head short, compressed, the profile obtuse; mouth small, ter- 

 minal, the jaws subequal; premaxillaries not protractile; jaws 

 each with a single series of weak teeth; scales very small, 

 cycloid, silvery, loosely inserted, extending on the vertical fins; 

 opercular bones entire; gill membranes separate, free from the 

 isthmus; gill rakers moderate; lateral line continuous, concur- 

 rent with the back; dorsal fin long, more or less elevated in 

 front, preceded by a few indistinct spines — usually one or more 

 procumbent spines in front of dorsal and anal, each of these 

 with a free point both anteriorly and posteriorly; anal fin 

 similar to dorsal, or shorter, usually with three small spines; 

 ventral fins wanting; a single small, sharp spine, attached to the 

 pubic bone, occupying the place of the ventrals; pectorals long 

 and narrow; caudal widely forked. Species few, mostly Ameri-

 prominence of the pelvic bone, which projects as a lamina 

 beyond the skin. (After Jordan and Evermann)
