Fur coarse and harsh. General colour dark brown or black. 

 Ehinarium naked, the naked part running upwards and backwards 

 in a wedge-shaped form on the top of the muzzle almost or quite to 

 tho level of the anterior canthus of the eye. Face blackish, but 

 the tips of the hairs, especially on the cheeks and snout, tipped with 

 dirty white ; a whitish patch round each eye. Ears rounded, pro- 

 jecting but little from the fur, their surfaces both outside and inside 



* The first part of this work, although dated 1827, must have appeared at 

 least as early as 1826, as it is quoted in that year both by Frederic CuTier and 

 Prince Maximilian von Wied.
