Addendum to the type catalogue of the malacological collection in the Museu de Ciències Naturals de Barcelona

The catalogue of type specimens of molluscs of the Museu de Ciències Naturals de Barcelona, published in 2008, is updated with new material corresponding to 42 species and subspecies of continental molluscs from the Iberian Peninsula, the Balearic Islands, and the Canary Islands. Most of these type specimens belong to historical collections of the Museum or are part of the malacological collection of Miquel Bech, donated in 2009. Information provided includes the type category, number of specimens, geographic provenance, type specimens housed at other institutions, and current taxonomical status, together with supporting texts of nomenclatures if pertinent. The catalogue also includes a brief gallery of photographs of types per taxon.
