The limestones of ltaborai Basin (Middle Paleocene), Rio de Janeiro, Brazil, harbor a rich fossil fauna of pulmonate snails. Here two new pulmonate species are described: Brasilennea guttula sp. nov. (Cerionidae) and Eoborus rotundus sp. nov. (Strophocheilidae). B. guttula is the third species of its genus endemic from Itaborai, characterized mainly by its conspicuous shell shaped like a "water drop", with an acuminated spire. E. rotundus is the second of its genus from ltaborai, characterized mainly by its rounded outline and its relative small size. Moreover, a record of Plagiodontes aff. dental us (WOOD 1828) (Orthalicidae) is presented here for the first time for Itaborai Basin.
