An overview on the type series of freshwater mollusk species and varieties described by Jacques Philippe Raymond Draparnaud (1772–1804) in 1801 and 1805 was published by Vinarski & Eschner (2016). In total, 22 out of 23 gastropod and bivalve taxa were presented with relevant information on species identity, synonymy and taxonomic position. This addendum is completing the information on freshwater mollusk species with one additional gastropod type series and two type series, which were not mentioned in the previous paper. Moreover, to complete this examination, two neotypes are depicted, as the corresponding specimens in the Draparnaud Collection are not valid. New and high quality photos with natural colour balance are given for all type series of altogether 23 freshwater taxa.
