DESCRIPTION.—Dorsal fin XXIV-XXV,11–13 (24.9, 12.1); total dorsal-fin elements 36–38 (37); anal fin II,20–22 (21.4); pectoral fin 15; pelvic fin I,4; caudal fin 13 (7–9 branched); lateral-line scales 41–45 (43.4); vertebrae 13–14 + 27–29 = 41–43 (usually 14 + 28).

Morphometrics based on sixteen specimens: SL 33.0–114.0 mm; head length 25.6–31.0; head depth 19.1–23.3; head width 16.0–21.4; upper jaw length 12.4–16.0; eye diameter 6.4–9.7; snout length 7.1–8.3; interorbital width 3.0–4.5; predorsal length 19.7–25.3; preanal length 48.3–53.0; caudal-peduncle depth 8.0–9.7; caudal-peduncle length 5.7–8.9; pectoral-fin length 15.4–24.8; pelvic-fin length 13.2–18.7; first dorsal-fin spine length 6.3–9.1; fourth dorsal-fin spine length 7.6–10.9.

Orbital cirri: Multifid, bushlike, 10–20 branches arising from well-developed common stalk, entire cirrus usually less than half orbit in length; nasal cirri: smaller than orbital cirrus, multifid, 5–10 branches, less than one-third orbital length; nape cirri: 3 patches, each oriented transversely, each patch with 1–16 simple, fringelike cirri, each lateral patch slightly posterior to median patch; jaw teeth consisting of enlarged outer row with well-developed patches of minute teeth posteromedially; upper jaw teeth occur posteriorly only slightly more than half distance to rictus; palatines and vomer with continuous patches of small teeth; gill rakers 2 + 6 − 7 on first arch; spinous dorsal fin uniformly low, first dorsal-fin ray twice length last spine, last ray bound to peduncle for half ray length; anal fin not adnate to peduncle; pectoral fin rounded; pelvic fin rounded; pelvic fin with second ray longest, first and third rays approximately equal, fourth ray (innermost) shortest, membrane incised between first and second rays only.

Body elongate, somewhat compressed; greatest body depth 3.5–4.0 in SL; head depth greater than head width; jaws terminate posteriorly near posterior border of orbit; scales smaller on belly and pectoral-fin base than on remainder of body; no scales on head anterior to nape or on fin membranes; well-developed sensory pores on dorsal half of head, sometimes raised.

Color in alcohol: General ground color light to dark brown; body irregularly marked with dark (brown to black) mottling, sometimes appearing as indistinct bars; occasionally 5–6 well-developed, black rectangular blotches along dorsal fin base; blotches sometimes continuing as irregular bands across body, usually not quite reaching anal fin but extending onto fin rarely; blotches usually continuous with mottling on dorsal fin; dorsal and lateral aspect of head dark brown; dark brown spots usually covering cheek and suborbital region; under surface of lower jaw and branchiostegal membrane unmarked, lighter; all fins except pelvics with some spotting, a few discernible bands usually visible on caudal fin; cirri dark brown at base, unpigmented at tips. No obvious sexual dichromatism.

Markings most distinct on specimens less than 80 mm SL. Specimens smaller than 50 mm SL with distinct markings on head: oblique bar originating at midventral edge of orbit and extending posterio-ventrally to posterior edge of preopercle; well-developed blotch on posterior rim of orbit and series of 5–6 marks along opercle, appearing to be remnants of additional indistinct oblique bars; dorsal fin with well-defined ocellus between second and fourth spines, covering most of fin membrane (only faintly visible in larger specimens).
