Genus MANGELIA, Leach. 



Shell solid, fusiform, smooth or longitudinally ribbed ; 

 aperture linear, with scarcely any canal in front ; columella 

 smooth, simple ; outer lip acute, with a slight sinus poste- 

 riorly, near the suture. 



Si/n. Raphitoma, Bell.

The genus most likely to be confounded with Mangelia 

 is Cythara of Schumacher, from which, however, it may 

 readily be distinguished by the spire being longer than the 

 aperture, by the columella being smooth and not trans- 

 versely corrugated, and by the outer lip being thin and not 

 crenate internally. There are many recent species, chiefly 

 from tropical seas.
