We are acquainted with two shells, perfectly distinct as species, yet sufficiently alike to render Lamarck's description of his M. melaniana applicable to both. In this uncertainty, we at first intended to distinguish this by the name of carbonaria, and to consider the other as Lamarck's melaniana, but further consideration induces us to alter this arrangement; the second species we propose to illustrate in an early number. Our figure was taken from a full-sized specimen, received from Australia, and now in the Manchester Museum.
