Zonitoides glomerulus is a European species of small, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Gastrodontidae.[1]
The diameter of the shell varies between 4.3 and 5 mm (0.17 and 0.20 in), its altitude is 2 mm (0.079 in).
(Original description in Latin) The shell has a narrow umbilicus. It is globular subdepressed. It is shiny, white and transparent. The shell contains four convex whorls. There are no spiral striae. The suture is deep. The body whorl is subequally convex above and below, slightly bent anteriorly. The aperture is slightly oblique, lunate-subcircular, with the edges removed to insert into each other. The wide columella is arched.[2]
