It is smooth, glossy and dark amber-brown in colour in live animals, the empty shell being golden-brown. The whorls are rounded, with flat sutures and finely incised spiral grooves. It has an ovately lunate aperture and closed umbilicus. The animal is dark grey with darker eyestalks. Distribution and habitat
The snail has a patchy distribution across the island and is found in leaf litter and the axils of palms. References
