* This genus was established by Lamarck for V. bulloides, and if 

 restricted to the well marked group of which that is a type, may well be 

 retained. But as he afterwards employed it, in Anim. sans Vert., it em- 

 braced a large number of species, which most writers, since his day have 

 referred to Marginella.
