다국어 초록 (Multilingual Abstract)

Some hydromedusae were collected from the East Sea (3630′124 ′′N and 130 06′446 ′′E), Yousu and Youngkwang with horizontal plankton net during from Nov.2001 to Dec. 2002. They were identified into Proboscidactyla flavicirratain theorder Limnomedusae, and Muggiaea bargmannae and Diphyes bojani in thesuborder Calycophorae of the order Siphonophora, respectively. P. flavicirrataissimilar with P. stellatain the shape and size, but it is distinguished from later speciesin that P. stellatahas six radial canals, 24 short marginal tentacles and dichotomousbranching pattern. The suborder Calycophorae is the first recorded in Korea andposseses only develop a nectosome. In Muggiaea bargmannae , anterior nectophoreis simillar with Dimophyes arctica in the shape of nectophore, but it is distinguishedfrom the later in that D. arcticahas a undivided mouth plate and deeper hydroecium.In Diphyes bojani , anterior nectophore is simillar with Diphyes dispar in the shape ofnectophore, but it is distinguished from the later in which D. dispar has a deeperhydroecium and more prominant dorsal tooth. No posterior nectophores of Muggiaeabargmannae and Diphyes bojani have been observed.
