摘要
讨论了包珊瑚科（ＡｍｐｌｅｘｉｄａｅＣｈａｐｍａｎ１８９３）的分类。把包珊瑚型隔壁限于仅在外端连续，向轴部变薄呈短而低的脊状，纵向呈不连续的着生于横板之上。包珊瑚型隔壁的微细构造以层状骨骼为主，其轴部有时可出现非晶榍型纤状骨骼，包括晶粒和短轴晶柱。泡沫珊瑚型隔壁由全晶榍，杆晶榍和复式杆晶榍组成。据此易于和包珊瑚型隔壁区分。包珊瑚科以具包珊瑚型隔壁为特征。有１０个属可归入该科，它们是：Ｅｓｔｏｎｉｅｌａｓｍａ，Ｐｉｌｏｐｈｙｌｉａ，Ｓｙｎａｍｐｌｅｘｏｉｄｅｓ，Ｌｉｎｄｓｔｒｏｅｍｏｐｈｙｌｕｍ，Ａｍｐｌｅｘｏｉｄｅｓ，Ｐｒｏｔｏｐｉｌｏｐｈｙｌｕｍ，Ｓｉｐｈｏｎｏｐｈｒｅｎｔｉｓ，Ａｌｔａｉｏｐｈｙｌｕｍ，Ａｍｐｌｅｘｕｓ，Ｂｏｒｄｅｎｉａ。还对Ｅｓｔｏｎｉｅｌａｓｍａ，Ｓｙｎａｍｐｌｅｘｏｉｄｅｓ，Ｓｉｐｈｏｎｏｐｈｒｅｎｔｉｓ，Ａｌｔａｉｏｐｈｙｌｕｍ和Ｂｏｒｄｅｎｉａ作了讨论，并提出了包珊瑚科中一些属之间可能的亲缘关系。
This paper deals with taxonomy of the Family Amplexidae Chapman(rugose coral).Amplexoid septa are longitudinally continuous only on peripheral parts,but become attenuated and discontinuous in the axial part,occurring as short low ridges on upper surfaces of tabulae.They may be composed entirely of lamellar skeleton,or with axial ends containing non trabecular fibrous granules and brachycolumns. Amplexoid septa are similar to cystiphylids in some aspects,but the latter are composed of holacanth,rhabdacanth,and composite rhabdacanth,which are absent in the former.The Family Amplexidae contains 10 genera,namely, Estonielasma,Pilophyllia,Synamplexoides,Lindstroemophyllum,Amplexoides,Protopilophyllum,Siphonophrentis,Altaiophyllum,Amplexus, and Bordenia. Here diagnosed are the genera Estonielasma,Synamplexoides,Siphonophrentis,Altaiophyllum, and Bordenia with brief discussions.In addition,the relationships between some genera included in this family are proposed based on new interpretation of the structures.
