Vertigo - The shell is deeply rimate and ovate. The apex is acuminate and obtuse. The shell has 5-6 whorls. The last whorl is rounded. The aperture is semioval with 4 to 7 folds. The peristome is scarcely expanded and white-lipped. (Baker 1902)

Meaning behind Latin word:
Animalia - The word "animal" comes from the Latin word animalis, meaning "having breath". (Creswell 2010)
Mollusca - The words mollusc and mollusk are both derived from the French mollusque, which originated from the Latin molluscus, from mollis, soft. (Little 1964)
Gastropoda - The word gastropod comes from the Ancient Greek words γαστήρ (gastr-) "stomach", and πούς (pod-) "foot", hence stomach-foot. This name is based on the fact that snails and slugs appear to crawl on their stomachs. (Cuvier 1795)
