 the snout projecting be3'ond the inferior mouth; premaxillary very

 of opercle; jaws, vomer, and palatines with small, sharp-pointed teeth 

 arranged in a single row; tongue covered with velvet-like teeth; gill- 

 rakers tine, closel}" set, the longest rather longer than the eye. Dorsal

Coast of China, sometimes extending to Southern Japan; originally 

 described from Nagasaki, but we have seen only Chinese and Korean 

 specimens. On the coast of China is a closely related species, some-
