Description. — Shell turbinate, pyramidal ; spire of four or five mode- 

 rately- ventricose whorls ; apical angle between 65"^ and TO'* ; base convex.

 the umbilicus nearly flat, all of them exposed to the apex. Surface 

 obscurely striated parallel to the edge of the aperture, the latter obscurely 

 rhomboidal. 



Length of the largest specimen 10 lines ; width 9 lines.
