Description

Shell of moderate size, 50-60 mm., elongate fusiform, very slender, with a tall spire and long straight unnotched anterior canal. Adult whorls strongly sculptured with closely spaced long rounded vertical axials, crossed by closely spaced spiral cords which are strongest in the axial interspaces. Sinus subsutural, distinctly notched. Aperture long and narrow. A feature of the genus is the heavy subsutural margining cord, which is rendered strongly nodose by the axials. The genus resembles Amuletum but has stronger axial sculpture and the addition of a prominent nodose subsutural fold. Range Late Cretaceous of the Atlantic and Gulf coastal plains from Maryland to Texas.
