Body compressed; head length about 3.0 times in standard length; interorbital space narrow and concave on account of the elevated supraorbital ridges. Ridges on top of head spiny; supraorbital ridge finely serrated and spiny in its entire length; a spine in front of eye. Height 6.75, 8.25 in length with caudal. Head 3, 3.66 in length with caudal. Eye 3.9, 1.17 in snout. Interorbital space 4.6 in eye, narrow concave on account of the elevated supraorbital ridges. Maxillary reaching to below front border of eye. Villi form teeth in the jaws, on the vomer in two patches, close together, in elongate bands on palatines. A spine, with a minute one in front of it, above anterior nostril, another spine above posterior nostril. A rather large spine on anterior orbital rim. Supraorbital ridge entirely finely serrated. Superior postorbital ridge with four crowded, rather small spine anteriorly and a single large spine posteriorly. Inferior postorbital ridge with two small spines anteriorly, three spines in its middle and three rather large and more distant spines posteriorly. Suborbital ridge with a spine at the beginning, a pair of small spines before eye, another similar pair below anterior half of eye, a rather large spine below posterior border of eye, followed by a row of small crowded spines and ending in the rather long, pointed preopercular spine. Two smaller spines below it. No interopercular flap. Scales before dorsal small, extending forwards in a point to posterior part of interorbital space. The two anterior scales of the lateral line are spiny, a few behind them have a low keel. First dorsal spine half as long as eye, the fourth spine longest and almost thrice the length of the first one. First dorsal ray simple, the other forked. Anal rays broken in the specimens examined. Fourteen rays of the pectoral forked. Origin of ventrals below origin of first dorsal. Preopercle and opercle with ctenoid scales. Scales ctenoid, except those of belly which are cycloid. No antrorse preopercular spine. Two dorsal fins; first dorsal fin with 9 spines, second dorsal fin with 12 soft rays. Anal fin with 11 or 12 soft rays. Caudal fin truncate.
