1. This genus is allied to Siniperca but with deeper body, much larger cycloid scales, na 

 true canines and many fine antrorse teeth on the preopercle. The black flap on the 

 opercle suggests that seen in the American genus Lepomis (Iiryttus), a group of fishes 

 which may be descended from relatives of Siniperca and Bryttosus. 



2. This genus is closely allied to the American genus, Stereolepis, apparently differing 

 in the very high dorsal spines and in the naked top of the head.
