RUFOUS GAZELLE 259 



Abyssinian side of the Bahr-el-Gebel, ranging from Gondokoro in 

 Uganda to Bor in the Sudan. 



THE RUFOUS GAZELLE 



{Gazella rufina) 

 (Plate ix, fig. 10) 



This gazelle was described by Mr. O. Thomas in the Proceedings 

 of the Zoological Society for 1894, p. 468, on the evidence of a flat 

 skin purchased by Sir E. G. Loder in Algiers, which appears to be 

 the only known specimen. 



It is described as very similar in colouring to rufifrons, but of 

 much larger size (shoulder-height about 30 inches), with the light 

 streaks on the face indistinct, and with a heavier skull and stouter 

 hoofs. Possibly it is only a race of rufifrons. 



The general colour of the coat is bright rich rufous above, with 

 the central face-streak especially rich, approaching chestnut, but the 

 light streaks on each side of it only slightly paler than the general 

 body-colour, and thus markedly different from those of most other 

 species. The crown of the head, cheeks, and sides of the neck are 

 pale rufous. The dark flank-band, although less than a couple of 

 inches in depth, is well defined and nearly black ; the light band is 

 equally distinct from the dark rufous of the back, being about the 

 same colour as the neck ; but the dark border to the rump-patch is 

 but slightly developed. The tail is rufous at the base, with a black 

 tip. As in rufifrons, distinct knee-tufts are lacking. The hoofs are 

 twice the bulk of those of rufifrons ; and the horns are relatively short, 

 and ringed for two-thirds their length, with the tips bent inwards. 



THOMSON'S GAZELLE 



{Gazella tJiovisoni) 



Siualla, SwAlilLi ; Engoli, Masai 



(Plate x, fig. i) 



Although not larger than tilonura (from about 25 to 27 inches 

 at the shoulder), Thomson's gazelle, on account of the long horns of 

 the bucks, and the broad black flank-band of both sexes, is one of 

 the handsomest members of the whole group. The horns are of the
