 slightly shouldered, flatly convex, base contracted. Suture impressed 

 and margined below by a small thread on the penultimate whorl only. 

 Aperture oblong-oval, margins nearly parallel, produced below into 

 an open slightly flexuous canal, truncated at the base ; sinus obsolete. 

 Outer lip sharp, smooth inside, convex above, concave on the canal.
