Color: In preserved specimens light reddish brown, lighter below. Some scales of black each with a dark brown patch at base, arranged in about 5 groups, separated by vertical light stripes, which are confluent with a light broad band running from head to upper part of caudal. A similar light band lower down on side, parallel to the first and connected with it by about four broad vertical bands, the scales in the inter spaces with dark stripes, forming groups. Similar spots below this band. Upper part and sides of head covered with dark brown spots and stripes, united into more or less conspicuous lines anteriorly, two of which parallel, running from middle of snout to below eye and from there in a downwards curve to lower part of operculum. Dorsal and anal yellowish, sometimes with traces of longitudinal band. A black blotch on second spine and on the membranes before and behind it. Other fins also white or yellowish, the pectorals often dusky at tip. In life the light bands and stripes are dark red and the dorsal and anal have a longitudinal red band.

Mouth slightly oblique, not reaching to below anterior nostril. Lips thick, plated, the inner plate festooned. Teeth moderate, in a single series, the two anterior ones in the upper and in the lower jaw moderate canines. Head naked, with exception of about 3 scales on upper part of opercle. Six or seven scales before dorsal. Dorsal spines short, the first as long as eye, the last as long as snout, the soft dorsal higher than the spinous part, somewhat rounded. Origin of anal below last spine of dorsal. First anal spine very small or absent, last spine longest, as long as longest dorsal spine.
