is palish freckled grey, the top of the head and upper part of the back 

 having a general slight wash of olive green; the limbs, externally, are of a 

 fine freckled grey ; the whiskers are white, and of considerable length ; 

 they commence on the malar bones, and are increased by long hairs coming 

 from the throat ; their direction is upward and backward, so as partially 

 to conceal the ears ; and a white band traversing the forehead, merges 

 into the white of the whiskers, anteriorly to the ears ; the superciliary 

 bristles are long, black, and erect ; the under parts and inner sides of the 

 limbs are white ; the hands and feet are black ; the tail is largely black 

 at the tip, or all black ; beneath the tail, and about the callosities, the 

 hairs are brightly rust coloured ; the face is covered with black, long 

 hairs ; the general fur is full, long, and coarse ; the scrotum is of a 

 turquoise colour, or rich greenish blue ; the eyelids are of a pale flesh 

 colour ; the face and chin are black ; the ears are black ; the iris is hazle : 

 in its contour the body is robust, and the hands are long.

The Vervet is closely allied to the Malbrouck and Grivet, so that a 

 little care and attention are necessary to enable the observer to discriminate 

 between them. It differs, however, from both, in having the fur long, 

 and rather coarse, and of a much greyer tint, the wash of olive being less 

 decided ; in the tail being black, nearly throughout its whole length ; and in 

 the superciliary bristles being very conspicuous : from the Malbrouck 

 it may be distinguished by the muzzle being less thick and heavy, and 

 from the Grivet by the rust-red hairs on the space below the root of the tail. 



GENERAL HISTORY. Two fine adult specimens were lately living in 

 the menagerie of the Zoological Society, London. The female was 

 smaller than the male, but both had large sharp canines, and both were 

 intractable and malicious. They uttered a guttural, barking noise, when 

 irritated ; fixed an intense look upon the object of their displeasure ; dis- 

 played their teeth ; and took every opportunity of making a sudden attack. 

 It was dangerous to come very near to the cage in which they were con- 

 fined, unless due precaution was taken ; and, had they been at liberty, 

 the Author is convinced that, on more than one occasion, they would not 

 have hesitated to spring upon him ; yet no cause of offence had been 

 given. They seemed, indeed, to entertain capricious feelings of animosity 

 toward some persons, while toward others, if not gentle, they were 

 much more indifferent. Their ferocity (especially that of the male) was 

 equalled by their audacity; and their strength was such as to render them 

 sufficiently formidable. From the daring which they manifested, it 

 might be concluded that, in their native woods, the troops of this species
