( 
a native of the western coast of Africa. Its common 
English designation of the White Eyelid is certainly 
both expressive and appropriate; for although 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 (except- 
ing only in the following species) has it a hue so 
perfectly dead-white or so strongly contrasted with the 
colour of the face. The latter was formerly regarded 
as a mere variety of the present; 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-colour, be- 
coming deep black on the lower part of the legs and 
on the hands. On the under part of the moustaches, 
which 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 
tapering towards the point, and generally tured back- 
wards 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 effect of which the peculiar expression of its physi- 
ognomy greatly contributes. It is generally good-tem- 
pered, and tolerably well-behaved, although not without 
its fair share of petulance and caprice. Our specimen 
is remarkably active, and exhibits its grimaces with 
laudable perseverance and unwearied zeal.
