Nassa, Martini. 



The foot of Nassa is large and bifurcate behind. The shell has a smooth callous 

 base, with a short anterior canal. The animals are active, and crawl vivaciously over 

 mud and sand in search of bivalve shells, which they pierce with their proboscis (the 

 radula acting as a drill), and extract the animal through the aperture, which is usually 

 made near the beaks, and rarely if ever near the margin.
