la. Posterior upper corner of mandible inside of mouth not turned upward or 

 elevated, toothed edge straight or nearly so; inner upper edge of pre- 

 maxillary each side of middle premaxillary process without a second 

 lateral posteriorly directed process; premaxillary process a little shorter 

 than pupil ; distance from insertion of pelvics to anus about equal to 

 eye and 2^2 times in pelvic insertion to origin of anal fin; thus anus is 

 closer to pelvic insertion than to anal origin; anal rays I, 14 or 15; 

 dorsal rays V to VII-I, 9 or 10; gill rakers about 5+1+21; scales 

 214+43 or 44+3; pectoral 16; outer dorsal half of pectoral vrith a 

 black area, the posterior margin of the fin hyaline; tips of upper and 

 lower caudal lobes blackish ; tip of chin and side of mandible blackish, the 

 free lips at sides of mandible white; outer edges of premaxillary and 

 maxillary blackish anteriorly ; snout blackish ; upper edge of eye black ; 

 a white band around front of eye; snout 1% in eye; eye 2^f, in head; 

 snout 2% and eye IV2 times in distance between origin of dorsals. 



Hepsetia pinguis (Lacepede) 

 1&. Posterior upper angle of mandible inside of mouth elevated or turned 

 upward, toothed edge not straight; inner upper edge of premaxillary 

 at each side of middle process with a groove, then a lateral spinelike 

 process; middle premaxillary processes long and slender, about two 

 or three times longer than pupil ; peritoneum black. 

 2a. Distance from' insertion of pelvics to anus about equal to or trifle longer 

 than eye and 2.8 to 3 times in pelvic insertion to origin of anal fin; thus 

 anus is much' closer to pelvic insertion than to anal origin ; anal 

 rays I, 10; dorsal IV-I, 9 or 10; gill rakers 5 or 6+1+22 or 23; scales 

 2%+42 or 43+3; pectoral 16; pectoral fin rays without blackish 

 area ; caudal fin lobes without blackish tips on specimens up to 55 

 mm. in standard length, base of rays each side of midaxis with a 

 siivery-black spot, somewhat diffuse ; tip of chin and sitles of man- 

 dible blackish, the lips at sides posteriorly white; tip and front of 

 premaxillary blackish; a black patch near front of maxillary; dorsal
