Santa Maria material examined. Maximum height 33.0 mm, width 24.0 mm. DBUA-F 869-1 (1), Ponta dos Cedros, Santa Maria, Azores, Touril Complex, Lower Pliocene.

Description. Shell large, solid, vermiform, irregularly coiled, circular in cross-section. Protoconch not preserved. Azorean specimen solitary (can be several cemented together attached to a substrate, stones or more commonly other shells). Early teleoconch whorls not preserved. Intermediate whorls irregularly and loosely coiled, with frequent changes in direction, marked by opisthocyrt scars, representing the position of previous apertures. Sculpture consists of fine, close-set, granular cords of alternate strength (worn in Azorean specimen). The last whorl straight, hardly coiled, sculpture strengthening toward aperture. Aperture circular, holostomous.
