218 THE NATURAL HISTOET OF 



Systema, Naturae of Linnaeus, from specimens described 

 by Brisson. 



The general colour of those figured by Frederic 

 Cuvier, is a very deep brownish-black, while the spe- 

 cimens which Buffon and Audibert represent, are 

 rather of a reddish-brown. We have copied the figures 

 from Cuvier, being taken from living specimens, 

 and they may be considered as the most correct 

 plates of the adult state of this animal. The Horned 

 Sapajou is one of the largest in the family ; all the 

 upper parts are very deep purplish or brownish-black, 

 nearly black on the head and upon the shoulders, 

 and the dark purple of the skin, which appears on 

 the naked parts, gives a uniformity of shade to the 

 whole. The grotesque figure of the head is covered 

 by the hair of the front, which stands erect, in a 

 curved or crescent form, and, when viewed in front, 

 has the appearance of two horns ; the tips of these 

 hairs, and those on the cheeks, are of a paler shade. 

 A variety which Cuvier figures has a greater portion of 

 white about the tufts and-jaw. 



Geoffroy and Desmarest give French Guiana as 

 the native country of this species. 



The most common species of Sapajou, and that 

 which is most frequently seen in this country, is the 

 Weeper monkey, Cebus appella of zoologists. It re- 

 commends itself for confinement by its good temper, 

 playful disposition, and hardy constitution. It is also 

 of a small size ; and, though not clothed in a fur of
