摘要：Two non-native muricid gastropods are known from The Netherlands since 2007, i.e. the American oyster drill Urosalpinx cinerea and the Japanese oyster drill Ocinebrellus inornatus . Both species reproduce and slowly increase their area of distribution. Eight vacant shells of another non-native muricid, Hexaplex trunculus , have been collected in 2007, 2008 and March 2009. The latter species from southern Europe has recently been observed along the western coast of Europe in areas of shellfish culture. Vacant shells of Haustellum brandaris and Ocenebra erinacea , two more non-native muricids, have been collected as well.
