MR. O. THOMAS ON GAZELLES FROM ALGERIA. [June 5, 



by its much larger size, heavier skull, stouter hoofs, and by the 

 indistinctness of the light facial bands. 



The general colour is a bright rich rufous, very different to the 

 pallor of G. loderi. The central facial band is especially rich, 

 almost approaching chestnut, while the light bands on each side 

 of it, although distinguishable, are only slightly paler than the 

 general body-colour, contrasting markedly with the white and 

 prominent corresponding bands in other species. Crown, cheeks, 

 and sides of neck pale rufous. Ears proportionally rather short, 

 their exterior surfaces rufous, similar to the body in general ; their 

 edges and inner surfaces whitish. Dark lateral bands very strong 

 and well-defined, although narrow (1 to Ig inch broad), nearly 

 black ; light lateral bands sharply defined from the deep colour of 

 the middle back, concolorous with the neck, cheeks, and crown. 

 Dark pygal band but little developed. Belly w bite. Limbs rufous 

 in front, whitish behind ; knees w ithout tufts, but with a narrow 

 ridge of rufous hairs running down the metacarpus just below the 

 knee. Hoofs large and heavy, twice the bulk of those of G. rufi- 

 frons. Tail rufous basally, black terminally. 



Skull (tig. 1) stout and heavily built, with short broad nasals, 

 large and widely open anterior nares, broad heavy muzzle, and 

 large teeth. 



Eig. 1. 



Skull of Gazella rufina. 



Horns unusually short in proportion to the general size, those 

 of the fype, ■which is unquestionably full-grown, less than once
