Snout short, a little over 1/2 eye diameter; maxilla moderate, tip bluntly rounded, failing to reach pre-operculum by 1/3 to 1/2 pupil diameter; gill cover canals of walkeri-type. Anal fin short, its origin a little behind base of last dorsal fin ray. A silver stripe along flank, widening to about 1/2 eye diameter over anal fin base.
