the breast, and from that moment, the mother bestowed on 

 them the natural attention of a parent, and her cares were 

 shared by the father. Every thing that Edwards reports 

 concerning a couple of these animals which produced in 

 Portugal is confirmed by M. F. Cuvier. When the female 

 was fatigued in carrying the little ones, she would approach 

 the male, send forth a little plaintive cry, and immediately 

 the latter would take them with his hands, place them 

 under his belly, or upon his back, where they would hold 

 fast of themselves, and thus he would carry them about, 

 until the want of sucking rendered them uneasy. Then he 

 would return them to the mother, who got rid of them 

 again as soon as possible. It was upon him, indeed, that the 

 principal burden of their care seemed most generally to 

 fall. The mother did not evince for them that degree of 

 tenderness and affection, so usual in the females of most 

 species. The second died in about a month, and the third 

 lived only to the middle of the following week. The cause 

 of this was that the mother soon completely lost her milk. 

 The female of this species was a little larger than the 

 male, but similar in colours. The tuft of white and stiff hairs 

 surrounding the ear, gives a very peculiar cast to the phy-

 black head. 



The young Ouistiti differed from the adults both in 

 general form and colours. The head was large in propor- 

 tion to the body, and the posterior part of the latter very 

 small. Its entire fur was of an uniform blackish gray. 

 This young animal did not live long enough to afford many 

 opportunities of observation ; near the end of his life, 

 when his father was fatigued in carrying him, and his mo- 

 ther would receive him no more, he would mount to the 

 top of the cage. Having got there, and being unable to 

 descend, he would send forth a cry of distress, which occa- 

 sionally revived the solicitude of his parents, who would then
