat. Hist., p. 386. 



Range. — Plateau region of Mount Elgon and the Mau 

 Escarpment from the Lumbwa country northward beyond 

 the headwaters of the Turkwell River. 



Jackson discovered the hartebeest which now bears his 

 name on his Initial journey to Uganda in 1889. Until very 

 recently the name was applied broadly by sportsmen to 

 all the hartebeests of the lelwel type found in Uganda and 

 the Nile Valley. The Jackson hartebeest, however, is a 

 distinct race occupying the highland region of the Mau 

 and Mount Elgon. It is a darker and richer red than any 

 other race and somewhat smaller In size than the Nile 

 races. The color is quite uniform cinnamon-rufous with- 

 out any black markings on the legs or face. The only 

 contrasts in its coloration are the black chin and terminal 

 tuft of the tail and the white hair lining the inner side of 

 the ears. 



A large series of specimens Is in the National Musuem, 

 from the Uasin Gishu Plateau, collected by the Roosevelt 

 expedition. The flesh measurements of one of the adult 

 male specimens were: head and body, 72 Inches; tail, 23^ 

 inches; hind foot, 23 >^ inches; ear, %% inches. An aver- 

 age male skull measures In length 20 inches, that of a 

 female i8>^ inches. The horn length averages about 22 

 inches. Great variation In the spread at the tips is shown 

 in the series, which ranges from 4 to 14 inches in this meas- 

 urement. Such variation is due to the wide diversity in 

 direction taken by the horns near their tips. As a rule, 

 however, the points extend parallel after making the final 

 turn backward at right angles to the dorsal plane of the 

 head. Ward's record horn length for this race Is 26 inches. 

 The longest specimen in the National Museum series is 

 23^^ Inches in length.
