THE HOBNED SAPAJOTJ. 219 



rich colour, it is of a chaste and pleasing tinge, and, 

 when the animal is healthy, of a shining, soft and silky 

 texture. The shades are generally a sort of olive, 

 tinged with a golden yellow on the light parts ; the 

 face is surrounded with a circle of paler colours, which 

 varies considerably in its shade and breadth, being in 

 some nearly wanting. This has given rise to several 

 species being formed from it, and to some confusion 

 in its alliance to one or two other Sapajous; and, 

 indeed, Humboldt seems* almost of opinion, that the 

 animal we have just now figured is only a variety of 

 this. Some have been known to produce young ones 

 in confinement. 



Another allied species, described by the last-men- 

 tioned naturalist, is the Ouavapavi des cataractes 

 Cebus albifrons. It is about the same size, the colour 

 of the face grayish-blue, except the orbits and front,, 

 which are pure white ; and the contrast thus exhibited, 

 at once distinguishes it from those above noticed. The 

 general colour of the body is grayish-olive, lighter on 

 the back and belly. Humboldt met with this animal in 

 troops in the forests near the cataracts of the Oronooko, 

 and the mission of Santa Barbara. They are ex- 

 tremely mild in disposition, and very active ; often 

 kept by the Indians, and one was seen by Humboldt, 

 at Maypures, which every morning caught a pig, and 

 continued seated on his back during the day, while 

 feeding in the savanna round the Indian huts. An- 

 other is mentioned, in the house of a missionary, which
