A superb complete adult with test, developed on both sides and showing 5 whorls. A typical specimen both in terms of size and inflation. The body chamber occupies about 0.7 whorl, shows uncoiling of the umbilical seam and is smooth with some regeneration of ribbing near the aperture. The umbilicus shows the change from wide and shallow on the inner whorls to the step walls and sharp edge of the more involute body chamber. From Jameson Land, E. Greenland.

Size: 128 mm, max width 81 mm
