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 ! / 3 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.

 convex than dorsal, scales firm, thin, ventral scutes prominent. 

 Origin of ventrals before or below origin of dorsal. One anal 

 fin. Teeth on jaws, palatines, pterygoids and vomer.
