Some of the marks may be diffuse, irregular semicircles or circles. The ventral half of body with fine black dots. Tip of snout dotted black. Dorsals, pectorals and ventrals colourless. Inner side of pectoral base dotted black as also the edge of lower half of gill opening covered by opercular flap. The upper and lowermost caudal rays dusky as also the margins of caudal lobes.

Compressed, oblong, dorsal and ventral profile equally convex, rostro-occipital profile ascending in a straight line with a slight frontal concavity, thence dorsal profile with a slight nuchal elevation. Height 2.46 to 3.0 [3.0-3.6 with caudal], head pointed, 3.4-3.7 [3.9-4.5 with caudal] in length. Eye 2.5-3 in head, equal to inter orbital space and equal to or somewhat shorter than snout. Inter orbital space bordered on each side by a smooth supra orbital ridge, continued as outer border of nuchal spine, which is longer than eye, inter orbital space concave with a median ridge, in large specimens nuchal spine with a median ridge, in large specimens nachal spine with a conspicuous median ridge, a pair of postnasal spines, the outer spine conspicuous, directed hind wards. Snout when protracted strongly directed downwards, longer than half length of head. Commencement of gape of mouth opposite lower third of eye. Praeoperculum with rounded angle, its lower margin straight, minutely denticulate. Teeth minute in a single series in jaws. Scales relatively of medium size, conspicuous, adherent, covering also the breast, lateral line much less convex than dorsal profile, terminating before end of dorsal. Dorsal spines slender, the second to fourth subequal, the second about half height of body, longer than second anal which is shorter than head. Pectorals about equal to head without snout. Ventrals two-third of that length. Caudal deeply incised, the lobes acute.
