title of Xritonkim, once assigned to them by Muller. These latter, however, 

 I propose to retain in the present genus, together with all those species of

 callosity or denticles, such as the B. undosum and others, added to which I 

 include the Purpura sertum, Francolina, and lageuaria of Lamarck, as well 

 as the Fusus articulatus of the same author. *
