The belzebath may be easily distinguished by the following 

 description : Ateles belzebut ; atelocheirus supra nigery 

 allidus infra, palmis tetraductijUs. 



Observation. — ^The simia belzebut of Linnasus must not 

 be confounded with our belzebut, which is the same with 

 the ouarine of Buftbn. I propose giving to this species the 

 name of tha guariba, which it bears in the Brasils, or at 

 least in the work of Marcgrave, the only author who has 

 spoken of the visu. The carava of M. d'Azzara seems to 

 me to be diflcrent from it, as well as the alouati {simia seni^ 

 cuius). These three species will constitute the genus of 

 leapers (Jiurleurs). 



In the work of Marcgrave the figures of the guariba and 

 the exquima have been transposed. That placed opposite to 

 the description of the guariba, p. 226, represents the exqui- 

 ma, or the simia Diana of Linnsus ; and, vice versa, the 

 figure of the latter is placed opposite to the description of 

 the guariba. 



5. The camail. It is by this name that Buffon has de- 

 scribed the full-bottomed monkey of Pennant. I cannot 

 admit it among our ateles without caution ; for, if the de- 

 scription given of it by Pennant is correct, it does not belong 

 to them. Its name of camail and that oi pohjcomos (see the 

 Ulenchus c/iimaZ/u/raof Boddaert,) are given to it on account 

 of the long and thick hair which grows on its head hanging 



over
