See text Polygyridae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea.

[3] This snail family is distinguished from other gastropods on the basis of several anatomical features: They have no dart apparatus (see love dart), the muscles which allow the eyes and pharynx to be retracted are united into a single band, and the jaws are ribbed.

[4] In this family, the number of haploid chromosomes lies between 26 and 35 (according to the values in this table).

[9] Pilsbry[3] uses the generic names Allogona, Ashmunella, Giffordius, Mesodon, Polygyra, Praticolella, Stenotrema, Trilobopsis, Triodopsis, and Vespericola.

The remaining names listed here have either been elevated from Pilsbry's subgenera since 1940, or newly created.
