98 APES AND MONKEYS. 



of the head, the hands, feet, and the upper part of the root of the tail being blacker. 

 There is generally no hght band on the forehead, and if -this be present it is very 

 narrow. The whiskei-s, ttroat, and the under side and end of the tail are yelloAvish, 

 sometime.s tending to orange ; and as in the last species, the base of the root of 

 the tail Ls grey. 



Tins monkej', of which we give a representation in the woodcut facing p. 97, 

 is closely allied to the gi-ivet, from which it may be distinguished by the more 

 yellow-green hue of its upper parts, the j'eUowish whiskers, and the general 

 absence of the white band on the forehead 



The green monkey is about the size of a large cat, the length of the head 

 and body being 16 or 18 inches, and that of the tail rather more. It is one 

 of the hardiest of the guenons, on which account it is so frequently seen in con- 

 finement, as it beai-s our climate well. Althougli gay and gentle during youth, it 

 usually becomes morose and vicious when old, and is therefore not one of the 

 species usually selected for exhibition by travelling organ-grinders. Like the 

 other membei-s of the group, it does not appear that the gi-een monkey ever utters 

 a sound when in captivity, and from an early account of the species it appears to 

 be similarly silent in its wild condition. 



The Mozajibique Moxkey (Cercopitheeiis rufoviridis). 



The guenons ai'e also represented in the Mozambique and Zambesi districts of 

 the East Coast, although far less abundantly than on the West Coast. The 

 Mozambique monkey agrees with the vervet in having the root of the tail and 

 adjacent regions of a ferniginous red, but diflfei-s in the more j-ellowish-grey tint 

 of the fur of the upper parts, which tends to a blacker hue on the crown of the 

 head, the tail, and the outer sides of the limbs ; while the under-pai-ts and the 

 inner sides of the limbs are pure white, instead of reddish-wliite. 



The Patas Moxkey (ferco2>i</iecifcs^xttas).^ 



The West African patas, or red monkey, from Senegambia, difFei-s from all the 

 other membere of this group of guenons j'et noticed by the red colour of the fur of 

 the greater part of the body ; the nose, an arched band on the forehead, and the 

 outer surfaces of the arms being blackish. The reader will, therefore, have no 

 difficulty in recognising this species whenever he meets with it, and it is weU 

 represented in the accompanying figure. In addition to these leading features, we 

 may notice that beneath the large and blackish eara there are thick bushy tufts of 

 light grej- hair, which extend forwards on to the cheeks and lower jaw, so as to 

 cause the naked part of the face to be limited to a narrow space between the eyes 

 and the upper lip. From these tufts the grejash-coloured hair is continued on the 

 whole of the under surface of the body, as well as on the inner sides of the limbs. 

 The hands are of a dusky brown colour, with very short fingers, and the thumb is 

 reduced almost to the conchtion of a tubercle. The animal is about the same size as 

 the green monkey. The black of the nose continuing upwards to the arched band of 



* Frequently known as Cercopithecus ruber.
