A study about the herpetological legacy of the German naturalist Andreas Mayer (1907-1986) (Bérnils & Moura-Leite, 1990) raised 83 specimens from 20 reptile species captured in the Brazilian states of Paraná and Mato Grosso do Sul (years 40, 50, and 60) and currently housed at the Museu de História Natural Capão da Imbuia (Curitiba). Just in Mayer's birth centenary, 15 more snakes collected by him and not presented in the former publication were founded. This material is relevant because (1) came from areas currently under human-altered environments; (2) was collected in areas that were poorly sampled at that time; and (3) embraced some species hard to find in Paraná, including the first occurrence of Phimophis cf. guerini for the state. Label data for the added snakes and some important corrections to the former article, with taxonomic and geographic updates, are being presented.
