Size: 37.5 cm.

Color: Bluish brown above, silvery white below, fins yellowish with more or less distinct dusky margins.

Headshields with radiating roughened or granulated lines. The granulated occipital process is triangular, somewhat longer than broad at its base, elevated mesially and less than twice as long as broad in its middle, its sides convex, the narrow hindborder touches the granulated narrow basal bone of the dorsal, which has wing-like extremities. When young the occipital process is strongly carinated and narrow. The median fontanel begins on the snout, ends before the occipital process and is broadest in the middle. Dorsal profile sloping down in a straight line to the somewhat conical, rounded, slightly prominent snout. Eyes with a free orbital margin, 5-6, situated about in the middle of the head, in young less than twice, in full grown specimens more than twice, in full grown specimens more than twice in the snout, nearly 3 times in the interorbital space. The maxillary barbels extends on pectorals in young, in old specimens not quite to base of pectorals, mandibulary ones to hindborder of gillmembranes, mental ones not so far. Height of dorsal more than 2/3 of head, dorsal spine nearly equal to head without snout, its frontborder granular and serrated at the top as also the whole hindborder. Adipose fin small, its base much less than that of soft dorsal, 5 to more than 6 times in its distance from dorsal. Anal concave. Ventrals distant from origin of anal, much shorter than pectorals, the length of which is equal to head without snout, pectoral spine flattened, serrated at both sides, stronger than and as long as the dorsal one. Sharp villiform teeth in the jaws in an arcuate band, those on the palate globular, in 4 separate patches, two small ones widely separate anteriorly, 2 large pearshaped ones posteriorly, their long axis converging behind. About 9 stiff, somewhat flattened gillrakers, much shorter than branchial filaments.
