Historical type collections are an important tool in biodiversity research and help to understand taxa if their data are presented with their label information, thus providing a context for taxonomic research. This paper is part in a series undertaken under the SYNTHESYS programme to document the types of Orthalicoidea (Mollusca, Gastropoda) taxa in major European museums, in this case the Museum f?r Naturkunde Berlin. Information on type material of 96 taxa is presented; together with references to previous documentation, all 238 types of Orthalicoidea types extant in the Berlin museum are indexed. Also a list of relevant correspondence in the Handwriting Archive is presented.
