This genus is not given by De Blainville precisely like 

 Lamarck, as he has removed those that are greatly canal- 

 iculated either to the Murex or Turbinella. They are all 

 marine shells, and greatly approximate the last-mentioned 

 genus. 



Shell oval, globular, ventricose, rugged ; the spire mid- 

 dling, pointed ; aperture ovate, enlarged, grooved, and some- 

 times sub-canaliculated anteriorly ; the right edge effuse, 

 concave, sharp ; the left or columellar edge almost straight, 

 and marked in the middle by two or three plaits ; operculum 

 horny,
