摘　　要：报道河南郑州三李西沟更新世马兰组、潞王坟组的腹足类化石４种：Ｐｈｙｓａａｓｓｕｔｕｒａｌｉｓｓｐ．ｎｏｖ，Ｉｎｄｏｐｌａｎｏｒｂｉｓｅｘｕｓｔｕｓ（Ｄｅｓｈａｙｅｓ），Ｃａｔｈａｉｃａ（Ｐｌｉｏｃａｔｈａｉｃａ）ｒｉｃｈｔｈｏｆｅｎｉ（Ｍａｒｔｅｎ），Ｃ．（Ｅｕｃａｔｈａｉｃａ）ｆａｓｃｉｏｌａ（Ｄｒａｐａｒｎａｕｄ）。认为潞王坟组沉积时的水域可能比马兰组沉积时广宽，其时代归入早更新世，沉积环境与现代相似，气候比现代温暖。The Pleistocene gastropods under study were collected from Zhengzhou,Henan,with 3 genera and 4 species(including I new species).Among them,Cathaica (Eucathaica)fasciola and Cathaica (Pliocathaica) richthofeni were collected from the Malan Loess of Late Pleistocene Malan Formation,while Physa assuturalis sp.nov.,and the living species indOPlanorbis exustus and Cathaica(Eucathaica) fasciola were collected from the yellow pink mudstone of Early Pleistocene Luwangfen Formation.Since Physa assuturalis is a new species,while Cathaica(Eucathaica) fasciola is discovered in two beds(Malan and Luwangfen Formations),it can be clearly seen that these faunas are closer to the Pleistocene species,and the Luwangfen Formation may belong to Early Pleistocene instead of Tertiary.
