Etymology

Original Description:

Shell depressed-globose, wrinkled, below smooth; spire short, depressed; suture moderate; whorls five, rapidly increasing, the last very ventricose and large, sometimes marked with coarse revolving lines; aperture large, round, lip simple, acute, ends approached, joined by a slight and deep umbilicus.
It is a much larger and more globose shell than H. fuliginosa, Binney, with a smaller umbilicus, more rounded and larger aperture, and more ventricose body whorl; its color is also lighter. The revolving lines are present in four out of six specimens before me.
