The body somewhat rhomb-form, but the lower part towards the anal fin, more expanded than the back; com¬ 
pressed, squamous, and rough. 
The head compressed, with scales on the vertex only; the rostrum projecting a little. The mouth, in respect 
to the tail, is middle, but much more distant from the anal than the dorsal fin, it appears very small, when 
shut. The jaws extractile, the upper longest, and rough as a file. The eyes near the rostrum, large, round. 
Nostrils small, round, double. The opercula smooth, the membrane concealed. 
The trunk. The back assurgent, carinate; the breast and belly declivous to the anal fin; the sides very 
compressed. The lateral line arched. The anus distant from the tail. 
Refills. The dorsal and anal are alike in shape, the spines and two first soft rays assurgent, then declining, 
and the last ten rays equal; the pectoral low, short, acuminate above; the ventral fin single, remarkably small, 
consisting of one short spine, and three or four setaceous rays; the caudal slightly concave or lunate. All the 
fins are squamous. 
The colour silvery, with three dusky, oblique streaks on the shoulder; the dorsal fin yellow, with a black 
margin ; the anal white, with a black margin; the caudal is yellow, slightly tipped with black.
