摘要
中国海软体动物的种类相当丰富,但是在解放前,对这些种类进行研究的却很少。在国内仅有葛利浦和金叔初(1928),金叔初和秉志(1931—1936),秉志和阎敦建(1932),阎敦建(1933,1935,1936,1942),张玺(1934,1936,1937,1940)的一些报导。
The molluscan fauna of our seas is rich both in species and in quantity.Before the liberation,there were only a few published reports concerning certain molluscan groups of certain regions.Up to now,the demarcation of Chinese molluscan faunal regions is still poorly investigated.The material for the present study was collected during the last ten years or more.The principal results may be summarized as follows:1.The Chinese marine molluscan fauna is made up of 3 components:(1)a boreal element which is composed of a few northern species occurring only in the Yellow Sea and Pohai;(2)an Indo-West-Pacific element which is composed of great number of southern species,some of which are widely distributed along our coasts,others are restricted to the East and South China Sea or only to the South China Sea;(3)an endemic element of the Sino-Japanese region,which includes some temperate species occurring only in the Yellow Sea and in the waters of northern Japan,and warm-water species occurring in the East and South China Sea and in waters of southern Japan.2.As a result of analysis of the distribution of the members of 35 warm water families and of certain temperate and pure tropical forms,we were able to delineate the following molluscan faunal regions of our seas:(1)a warm temperate region which includes the Yellow Sea and Pohai;(2)a subtropical region which includes the East China Sea,the north-western coast of Taiwan and the northern coast of Hainan and(3)a tropical region including the south-eastern coast of Taiwan,the coast of the southern tip of Hainan Island and the area south of them.3.Based on the distribution around Japanese waters of some species,some of which in our waters have restricted their northern limit of distribution at the mouth of Yangtze river and its adjacent area and others at the southern tip of Hainan Island and Paracel Islands,we are inclined to infer that the northern boundary of the subtropical molluscan fauna of Japan lies near Chosi,east of Tokyo,on the oceanic side and about Noto peninsula on the Sea of Japan,While its southern boundary lies near Amami-Oshima,slightly north of Riu Kiu Islands(see tables 3-5).4.The marine molluscan fauna of China,compared with that of adjacent waters,is closely allied with that of Japan.The results of quantitative analysis of species belonging to eight families show that a great number of our species occur also in the waters of Japan(see table 1).5.According to the resemblance of the components of the Chinese and Japanese molluscan fauna,it seems better to consider that within the subtropical regions of China and Japan there is an independent zoogeographical unit,which is a part of the Indo-West-Pacific region and may be designated as Sino-Japanese subregion.The areas south of it,such as the coasts of the southern tip of Hainan Island,south-eastern Taiwan and the Paracel Islands,should belong to the tropical Indo-Malayan subregion.The Yellow Sea,Pohai,the northern Japanese coast and regions north of it may belong to the Far East subregion of the temperate North Pacific region(see fig.2).
