« This very curious shell was first observed as a fossil by Linnaeus himself, in the pleistocene beds of Sweden. Not until of late years has it been taken alive, and British cabinets were for a long time supplied with specimens from the pleistocene beds of the Clyde. Mr. Smith, of Jordan Hill, was the first to maintain its existence in the living state in the British seas. […] It is a species essentially of northern origin, and has now its chief habitat in arctic and boreal seas, extending along the coast of Greenland, and down those of Boreal America to Cape Cod. It dates its origin from the pleistocene epoch, and can only be regarded as a lingerer in our existing seas. » – Forbes & Hanley: op. cit. vol. II, London 1853, p.475-476.
