摘　　要：一、前言本文的“Pseudocardiniidae”包括前人建立的Acyrena,Pseudocardinia,Jiangxiella,Hamiconcha,Kija,Apseudocardinia,Yananoconcha,Hunanella,Xinyuella,Fengjiachonia和Lilingell 11属。其中除Lilingella的壳形、壳饰较特殊外,其余属的壳形、壳饰和内部构造基本上是相同的,其产出层位均在上三叠统至下、中侏罗统。它们分布在苏联的西伯利亚、远东和我国的广大地区。瓣鳃类工作者对它们的研究甚多,如(1937),(1958),(1959)(1958),(1959)The 'Pseudocardiniidae' mentioned in this article include 11 previously established genera, namely, Acyrena, Pseudocardinia, Jingxiella, Hamiconcha, Kija, Apseudocardinia, Hunanella, Yananoconcha, Xinyuella, Fengjiachonia and Lilingella, Except Lilingella which is different in shape and surface sculpture. all the other genera are almost the same not only in shape and surface sculpture but in internal structure as well. And the horizon of Upper Triassic series in which they were found is similar to the Lower—Middle Jurassic series. They are distributed in Siberia, the Far East of USSR and China. Over the past years. many researchers have made lots of studies on Lamellibranchia, including B. I. Chernyshev (1937), I. V. Lebedev (1958), G. G. Martinson (1959), C. M. Kolesnikov (1974), Z. W. Gu et al. (1976), S. Y. Cai and W. Z. Liu (1978), C. W. Xiong and S. Y. Wang (1980), J. H. Chen and M. Y, Xu (1980), J. S. Yu et al. (1980); S. B. Wu (1981), L. Liu and J. H. chen (1981), and Q. H. Ma (1988). In articles, illustrations and books by above mentioned authors, sometimes the very same thing might be given different names, and thus these authors have created many new genera and new species, which greatly affect the deepgoing research of Paleontology and Geology. The present writer takes the Xinhu Formation in Gansu as the ground to illustrate that it is more reasonable to regard the difference in pseudocar(USSR) as synonymous, while the hinge structure and muscle scar system in Jingxiella and. Hamiconcha estabished by the Chinese Lamelibranchia researchers are also the same as in Acyrena, and therefore, they can also be regarded as synonymous with it. Some small lamellibranchs found from the Ziliujing Formation in Sichuan were determined as Pseudocardinia, Tutuella, Utschamiella and Sibireconcha But the writer has found the their shapes, surface sculpture internal structure are all the same as in kija (USSR,). In addition, the internal structure of Apseudocardinia, Yunanoconcha, Hunanella, Xinyuella and Fengjiachonia
