Considered to be an index species of the Belle Glade Member of the Bermont Formation (Petuch & Roberts, 2007).
"Shell broadly ovate or barrel shape, solid, with a low, conic spire of five and one-half whorls, the protoconch destroyed. The body whorl is large, with even convex sides, widest a little above the middle and without a definite shoulder. The pillar structure is a relatively short and strongly differentiated development and stands prominently above the sharp contraction encircling the anterior end, its lower section with four, narrow, descending plaits, its upper one with two short ones. The siphonal canal notch is deep, its borders coarse and forming a simple, narrow fasciole, its surface depressed by the anterior contraction. A series of about 11 lirae lie over the callus pad along the parietal wall. The inner lip is ridged along its entire length as if by reabsorption, its inner side flattened, the pillar plaits and parietal lirae bending across it in normal fashion. The outer lip margin is straight, except above where it swings into the suture; it is bordered on the back by an accessory band of enamel and on the inside by a ridged shelf. The sutures are narrow and deeply channeled, bordered on the inner side by a ledge of overhanging callus which covers the surface of the spire whorls. Length 47.1 mm., diameter 24 mm.". Pleistocene. Bermont Formation. Spoil bank near Indian Town, Martin County, Florida, USA.
