背棘 (总数) : 11; 背的软条 (总数) : 15; 臀棘: 4; 臀鳍软条: 10; 脊椎骨: 27. The slender, slightly compressed body is probably mainly, if not entirely, red in life; 5 rows of oblique scales on cheek; body slender, the depth 3.1 in SL; head length (HL) 2.55 in SL; very large eye, 2.6 in HL; very narrow suborbital shelf; anterior end of the nasal bone is rounded; moderately large nasal fossa spineless; surface or medial edge of the nasal bone spineless; third dorsal spine longest, 2.2 in HL; spinous and soft portions of dorsal fin completely separated; third anal spine 1.35 in HL; pointed caudal fin lobes (Ref. 27370).
主要地被可能是的细长又些微扁长形的身体, 如果不完全地, 活着时的红色; 在颊上的 5个列的斜角鳞片; 身体细长的, 深度 3.1 分之一标准体长; 头长 (HL)2.55 分之一标准体长; 非常大的眼,2.6个 HL比率; 非常狭窄的眶下架; 鼻骨的前端是圆形的; 普通大的鼻窝无棘的; 鼻骨的表面或中间边缘无棘的; 第三个背棘长的,2.2个 HL比率; 刺状的与背鳍的柔软部位完全地分开; 第三个臀鳍硬棘 1.35个 HL比率; 尖的尾鳍叶.(参考文献 27370)
The species may penetrate deeper water (suggested by the large eyes); the 49 m depth could be near the upper limit of its depth range (Ref. 27370).
此鱼种可能深入较深的水域;(建议藉由大的眼) 49 公尺深可能是在它的深度范围的最上层的附近。 (参考文献 27370)
