Total 938 actinomycete strains were isolated from 59 soil samples collected at Cheju island. All of these isolates were identified to the genus level based on morphological and physiological characteristics. As the result, 62.6% of those isolates were Streptomyces, 16.4% were Micromonospora, 8.6% were Nocardioform group, 2.2% were Actinomadura, 1.7% were Microbispora, 1.6% were Nocardiopsis, 1.0% were Streptosporangium, and 5.9% were the others. As the sources of soil, Streptomyces and Microbispora were abundant in grassland soil, Streptomyces and Micromonospora were abundant in field soil, and Micromonospora were abundant in forest soil. Especially, Nocardioform strains were abundant in natural caves.

A total of sixteen Xylotrechus species from the Korean peninsula are recognized, including a newly recorded species, Xylotrechus pavlovskii Plavilstshikov, 1954. We present brief descriptions of the Korean Xylotrechus species, except four species which could not be examined in this study. The geographic distribution, host plants, illustrations for each species, and a key to the Korean Xylotrechus species are provided.

One species of the Duplachionaspis, D. divergens (Green, 1899) is newly recorded in the Korean fauna of armored scales (Diaspididae). The characters of this genus and species are here redescribed from Korean specimens. A key to species of Duplachionaspis from the East Palaearctic Region, photographs and information on the distribution and hosts of this species, are also provided.

A mysid species, Parastilomysis paradoxa Ii, 1936 belonging to the subfamily Mysinae Hansen, 1910 which comprises approximately 90% of all mysid species, is newly reported from Korean waters. The genus Parastilomysis Ii, 1936 which is also new to Korea, is distinctly different from other genera by having biramous third and fourth pleopods of the male, and telson with an apical cleft. In the present paper, authors provide detailed descriptions and illustrations of P. paradoxa based on the specimens collected from the southern coast of the Korean peninsula, and also discuss on the zoogeographical distribution herein. Parastilomysis paradoxa belongs to Mysidae Haworth, 1825, and is the 50th species in Korea.

The paper reviews data available on euglenophycean algae of the genus Eutreptiella from the Russian waters of East/Japan Sea. Five species (such as E. braarudii, E. eupharyngea, E. gymnastica, E. cf. marina, and E. pascheri) were identified in our study. E. cf. marina and E. pascheri were found for the first time in the fare astern seas of Russia (including East/Japan Sea, Bering and Okhotsk seas). Morphological descriptions of species are based on light and electron microscopical studies and supplied with information on ecology and distribution. Original micrographs of these species obtained by light and electron microscopy are presented. It was established that E. eupharyngea, E. gymnastica, and E. pascheri cause water "blooms" in spring and summer in eutrophic coastal areas of Peter the Great Bay (East/Japan Sea), where their cell concentrations at these periods exceed $1\times10^6\;cells\;l^{-1}$.

Colonial ascidians, Clavelina elegans (Oka, 1927) and Clavelina miniata Watanabe & Tokioka, 1973 are reported for the first time in Korean waters. As a result of this study, three species of the genus Clavelina are now recorded in Korean fauna. Clavelina elegans and C. miniata have been reported only from Japan. We expanded the distribution range of these species to Korea. The specimens of C. elegans and C. miniata were collected from the subtidal zone of Beomseom and Chagwido in Jeju-do by SCUBA diving. Detailed descriptions, illustrations and photographs of these species are provided in this paper.
