J. W. Durham 1937 | Shell large; whorls convex, sutures moderately deep; axial ribs prominent; varix-like, not passing regularly fromwhorl to whorl and not extending on to basal disk; fairly prominent spiral ribs crossing axial ribs; basal disk with fine spiral ribs and peripheral keel; aperture nearly circular, inner lip thin; a small anterior auricle present. | |
R. L. Squires and L. R. Saul 2003 | Whorls joined and not umbilicate. Basal keel visible on spire supradjacent to suture. Axial ribs not crossing basal keel. Spiral sculpture fine, covering whorl sides. Basal disk with fine spiral threads, crossed by radiating slightly sinuous growth lines (Saul & Popenoe, 1993). |
