NATURAL HISTORY. 
reddish-yellow eyes. They sat gravely and silently in a group, and altogether presented a strange- 
spectacle. These red-faced Apes belonged to a species called by the Indians Vikarof, which is peculiar 
to the Ega district, and they had been obtained with great difficulty in the forests which cover the low 
lands, near the principal mouth of the J apura, about thirty miles from Ega. It was the first time I 
had seen this most curious of all the South American Monkeys. I afterwards made a journey to 
the district inhabited by it, but did not then succeed in obtaining specimens; before leaving the country, 
however, I acquired two individuals, one of which lived in my house for several weeks. 
“ The Scarlet-faced Monkey lives in forests which are inundated during a great part of the year. 
THE CQUXIQ. (From tlie Proceedings of the Zoological Society.) 
It is never known to descend to the ground ; the shortness of its tail is therefore no sign of terrestrial i 
habits, as it is in the Macaques and Baboons of the Old World. It differs a little from the typical 1 
Cebidse in its teeth, the incisors being oblique, and in the upper jaw converging, so as to leave a gap 
between the outermost and the canine teeth. Like the rest of its family, it differs from the Monkeys 
of the Old World, and from man, in having an additional grinding tooth (pre-molar) on each side of botli 
jaws, making the complete set thirty-six, instead of thirty-two, in number. This Uakari ( Brachyurus 
ccdvus), also called the White Uakari, from its skin, seems to be found in no other part of America than i 
the district just mentioned, namely, the banks of the Japura, near its principal mouth ; and even there 
it is confined, as far as I could learn, to the western side of the river. It lives in small troops amongst 
the crowns of the lofty trees, living on fruits of various kinds. Hunters say it is pretty nimble in its 
motions, but is not much given to leaping, preferring to run up and down the larger boughs in travelling 
from tree to tree. The mother, as in other species of the Monkey order, carries her young on her back. 
Individuals are obtained alive by shooting them with the blow - pipe, and arrows tipped with diluted 
Urari poison. They run a considerable distance after being pierced, and it requires an. experienced 
hunter to track them. He is considered the most expert who can keep pace with a wounded one, and
