The recent occurrence of four species in the Dutch part of the North Sea is reported. The gastropods Vitreolina antiflexa (Eulimidae) and Ondina divisa (Pyramidellidae) are entirely new to the Dutch malacofauna. For the bivalves Semierycina nitida (Erycinidae) and Altenaeum dawsoni (Condylocardiidae) only records of empty shells are known.
