Description
editThe ear-shaped shell of mature snails is 5.5–7 mm in height, with a diameter of 8.8–9.6 mm, with a moderately low spire, impressed sutures and whorls rounded with a supraperipheral sulcus. It has orange-brown and cream flammulations (flame-like markings). The umbilicus is very narrow, covered by the reflected lip. The ovately lunate aperture is distorted by a groove.[3]
Habitat
editThe snail is only known from the summit of Mount Lidgbird, where it was found crawling on wet rock faces. It has not been seen since 1914, when it was collected in large numbers, and it may be extinct.[3]
