Head broader than higli, its greatest vndth being equal to its length without snout; snout short and obtuse, its extent being one-half of the width of the interorbital space. Teeth on the palate in two widely separate subtriangular patches of moderate size, the vomerine teeth being more or less confluent with those of the palatines. The maxillary barbel extends to the middle of the pectoral fin, the outer of the manchblc being somewhat shorter. The upper surface of the head slightly granidated. Occipital process of moderate length, not much broader at the base than at its concave end, elevated along the middle. The basal bone of the dorsal spine is small, crescent-shaped. Dorsal spine very strong, particularly in its basal half, which is granulated, tapering from the middle ; it is as long as the head. Adipose fin much shorter than dorsal. Pectoral spine shorter and less strong than that of the dorsal fin. Adipose fin black, with its posterior margin yellowish. East Indies. a. Eleven inches long. Piu'chascd of Mr. Frank. b-c.
