Distribution. Bohai Sea, Yellow Sea, Japan Sea, Korea Strait, and Aleutian Island to southern California, 0– 400 m.

Remarks. This species is distinguished by the numerous short, almost granuliform spinelets, the three regular series of marginal and ventrolateral plates and intermarginal areas ( Fig. 7 View FIGURE 7 G) confined to small triangular spaces at arm base. Spinelet tips ( Fig. 12 View FIGURE 12 A) are pointed rather than blunt, as indicated in Hayashi’s (1940) description of the species. In our specimens the morphology of most spinelets corresponds well with his description. We observed the character of spinelets in two large dry specimens that are the last ones in material examined is peculiar. Spinelet tips ( Fig. 12 View FIGURE 12 B) were globular and hyaline and under magnification, they appeared pearly and bead like. Fisher (1911c) noticed the quite distinct variation and mentioned that this variation in spinelet morphology may be due to either greater age of the organism or the action of waves. We further examined these two specimens and found that on the ventral surface the tips of spinelets were sharper and less globular. In other words, the tips of spinelets have a tendency to be globular from ventral surface to dorsal surface. They agree with Fisher’s descriptions.
