The Mur ex covered with large , thick tubercles. 
This is a fmall fpecies, but the tubercles on it are remarkably large: It is rarely 
more than an inch and a quarter in length, and is equal to that at lead: in diameter,

number of volutions: the tubercles are arranged in four or five feries, and are large
