Two cumaceans species, Eocuma amakusense $Gam{\hat{o}}$, 1967 and E. latum Calman, 1907, belonging to the family Bodotriidae are collected from the southern sea in Korea, and are redescribed. At the present, just one species belonging to the genus Eocuma, E. cf. hilgendorfi Marcusen, 1894 has been reported in Korea. Herein we add two Eocuma species to the Korean cumacean fauna and described them with full illustration contained new information of mouthparts. A key to the Korean Eocuma species is also provided.

Only four species of leuconids have been recorded in Korea, all belonging to the genera Eudorella Norman, 1867 and Nippoleucon Watling, 1991. In this study, Pseudoleucon japonicus Gamô, 1964 belonging to family Leuconidae Sars, 1878 is newly recorded for Korean cumacean fauna. Also, for the first time, the male of the species is fully described and illustrated. The specimens were collected from the exclusive economic zone (EEZ) in the western sea (Yellow Sea) of Korea, with a rectangular dredge during 2007-2008. This species is characterized by the following features: the carapace has strong serrations on the antero-lateral margin and a pair of short oblique ridges on the side surface; the ridges begin near the end of frontal lobe and merge with the dorsal median carina; the appendages, such as antenna 1, pereopod 2 and uropod have a lot of simple setae decorated with a bundle of hairs at the end. The present study represents the first record on the genus Pseudoleucon Zimmer, 1903 from Korea.

The spatial distribution and composition of the mesozooplankton community in the southeastern Barents Sea were observed at 17 stations, from 12 to 28 July 2002. Six taxa of zooplankton were found, including tintinnids, copepods, cumaceans, appendicularians, polychaetes, and barnacle larvae. Copepods were dominant, comprising 74% of the community. The copepod species Limnocalanus grimaldii, Pseudocalanus acuspes, Calanus glacialis, Calanus finmarchicus, and Microsetella norvegica, and the cumacean species Diastylis rathkei and Campylaspis rubicunda were identified. The overall mean abundance of the zooplankton was 72 indiv.l0 $\mu \textrm m^{-3}$ in the study area, ranging from 4 to 197 indiv.l0$\mu \textrm m^{-3}$. Zooplankton was more abundant at the oceanic than the coastal stations. The highest biomass measured was 97.4mg $\mu \textrm m^{-3}$, the mean biomass was 36.9 mg 10$\mu \textrm m^{-3}$, 93% of which was copepods. Pseudocalanus acuspes, C. glacialis, and C. finmarchicus predominated, accounting for 61% of abundance and 86% of biomass. Spatial distributions of the zooplankton community in the study area depended on the variations in water temperature and salinity, which were influenced by freshwater runoff from the continent.

오스트레일리아의 Queensland에 위치한 Cockle Bay의 해초지에서 채집된 Sillago maculata의 식성을 조사하였다. S. maculata (0.5~9.5 cm SL)의 주요 먹이생물은 단각류에 속하는 옆새우류, 게류 및 요각류였으며, 그 외 갯지렁이류, 새우류, 어류, 등각류, 쿠마류 등이 소량씩 위내용물 중에서 발견되었다. S. maculata은 성장함에 따라 먹이생물의 조성이 점차 변하였다. 체장이 작은 개체는 요각류, 게의 유생, 옆새우류를 주로 먹었으나, 체장이 증가하면서 요각류 및 게 유생의 비율은 점차 낮아진 반면, 갯지렁이류 및 어류가 차지하는 비율은 증가하였다. 한편 옆새우류는 조사된 모든 크기에서 가장 선호하는 먹이생물이었다.
