brown periostracum; whorls 5, the last somewhat convex, 
marked with oblique, rather coarse growth-ridges; suture im- 
pressed, erenellated by the terminations of the transverse erowth-

Sheli perforate, depressedly turbinate, rather thin, pale yel- 
lowish ; whorls 5, marked only with irregular, oblique, arcuate 
growth-lines ; suture impressed ; umbilicus rather broad, open 
deep; columella margin outwardly expanded above, descending 
in a curve; labrum simple; aperture compressedly ovate.
