背的软条 (总数) : 75 - 102; 臀鳍软条: 55 - 63. The available specimens of M. smithi differ from all other specimens of a similar total length (6.8-7.2) within the genus by the long skull 7.0-7.6% TL and long lower jaw 11.8-12.5% TL. Furthermore, it is distinguished by the following combination of characters: head long with elongate, pointed snout slightly upturned, rostral fang strongly hooked with distal part in a nearly right angle to dorsal profile of skull, preanal 36.0-37.5% TL, and at least 7 teeth in jaw (Ref. 34506).
M. smithi 的有用标本相似本属里面的全长 (6.8-7.2) 藉由长的头盖骨 7.0-7.6% TL 与长的下颌 11.8-12.5% TL 不同于所有其他标本。 此外，它被藉着下列的组合特徵区别: 头部长的有细长的, 尖的吻些微朝上又嘴的尖牙强烈地以末梢部的部份钩住在一几乎对头盖骨的背面轮廓,是肛门前的 36.0-37.5% TL 的直角, 而在颌中最少的 7个齿.(参考文献 34506)
The holotypes and paratypes of M. smithi were caught in the water column in a closing net at 4200 and 5200 m, with a sounding at 5800 m (Ref. 34506).
holotypes 与 M. smithi 的副方式于在 4200 与 5200 公尺的一张结束网中的水团捕获, 具有一个测量到的水深为 5800 公尺.(参考文献 34506)
