 Alphonse Guichenot. 

 Pomanotis Guichenot, 390; orthotype P. rueescens Guich. A genus not since 

 recognized. The tj'pe P. rueescens was brought by Dussumier from Alipey,* 

 a locality I do not find on the maps, but evidently in India or eastward. The 

 genus is not related to Eucentrarchid.^, as its author suggests, but belongs 

 probably to the Nandid^ (D. XIV, 14. A III, 9) near Pristolepis (Catopra).
