脊椎骨: 158 - 162. Body uniformly grayish or brown to nearly black. Dorsal fin origin well behind pectoral fin tips; pectoral fin rounded, not elongate and well-developed. Posterior nostril a hole above the upper lip, covered by a flap that extends to or below the edge of the mouth. Upper lip lacks barbels between anterior and posterior nostrils. Pores small but conspicuous, SO 1 + 4, IO 4 + 2, POM 6 +2. Teeth small and conical, biserial on anterior vomer and jaws (Ref. 40865).
身体均匀浅灰色或褐色到几乎黑色。 背鳍起点在胸鳍顶端正后方; 胸鳍圆形的, 不延长与发展良好的。 后鼻孔在上嘴唇上面的一个洞, 被一个延伸到的鳃盖盖着了或在嘴巴的边缘之下。 上嘴唇缺乏在前面与后面的鼻孔之间的触须。 孔小的但是显着的, 因此 1+4 ， IO 4+2 ， Pom 6 +2. 齿小而锥形, 双列的在前面犁骨与颚.(参考文献 40865)
This species is captured by trawl over sand and muddy bottom between 36-1350 and observed from submersibles to be most abundant between 250-350 m, with only the heads exposed over sandy substrates or resting on the sediment with their bodies in S-shaped curves (Ref. 86730). Mature females collected 48-62.8 cm TL (Ref. 40865).
成熟的雌性收集了 48-62.8 公分TL 。
