GENUS PEDIOTHAGUS. 39 



Pediotragus Horstockii, uomen novum. 



Ears much shorter than in the foregoing species, slightly 

 longer than the horns. Horns without longitudinal furrows 

 or ribbs but with very inconspicuous basal rings and slightly 

 curved forwards. 



Hoofs elongated and slender, especially those of the 

 forelegs. 



I should say that the color on the whole and its dis- 

 tribution is about that of Pediotragus tragulus; the horse- 

 shoe-shaped marking on the crown of the head, however, 

 as well as the triangle on the nose are much darker colored 

 and therefore more pronounced : the white on the chin 

 occupies an elongated space not unlike a very long ellipsis. 



Length of ears about 11 cm., ditto of horns 10.2 cm.; 

 hoofs of fore legs: length above 2.9 — 3.5 cm., crown 1.7 cm. 



In the collection I recognize as belonging to this species 

 two adult males, one adult female (called rupestris by Tem- 

 minck, as I see on the stand) and a young ditto. The 

 females and one of the males are from v. Horstock's col- 

 lections (1823 and 1831), the second has been bought 

 at the sale of the old collection Van Lidth de Jeude in 

 1866: besides I prepared the skulls of Lidth de Jeude's 

 old male and Horstock's young female out of the skins: 

 four other skulls of adult specimens from Horstock's collec- 

 tions, two males and two females (one of the males with 

 broken off horn-cores) seem to belong to this species, although 

 one of the female skulls not without a note of interrogation, 

 as it is stronger built and stouter in all dimensions, but has 

 the nasalia so very short. Upper surface of skull of males 

 still rougher than in tragulus, of female nearly smooth.
