Cynoglossus nigropinnatus Ochiai, 1959:205 [type-locality: Owase, Mimase, Kochi, Japan]; 1963:85, pl. 19.

DESCRIPTION.—Based on 34 specimens, 89.0–158.0 mm SL.

Depth of body 25.47–35.62 (M = 28.97), length of head 18.52–24.11 (M = 21.25) percent of standard length. Diameter of eye 10.53–21.05 (M = 14.18) percent of length of head, interorbital space absent. Two nostrils on ocular side, anterior nostril tubular in front of fixed eye, posterior nostril simple, just above anterior border of lower eye. Snout rounded, 25.0–37.14 (M = 31.81) percent of length of head, rostral hook short, extending only to front of anterior nostril. Maxillary extending to just below middle of fixed eye; angle of mouth extending to below vertical from anterior half of lower eye, much nearer to tip of snout than to branchial opening; tip of snout to angle of mouth 33.33–52.63 (M = 43.84), angle of mouth to branchial opening 36.36–63.16 (M = 56.02) percent of length of head.

Scales: Ctenoid on both sides, including those on lateral lines; scales small, moderately serrated with short ctenii on blind side, weakly serrated on ocular side.

Lateral-Line System: Two or three lateral lines on ocular side. Dorsolateral line undulated, interrupted at middle of body, becoming obscure or runnng backward along the dorsal contour entering dorsal fin along 8th to 12th rays counted from the rear; the ventrolateral line absent or present, when present either interrupted at middle of body or running backward and entering anal fin a few rays counted from the rear. The dorsolateral line is usually well developed when the ventrolateral line is present to the fullest extent. Midlateral line with 60–67 (M = 63) scales, 11–12 scales between middle and upper lateral lines. No lateral line on blind side.

Interlinear scale rows 11 12

Frequencies 17 14

Fins: Dorsal with 103:110 (M = 107) rays, anal with 84–86 (M = 85) rays, caudal 10 in 5 specimens (radiograph).

Vertebrae: 52, comprising 9 abdominal and 43 caudal elements in 5 specimens (radiograph).

Coloration: Upper side brownish, with or without dark blotches, blind side yellowish in preserved specimens.

Size: Largest specimen examined, 168 (158 + 10) mm, is from Mimase, Kochi, Japan.

DISTRIBUTION.—Japan.
