Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 0; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 17 - 21. Body rather elongate, but somewhat compressed. Snout fairly long, almost equal to eye diameter; maxilla moderate, tip bluntly pointed, reaching onto inter-operculum, but not to edge of gill cover; panamensis-type gill cover canals. Anal fin origin a little behind midpoint of dorsal fin base. Silver stripe along flank, deeper above anal fin (more than eye diameter).
Occurs in coastal waters. More data needed.
