This study was conducted to compare the genital organs of 14 land snail species belonging to family Bradybaenidae in Korea. The species used for present experiment were characterized by well developed dart sac, accessory sacs and two mucous glands between accessory sacs. No flagellum in the snails of three species employed(Acusta despecta sieboldiana, Koreanohadra kurodana, K. koreana) was observed in this study. The similarity value between Koreanohadra kurodana and Koreanohadra koreana (S=0.834) was more higher than the other species pairs. The higher value followed was recorded between Aegista gottschei and Aegista pyramidata (S=0.761). The clustering type by anatomical genital organs was similar to that analysed by the shell morphologies.
