摘　　要：文中报道的拉氏大眼蟹化石(Macrophthalmus latereillei),产自浙江瑞安上望地区海滨泥塗,为新近纪全新世的化石遗体。从沉积环境分析,进而证实这是一类穴居于海滨沿岸沙泥滩的类型。它为我国稀有的蟹类化石增加了新的记录。为探讨与周缘地区蟹类动物群的关系提供了线索。Two specimens of a fossil crab(Macrophthalmus(Venitus) latreillei Desmarest,1823) from the Holocene of Zhejiang,SE China are described and figured.They were found in sandy mud-flats of the lower reaches of the Feiyun River near Shangwang town,Ruian County,Wenzhou City.The fossil crab described herein are housed in the Natural Museum of Zhejiang in Hangzhou(Cat.No.M1492A,B).In China,Macrophthalmus(Venitus) latreillei has been reported in marine sediments of the Holocene Guanghai Group in Moyangjiang estuary,Guangdong Province.The fossil-bearing beds dates from 5 500 years to 8 000 years by 14 C method on shell materials from Moyangjiang(Yang and Wang,1985).The living Macrophthalmus inhabits the coast of an inland sea and river mouth on mud or sandy mud-flats(Sakai,1939).The crab specimens of Zhejiang are preserved in grey sandy mudstones indicating a habitat of sandy mud bottom.The discovery of Macrophthalmus in Zhejiang expands the palaeogeographical distribution of the genus and helps to understand the relationship of Holocene crabs among Guangdong,Hainan Island,Taiwan,as well as Indian-pacific area.
