Shell elongate-ovate. Periostracum where present pale straw- 

 color. The nuclear whorls are dark, although the last one has the 

 posterior half light. The postnuclear whorls are bluish white. They 

 have a dark blackish-brown band at the summit and another at the 

 periphery that usually shows about as far above the suture as the 

 summit band is below it. The umbilical area also is of the same 

 blackish-brown color. All these bands show within the aperture. 

 The aperture, barring the brown bands, is bluish white, and so are the 

 peristome and columella.
