The height of the body is contained four times and two-fifths in the total length (without caudal), the leng-th of the head three times ; head broader than high, its greatest width being contained once and two-fifths in its length. The diameter of the eye is one-sixth of the length of the head, and two-sevenths of the M'idth of the interorbital space. The occipital process is triangular, shorter than broad, ele- vated along the middle; the basal bone of the dorsal spine smaU, Snout twice as long as the eye. The teeth on the palate are viUiform, and form two separate elongate patches, slightly bent, narrow, and not much shorter than the 6ye, somewhat convergent posteriorly. The maxillaiy barbels extend to the base of the pectoral, the outer ones of the mandible to the giU- opening. Lateral line bifurcate at the base of the caudal fin. The soft dorsal fin as high as the body, ^\dth its spine rather slender, two- thirds as long as the head, and serrated posteriorly. Adipose fin much shorter than the dorsal. Pectoral fins two-thii'ds as long as the head ; their spine is stronger, but little shorter than that of the dorsal fin. Caudal with the lobes pointed, its length being two-elevenths or one- sixth of the total. Fins yellowish. Madura. «. Type of the species. From Dr. P. v. Bleeker's Collection. V:£^ 40.
