p. 65. 

 Type locality. "Coast of Guinea." West Africa. 

 Geogr. Distr. Sierra Leone ? Western Liberia ? West Africa. 

 Genl. Char. Hairs on head sparse, parted in center; chin hairs 

 brownish ; ears large ; region around eyes pale like face ; beard around 

 chin, short, thick. 



Color. Entire pelage black excepting a white patch on buttocks. 

 Measurements. "Height, 26 in. ; width of ear, 2 in. ; length of 

 body, 14 in. ; of arm, 14.6 in. ; of legs, 12 in. ; of hands, 3.8 in. ; feet, 

 4 in." Less., (1. c). Ex type. 



The above measurements show that the type of this species was 

 quite a young animal, probably not half grown. Its entirely pale face 

 causes it to differ from P. chimpanse, but it is impossible to determine 

 what species it really represents, as the young of many species of 

 Chimpanzees have white about the anal region, and the youth of the 

 specimen figured by Lesson presents no characters to separate it from 

 the young of other species. It may possibly be the young of P. chim- 

 panse. 



The skeleton described by Owen (1. c.) having been obtained in 

 Sierra Leone was probably an adult of this species. It does not appear 

 that the skin was preserved. The skull is peculiar in that the brain- 

 case is posterior to the face and not above it. The form of the brain- 

 case is a rounded ovate, and the skull is narrow and elongate ; quite a 

 different shape from the usual skull of Chimpanzees. 



The Simia pygmcea Schreber, founded upon Tyson's Pigmy is 

 quite undeterminable. The figure has face, ears, hands and feet flesh 

 color, no beard, and hair covering all the head and very short. Body
