Distribution. East China Sea, Korea, Japan, 61– 200 m.

Remarks. This species is distinctive in having large abactinal plates (plate area bigger than popular area), generally uniform in size and subquadrate in form, arranged in rather regular oblique transverse rows ( Hayashi 1940). In our specimens morphology of abactinal plates ( Fig. 11 View FIGURE 11 E), the number of spinelets and a single papula ( Fig. 11 View FIGURE 11 E) in abactinal papular areas correspond well with the original description. The observed differences are the following: the holotype has a single series of ventrolateral plate while our specimens occasionally possess a short series of the secondary ventrolateral plate at the arm base; the holotype has 13 to 17 subadambulacral spines while our specimens sometimes possess 9 to 13 subadambulacral spines. We do not regard the presence or absence of the secondary ventrolateral plate as a reliable diagnostic character.
