4. Jaws with hooked irregular teeth, and crowded ones be- 

 hind ; branchial membrane with seven rays. 



This group is composed of those genera with wider mouth and jaws, armed with 

 hooked irregular teeth, having others behind them very small and crowded. The bent 

 teeth in the upper jaw are generally longest. The branchial membrane has seven 

 rays. The characters derived from the operculi, as armed with spines or dentated, 

 has afforded to M. Cuvier indications for the subdivision of this numerous group.
