| Abstract |
A small gastropod, closely related to a couple of species known from moderately deep water in theMediterranean, is described as a new species based on nine specimens. The snails were found in fourgrab samples, one on a sandy-rocky bottom in outer Sognefjorden, two on silty-sandy bottom in outerHardangerfjorden, both from 34 m, and finally one from 54 m depth outside Sotra, W of Bergen. Thisis the first record of a member of the heterobranch family Xylodisculidae from Norwegian waters.The specimens were all found in the immediate vicinity of salmon farms, and a preference by thespecies for the reducing environment of decaying, surplus fish feed is suggested. |
