This was previously recorded by Clark (1982) and by Liao & Clark (in press) as Ophidiaster armatus Koehler, 1910 but both authors now believe that Chinese specimens are specifically distinct. SYSTEMATIC DESCRIPTION Family OPHIDIASTERIDAE Genus Ophidiaster L. Agassiz, 1835 Ophidiaster multispinus sp. nov. Fig. 1, pi. 1 Ophidiaster armatus: Clark, 1982:487, 490; Liao & Clark (in press): .[Non Ophidiaster armatus Koehler, 1910]. HOLOTYPE. IOAS:E1070, Hainan Strait, southern China (20°15'N, 110°15'E), 55 m, rocky, collected July 10, 1960; paratypes IOAS-E-1071, 4 specimens from Xiamen (Amoy), Fujian Province, 1975. Description. R (major radius) 55-70 mm; r (minor radius) 10 mm, br (arm breadth basally) 11 mm. Disc small, arms five, unequal, cylindrical, only tapering slightly in the distal third to rounded tips. Abactinal plates large, more or less triangular in shape, slightly convex, covered with numerous coarse granules, density in the central part of the plates 12-18/mm2. Abactinal plates on dorsal surface of arms arranged in three regular longitudinal series, together with the two marginal series each side forming seven regular longitudinal series as well as transverse ones. Papular areas distinctly arranged in eight longitudinal series but the lowest on each side with only a few pores in each area. No pedicellariae detected. All the marginals, except the basal three to five, armed with a fairly conspicuous short blunt spine, these forming a longitudinal series but missing on occasional
