पृष्ठीय रीढ़ (सम्पूर्ण) : 2; गुदा कांटा: 0. Snout short, blunt, with a broad spinous scute at its tip, its leading edge and most of its underside naked; suborbital shelf very narrow anteriorly; interopercle broadly rounded posteriorly; chin with very short barbel. Scales rather deciduous; body scales with 3 to 10 low, subparallel rows of spinules; gill and gular membranes and interopercle naked. Pyloric caeca short, 5 to 7.
