 Shell about sixteen lines long, and six broad in the middle of 

 the body-whirl, and rather more than half as broad at the 

 truncated summit ; it has four or live white longitudinally

 had been broken off. Bruguiere has given a long account 

 of this species, and endeavoured to account for its strange 

 formation.
