in front dorsal 18; 22; dorsal origin over fifth branched ray of anal 
fin; about 5 or 6+ 10 gill rakers on first gill arch. Additional counts 
recorded in table 20. 
Body and head compressed, the greatest depth near insertion of 
pelvic fins; profile of back in front of dorsal fin straight; ventral profile 
greatly curved; mouth nearly vertical, lower jaw projecting but not 
quite entering profile; snout shorter than diameter of eye; maxillary 
reaching a little past front of eye; belly in front of pelvics rounded but 
midventral line behind pelvics with a keel, anus a little in advance of 
origin of anal fin; adipose fin present, small, its origin over base of 
about second or third from last rays of anal fin; origin of dorsal fin 
almost equidistant between rear of head and midbase of caudal fin; 
pectoral fins pointed, reaching to end of first quarter or first third of 
the length of the pelvics, the latter reaching to anal origin; first few 
branched rays of anal fin longest sometimes with tiny teeth distally; 
margin of dorsal fin rounded; interorbital space rounded, with a 
shallow groovelike depression, somewhat glandular, each side of 
interorbital space over orbits; a fontanel occurs along middorsal line
