The identification of this species often causes some difficulties, as a number of geographical species or varieties have been grouped round the tvpe species Crania anomala (Mull.), and distincl specific characters mav lie difficult to discern in these related forms. The type species, however, originates from the Norwegian west coast and from Scotland, and there is no doubl thai the specimens at hand belong to the North Atlantic Crania anomala (Miill.). The 31 living specimens from "Michael Sars" St. 64 are of special interest since on account of the thickness of the shells and the complete absence of the embryonic shells (protegulum), they must be of considerable age. All of them have been loosened from their supports and in all of them the ventral shell is missing. They differ much in size, the largest is is mm â 25 mm, the smallest '.I mm â II mm, the breadth being greater than tic length. The dorsal or upper valve is smooth, very thick, its inner side chalk-white whereas the outer side is covered with a tough, rusty-red periostracum which in some specimens is tattered. The apex is slightly developed, direct
