Size: 19-22 cm.

Color: In preserved specimens brown. A black spot at hind border of each scale of lateral line may be present. Dorsal, posterior part of anal, and basal half of caudal with many small black edged ocelli, arranged in longitudinal rows on dorsal and anal, in transverse rows on caudal. Head, body, and tail are covered with similar ocelli, but not distinct in the specimens examined (Beaufort and Chapman, 1951). Pectorals and ventrals yellowish, last named dusky brown at tip.

Height 13.4-13.7, 16.6-17.3 in length with caudal. Head 4.6-5.2, 6-6.3 in length with caudal. Eye 6.1-7.2, 1.7-2 in snout. Inter orbital space narrow, one fourth or three eighths of eye. Lower jaw the longer, with a fleshy symphysial knob. Teeth pointed, those of the lower jaw hooked. Head naked, excepting two rows of small scales, starting from corner of mouth, one running obliquely upwards and backwards to behind eye, the other obliquely down and backwards. The membranes between the rays of dorsal and anal deeply incised, the rays somewhat filamentous, especially the anterior ones of the dorsal. In males the first and second detached rays of dorsal are very long and reach on posterior half of dorsal when laid down. Pectorals pointed, as long as post orbital part of head. Ventrals pointed, half length of snout less than head. Males recognized by long dorsal fin rays and large size. Under dorsal fin with 1 or 2 free pterygiophores. Dorsal soft rays (total): 39-41.
