 of it :— 



Cercopithecus denti Thos.* (Plate I.) 



Abstr. P. Z. S. 1907, p. 1 (Jan. 22, 1907). 



A member of the camphelli-mona group, but not darkened on 

 the posterior back and hind limbs, and with a very sharply con- 

 trasted white belly. 



Upper surface of head and neck olive-grey, the visual light frontal 

 band present but not conspicuous. Back dark grizzled chestnut- 

 brown (nearest to "burnt-umber" of Ridgway) ; colour of rump 

 not darker, but, on the contrary, passing gradually into the 

 paler tone of the hips and hind legs. Under surface from chin 

 to anus, and inner sides of limbs to wrists and ankles, clear 

 creamy-white, very sharply defined from the darker colour, not 

 only on the limbs, as in camphelli and others, but also along the 

 flanks, where the white rises nearly halfway up the lateral aspect 

 of the animal. Ears with short yellowish tufts rising from their 

 inner surfaces. Outer sides of fore limbs deep black from 

 elbows. Hind limbs grizzled yellowish olive, lighter than the 

 back, down to and including the ankles, the metatarsals and toes 

 black. Tail indistinctly blackish above at base, then dull greyish 

 white for two-thirds its length, darkening again to black on its 

 terminal third.
