and shoulders ; the whole of the fur being of a uniform blackish-brown color, 

 generally tending to a more decided black in the male, and being browner in the 

 female. In a male example in the Paris Museum, the back is brown and the wig 

 black, while in a female both the back and the wig are more fulvous. Unusually 

 black individuals were described by Dr. Gray as a distinct species, under the name 

 of Chiropotes ater. 



The black saki, or cuxio, as this species is termed in Brazil, appears to be 

 restricted to the lower parts of the Amazon valley. It was observed by Mr. Bates

at Cameta, on the southern side of the Amazon delta, and is stated to dwell in the 

 most retired parts of the forests, in regions where the ground is not subject to 

 inundations. This naturalist was, however, unable to learn anything as to its 

 habits in a wild state. 



The last representative of these monkeys is the white-nosed saki 

 (P. albinasa), which is likewise an inhabitant of the dense forests of 

 the valley of the Amazon. It is of a deep black color, with a paler 

 tinge on the tips of the hair, except on the nose, which is pure white, and thus 

 renders the animal easily recognizable.
