Description
For terms see gastropod shell.
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.[1]
Distribution

- Czech Republic
- Ukraine[2]

gollark: `The Frog Cannot Be Obtained` - I should name a dragon that.
gollark: I asked explicitly for shadow walker hatchlings on the hub. What do I get? Not shadow walker hatchlings.
gollark: You can do hatchling ND experiments if you're crazy, I think.
gollark: Dropped in time, I mean.
gollark: But when the hatchlings drop won't the other eggs also have dropped?
