More or less depressed forward, compressed posteriorly ; head broadened ; 

 snout blunt ; caudal fin and pedicel deep. Mouth developed laterally and 

 horizontally ; lower jaws longer, firmly united, upper protractile. Teeth 

 conical, in bands, larger in the outer series. Brancliiostegal rays five to six. 

 Pharyngeal teeth with a hook and a shoulder, some to many, according to 

 the species, enlarging and becoming molars with age. Gill openings wide ; 

 membranes united, free from the isthmus. Dorsal and anal behind the 

 middle of the body, opposed, the former commonly larger and originating a 

 little farther forward than the latter. Anal not modified into an introraittent 

 organ in the male, but generally, as other fins, a trifle larger in that sex. 

 Intestine rarely long. 



This genus is subdivided into four or five subgenera : Fimdulus, with the 

 type F. heterocliius, Hydruryyra, of which the tj'pical species is F. mujalis, 

 Xerdsma, containing F. cidenatus and its closer allies, Plancfcrus, based upon 

 F. Kansce, and possibly a fifth for trans-Atlantic species, of which F. hispanicus 

 is best known.
