438 HISTORY OF 



The fourth of this kind is the mangabey ; it may be distin- 

 guished from all Qthers by its eye-lids, which are naked, and of 

 a striking whiteness. It is a native of Madagascar. • 



* This Monkey was called by Buffon the Mangabey from an erroneous 

 idea that his specimens were obtained from the territory of that name in the 

 Island of Madagascar : it appears, however, more probable that it is a native 

 of the western coast of Africa. Its common English designation of the 

 White Eyelid is certainly both expressive and appropriate ; for althon.Tli 

 many others of the tribe, more especially among the Baboons, have the 

 same remarkable absence of colouring matter in the skin of their upper 

 eyelids, yet in none (excepting only in the following species) has it a hue so 

 perfectly dead-wliite or so strongly contrasted with the colour of the face. 

 The latter was formerly regarded as a mere variety of the present j but the 

 distinctions between them appear to be permanent and are quite sufficient 

 to justify their separation. 



In the animal now under consideration the head, the whole of the upper 

 surface and sides of the body, the tail, and the outsides of the limbs, are of 

 one uniform deep grayish black, or more properly soot-coloiu-, becoming 

 deep black on the lower part of the legs and on the hands. On the under 

 part of the moustaches, wliich are bushy, spreading and directed backwards, 

 the fore part of the chest, the under surface of the body, and the inside of 

 the limbs, the general colour is of a light gray with only a slight mixture of 

 a dusky hue. The fingers are long and slender ; the ears rather small and 

 blackish ; and the whole face livid, with a blacker tinge round the eyes, and 

 on the nose, lips, and chin. The tail is thick and cylindrical, scarcely taper- 

 ing towards the point, and generally turned backwards over the body, which 

 it exceeds in length. 



This species is not destitute of intelligence, and is easily taught to perform 

 a variety of antic tricks, to the eflect of wliich the peculiar expression of 

 its physiognomy greatly contributes. It is generally good tempered, and 

 tolerably well-behaved, although not witliout its fair share of petulance 

 and caprice. 



The Collared White Eyelid Monkey.— The CoUared differs from the Com. 

 raon Wliite Eyelid Monkey principally in the deep chestnut brown of the 

 upper surface of its head, and in the colliir of pure white crossing the fore 

 part of its neck and including the large bushy moustaches which extend 

 forwards upon the cheeks and pass backwards beneath and behind the ears. 

 The rest of the upper surface of the body is of the same slaty or soot-colour- 

 ed hue as that of the former ; the hands, face, and ears have nearly the same 

 (iflge ; and the under surface is equally of a light ashy gray. Its form and 

 proportions are similar, except that it is somewhat smaller. Tlie legs are 

 equally slender, and the taU equally long and tliick. Tlie hair which covers 

 the body is also, as in the preceding species, long and soft to the touch. A 

 remarkable character in the dentition of both, rendered particulary obvioul 

 by the taste for grinning in wliich these animals are so prone to indulge 

 consists in the great breadth of the two middle incisors of the upper jaw. 

 It is this character, wliich, together with the prominence of their canina 

 teeth, produces that greater extension of muzzle on which their generic 

 distinction has been chiefly founded.
