Description
Size: 18-20 cm.

Color: Silvery on abdomen, brownish on back; no dark spots on snout, head or dorsal fin; faint dark bands across the lateral line. Fins yellowish (often blue-green due to settlement of algae which color becomes prominent on preservation in formalin). Sides of body with grey, wavy vertical lines descending from the back, perhaps fading away after death.

Moderately compressed, dorsal profile more convex than ventral, strongly elevated and curved behind occiput. Height 1.8-1.9 [2.2-2.3 with caudal] in length, head 3.4-3.7 [4-4.2]. Eye 3 in head, in young shorter, in old specimens about equal to blunt snout, somewhat shorter than interorbital space, which show a rhombic concavity, longer than broad, between the two smooth supraorbital ridges, each of which commences at the inner supraorbital spine, they converge posteriorly and are continued as outer borders of the crested nuchal spine, which is much longer than diameter of eye and curved according to curvature of back. Two rather strong spines above front border of eye. Commencement of gape of mouth below lower margin of eye, mouth when protracted, directed downwards, maxillary surpassing the vertical through front border of eye, mandible slightly concave. Praeoperculum with obtuse angle, its lower margin finely serrated. Teeth in a series in jaws and are small and numerous. Scales small, conspicuous, also on breast fully and conspicuously developed, on anterior part of body somewhat smaller than those of posterior part. Lateral line commencing with a concavity, than curved somewhat upwards and running, less convex than dorsal profile, to base of caudal, with about 60 sensory tubes. Second dorsal spine shorter than half height of body, the following spines rapidly decreasing in size, the third and fourth strongly serrated anteriorly at their base, second anal spine stronger, but conspicuously shorter than second dorsal, the third anal spine anteriorly strongly serrated at its base. Basal sheath of both fins, with hardly prominent blunt spines. Pectorals slightly longer than head without snout, ventrals nearly one third shorter, reaching anal, with a strong spine and a large scale-like axillary process. Caudal emarginate with rounded lobes. The snout is pointed. Occipital profile is a little concave and it rises to meet the dorsal profile. Nuchal spine elevated in middle. Two small spines present on head in a line with front border of eye. Protracted mouth points downwards. Scales well developed on breast. Dorsal and anal spines strong.
