MICROPTERUS Jordan, 1878. ''Body elongate, not greatly 

 compressed ; spines little developed, those of the anal fin, three

 the continuity of the fin ; caudal emarginate ; operculum emar- 

 ginate behind, ending in two flat points ; mouth very large, the 

 lower jaw longest; palatine teeth well developed; tongue and 

 pterygoids toothless ; gill-rakers long and stout, armed with 

 teeth; supplemental maxillary bone well developed." (JORDAN,
