In this List the members of Pygathrix are included in two 

 genera L.\siopyga, and Semnopithecus. The first is made to 

 contain nem^us Linn., which is an error, for nem^us is the 

 type of Pygathrix, and the type of Lasiopyga is Simia nicti- 

 TANS Linn. The species placed in Semnopithecus are (S.) 

 leucoprymnus = Pygathrix cephaloloptera ; {S.) obscurus 

 Reid; {S.) johni; {S.) entellus; {S.) albipes = Pygathrix 

 entellus; {S.) maurus — Pygathrix aurata; (5.) cris- 

 tatus; {S.) femoralis; (5".) frontatus; {S.) mitratus = 

 Pygathrix aygula; (S.) siamensis; (S.) melanolophus; 

 (S.) nobilis; and {S.) rubicundus.
