Rock Reedbucks 



Oreodorcas 



Oreodorcas Heller, 191 2, Smith. Misc. Coll., vol. 50, No. 8, p. 13; type 

 species Redunca Julvornfula. 



The rock reedbuck shows no striking external differences 

 from the true reedbucks with the exception of the much 

 shorter horns, the drab body color and the more bushy- 

 tail. The genus is based chiefly on the skull differences 

 which consist of smaller lachrymal-nasal sinus, larger orbit, 

 and the smaller size of the sphenoidal processes of the basi- 

 occipital bone. Oreodorcas has habits strikingly different 

 from the swamp or plains haunting reedbuck. It dwells 

 upon rocky hillsides and mountain slopes on the edge of 

 the plains country, in close proximity to the haunts of the 

 klipspringer. The genus includes a single species, fulvo- 

 rufula, which covers a wide range of country in the eastern 

 portion of Africa extending from Cape Colony north to 

 southern Abyssinia. Over this region it exhibits some geo- 

 graphic variation which has given rise to the recognition of 

 several races.
