---|---|---|
J. W. Durham 1937 | Shell large, fairly heavy, having about nine well-rounded whorls; sutures deep; ornamented by nine or ten heavy Iamellar varices with interspaces about twice their width; varices curve posteriorly from suture for a short distance and then straighten out; on central portion of body whorl are three rounded nearly equidistant spiral threads with interspaces three to four times their width; on upper third of whorls are about seven closely spaced, rounded spirals tending to become obsolete on later whorls, their interspaces approximately equal in width to the spiral threads; immediately below the three primary spirals are three to four flat spirals with interspaces not as wide as the fiat spirals; indistinct secondary spiral threads may be seen between the three primaries; the spirals pass over varices, making small nodes at their intersection; base of body whorl marked by a prominent keel with varices passing over it; aperture probably round. |
