J. W. Durham 1937Shell large, moderately heavy; about eight or nine slightly convex whorls; ornamented by 13 to 14 moderately heavy varices which are reflexed against those of preceding whorl with deposition of a slight amount of callus between them; varices varying in width from as wide as high to twice as wide as high, usually rounded; spirally ornamented by six or seven equidistant rather promi- nent rounded threads, with interspaces about one and one-half times as wide as the threads; these spirals in passing over the varices produce a moderately prom- inent node on top of the varix; basal keel not prominent; some evidence of spirals of the same size and spacing below it; aperture ovate.
