Elliot in his Review of the Primates considers Sundevall's Otolincus 

 teng of the White Nile a synonym of this species. On the Blue Nile 

 it appears to be rare, but this is no doubt due in part to its retiring 

 habits. At Roseires we were shown one that had been caught by a 

 native soldier in gathering fuel among the larger trees near there. A 

 female from the same locality was living in the Zo5logical Gardens at

 mouth of the Dinder, where it meets the Blue Nile some forty miles 

 to the south of Wad Medani, is said to be a favorite resort for baboons. 

 In his book. Sport on the Blue Nile, (1903, p. 46) I. C. Johnson 

 mentions seeing great numbers at this point, but farther south they
