Ophiura pteracantha sp. nov.(Fig.1; Pl.Ⅰ:1—3) Description Diameter of disk 6—8mm., length of arms 4—5 times the diameter of the disk. Disk flat, rounded, covered with unequal and slightly imbricated scales, among which the central dorsal, radial and interradil plates are distinct, and forming a pretty rosette. In the median radial line there is a row of two scales separating the two radial shields of each pair. In the interradii there are two rows of scales between the radial shield, and a transverse series of five rectangular scales, connected
