APES AND MONKEYS 141 



Guenons, the Mangabeys, the Gelada Baboons and the 

 Dog-Faced Baboons. 



Of the Guerezas, of which about a dozen species are 

 spread across tropical Africa, the best known is the 

 beautiful White-Tailed Guereza which is found at high 

 elevations in the forests of east central and east Africa. 

 It is clothed in a mantle of long, silky white hair, which 

 falls upon either side of its body, and contrasts with the 

 centre of the back and the head, which, except for a 

 white ring round the face, are glossy black. The tail is 

 long, bushy, and pure white. In former days, the skins 

 were favourite adornments of native warriors, and latter Jy 

 have been so much sought after by Europeans that the 

 species is now protected under the game regulations in 

 British territory. 



Another type, which has the latter third only of the 

 tail, white and bushy, and the rest black and short haired, 

 exists at lower elevations. 



The White-Tailed Guereza is found among the tops of 

 the tallest trees, preferably of those growing on the sides 

 of ravines and water-courses. It is useless to seek it 

 amongst the scrub and bush in the neighbourhood of 

 villages, for, being of all monkeys perhaps the most timid 

 and retiring, it keeps far away from the habitations of 

 man. It is entirely arboreal in its habits, and is seldom, 

 if ever, seen on the ground. To find it in its native 

 haunts in east Africa, the steps must be directed to the 

 heart of one of the great upland forests, where also dwell 

 the bongo and the giant hog. 



Leaving our camp at dawn, we breast a steep ascent 

 of maybe a thousand feet, and, the open or lightly-bushed 

 country spread like a map at our feet, find ourselves on 

 the highest terrace of the tableland, the region of un- 

 disturbed primeval forest.
