Holotype. x i. enlarged, becoming canine-like anteriorly; those of inner row of lower jaw moderately enlarged. Margin of praeoperculum with some minute denticulations along posterior edge; angle rounded, with some larger and more distinct teeth; operculum with two weak, flat spines. 9 or 10 gill-rakers of moderate length on lower part of anterior arch. Scales finely ciliated; 47 to 49 in lateral line, 5 or 6 from origin of dorsal to lateral line; lateral line tubules with 3 to 5 short branches. Dorsal IX, I 29-30; spines slender, fourth longest, about f length of head; soft dorsal scaled only at base. Anal II 7; first spine very short; second stronger than those of dorsal fin, length more than \ that of head. Pectoral about | length of head. Pelvics shorter, f length of head. Caudal pointed, middle rays f to | as long as head. Silvery; back darker; dusky patches on opercular region; a dark spot superiorly in axil of pectoral; dorsal fins with blackish margins; pectorals, anal and caudal more or less dusky. Apparently most nearly related to S. aquila (Lacepede), differing mainly in the some- what larger scales, larger eye, pointed caudal fin, etc. Umbrina ronchus,Valenc.
