blackish gray and livid yellow. The same structure is pre- 

 valent in the hair of the thighs, but there is very little 

 yellow, and all the rings are grey and white on the fore and 

 hinder paws. The internal facings of the limbs, belly, 

 chest, anterior covering of the shoulders, neck, and internal 

 facing of the tail, are white. The ears, palm of the four 

 hands, and face, are violet-black. The circle round the eyes 

 is of a livid flesh-colour, and some long, stiff, and black 

 hairs grow on the superciliary crest between the two eyes. 

 The original country of this monkey is unknown, but it is 

 probable that it came from Africa, like most of the other 

 Guenons. It is often brought to Europe, and has doubtless 

 been seen by naturalists, but not described, because it has 

 been confounded with the Callitrix. 



The Grivet possesses a similar disposition with the larger 

 Guenons. A male, of which F. Cuvier gives a figure, was 

 malicious and dangerous in its familiarity. A female of the 

 same species, on the contrary, always preserved its docility. 

 This last had been educated with great gentleness, and 

 never received any thing but caresses from its master. 

 Accordingly it acquired no small degree of confidence and 

 affection. 



This author remarks that this tendency to confidence, 

 this need as it were of affection, is almost universally cha- 

 racteristic of the female monkeys, but when it occurs among 

 the males may be considered an exception. He adds too, 

 that the opinion that this disposition is manifested more 

 towards men than women, is utterly unfounded. 



The size and proportions of the Grivet are similar to 

 those of the Callitrix and Malbrouc. 



The same writer describes another species called the 

 Vervet, differing little from the two last. 



The Mammalia in general, but more particularly the 

 Quadrumanous tribes, undergo such considerable changes 

 in the progress of their development, and the characteristic
