the few species that do not exhibit the labral slit of the Pleurotome, the 
short spire of the Pyrule, the transverse columellar plaits of the Turbinelli,

The shell of Fusus may therefore be described as being fusiform, some- 
times of large size, with the spire symmetrically acuminated ; the colu- 
mella, which is smooth, arched, and never reflected, ends in a straight 
canal, varying considerably in length; the aperture is oval, sometimes 
angulated at the upper part ; and the lip is generally crenated, a little in- 
flected, and sometimes striated in the interior. The operculum is horny, 
and acuminated,
