Much more lengthened and with more whorls than C. Vertagus, 

 less swelled in the middle, very slightly grooved, and white-

The numerous longitudinal ribs arc serrated by the spiral

 these points are formed into a more prominent rib at the lower 

 part of the last whorl. The lineated variety of this species is rare.
