Abstract: The Recent freshwater ichthyofauna from the Japanese islands is, in many respects, different from that of eastern China. The Pliocene and Miocene ones from both areas, however, resemble each other in a greater extent in composition than the Recent ones. The Early Tertiary, i.e. Eocene fish fauna along the coast of the Bohai Gulf, east China shows striking similarity in composition to those of the same age along the west coast of North America demonstrating a "transpacific" distributional pattern. According to their composition and distribution the late Mesozoic, i. e. the Early Cretaceous freshwater ichthyofauna from China, can be subdivided into two distinct assemblages. The one from North China is endemic, while the one from southeastern China exhibits some affinities with the Early Cretaceous ichthyofaunas from northeastern South America and West Africa displaying a distributional pattern involving both northern and southern continents. Discussions on and tentative interpretations about the distributional patterns mentioned above are given in the text.

摘要： 日本列岛和中国大陆东部的现生淡水鱼类区系存在显著的差异，但这两地上新世和中新世的鱼类区系已发现的组成成分却似乎比现代鱼类区系要接近得多。而在中国东部渤海沿岸发现的早第三纪或始新世的鱼类区系成分则显示出与北美西岸同时代鱼类区系的惊人相似，展现出一个“跨太平洋格局”。中国中生代晚期或早白垩世的鱼类区系从组成和分布上可以划分为两个组合。分布于北部的一个组合中土著类型较多，分布于东南部的组合表现出一些与南美东北部及非洲西部鱼类区系的相似性，这种分布格局涉及到南、北两半球的大陆。　 本文对上述分布格局作
