The remainder are moderately suturally impressed, with a plicate and conspicuous revolving keel just below the suture, a plain space just below this, and then, joining on to the suture below, another carina raised and ornamented with a spiral row of small shining nodules. The body whorl is almost straight, quite smooth, shining, and milky white until the close rows of striae. [3]
