A. Nigra, pilis ad basin fulvis, lateralibus longis. 



Hab. New Grenada. 



Head, limbs, and tail black : hairs of back and sides very long, forming a 

 kind of mantle as in the Colobus guereza, of a yellowish-brown color, tipped 

 with black; hairs of body black at their tips and yellowish-brown throughout 

 the remainder of their length. 



Of this rare species the Smithsonian collection contains four specimens, col- 

 lected by the Atrato Expedition ; the hairs of the mantle appear to be bright 

 yellow in youth, becoming brown in the adult. From the great mutilation of 

 "the specimens I am unable to give other than approximate measurements.
