The 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](/wiki/Suture_%28anatomy%29 "Suture (anatomy)") and closely spaced radial ribs. It is yellowish\-brown in colouration. The [umbilicus](/wiki/Umbilicus_%28mollusc%29 "Umbilicus (mollusc)") is narrowly open in juveniles, closed by reflection in adults. The [aperture](/wiki/Aperture_%28mollusc%29 "Aperture (mollusc)") is ovately lunate. It is identifiable by its large and distinctly ribbed shell.
