Equally rare, and from the same collection as the preceding. In habit it approaches nearest to M. exasperata of Chemnitz, but has not the ribs angulated or their interstices striated, and is much more narrowed at the base than in that shell, which I have seen: the outer lip is also smooth; the inside strongly striated. This shell was formerly in the collection of Mr. Keate, the elegant author of the "Sketches from Nature."
