In August 2021, the State Museum of Natural History in Lviv received the conchological collection of the geologist and amateur collector I.T. Bakumenko. This made it possible to considerably supplement the sample of exotic mollusc species, mainly marine ones, intended for exposition use. During the processing of the collection, the existing identifications were checked, and most of the unlabeled specimens were also identified. Unfortunately, the vast majority of materials did not contain data on place and time of collecting, so they could not be transferred to the main fund of the museum. Most of the collection was represented by the shells of exotic marine molluscs, the list of which is given in the article. Excluding materials identified only to genus or subgenus level, the collection transferred to the museum contained 6 species of exotic land molluscs and 145 species of exotic marine ones. Most of them have previously not been presented in the malacological collection of the museum. Without taking into account taxa whose correct identification requires additional verification, three species of land exotic molluscs, one family (Pinnidae) and 86 species of marine exotic ones appeared for the first time in the malacological collection. Some shells of exotic molluscs of the families Arcidae, Ampullariidae, Cardiidae, Mactridae, Muricidae, Naticidae, Orthalicidae, Ostreidae, Patellidae, Pectenidae, Ranellidae, Tellinidae, Trochidae, Veneridae require further identification. Some of the most attractive examples of the collection transferred to the museum were demonstrated in a thematic electronic photo album “Treasures of distant seas” (2021). In the future, the digitization of other exotic species that entered the malacological collection of the museum for the first time is planned. The produced photos will be used in one of the thematic sections of the museum project Educational Internet program "Molluscs".
