border with a small median incisure. The thick symphysial 
part of the mandible does not surpass the point of the snout. 
Operculum a little broader than half its height, its hindmargin 
rounded. Lower border of suboperculum convex. Praeopercu- 
lum large, its posterior angle rounded. The distance between 
the origin of the dorsal and the caudal is one eye diameter 
longer than its distance from the snout. Base of dorsal as 
long as its height; longer than head without snout. The dis- 
tance from the base of first ray of first anal to base of last 
ray of second anal about as long as dorsal. Base of first 
anal as long as head without snout. The distance of the two 
anals equals length of second anal or '/, of eye. Pectorals as 
long as head without snout, situated low down. Origin of 
ventrals below origin of dorsal. Maxillary with small teeth, 
intermaxillary with distinct curved teeth, similar but larger 
ones in a series in the mandible. Small teeth on vomer, pala- 
tines, pterygoids and tongue. Nineteen thick, finely serrulated 
gillrakers, shorter than branchial filaments, somewhat shorter 
than pupil. Scales thin, smooth, their hindmargin rounded 
and entire. Ten flattish scutes with a long keel between 
pectorals and ventrals, 8 postventral sharper and more pro- 
minent scutes. Yellowish, point and top of head and back 
with dark stips. Opercles silvery, fins hyaline, caudal powdered 
with black, its margin blackish. Length nearly 90 mm.
