Dorsal VI, 1-7 ; anal I, 6 ; there are 26 scales in a longitudinal

The body greatly compressed laterally, the back strongly 

 arched, the belly forming a long convex arch, deeply arched in 

 spawning females, the depth 3.2 to 3.46 times in length; the 

 head boldly convex with very full nape, 3.25 to 3.3 times in

 4.5 to 5.2 times in head; the large eyes placed obliquely and 

 very high up, their upper margin forming a hump in the dorsal 

 profile, 3.2 to 3.9 times in head ; no interorbital space, the margin 

 of the eyes touching ; the jaws equal, the mouth terminal, oblique, 

 the posterior angle of maxillary reaching a vertical from middle 

 of eye or, in males, extending beyond pupil but not beyond eye ; 

 the teeth in three rows in each jaw, the outer ones scarcely 

 enlarged ; the opercles covered by four large scales ; the dorsals 

 far apart, the first spine of first dorsal elongate, or the first 

 three spines may be of nearly the same length, all very slender, 

 reaching to or slightly beyond origin of second dorsal, 0.75 or 

 0.8 of head; the second dorsal much lower, of nearly uniform 

 height, the posterior rays falling far short of caudal when

 forming longitudinal rows between blackish lengthwise lines;
