Alinda stabilis
Alinda stabilis is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Clausiliidae, the door snails.[1] DescriptionThe length of the shell attains 14 mm, its diameter 3.5 mm. (Original description in Latin) The shell shows an arched slit, it is club-shaped and spindle-like. It is solid, tightly folded, translucent, and glossy with a horn-yellow hue. The spire tapers abruptly above, with a somewhat blunt tip. It comprises 11 convex whorls. The body whorl is swollen behind the aperture, rough in texture, and features a short crest at the base. The aperture is oval-pyriform, distinctly canaliculated at the base, with a thick palatal callus that narrows linearly. The upper lamella is relatively large, while the lower one is deep and subvertical, marked by a distinct crescent-shaped fold. The upper palatal fold is visible, and the columellar fold is slightly submerged. The peristome is continuous, free, and expanded, with sinuated upper and outer margins. [2] DistributionThis species occurs in Eastern Europe, mainly in Poland, Hungary and Romania. [3] References
