A thorough collection effort recently took place at Pedra Talhada Biological Reserve (Reserva Biológica de Pedra Talhada, in Portuguese) in Alagoas state, one of the largest fragments of Atlantic Forest in northeastern Brazil. The expedition recovered hundreds of land snails and this material is fully reported and described herein. Forty-two species were found in the reserve (47 counting historical records), com- prised mostly of stylommatophoran snails, although some species of Neritimorpha and Caenogastropoda were also found. Many of these species are recorded here for the first time from Alagoas state, extending the geographical range of some or filling distribution gaps of others. The generaBothriopupa and Sterkia, both vertiginids, are reported here from Brazil for the first time. One important find is Megalobulimus cardosoi, which was deemed extinct in the IUCN Red List.
