168 DESCRIPTION OF THE SIMIA SAGULATA.

 man, at the crown, whence it passes down in every 

 direction ; — a circumstance not common in the mon-

 wood-brown and yellowish-brown ; and, on the back 

 and sides, passes into the latter. The back of 

 each hand is of a ferruginous brown, as in the 

 Preacher monkey. The fingers of all the extre
