Body elongate, dorsal profile moderately arched, ventral profile nearly straight from prepelvic region to anal-fin origin. Maximum body depth at dorsal-fin origin. Head low, pointed; mouth inferior and horizontal (gape width 5.2-5.6 in head length). Maxilla extending beyond vertical through anterior edge of eye. Underside of lower jaw with 5 mental pores, 1 median and 2 posterior pairs. Teeth uniformly small, villiform, set in band on jaws.</paragraph>
<paragraph id="D832FE307ECD3ACB7C7FD40E55AF8A42" pageNumber="3">Snout pointed, longer than diameter of eye; its lower edge with three small rostral pores and five marginal pores; nostrils closely set, anterior circular and posterior crescentshaped. Eye elliptical, horizontal diameter longer than vertical height. Laterosensory canal segments in infraorbitals, preopercle, and lower jaw visible externally. Preopercle margin slightly serrate with 7-9 short spines. Posterior margin of postemporal bone covered with small ctenoid scales, having form of bony flap above dorsal limit of gill slit. Gill rakers short and slender; 5-7+11-12=16-19.</paragraph>
<paragraph id="8CD4FB1E16CB88DAA4A0E5F8184E9DD2" pageNumber="3">Dorsal fins: IX-X + I-28-29 (usually X + I-29), first spine very small (less than 1/5 length of second spine); longest spine falling short of base of second dorsal fin spine when depressed; notch present between first and second dorsal fins. Pectoral fin: I + 18-19, falcate, its tip falling sligtly short of vertical through tip of pelvic fin. Pelvic fin: I + 5, first soft ray prolonged as filament, its tip close to anus in smaller specimens, more distant from that point in larger specimens. Anal fin: II + 7, truncate, first spine reduced, approximately equal in length to first dorsal fin spine; second spine rigid, long, and as long as first soft ray. Principal caudal-fin rays: i+9-8+i; caudal fin rhomboidal, with upper lobe slightly convex and lower lobe concave.</paragraph>
<paragraph id="D7AA7C1242E797DF90045A2FFBBAA497" pageNumber="3">Scales usually ctenoid (cycloid on snout, lachrymal, second infraorbital, and preopercle). Anterior half of lateral line curved dorsally, posterior half running straight to posterior margin of caudal fin; 53-56 pored lateral-line scales from supracleithrum to hypural joint; 9-11 scales rows above lateral line; 9-10 (usually 10) scales rows below lateral line. Bases of second dorsal and anal fins covered by 1 or 2 rows of small ctenoid scales. Caudal fin almost completely covered by scales.</paragraph>

Inside surface of opercle with brownish chomatophores, also visible externally as dark blotch. Trunk with about twelve brown, vertical bars and ellipsoid blotches in the region from the rear of opercle to caudal peduncle; posterior blotches often merged along lateral line. Longitudinal stripe sometimes present under soft dorsal-fin base and extending to dorsal edge of caudal peduncle.
