Mr. O. Thomas in his valuable paper on Linnzan types (I. c.) 
has followed Gray in placing P. NEM#us in a generic rank distinct 
from all other Langurs. For the present species, Gray chose the 
term LasiopyGa, proposed by Illiger in 1811 for nicTiTaANs and 
NEM#uS species of different genera, restricted to NICTITANS by 
Geoffroy in 1812, who selected NEmMzus for the type of his genus 
PycaTHrix. Gray knew this for he cites Pycaturix, but he did 
not heed the fact that the two species concerned were of different
