context_page_description: Desmoulin's whorl snail is a species of minute air-breathing land snail, a terrestrial pulmonate gastropod mollusc or micromollusc in the family Vertiginidae, the whorl snails.
  This species was named in honor of the early-19th-century French naturalist Charles des Moulins.
context_section_description: The shell is dextral, minute, ovate, ventricose, obtuse at the apex, smoothish, subperforate. The aperture is semiovate, four-toothed, with one tooth on the parietal wall, another on the columella, and two palatals, the lower one longer. The shell has four whorls, parted by a distinct suture, the last doubly larger than all the others together. It is rather solid, glossy, subpellucid and of a uniform fulvous color.
  The shell of this species reaches about 3 mm in length. The shell is yellowish or brownish and translucent.
