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 light band on the forehead, and if this be present it is very 

 narrow. The whiskers, throat, and the under side and end of the tail are yellowish, 

 sometimes tending to orange ; and as in the last species, the base of the root of 

 the tail is grey. 



This monkey, of which we give a representation in the woodcut facing p. 97, 

 is closely allied to the grivet, from which it may be distinguished by the more 

 yellow-green hue of its upper parts, the yellowish 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 bears our climate well. Although 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 members of the group, it does not appear that the green 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 MOZAMBIQUE MONKEY (Cercopithecus rufoviridis). 



The guenons are 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 ferruginous red, but differs in the more yellowish-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-parts and the 

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



THE PAT AS MONKEY (Cercopithecus patasy 



The West African patas, or red monkey, from Senegambia, differs from all the 

 other members of this group of guenons yet 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 well 

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

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

 light grey 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 greyish-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 condition 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
