中国近海蟹守螺科(Cerithiidae)两新纪录种及常见种名修订

摘要

Two new record species of Genus Cerithium Bruguiere from China seas were found in a systematic research on the Family Cerithiidae.All the specimens were collected by the Institute of Oceanology of the Chinese Academy of Sciences since 1950.The two new records were Cerithium novaehollandiae Adams in Sowerby,1855 and Cerithium scobiniforme Houbrick,1992.The two species were distributed in the coastal areas of Hainan Province.The morphology of shell,flesh,and operculum,and the habits and geographical distributions of the two new record species are discussed and compared with those of the similar species.In addition,a revision of the common names of Family Cerithiidae in China seas is made.%在系统整理研究中国科学院海洋研究所历年来在中国近海采集的蟹守螺科标本时,鉴定出属于蟹守螺属(Cerithium)的中国两新记录种,分别是:阶梯蟹守螺Cerithium novaehollandiae Adams in Swoerby,1855和锉形蟹守螺Cerithium scobiniforme Houbrick,1992.两新记录种分布于中国海南省沿海,栖息于潮间带至浅海的岩礁、砂或石砾质海底.文中对两新记录种的外部形态、软体部、厣特征和习性及地理分布等方面进行了论述,并与相似种进行了比较.且对中国近海蟹守螺科一些常见种名进行了修订.
