Description
editThe shell of adult snails is 17–21 mm in height, with a diameter of 31.9–34.8 mm, subglobose with a moderately raised spire, with rounded whorls, impressed sutures and closely spaced radial ribs. It is yellowish-brown in colouration. The umbilicus is narrowly open in juveniles, closed by reflection in adults. The aperture is ovately lunate. It is identifiable by its large and distinctly ribbed shell.[3]
Distribution and habitat
editThe snail's distribution was limited to the vicinity of the summits of the southern mountains of the island, where it was found beneath stones and on wet rock faces.[3]
