A few bony plates behind gill opening, not much larger than the scales of the body. Cheeks totally scaled. Chin naked. Lips rather thick. Median teeth in the jaws pointed, longer than the next ones on sides. Origin of first dorsal above upper end of gill opening. First dorsal spine compressed, its anterior side covered with tubercles and spinules, its length equal to the base of the first dorsal. Second dorsal spine half as long as first spine, or somewhat longer, third spine about half as long as second spine. Second dorsal somewhat rounded, the longest ray slightly shorter than fist dorsal spine. Anal similar to second dorsal, but slightly less deep and its base shorter, its origin below 5th dorsal ray. Upper pectoral rays longest, as long as longest dorsal rays, lower most ray half as long as longest pectoral ray. Ventral spine movable, short, covered with tubercles and short blunt spinules.
