Description
{A smooth form with flatter whorls, 40 to 100 mm in length, but a highly variable species that occurs in several morphologically different geographical and bathymetrical forms; these forms may look identical over large areas, then give an impression that several near species are involved. Cf Revision of the Northeast Atlantic bathyal and abyssal neogastropoda, by Ph.Bouchet}
Distribution
{It lives on sand to mud bottoms, between 50 to 1500 m, from northern Norway to Portugal. A species frequently accidentally fished by fishing trap fishermen from the Channel and the Bay of Biscay, such as those from the port of Conquet in Brittany; this fishing trap fishery is the only one that brings this difficultly accessible species back to land. See Bouchet and Waren 1985. See also European Seashells Vol.1, from Poppe and Goto 1991.}
