466 A SPORTING TRIP THROUGH ABYSSINIA 



Oreotragus oreotragus (Zimm.). Klipspringer. 

 (Native name, "Alakud"; Somali name, " Sassa.") 



Zimmermann in 1783 described the klipspringer under the name of 

 Ajitilope oreotragus^ while, unfortunatel)-, Sir William Jardine employed 

 the term Oreotragus as a genus, adopting Boddaerts' specific name of 

 saltatrix. Now, as Oreotragus is thus the oldest generic and the oldest 

 specific name of the klipspringer, I, as a strict adherent to the rules of 

 priority in nomenclature, am obliged to call the klipspringer Oreotragus 

 oreotragus, in spite of my genuine disgust for the reduplication of terms in 

 scientific nomenclature. 



They were generally to be found in the cliffs of the river valleys and of 

 the high plateaux ; the last seen were in Simien, on Mount Buiheat. 

 Largest number noticed together, three. Also met with above Biya Kaboba. 



Cobus dcfassa (Riipp.). Abyssinian Waterbuck. 

 (Native name, '' Defassa.") 



This, the finest of the waterbucks, as regards size and length of horns, 

 was described by Riippell in 1835, but has been confounded very often 

 with Cobus ellipsiprymnus, the true waterbuck. It is found from German 

 East Africa in the south, to Kordofan and Sennar in the north. The 

 following are the species of waterbuck described : — 



Cobus ellipsipry limits. — South Africa from the Limpo])o northwards 

 through Nyassaland, and East Africa to South Somaliland.
