The shells of this genus are marine, inhabited by mollusca, 

 that, by frequently moving in and out of the shell while 

 wandering on the shore in search of food, produce singular

 resemble the Murex and Buccinum, but are distinguished 

 by a thickened marginal lip on the right side. 



Shell ovate, spire produced ; aperture sinuous, terminated 

 at the base by a very short canal ; straight, and without a 

 notch ; columellar edge callous and effuse ; right edge with 

 a thickened varix.

 tions flattened and nodulous ; cream-coloured, with undu- 

 lated, brownish-yellow longitudinal lines ; interior of lip
