Size: 40-130 mm

Color: Female head brown above, pale below. No dark markings on head except for traces of two broad, short bands from back of eye. Head covered everywhere by small white spots, except on throat, those on snout and upper lip rather widely spaced and sharply defined, those on side of head densely packed together, those on top of head larger and more widely spaced, few, or none, elongated and run together in vermiculations. Four broad silvery bands across edge of upper lip but not extending up unto snout. Throat rather evenly pale, an incomplete silvery Y antero-mesially; short white dashes at corner of mouth are not extended as chevrons on to throat. Six broad, vertical dark bands, rather obscure, on sides of body, extending from dorsal fins to well below middle of side, single above, all but last deeply forked below. Abdomen pale but body every place else covered with white spots like those on head, but most of those on body horizontally elongated and somewhat run together giving the appearance of a number of narrow, horizontal lines running together in a network enclosing the light dots and spaces. In large specimens the dots become much smaller and more numerous until the horizontal arrangement is lost sight of completely and the board vertical dark bands become even less distinct. Base of pectoral and anterior part of fin similarly white spotted, but with a broad, light vertical band with only a small amount of vermiculations on it. Spinous dorsal mottled with vermiculations and without distinct dark spots or pattern. Soft dorsal also mottled but with numerous fine, oblique, dark lines. Anal with white spots and mottlings more sharply defined and distinct than on dorsals. Caudal crossed by numerous fins, vermiculate, brown lines enclosing light spots. Pectoral crossed by 2 or 3 broad white bands which are more or less vermiculated with narrow, brown lines, especially basally. Ventrals uniformly pale. Male: Like above, but vermiculations not so evident and sharply out standing.

Crest on head barely noticeable as a low ridge, not as high as wide. Nasal cirrus of 4 to 10 simple filaments arranged palmately at end of short pedicle. Supra orbital cirrus nearly as long as eye, pointed, with 4 to 12 simple filaments on either side of cirrus, arranged evenly along cirrus and not bunched at its base. Nuchal cirrus single on either side, slender, pointed, about equal in length to diameter of pupil, either simple or with one short sub-filament, but never with a group of filaments. Fore head evenly rounded. Pupil somewhat oval and slanting downwards. Upper lip strongly crenulate for entire length, but crenulations smaller toward corners of mouth. Canine tooth posteriorly on dentary blunt, snout, about 1/2 pupil in length. Depth 4.9 to 5.3. Head 4.3 to 4.7. Lateral line curving down behind pectoral and continuing towards caudal as an interrupted series of single pores. Last dorsal spine hidden at base of first ray, spinous dorsal lower than soft, membrane between two not deeply notched, last spine 1/2 length of neaxt preceding, membrane from last dorsal ray reaching to, but not over, first small ray of caudal. Last anal ray completely free from caudal peduncle.

Oviparous. Eggs are demersal and adhesive.
