 and on forehead dark rufous and very long and

 tion). 



In 1907, Dr. Trouessart described his Cephalophus 

 natalensis vassei from Portuguese East Africa. Mr. 

 Wroughton, however, in 1911, showed that vassei 

 and robertsi were identical, and that the animal 

 described by Rothschild and Trouessart was only a 

 sub-species of C. natalensis. 



THE BLUE DUIKER 



(Cephalophus monticola} 



Ipiti of the Zulu tribes ; Iputi of Amaxosa ; Noumetje or 

 Gnometie of the Hottentots. 



THE Blue Duiker is known to the Natal colonists 

 by the Zulu name of Ipiti, which is pronounced Pete, 

 and to the Dutch colonists as the Blaauwbok or 

 Kleenebok. 



The Blue Duiker inhabits the bush-covered 

 portions of the country from about the district 

 of George in the Cape Province, eastwards to Zulu- 

 land. Local races or closely allied forms extend 

 through the forest regions of the greater part of 

 equatorial Africa.
