Description
Size: 17-25 cm.

Color: In alcohol specimens golden, brownish above. Pectorals usually black.

Height 2.9-3, 4.1 in length with caudal. Head 3.4-3.5, 4.5-4.9 in length with caudal. Eyes 3.9-4.1, 2.3-2.6 in postorbital part of head, and scarcely less than the interorbital space. Snout much shorter than eye. Mouth large, reaching far behind eye. Maxillaries scaly, 1.6-1.8 in head. Head covered with scales to end of snout. Nostrils close together, about half way between tip of snout and eye. Praeoperculum rather coarsely serrated in small specimens, less so in larger ones, the inferior spine more or less longer and coarser than the others. Angle of praeoperculum somewhat rounded and produced. Upper lip absent, lower lip well developed but not continuous at symphysis. Rather narrow bands of teeth in jaws, on vomer and on palatines. Origin of dorsal between that of ventrals and pectorals. First dorsal spine of first dorsal minute, second one thick, stronger but shorter than third, somewhat shorter or longer than postorbital part of head. Origin of second dorsal slightly in advance of that of anal, its spine comparatively strong, 3/4 or somewhat more of second spine of first dorsal. Third anal spine rather strong, 2/3 of that of second dorsal. Caudal deeply forked, the lobes pointed. Pectorals much longer than head, reaching on anal or not so far. Middle pectoral filaments longest, reaching almost to tip of caudal. Ventrals equal to or longer than postorbital part of head. Distance between origin of ventrals and anal conspicuously less than length of head.
