Description (Original description) The subglobose spire is elevated. It contains five convex whorls, sloping on the sides and obliquely truncated above. The body whorl is sub-compressed, most convex above, its width about equal to the length of the aperture. The aperture is narrowed above, wide below and rounded anteriorly. There are two folds on the columella: the upper one heavy and rounded, the lower or anterior one, obsolete. The columellar edge of the body whorl in one of the casts is marked by acute-angular striae, one branch extending directly upwards on the outside of the whorls (inside of the shell), and soon becoming obsolete. The other branch runs into the columellar cavity.Gabb, W. M. (1862). Descriptions of new species of Cretaceous fossils from New Jersey, Alabama and Mississippi.

Distribution Fossils of this marine species have been found in Cretaceous strata in New Jersey, USA.
