背的軟條 (總數) : 67 - 73; 臀鰭軟條: 47 - 51; 脊椎骨: 37 - 38. Diagnosis: Dorsal rays 67-73; anal rays 47-51; the dorsal, anal, and pelvic rays are unbranched; lateral line scales 76-84, including 14-16 anterior to a vertical at upper end of gill opening; lateral line on ocular side of body projecting well above upper eye, but curving downward on head toward upper eye; vertebrae 37-38 (modally 37); dorsal pterygiophores anterior to fourth neural spine 11-13; body depth 2.35-2.5 in SL; large head, its length (HL) 2.9-3.4 in SL; snout length 3.2-3.65 in HL; small eye, diameter 8.7-11.7 in HL; interorbital space very narrow, least vertical width 9.9-23.8 in HL; maxilla extending to or a little beyond a vertical at rear edge of lower eye; upper end of gill opening on a horizontal passing slightly below lower eye; tubular anterior nostril very short, not approaching edge of lower orbit; slender cirri present on front of snout, along ventral side of head, and edge of operculum on blind side, but none along edge of membranous ridge of dorsal and anal rays; caudal peduncle present but extremely short, its length 21.8-64.0 in HL; caudal-peduncle depth 2.0-2.55 in HL; longest dorsal ray 2.05-2.2 in HL; caudal-fin length 3.8-4.2 in SL; pelvic-fin length 2.5-3.1 in HL, usually reaching to base of second anal ray; color of ocular side in alcohol brown with three rows of dark brown blotches about twice orbit diameter, one row dorsal (but well below dorsal fin), one ventral (but well above anal fin), and one along lateral line; fin rays light brown, the membranes dark brown (Ref. 57561).
鑑別: 背鰭鰭條 67-73; 臀鰭鰭條 47-51; 背部, 肛門的, 與腹鰭鰭條是不分枝的; 側線鱗片 76-84, 包括 14-16 位於鰓裂的在上端的一條垂直線前; 身體的在有眼睛的一邊上的側線突出的離眼睛上方一段距離, 但是彎曲的向下在對於眼睛上方的頭部上; 脊椎骨 37-38;(典型地 37) 背部的支鰭骨位於第四個髓棘 11-13 前; 體高 2.35-2.5 分之一標準體長; 大的頭部, 它的長度 (HL)2.9-3.4 分之一標準體長; 吻的長度 3.2-3.65個 HL比率; 小的眼, 直徑 8.7-11.7個 HL比率; 眼間隔非常狹窄又最少垂直的寬度 9.9-23.8個 HL比率; 延伸至的顎骨或稍微超過眼睛下部的在後緣的一條垂直線; 在水平的通過上的鰓裂的上端些微地在眼睛下部之下; 管狀的前鼻孔非常短的, 不接近低眼窩的邊緣; 細長的觸鬚位於吻部前面之上, 沿著腹的頭側, 與鰓蓋的邊緣在沒有眼睛的一邊上, 但是沒有沿著背鰭與臀鰭鰭條的膜狀脊的邊緣; 尾柄呈現但是非常短, 它的長度 21.8-64.0個 HL比率; 尾柄深度 2.0-2.55 HL比率; 長的背鰭鰭條 2.05-2.2個 HL比率; 尾鰭長度 3.8-4.2 分之一標準體長; 腹鰭長度 2.5-3.1個 HL比率, 通常延伸到第二臀鰭鰭條的基底; 有眼睛的一邊的顏色當保存在酒精中時褐色的有三列的深褐色的斑塊大約兩倍於眼窩直徑, 一列背部的 (但是遠低於背鰭), 一腹面 (但是離臀鰭一段距離), 與一沿著側線; 鰭條淡褐色, 薄膜深褐色的.(參考文獻 57561)
