石川粗鳍鱼由 D.S.Jordan和 J.O.Snyder(190 1)首次根据一尾采自东京湾口外的标本建立的 ,而本文的标本则采自中国黄海和东海等处。本种在体形、鳞片和身体结节等方面与皇带鱼(Regalecusglecus)相似 ,故常被混淆。经详细研究后 ,作者补充描述了本种的若干重要性状并同体形近似的皇带鱼对比 ,找出两种鱼在背鳍起点和肛门位置、腹鳍鳍条、头部骨片、口部结构、牙齿的有无及其分布、鳃耙数目、眼睛大小、侧线鳞及身体结节特点等方面的显著差别。 For the first time, D.S. Jordan and J.O. Snyder (190 1) were established based on a specimen taken from the mouth of Tokyo Bay, while specimens of this article were collected from the Yellow Sea and East China Sea. This species is often confused with Regalecus glecus in body shape, scales and body nodules. After a detailed study, the authors added some of the important traits of this species and compared them with the similar figures of imperial seafowls, to find out the difference between the starting and anal position of the dorsal fin, the fin of the dorsal fin, the head bone fragment, the mouth structure, the teeth With or without its distribution, the number of gill rakers, eye size, lateral scales and the characteristics of the body nodules and other significant differences.
