perspectively umbilicated; whorls four and a half obliquely, arcuately
striate, compressed, with alternate bands of red and brown;
preceding whorls sunk in and closely embraced by the last,
the base being rather more deeply submerged, and the upper
surface shallower, and more openly perspective; aperture
almost linear-lunate; labrum thin, obliquely produced
towards periphery, and slightly inflated, forming a narrow
groove at the sutures; arch of periphery faintly dilated into
an obsolete keel.
