In this paper the Author creates the genus PyGaTHRIx with 
Simia nemeus Linn., as the only species and type, and in the 
genus Cercopithecus (Lastopyca), the following members of 
PyGATHRIX are placed: (C.) maurus (nec Schreb.), ex Java = 
(C.) auratus Geoff., first described ; (C.) latibarbatus Geoff., = 
P. CEPHALOLOPTERA (Zimm.), and (C.) ENTELLUS Dufrésn. 
The species of PyGATHRIX in this paper were considered co- 
generic with those of Cercopithecus (nec Gronov.), = (Last- 
opyGcaA), and their characters were overlooked.
