Zonitoides hoffmanni is a European species of small, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Gastrodontidae. ^[1]

Description

The diameter of the shell varies between 5.3 and 6 mm (0.21 and 0.24 in), its altitude is 2.5 mm (0.098 in).

(Original description in Latin) The shell has a broad umbilicus. It is conoid-depressed and is striated. It is smooth with a pale greenish color. The shell contains 4½ convex whorls. The suture is deep enough. The body whorl is rounded, not bent anteriorly, excavated below, gradually reaching almost to the umbilicus. The aperture is slightly oblique, emarginate-subcircular, with removed edges. The columella is distinctly ascending. ^[2]
