Description. "Shell large, some specimens apparently attain- 

 ing a length of 4^ inches, with a diameter of the largest volu- 

 tion of rather more than ij4 inches; spire short, or only mod- 

 erately elevated, although the general form of the shell is some- 

 what slender, the body volution, as viewed on the apertural side, 

 forms fully four-fifths of the entire length, even in the condi- 

 tion of internal casts ; upper volutions compact, convex on the 

 sides, and rather squarish or suddenly rounded to the suture 

 on the top; body volution very large and very gracefully swollen
