The animals of this genus crawl quickly, and, when 

 contracted, entirely enter their shell, which they close with 

 their shelly operculum. They live in sandy places, hiding 

 imder the surface and burrowing after bivalves, which they 

 pierce with the siliceous teeth of their lingual mem- 

 brane, sucking the juices through their long, retractile 

 proboscis; when they crawl they leave deep traces behind 

 them. They are found in all parts of the globe, though 

 the larger and more showy species are tropical; they have 

 been observed to range from low-water to ninety fathoms.
