Dorsal 10-11, with 8 or 9 branched rays, its origin equidistant from tip of snout and base of caudal; anterior rays longest, nearly as long as the head. Anal 26-30, with 24 to 27 branched rays, produced anteriorly. Pectoral extending beyond the base of ventral; ventrals originating in advance of the dorsal, extending to the anal. Caudal forked. Caudal peduncle as long, or nearly as long as deep.
