 Small specimens have upper teeth less acute, and no serratures on the lower teeth. 

 Second dorsal less than half the size of the first, commencing about one-third of 

 the length of its base in front of front edge of anal ; anterior edge of anal nearer to 

 the anterior edge of caudal lobe than to posterior edge of base of ventral ; pectorals 

 broad, nearly rectangular at base, narrow towards tip ; anterior edge of base 

 vertically under posterior edge of penultimate gill-opening. Scales very minute, 

 20 in 3 lines about middle of body. Fold at angle of mouth continued above to 

 under middle of eye ; a fold on upper eyelid. Color : Back and upper half of side
