Width 2.2 mm; 3 1/2 whorls; shell somewhat transparent; surface very finely and irregularly striate; first 1 1/2 whorls smooth; peristome with outer margin very slightly recurved, thickened within and visible through the shell as a bold white border.
Umbilicus elongate, widening rapidly in last 1/3 whorl;
Aperture oblique, forming 5/6 of a circle
Spire shallowly convex; whorls well rounded; body whorl not descending in front; peristome distinctly recurved at lower part only
Notes: Missouri, St. Louis Co., 1 mi N of Manchester, under boards and in soil in backyard [38° 36' 23"N, 90° 30' 22"W ]; abundant.
Differs from V. pulchella primarily by outer side of aperture very little or not at all recurved (best seen from above); the elongate body form or umbilicus mentioned by Pilsbry [LMNA, II(2):1026] does not seem to be consistently different between the species in this area.
