[2] Gude's original text (the type description) reads as follows: Shell moderately umbilicated, lenticular, fulvous brown, rather thin, sub-translucent; the nepionic whorls shining, the remainder dull, finely closely ribbed, the ribs regularly curved and becoming more distant on the last quarter-whorl.

Whorls 5½, a little rounded above, flattened below, obtusely angulated above the periphery, increasing slowly and regularly, the last ascending a little in front.

Aperture crescent-shaped, oblique, margins distant, united by a very thin callus on the parietal wall, which is finely granulated.

Peristome curved, scarcely thickened, reflexed, livid; upper margin a little arcuate at the junction with the shell-wall, curved slightly forward, then suddenly receding, basal nearly straight, columellar receding a little at first, then curved forward, triangularly dilated longitudinally, and impinging upon the umbilicus, which is deep and cylindrical.
