Size somewhat larger than in Madoqua ; females apparently 

 not bigger than males ; muzzle normal, with a small naked 

 area ; crown of head not tufted ; ears very large ; no face- 

 glands ; tail short ; hoofs short with pads on supporting 

 surface ; minute lateral hoofs present ; heel- tie in the form 

 of a double fold, of which the front one projects as a kind of 

 ridge ; horns of males longer than skull. Skull short and 

 broad, with relatively short nasals and long premaxillse, 

 small and shallow lachrymal pits, and inflated auditory 

 bullffi. 



The distribution is restricted to the mountains of Somali - 

 land and part of Abyssinia. 



Placed by Sclater and Thomas in the Aniilopinw, this 

 genus was associated with Madoqua as a separate subfamil}- 

 in 1910 by Pocock, who considers that the foot-glands are 

 essentially of the dik-dik type. A superficial resemblance 

 of the feet of the beira to those of goats and sheep is an 

 adaptation to a mountain life.
