The data regarding the Romanian herpetofauna are very scarce. The most comprehensive studies in this field are included in the volumes Fauna R.P.R. Amfibia (Fuhn 1960) and Reptilia (Fuhn & Vancea 1961). However the researches didn’t satisfactory cover the surface of Romania so the herpetofauna of Bacãu County was less studied (ªova 1968, Ghiurcã 2004). Concerning these issues we aimed to realize a synthesis of the knowledge regarding the herpetofauna from Bacãu County, based both on the previous studies and our field researches.
