Head large, scaled completely except for a narrow ventrolateral strip on snout; eyes also large; snout short, pointed and with tubercular scales along its leading edge; chin with a small chin barbel. Body tapering to a point posteriorly from behind the insertion of the first dorsal-fin spine. Scales adherent, with 3 to 5 divergent rows of coarse spinules. Pyloric caeca 12 to 14.
