1873.] SIR V. BROOKE ON THE GENUS GAZELLA 549 



which is darkest on the neck, runs down the front of the fore and 

 outside of the hind extremities ; lateral bands wanting ; pygal 

 band blackish rufous, very thin and short. Ears moderate. Horns 

 in both sexes ; in the male very massive and rather short, strongly 

 annulated, the points projecting suddenly and boldly forwards. 

 Knee-brushes long. Height about 34". 



Hah. Senegal. 



Mr. Bennett was the first to point out the decided difference 

 between this and the species last described. Specimens of Gazella 

 mohr vary greatly, especially in the decision of the facial markings ; 

 but the much deeper shade and wider distribution of the red of the 

 upper parts of the body, running as it does the entire length along 

 the outside of the legs, and the much more massive and differently 

 curved horns of the present species, render it always easy to distin- 

 guish it fromGazella dama.

Hair smooth and short. Facial band blackish, slightly rufous be- 

 tween the horns ; light facial streak white, well marked ; dark 

 facial streak blackish, very definite, running through the eye and 

 leaving its upper end as a black spot isolated above it. A spot below 

 the eye, chin, throat, and a spot in front of the neck white ; lateral 

 bands wanting ; breast, belly, tail, and rump white, the white of 

 the latter encroaching into the sandy fawn-colour of the rest of the 

 body and the haunches. Knee-brushes well developed. Ears long, 

 bordered externally with black. Horns in the male lyrate, massive, 

 and strongly annulated, well developed but less massive in the 

 female. Height about 30". 



Hab. Abyssinian coast of the Red Sea, Danakil and Somali 

 countries, Berber, and East Senaar (Heuglin). 



This Gazelle, according to Blanford, inhabits bush and low acacia- 

 shrub-covered plains, never ascending the hills. They keep in large 

 flocks and appear to drink daily. The intensity of the facial mark- 

 ings vanes but is always remarkably strong in this species.
