The 1.4-2.1 x 3-4 mm. shell is variable. It has 4-5 whorls and the last whorl width seen from above 1.5-2 x of penultimate whorl. The umbilicus is narrow, much narrower than in Vitrea botterii, but clearly open, showing penultimate whorl, initially narrower, widened only at last whorl. Usually smaller than V. diaphana, and larger than V. contracta which has more densely coiled whorls.[2]
