Hydra and hydromedusa specimens were collected from the Jisanchon Stream in Kyonggi-do (Pyongtaek-shi) and the coasts of Geojedo Island (Jangmok-ri), Korea during the period July 1999-June 2000. They were identified into Hydra magnipapillata Ito, 1947 (Hydridae, Athecatae) and Phialidium folleatum (McCrady, 1857) (Campanulariidae, Leptomedusae) respectively. H. magnipapillata is blackish or light brown color, its cylinder-shaped trunk reaches to 20 ㎜ long and 0.5-0.6 ㎜ wide in fully extended, and has generally 5-6 highly delicate long tentacles. P. folleatum is a small marine hydromedusa, below 5 ㎜ wide and has a minute statocyst between successive tentacles.
