  • Some hyromedusae were collected from Korean waters with Issacc-Kidd Midwater trawl net or by SCUBA diving during the period from May 2001 to Nov. 2005. They were identified into 14 species of 11 families in six orders. Of these, the following six species are new to Korean fauna: Olindias formosa (Goto, 1903) and Proboscidactyla stellata (Forbes, 1846) of the order Limnomedusae; Aglantha digitale ($M\ddot{u}ller$, 1776) and Rhopalonema velatum Gegenbaur, 1854 of the order Trachymedusae; Solmundella bitentaculata (Quoy and Gaimaud, 1833) and Aegina citrea Eschscholtz, 1829 of the order Narcomedusae. The order Narcomedusae and the families Rhopalonematidae and Aeginidae are first recorded in Korean waters. As a result of the present study, the Korean hydromedusae consist of 26 species of 19 families in six orders so far.

  • Some hydromedusae were collected from Gijang (Busan), Yeounggwang, Munseom (Jejudo Is.) and Shinhangman with Issacc-Kidd Midwater trawl net or by SCUBA diving from 2001 to 2003. They were identified into five species of five families in three orders and are new to the Korean fauna. Bougainvillia ramosa (van Benenden, 1844) of the family Bougainvilliidae in the order Anthomedusae, Phialidium hemishaericum (Linne, 1767) of the family Campanulariidae and Aeguorea macrodactyla of the family Aequoreidae in the order Leptomedusae, Diphyes dispar (Chamisso and Eysenhardt, 1821) of the family Diphydae and Abylopsis tetragona (Otto, 1823) of the family Abylidae in the order Siphonophora. With a result of this work, the Korean hydromedusa fauna consists of 31 species of 18 families in six orders.

  • Some siphonophores were collected from the Korea Strait, $33^{\circ}59'N-129^{\circ}17'E$ and Yeosu with Issacs-Kidd Midwater trawl net in Sep. 2002. They were identified into Diphyes chamissonis is Huxley, 1859 and Abylopsis eschscholtzi(Huxley, 1859) in the suborder Calycophorae of the order Siphonophora, respectively. They are new to the Korean fauna. As a result of this work, six siphonophores of four families have been reported in Korea.

  • Two cold-water coral taxa, Octocorallia in the class Anthozoa and Stylasteridae in the class Hydrozoa, were identified. Deep-water samples were collected in fishing nets at depths ranging between 20 and 200 m along the coasts of the East Sea in Korea from 1976 to 1993. The two species found in this study represent new records for Korea: Paragorgia arborea (Linnaeus, 1758) in the class Anthozoa, and Stylaster profundiporus Broch, 1936 in the class Hydrozoa. Two families, Paragorgiidae and Stylasteridae, are also newly recorded in Korea. Furthermore, the species name of another cold-water gorgonian species, Primnoa pacifica (Kinoshita, 1907) in the family Primnoidae, is amended in this report. The two newly recorded cold-water coral species from Korea are described in detail based on their morphological characteristics. Paragorgia arborea is characterized by its growth form, medulla and cortex, zooid dimorphism, canal system, and spicule composition. Stylaster profundiporus is distinguished by its external skeletal characteristics, such as the coordination of dactylopores and gastropores, presence or absence of gastrostyles and dactylostyles, cyclosystem orientation, ampullar position, gastropore tube shape, and coenosteal texture.
