摘　　要：云南省昭通市东北郊箐门出露了一条比较完整的泥盆纪浅海相地层剖面,下、中、上三个统均有出露,浅海底栖生物化石丰富,研究基础也相对较好,是研究滇东北地区泥盆纪地层的一条理想剖面。由于地层剖面比较长,沉积厚度比较大,文中仅描述该剖面早泥盆世和中泥盆世早期的四射珊瑚,并讨论有关地层划分和珊瑚群古生物地理亲缘关系。The rugose corals described in the present paper were collected by one of the authors （Liao Weihua） from the Qingmen section of Zhaotong, NE Yunnan in 1972. These corals, occuring in association with brachiopods （Rostrospirifer ardenensis, Rostrospiri f er tonkinensis , Acrospiri f er orthogonalis, Acrospirifer lungmenshanensis, Atrypa sp., Cyrtina sp., ＂Delthyris＂ sp., Dicoelostrophia beblistriata , DicoeZostrophia punctata , Elyta sp., Eosophragmophora sp., Howittia sp., Howellella sp. , Kwangsia cf. yohi, Mesodouvillina orientalis, Nadiastrophia pattei, Parachonetes nasutus, Parathyrisina tangnae, Schuchertella sp. ）, Stromatoporoids （Clathrodictyon sp., Anostylostroma sp. , Atelodictyon sp. , Ferestrom-atopora sp. ）, and bivalves （Leptodesrna ？ sp., Mytilarea sp. ）, were found in a series of sandstones, mudstones intercalated with marls or argillaceous limestones. The rugose corals described and illustrated comprise 11 species within 8 genera. They include two rugose coral Assemblages in ascending order ： The first rugose coral Assemblage （Early Devonian Emsian） ：Acanthophyllum cf. guitangense Yu et Liao Australophyllum cyathophylloides Hill Calceola intermediata intermediata YohCalceola sandalina nanningensis Yoh Cystiphylloides cf. fongi （Yoh）Cystiphylloides mirabiLe Wedek：nd et Voll-brechtEdaphophyllum zhaotongense sp. nov. Tryplasma cf. guangxiensis Yu et Liao Xystriphyllum cf. The second rugose Devonian Eifelian） ; devonicum Bulvanker coral Assemblage （Middle Devonian Eifelian） ;Utaratuia yunnanensis sp. nov. X ystriphyllum h yperbolicum Crickmay Among the first rugose coral Assemblage, Acanthophyllum cf. guitangense and Tryplasma el. guangxiensis have been recorded from the Lower Devonian （Emsian） Guitang Formation of Guangxi, Calceola intermediata intermediata and Calceola sandalina nanningensis have hitherto been known from the Lower Devonian （lower Em- sian） Yukiang Formation of Guangxi and the Pochiao Formation of SE Yunnan respectively.
