308 CLASS MAMMALIA. 



gant little animal found in Brazil, Cayenne, fyc. : at its full 

 growth it probably measures about a foot from the origin of 

 the tail to the extremity of the neck. The tail itself is longer. 

 The upper parts of the body are of a greenish yellow, 

 which turns to a greyish tint on the arms and thighs, and 

 a fine orange on the fore arms and legs. 



The tail greenish, excepting the end which is black. The 

 belly, breast, neck, cheeks, fyc. white, a little greenish spot 

 is found in the middle of the white of the cheeks. The 

 eyes are brown. The four hands are formed with great 

 exactness, the nails of the thumbs are fiat and large, and 

 those of the fingers are straight.

 without grasping them, and the tail may therefore be said 

 to be subprehensile. He used to sleep in a sitting pos- 

 ture with his head between his legs, which then touched 

 the ground ; when he handled a body with his fore feet, the 

 thumb was placed parallel to the other fingers ; it was only 

 in the hind feet that the thumb was opposable. 



His cry was a kind of hissing noise, with a gentle and 

 slender sound, which he would repeat three or four times, 

 for the purpose of expressing his anger, or his wishes. 



F. Cuvier gives a pleasing account of two Ouistitis or 

 striated monkeys and their little offspring born in the Mena- 

 gerie atParis, On the 27th of April, 1819, the female brought 

 three young ones, a male and two females. On coming 

 into the world their eyes were open, and they were covered 

 with hair of a deep gray, very smooth, and scarcely per- 

 ceptible on the tail. They instantly attached themselves to 

 the mother, embracing her closely and hiding themselves 

 in her fur. However, previously to their sucking, she ma- 

 naged to eat the head of one of them. The two others took
