DESCRIPTION OF THE SIMIA SAGULATA. 169 



est and least powerful of all the phalanges. The 

 nails are much compressed, and sharp-pointed. 



The tail is long, but not prehensile. It is thick- 

 ly covered all round with jet black hairs, and is 

 club-shaped, or thickest toward the extremity. The 

 tip of the tail in the Simia Beelzebub, is reddish- 

 brown, in which it differs from this species. 



This description is equally applicable to five dif- 

 ferent specimens brought to this country in 1817, 

 by my friend Charles Edmonston, Esq. from the 

 interior of the colony of Demerary.
