摘　　要：记述江西彭泽、于都、乐平、玉山、崇义及上高等地上石炭统船山组和下二叠统栖霞组的四射珊瑚16种,其中船山组有11属12种(包括8新种、1未定种),栖霞组有3属4种(包括3新种、1未定种).根据珊瑚化石的分布规律,将船山组的珊瑚建立2个组合,并与有关地区的珊瑚组合进行了对比.通过对这些珊瑚形态构造特征的剖析,文章还探讨了晚石炭世晚期及早二叠世早期本区珊瑚的生态特征.This paper deals with the rugose corals obtained from the Upper Carboniferous Chuanshan Formation and the Lower Permian Chihsia Formation (Member I) in Pengze of Leping County, Yudou of Shanggao County, Yushan and Chongyi Counties, Jiangxi Province, which contain 14 genera and 16 species (including 11 new species). I. Protoivanovia-Fomichevella-Arctophyllum-Pseudocarniaphyllum Assemblage, including Protoivanovia penzeensis Zhu, P. dupliformis X. Y, Fomichevella hoeli (Holtedahl), F. longiseptata sp. nov., Arctophyllum jiangxiense sp. nov., Pseudocarniaphyllum jiangxiense sp. nov., Amygdalophyl- loides multiseptatus X. Y, Carniaphyllum gortanii Heritsch, Timania sp. and Chuanshanophyllum sp. Among these corals, Protoivanovia occurring in the lower part of Chuanshan Formation of Anhui and Jiangsu and the Taiyuan Formation of Shanxi was also found in Moscovian and Gzhelian of the Moscow Basin, but the present Protoivanovia penzeensis Zhu is similar to P. lingchuanensis Zhao (1987) from the Taiyuan Formation of Shanxi. Fomichevella which is widely distributed in the Upper Carboniferous of former USSR, is seen in the Dingshan Formation of Jiangsu, the Maping Formation of Guangxi and the Upper Carboniferous of Qinghai in China, but Fomichevella hoeli (Holtedahl) seen in the Gzhelian Fusulina limestone of Spitbergen is first found in China. Arctophyllum is widely distributed in the Upper Carboniferous of northern Xinjiang, Yushu of Qinghai, western Guizhou and southern Jiangsu, but A. jtangxiense sp. nov. is similar to A. intermedium (Toula) (Fedorowski, 1977) from the Teguliferina bed of the Moscow Basin and Gzhelian of Spitsbergen. Pseudocarniaphyllum is known to occur in the Maping Formation of Guangxi and the Chuanshan Formation of Jiangsu, but P. jiangxiense sp. nov. is similar to P. paraorientale X. Y(1977, 1980) from the Chuanshan Formation of Jiangsu. Arnygdalophylloides is widespread in the Upper Carboniferous, but A. multiseptatus X. Y in this paper is also seen in the Chuanshan Formation of Jiangsu. Carniaphy
