摘要
Fifty-seven stations （48 grid stations and nine stratified stations） were sampled across the study region （67.000°-88.394°N, 152.500°-178.643°W） during the 4th Chinese National Arctic Research Expedition （CHI- NARE 4） from July to August 2010 by the icebreaker R/VXuelong. A total of 24 species of Hydromedusae were identified from 130 zooplankton samples, of which seven species belonged to Automedusa, eight species to Anthomedusae, four species to Leptomedudae, and three species to Siphonophora. Catablema multicir- ratum Kishinouye, 1910, Bougainvillia bitentaculata Uchida, 1925, and Euphysajaponica （Maas, 1909） were recorded for the first time in the Arctic sea. In the present paper, 18 species of Hydromedusae were described and illustrated, of which three species were described for the first time in the Arctic sea, and 15 species were described for the first time in China.
