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 Zodlogical Gardens at — 
Gizeh. Shortly after its arrival she had given birth to a young one.

Although troops of these monkeys are said to be frequently seen on — 
the Blue Nile and the Dinder, south of Singa, we met with them but | 
once, near Gozar on the latter river, where Dr. Phillips came upon two 
companies of them near the stream at midday. They rushed off over | 
the level ground and in a moment had disappeared among the scattered 
thorn trees. | 
It is worth noting that we met with no baboons, even among the | 
rocky foothills of the Abyssinian border near Fazogli. In the Zodlogi- 
cal Gardens at Gizeh, however, were some splendid specimens of the. 
dark-colored Anubis Baboon said to be from the Blue Nile. At the j 
mouth of the Dinder, where it meets the Blue Nile some forty miles if 
to the south of Wad Medani, is said to be a favorite resort for baboons. _
