中文摘要：

裸鳃类是重要的底栖生物类群．部分裸鳃类栖息在码头、养殖网箱、浮标、船底等人工设施上的污损生物群落中．该种生境的裸鳃类国内鲜有报道．2004年11月至2007年9月期间，作者多次在福建省近海污损生物中采集到两种裸鳃类标本．结合其外部形态和内部齿舌形态，鉴定它们为东方伪二列鳃（Pseudobornella orientalis）及透明脊突海牛（Okenia pellucida）．这两种裸鳃类在我国近海均属首次纪录．

英文摘要：

Nudibranchia is an important benthic group. Some nudibranchs are of marine fouling organisms attaching to manual marine facilities, such as wharfs, fishing gears, buoyages, ships and etc. Though nudibranchs are seldom reported in the fouling niche of coastal waters in China, two nudibranchs are often collected as fouling organisms in Fujian Province from November 2004 to September 2007. According to exterior morphology and interior radula morphology,they are identified as Pseudobornella orientalis Baba, 1932 and Okenia pellucida Burn, 1967 are new records in the coastal waters of China.
