[1] Fossils have been found in Quaternary strata of Florida, USA; age range: 2.588 to 0.781 Ma The length of the shell attains 15 mm.

They are strongest on the base, but are generally so faint as not to interrupt the apparent smoothness of the surface nor to be perceptible without a lens.

The fasciole is narrow, excavated, smooth except for lines of growth and the undulations due to the ribbing.

The transverse sculpture consists of rather faint growth lines and of (on the body whorl 12) strong, stout rounded ribs, strongest in front of the fasciole where they end bluntly, extending across the whorl and disappearing only on the siphonal canal.

[3] This marine species occurs from North Carolina, USA, to Puerto Rico.
