Head ovoid, deeper than wide in larger specimens than smallest, snout gently sloping in all. Scales cycloid, relatively sparsely distributed in these juveniles, absent on fins and pectoral base and axil; scales present in nape to about one eye diameter posterior to eye in smallest specimen, to interorbital area in others. Eye small, rounded, entering dorsal profile of head in larger of the three fish. Gill slit moderate, reaching ventrally to lower edge of pectoral base or just below it. Opercular lobe at dorsal margin of gill slit slightly rounded posteriorly, extending forward about one eye diameter except on right side of MCZ
