Face and ears nude and black. The trunk generally, above and below, brownish 

 black, or tinged below with greyish. Arms and legs greyish externally on their 

 radial and tibial portions. Tail short and stumpy. 



Inhabits Celebes.-^ 



Length of body from muzzle to root of tail 1 foot 6 inches ; length of tail 

 1 inch. 



There are the remains of a skeleton of this species in the British Museum, 

 but they are so fragmentary that little or no information can be derived from them. 

 They belong to an individual that lived in the Zoological Society's Gardens some 

 years ago ; and it is interesting to observe that the pelvis manifests the same type 

 of deformity as that which has been described by Dr. Murie as characteristic of the 

 normal pelvis of M. cyclopis. 



1 Confined to this island and to the Philippines and the small ueighhouring island of Batchian is the following 

 remarkable genus Cynopithecus, generally regarded as sub-generic to the African genus Cynocephalus.

^ General colour, deep, dull-black. The tail is excessively small, being reduced to a mere tubercle, or to only a faint 

 indication externally of its existence. The vertex is surmounted by a crest of long hairs, which droop somewhat over 

 the occiput. The face is blackish, and the lips and callosities are livid fleshy. The body is short, and the limbs 

 rather long. 



Length of body 1 foot 9 inches. 



Inhabits Celebes and Philippines. 

 The occurrence of this ape in the Australo-Malayan region, with its strong affinities to the African Cynoeephali 

 and its structural isolation, so to speak, from all the south-eastern Asiatic forms, or those distinctive of the 

 Indo-Malayan region, are facts most difficult of explanation, but of great interest in geographical distribution.
