this species than any of the other green Cercopitheci. In the next place, 

 the title of Faunus was not given to the animal itself, living or dead, 

 by Linnaeus, but to a figure by Clusius, which, though regarded by 

 BufFon, as that of his Malbrouck, is far from being proved to be so ; 

 indeed Mr. Bennett asserts, that, if correctly drawn, it represents a 

 species nearly related to the Diana. As, then, we do not know posi- 

 tively that the S. Faunus, is the Malbrouck, nor, indeed, what it is, we 

 receive it only as a doubtful synonym. 



GENERAL HISTORY. The Malbrouck is far less frequently brought 

 to Europe than others of the Cercopitheci more immediately allied to it. 

 We have only seen two living specimens in the menagerie of the Zoolo- 

 gical Society, London. 



In its disposition, this Monkey combines a certain degree of slug- 

 gishness, with a savage and vindictive temper ; but there is much dif- 

 ference in various individuals. One of the specimens in the menagerie of 

 the Zoological Society, London (an adult male), was gentle, familiar, and 

 pleased to be noticed, or caressed ; but, at the same time, it was neither 

 lively nor playful. The other was deceitful, and, though apparently 

 calm, very suspicious ; it was roused by the slightest provocation to 

 anger, and would turn upon its disturber, with the utmost malelvolence 

 depicted in its countenance, making every possible effort to assault him ; 

 exhibiting its teeth, and gazing fixedly in his face. One which Fred. 

 Cuvier notices, was extremely restless, and very active ; but it was also 

 sly and malicious. It would not make an open attack, but always 

 watched for an opportunity of springing unawares upon the object of its 

 hatred; it would then as suddenly fly from him, and effect its retreat; 

 then, again, make an unexpected assault, and so continue a system of 

 treacherous warfare, seizing every opportunity of gratifying its revenge 

 or malice. On the whole, indolence and ferocity form the character of 

 the adult, at least in captivity ; of their manners, in their native state of 

 freedom, nothing is known. 



Specimens, in the Leyden Museum, are said to have been brought 

 from Guinea.
