 uous ; spire depressed, with blunt, rather large apex ; whorls 4, sep- 

 arated by an impressed, rather irregular suture ; body-whorl large, 

 transversely widened, somewhat inflated, rapidly and rather strongly 

 deflected anteriorly ; aperture oblique, ovate, shining and white 

 within, and showing the bands ; peristome simple, sharp, straight, 

 labiate with, white within ; columella rather straight, scarcely ex-

The form above described and figured differs from the species as 

 defined by Albers in being distinctly, instead of " snbtilissime" stri- 

 ate, and in its greater altitude. The measurements given by Albers 

 are : diam. 29, alt. 18 mill.
