The genus Pseudocypraea Schilder, 1927 (Gastropoda, Cypraeoidea, Ovulidae) was previously known by the living type species Pseudocypraea adamsonii (Sowerby, 1832) from Indo-Pacific Province, Galapagos and Coco islands and by the deep-water species Pseudocypraea exquisita Petuch, 1979 from the Philippines and South Africa. Pseudocypraea dolini n. sp. is described here from the Bartonian (Marinesian, middle Eocene) of Le Quoniam (Haravilliers, Val d'Oise, France). Pseudocypraea eratoformis (Hoernes & Auinger, 1880) n. comb. is also proposed for Cypraea (Cypraeovulva) eratoformis Hoernes & Auinger, 1880 from the Langhian (early Badenian, middle Miocene) of Lapugiu de Sus ("Lapugy", Rumania). These two fossils confirm the diagnostic characters of Pseudocypraea, hitherto only based on the two extant species. The total number of species is now raised to four and the geographical distribution of the genus enlarged.
