This beautiful species of guenon is found on the banks of the 

 Ofoubour River, and in the mountainous regions of that country ; 

 it is one of the least common of the numerous species which in- 

 habit those immense forests. 



Otolicnus apicalis. The hair is very soft and woolly, mouse- 

 colored or slaty at base, tipped on the upper parts with various 

 shades of rufous, tinged with cinereous on the head, brightest and 

 with an orange tint on the back and upper part of tail ; dorsal 

 median line deep chestnut brown ; outside of limbs like back, 

 fading toward the feet ; below, mouse-colored, tinged, especially 

 on the interior of hind limbs, with yellowish white ; tail rufous

 It is found in the mountains of the interior, near the equator.
