few grey hairs. Ears large, somewhat smaller than in the Chim- 

 panzee, standing out laterally for the back." 



Hah. Gaboon ; called NscJiiego. 



Tho specimen received with the above name in the Museum was 

 in too bad a state to determine with accuracy if it is distinct from 

 T. niger. The baldness of the forehead appeared to be accidental. 



Dr. Franquct (Arch, du Mus. x. 18G2) described a black-faced 

 Chimpanzee as the T. tsehego ; but M. du Chaillu thinks it " only 

 an adult of T. niger, tho face of that animal being llcsh-coloured 

 when young and black when adult."

" It differs from T. calvus in wanting the baldness, the more 

 rounded face, the whiskers round the face, and less prominent muzzle, 

 the higher cheek-bones, and the moi'e hollow checks 



" Prom the adult T. niger in a rounder face, more prominent 

 cheek-bones, and more hollow checks ; larger cars, less prominent 

 muzzle, and the whiskers round the face. It has a different name 

 given to it by the natives, who call it Kooloo Kamba or Kooloo. 



" JIab. Ashankoo Mountains." 



It appears to bo probable that there are two species of Troglodytes 

 from the Gaboon. Gf the skulls in the British Museum received 

 from M. du Chaillu, one, the common, will rest erect when placed 

 on the lower jaw ; tho other is so much produced behind, or the 

 line of the lower jaw is so oblique, that it always falls backwards 

 when so placed ; but I cannot find that the latter belongs to T. 

 Kooloo Kamba.
