Nearly a dozen species of ateles have been distinguished by naturalists, all bearing a close 
resemblance to each other. Most of them are found in the forests of Brazil and Guiana, and in 
the vicinity. The most remarkable of them are the Chameck, A. pentadact>/lus ; the A. paniscus, 
or Coaita of Buffon ; the A. ater ; A. marginatus ; the Marimonda, or A. Brissonii ; the A. mela- 
nocliir ; and A. hyhridus. 
Genus Si\.JOU, Cehus. — These creatures are somewhat smaller, bat less slender than the 
ateles : the tail is also less flexible. They are nimble in their movements and mild in their dispo- 
sition. They have a familiar yet unobtrusive curiosity. There are numerous species in the wilds 
of Brazil, Guiana, and Peru, all living in troops, and feeding on fruits, grain, emmets, birds'-eggs, 
&c. Many of them fall a prey to the ocelot and other felidaj. They are known under the various 
names of Sajous, Sapajous^ Weeping Monkeys, Musk Monkeys, &c. They are much used in 
Europe as well as in America by itinerant mnsicians, for climbing up to the windows to receive 
contributions. In France I have often seen them perform as mimic soldiers, ride upon dogs 
with the air of jockeys, and execute a thousand other tricks of the kind. This they did with a 
ludicrous calmness of manner, as if they actually regarded their drolleries as the most serious 
business in the world. 
A specimen of this monkey in the Garden of Plants, by the name Oi Jack, attracted much atten- 
tion by his intelligence. If nuts were given him, the shells of which he could not break with his 
teeth, he cracked them with a stone. One day as he sat aloft in his cage, some nuts were pre- 
sented to him, all of which he cracked with his teeth save one : this was so large he could not 
put it into his mouth ; so he began to descend in order to get a stone. On his Avay he met with 
■ a large nail sticking out of a post : he instantly struck the nut smartly against the nail and broke 
it. All this was done as if it was a matter of course. 
The most remarkable species of sajou besides the above are the following : The Brown Sajou, 
(7. apella, C. robustus, and C. variegatus, all of Brazil. The Tufted Capuchin, C. cirrifer, 
I of Guiana, C. vellerosus, C. frontatus, C. elegans, C. barhatus, C. flavus ; the Sai, or Weeper, 
a capucinuSj C. castaneus, C, versicolor, C. chrysopus, C. hypoleucus, arc found in various
