The type locality is Devonshire, England.[5]
Description
The shell is very small.[4] The shell has 1.5 whorls.[4] The last whorl is inflated.[4] The aperture is oval and very large, like in succineids, columellar and parietal sides of the margin thickened.[4]
The width of the shell is 2-5 mm.[4] The height of the shell is 1.5-3 mm.[4]
Animal cannot withdraw entirely into the shell.[4] Eyes look like in comic snails.[4] Otina ovata has no tentacles.[4]
Habitat
