REMARKS

The two specimens correspond well to the original description. The larger specimen closely matches the illustration in shape and corresponds closely, depending on the orientation of the measurements, to the actual dimensions given in the description (height 23 mm [error, since it cannot be smaller than the aperture height; correctly possibly 33 mm], width 30 mm, aperture height 26 mm, aperture width 17 mm), having respective dimensions of 34.6, 32.6, 26.1, 17.1 mm. There is also a label characteristic of Morgan’s collection. We therefore designate the larger of the two specimens as the lectotype to stabilise the name.
