On the discovery of a new volutopsius (Gastropoda, Buccinidae) from the North-Eastern atlantic ocean

摘要

During an ongoing research programme to investigate fishing grounds on and around the Rockall Plateau and along the continental slope to the west of Scotland the scientific staff on board of R/V Scotia collected a number of Mollusca as a by-catch, among them several Buccinidae. Two of the larger species deserve more attention: Beringius bogasoni Warén & Smith 2006 and specimens of an unknown Volutopsius. The latter can be distinguished from Volutopsius norwegicus (Gmelin 1791) by the spiral sculpture and is added to the British Fauna as Volutopsius scoriae sp. nov.
