38 THE SPECIES OF THE ANTELOPE- 



passu with the external ones, as will be understood froDi 

 my descriptions and measurements of these bony parts. 



Pediotragus tragulus (Forster). 



The rarity in collections may be the reason why it nearly 

 always has been confounded with the following species. 



Ears very large, much larger than the horns, in size equal- 

 ling about the distance between their base and the end of 

 the muzzle. Horns without every trace of basal rings, longi- 

 tudinally furrowed and ribbed ; they are practically vertical. 



Hoofs short and high, especially those of the fore legs. 



Color of the head of a brighter rufous than of the rest 

 of the body. The horseshoe-shaped marking on the crown 

 of the head and the triangle on the nose very inconspi- 

 cuous, especially the latter. Under parts of body white; 

 of the same color is a rather small stripe on the inside of 

 the upperhalf of the fore legs and a ditto inside the thighs. 

 Buttocks white, but not so round the anus. Above the 

 eye a halfmoon-shaped white stripe. Lower jaw and a 

 triangle on the chin white. 



The here described adult male has been collected in the 

 Cape Colony by Mr. de Lalande. Length of the ears about 

 16 cm. (6.4 inches), of the horns 11.5 cm. (4.6 inches); 

 hoofs of fore legs: length above 2.5 cm. (1 inch), crown 

 2 cm. (0.9 inches). The skull is not in the stufied skin : 

 we possess however another skull of an adult male and 

 of which the longitudinally ribbed horns prove clearly that it 

 belonged once to a specimen of our species. I give here some 

 figures of its measurements. The premaxillaria are wanting. 



Upper surface very roughened. Coronoid process of man- 

 dible shorter than in the following species: mm.
