s are convex and encircled by strong spiral ribs. The interstices between them are deeply, coarsely pitted by the prominence of strong, regular, longitudinal lamellae, continuous over the spirals. The penultimate and next earlier whorls have 3 spirals (the subsutural one sometimes subobsolete). The outer lip is inserted upon the fourth. On the
