DESCRIPTION. Description of a specimen (No. 42, Cat. Mamm. 1838) 

 in the museum of the Zoological Society, London : The general colour is 

 grey ; the top of the head and back are washed with olive, the hairs 

 being annulated with black and yellow ; a white band crosses the fore- 

 head and joins the white whiskers, which consist of long hairs directed 

 backward, and spreading so as to conceal the ears ; the under surface, and 

 inside of the limbs, are white ; the tail is black, intermixed with grey hairs 

 above, passing into white at the termination ; the hands and feet are dusky 

 black ; the face is black, becoming livid around the eyes, an angle of 

 black facial hairs pointing behind them, to the ears ; the ears and palms 

 are black ; scrotum, of a turquoise colour, surrounded with long white 

 hairs ; the hands are short and small.

In general form the Grivet approaches the Malbrouck, its head, how- 

 ever, is less rounded, and the muzzle less thick ; a triangular mark of 

 black hairs behind each eye points to the top of the ears ; and the whiskers, 

 instead of being short, form full and long cheek-tufts. The ears, also, are 

 smaller in proportion. From the Green Monkey it may at once be 

 distinguished by its greyer hue, by the white frontal band, the white 

 colour of the whiskers, and by the grey termination of the tail. 



GENERAL HISTORY. The disposition of the Grivet is similar to that 

 -of the Green Monkey ; but of its habits in a state of nature nothing is 

 ascertained. 



Our first knowledge of the species is due to Fred. Cuvier, who figured 

 it in his Mammalogie, under the title of Grivet. Riippell informs us that 

 it is common in the low lands of Abyssinia, in Sennaar, and Kordofan, to 

 an elevation of 4,000 feet above the sea. It is called Tota in Abyssinia, 

 and Abellan in Sennaar and Egypt.
