Description (Original description) The fusiform shell is turriculate. It contains 10 whorls, the lower half obtusely ribbed. The upper half are concave, subangular, with much curved, rugose lines of growth. Beneath the suture whorls are obtusely subcarinated, with distinct revolving lines over the ribbed portion, minute and obsolete above it. The suture is profound. The body whorl and the aperture are striated. The aperture is slightly curved.T.A. Conrad, Descriptions of New Genera, Subgenera and Species of Tertiary and Recent Shells; Proceedings of the Academy of Natural Sciences of Philadelphia, Vol. 14 (1862), pp. 284-291]
Distribution Fossils of this marine species were found in Miocene strata of Delaware, United States; age range: 20.43 to 15.97 Ma.
