  • Eight caprellids are collected from the several islands off Yeonggwang, Jeollanam-do at June 2007. Among them Caprella chelimana Mayer, 1903 is newly added to the Korean caprellid fauna. We described this species with illustrations and mentioned some differences from Mayer's original descriptions. Caprella subtilis is also the first record since Mayer reported this species from East Sea (Sea of Japan) in 1903.

  • Two new marine sponges in genus Suberites, S. hataedoensis n. sp and S. waedoensis n. sp have been collected from Hataedo Island and Waedo Island, Korea during 2005-2006. S. hataedoensis n. sp. is similar to S. durissimus in the spicule composition and texture. However, they differ in growth form, skeleton and surface. S. waedoensis n. sp. is similar to S. japonicus in spicule composition and skeleton. However, they differ in growth form, surface and texture.

  • As a result of continuous taxonomic study on crabs, Clistocoeloma villosum (A. Milne-Edwards, 1869) is newly reported from Korean waters. C. villosum has no epibranchial tooth on the carapace, while C. merguiense De Man, 1888, only recorded species of this genus in Korean fauna, has two epibranchial teeth. The description and illustrations of C. villosum are provided herein. Korean Sesarmid crabs now consist of 10 species belonging to six genera.

  • A taxonomic study on the genus Nitakra (Ameiridae) is accomplished. A total of five species are collected from coastal marshes, lagoons, and estuaries in South Korea. Among them, the latter three species are newly recorded from Korea: N. spinipes Boeck, N. affinis califarnica Lang and N. pietschmanni (Chappuis). Taxonomic accounts and a key to the species from Korea are given.

  • A taxonomic study on the marine sponges was conducted with materials collected from intertidal zone of Sourthern California (USA) during 2005-2006. They were identified into 13 species belonging to 12 genera, nine families, and seven orders in one class. Among them, common species in Korea and California coastal areas are; Cliona celata, Lissodendoryx firma, Halichondria panicea, Hymeniacidon sinapium.

  • A taxonomic study was carried out on the cumacean specimens collected from shallow coast of the Yellow Sea in Korea. As a result, Bodotria ovalis Gamo, 1965 is redescribed as new to Korean cumacean fauna based on the differences between ours and previous researchers' views on this species. B. ovalis rarely occurs in the coast of the Yellow Sea.

  • Two species of Pareurystheus belonging to the family Corophiidae are added to the Korean fauna: Pareurystheus latipes Tzvetkova, 1977 and P. anamae (Gurjanova, 1952). P. latipes is similar to the P. anamae in the most of morphological characteristics. However, two species differ in the forms of antenna 1, gnathopod 2, pereopods 5-7 and telson. This genus Pareurystheus is reported for the first time from Korea. They are described and figured in detail.
