The length of the head is two-sevenths of the total (without caudal); it is broader than high, its greatest width being three- fourths of its length. Head granulated above; the occipital process is triangular, sharply keeled along the middle, longer than broad, with the lateral margins nearly straight. The teeth on the palate are obtusely conical, arranged in four patches : a smaller one on each side of the vomer, and a larger one on each palatine bone. The maxillary barbels extend to the root of the pectoral. Dorsal fin higher than the body; its spine is rather strong, slightly serrated along both edges, and as long as the head without snout; pectoral spine as strong as that of the dorsal fin.
