Like many other characteristic animals of North-eastern Africa, the present 
Antelope was one of the discoveries of the great explorer and naturalist 
Riippell, who first described it in his volume upon new Mammals from 
Abyssinia which contained the results of his long investigations in that 
country. Rippell called this species “ decula,” from the Latin transliteration 
of its Amharic native name, remarking at the same time that this word must 
not be confounded with “ thecula,” which is the Abyssinian name for the 
Hunting-dog (Lycaon pictus). He remarks that the species belongs to the 
subgenus Tragelaphus of Blainville, and is closely allied to 7. sylvaticus of 
the Cape, from which it is distinguishable by its smaller size and different 
colouring. Riippell obtained a good series of this Antelope, and gives 
excellent descriptions of the adult male, the adult female, the two-year-old 
male, and the newly-born calf. He met with it in the bushy valleys of Central 
Abyssinia, round the lake of Dembea or Tana, where it feeds principally on 
small leaves of trees, and is said to be specially fond of the ripe fallen fruits
