to twenty-five, and on the antepenultimate to about twenty. They gradually diminish in size anteriorly and vanish on the base. On the body whorl there are about seventeen spirals, not counting a few minute interstitial threads. On the penultimate whorl there are three and on earlier whorls two spirals. The protoconch consists of two rounded whorls, superficially smooth, but on high magnification developing faint and minute oblique reticulation. The aperture is imperfect in the only example seen.
