Some echinoids were collected at about 20m depth of the sea in Moseulpo of Jejudo Island. Among them two species, Diadema setosum (Leske, 1778) and Toxopneu-stes pileolus(Lamarck, 18716), turned out to be new to the Korean fauna. They were redescribed on the morphological characteristics with illustrations. The order Diadematoida is new to Korea. Fourteen echinoids species so far have been report-ed from the sea around Jejudo Island in Korea.
