Shell description

Shell is dextral, rimate, ovate, thin, smoothish, somewhat glossy, pellucid, brownish-tawny. The shell has 5 to 5 ½ whorls, convex, the last nearly two-fifths the altitude, rounded at base, anteriorly having a somewhat swollen crest. [5]

Aperture is slightly oblique, semiovate or piriform, obstructed by 3 teeth: in the middle of the parietal wall, on the columella, and a smaller one in the palate (frequently wanting). Peristome is spreading, slightly labiate, the margins joined by a callus, the right margin very strongly curved above, columellar margin is somewhat dilated, spreading. [5]

The width of the adult shell is about 2.5 mm, the height about 1.5 mm. [5]
