The trochoidal shell of adult snails is 5.6 mm in height, with a diameter of 7 mm, with a high conical spire, flat sutures and whorls rounded with a keeled edge. It is smooth and pale golden-brown. The umbilicus is narrowly open, partly concealed by the reflected lip of the roundly lunate aperture.
Habitat
The snail is only found on the southern end of the island, on the summit of Mount Gower and nearby ledges.
