| 摘要: |
| 本文系根据中国科学院海洋研究所历年来在我国沿海潮间带采集的大量标本加以鉴定研究写成。共报告肠鳃类 Enteropneusta 6种，即黄岛长吻虫 Saccoglossua hwangtauensis (Tchang et Koo),短殖舌行虫 Glossobalanus mortenseni Horst，多鳃孔舌形虫 Glossobalanus polybranchioporus Tchang et Liang，肉质柱头虫Balanoglossus carnosus (Willey)，三崎柱头虫Balanoglossus misakiensis Kuwano 和黄殖翼柱头虫Ptychodera flava Eschscholtz。分隶于两科四属。
短殖舌形虫，肉质柱头虫和黄殖翼柱头虫在我国是首次记录，我们均根据其外部形态和内部解剖作了详细描述，并讨论了与前人描述相异之处。到目前为止，多鳃孔舌形除了在我国沿海分布之外，国外尚未见有报道；张玺等在1965年对此种已有详细描述，本文仅对其特征作了记述。黄岛长吻虫是张玺等在国内发表过的，本文进一步对它作了补充描述和修正。三崎柱头虫，过去张玺等没有对它的内部解剖进行过描述，本文根据在我国沿海采到的标本，对它的内部形态特征进行了补充，并与前人描述的某些特征进行了比较和讨论。 |

| Abstract: |
| The present paper presents the results of a study of the Enteropneusta of the intertidal zones of our seas collected by the Institute of Oceanology, Academia Sinica. Six species belonging to four genera and two fami1ies are identified. Saccoglossus hwangtauensis (Tchang et Koo) , Glossobalanus polybranchioporus Tchang et Liang, and Balanoglossus misakiensis Kuwano, have been previously reported while Glossobalanus mortenseni Horst, Balanoglossus carnosus (Willey) , and Ptychodera flava Eschscholtz, are first records for our seas; their external features and internal anatomy are described in detail and some features differing from those described in earlier reports are discussed. A key for the identification of the Chinese Enteropneusta is also given. |
