浙江近海裸鳃类的研究

关于浙江近海的裸鳃类,过去仅有张玺、齐钟彦(1961)、林光宇(1965,1975,1981,1985)洪君超、尤仲杰(1965,1983)等先后零星报道12种,但尚未进行较系统的分类研究。我们整理了中国科学院海洋硏究所历年来在浙江近海进行调查所采集的标本和浙江水产学院1961-1985年在浙江沿海潮间带采集的标本,共鉴定出90种后鰓类。本文报道其中的裸鳃类共32种,分别隶属于14科,17属,其中有1新种,6种在我国为首次记录。在这些种中,1种是环赤道分布种:海神鳃 Gulaucus (Gulaucus) marinus ；2种分布于大西洋、地中海；太平洋:雪白心海牛 Noumea nivalis,围鳃海牛 Joriana tomentosa;有9种是印度-西太平洋的热带种:双色裸海牛 Gymnodoris bicolor,多枝鬈发海牛Caloplocamus ramosus,草莓叉棘海牛 Rostanga arbutus，网纹舌尾海牛 Glossodoris tinctoria,黑枝鳃海牛 Dendrodoris nigra，溅斑舌尾海牛 Glossodoris aspersa,芽枝鳃海牛Dendrodoris denisoni,红枝鳃海牛 Dendrodoris rubra,白斑马蹄鳃 Sakuraeolis enosimensis；其余是西、南太平洋的热带、亚热带种和少数温带种。浙江沿海和日本南部沿海的共有种有20种之多,可见两地区系之相似。这些种能向北越过长江分布至黄海、渤海的有9种,向南分布到南海的有13种,其区系性质应为热带、亚热带。

STUDIES ON NUDIBRANCHIA FROM THE ZHEJIANG COAST

The present paper deals with 32 species of Nudibranchia belonging to the 17 genera, 14 Familiea.The material for study was based on the collections made by the Institute of Oceanology,Academia Sinica in the past years and the Zhejiang Fisheries College during the period 1961-1985 from the littoral and sublittoral zone along the Zhejiang coast. Of these, I species is new to science and 6 species are recorded for the first time from the coasts of China.The Nudibranchia fauna of the Zhejiang coast may be grouped as follows.
