A fine complete adult phragmocone with test developed on both sides showing the highly globose cadicone form with very inflated rounded whorls. The primary ribs have umbilical tubercles and the fine secondaries cross the venter, fading over the last 1/2 whorl which is almost certainly the body chamber. The umbilical seam uncoils strongly over the last 1/3 of a whorl and the body chamber has a terminal constriction and complete peristome on both sides and the venter. From Minchinhampton, Gloucestershire.
