中文摘要：

云南省华宁县盘溪地区的泥盆纪浅海相地层发育，珊瑚化石丰富，研究历史悠久，是中国南方重要的泥盆系剖面之一，它在国内外地层古生物学界久负盛名。1948年王鸿祯教授首次描述了盘溪等地泥盆纪的四射珊瑚19属36种（包括变种、未定种等），其中有19新种，自下而上建立了G、C、K、E、T、P、D等7个珊瑚层（horizon），奠定了滇东泥盆纪生物地层研究的基础，该文至今仍一直被国内外地层古生物学界同行所引用和参考。文中描述了盘溪泥盆纪四射珊瑚13属13种（包括未定种和近似种）及其上覆下石炭统的四射珊瑚1属2种。文章还着重讨论了泥盆系的南盘江组、一打得组和在结组的地质时代以及泥盆石炭系界线等地层问题。

英文摘要：

Eastern Yunnan, southwest China, especially the Panxi（Poshi） area, has been one of the most important areas for the study of the neritic Devonian in South China. Fossiliferous Devonian deposits in the Panxi region have been well known for a long time. The Devonian in the Panxi section is mainly composed of carbonate rocks, which contain abundant benthic fossils （rugose corals, stromatoporoids and brachiopods）. Significant biostratigraphic works on these Devonian rugose corals have been made by Wang Hong-zhen, who assigned them to 36 species in 19 genera, including 19 new species. He subdivided them into 7 horizons （in ascending order： G, C, K, E, T, P, D）. The rugose corals described and illustrated in this paper comprise 15 species within 14 genera： Cystiphylloides tungshanensis （Wang）, Mesophyllum panxiense （Yu, Liao Deng）, Dendrostella trigemme , Neosyringaxon huaningense sp. nov.,Endophyllum panxiense sp. nov., Grypophyllum tenue Wedekind, Disphyllum sp., Spinophyllum？ hejiazhaiense（Kong in Kong ＆ Huang）, Temnophyllum waltheri Yoh, Truncicarinum temeniophylloides （Wang）, Pseudozaphrentis cf. di f ficile Sun, Thamnophyllum sinense Yu, Liao ＆Deng, Mictophyllum intermedium Liao, Axophyllum vaughani longiseptatum Wu ＆ Zhao, Axophyllum zhanyiense Wu ＆Zhao. Among them, Grypophyllum tenue, Temnophyllum waltheri, Thamnophyllum sinense, Cystiphylloides tungshanensis and Spinophyllum？ hejiazhaiense, the species in the Kutsing and Poshi Formations, as well as the genera Endophyllum and Neosyringaxon are characteristic of the Givetian in South China, Russia and Germany. Pseudozaphrentis difficile and Mictophyllum intermedium, the former is from the upper part of the Itate Formation and the latter is from the Zaijie Formation, usually recorded from the Frasnian of South China. Dendrostella trigemme, from the Nanpanjiang Formation,is commonly found in the upper Eifelian to lower Givetian. The overlying strata yield Lower Carboniferous corals Axophyllum zhanyiense and Axophyllum v
