CYNOPITHECUS I. Geoff., Resum. Leg. Mamm., 1835, p. 16. Type 

 Cynocephalus niger Desmarest. 



Fur long, woolly ; head with hairy crest. Face, neck, hands and 

 feet, naked ; nose triangular, flattened behind nearly to the eyes ; upper 

 lip broad ; broad partition between nostrils directed downward and 

 outward ; cheek swellings distinct ; supra-orbital ridges conspicuous ; 

 cheek pouches large ; tail rudimentary. Braincase considerably 

 elevated above orbital ridge ; zygomatic arch straight ; orbital ridge with 

 but slight overhang; nasals tapering rapidly to a point posteriorly; 

 facial angle with outward curve ; molar series small. 



But little is known of the Black Ape of Celebes, and the material 

 contained in all the Museums, the specimens for the most part being 

 young animals, is not sufficient to permit a satisfactory decision as to 

 the number of species and their dispersion, to be reached. Herr 

 Matschie has recognized all the described forms and added to them five 

 more. His material, however, is totally inadequate for any satis- 

 factory opinion to be arrived at, consisting as it does, mainly of the 

 young animals from Zoological Gardens, in some cases, without 

 localities or data of any kind whatever. It is impossible, therefore, at 

 present to recognize these ; and the writer is not at all confident that in 

 accepting four of the species described by various authors, he has 

 not exceeded the limit of the distinct forms, and that some may be 

 found merely exhibiting a phase of pelage arising from age or sex, 

 of longer known species. Two genera of Monkeys exist in Celebes, 

 and their young are strikingly alike, and from them it is quite 

 impossible to tell what species each one may eventually represent.
