Sigmurethra

Stylommatophora is an infraorder (also sometimes considered an order) of air-breathing land snails and slugs, terrestrial pulmonate gastropod molluscs. This infraorder includes the majority of land snails and slugs.

The two strong synapomorphies of Stylommatophora are a long pedal gland placed beneath a membrane and retractile tentacles (Borda V. et al, 2008).

A few families in this group contain species of snails and slugs that create love darts.

Stylommatophora are known from the Creataceous to the recent periods. [(in Czech) Pek I., Vašíček Z., Roček Z., Hajn. V. & Mikuláš R.: "Základy zoopaleontologie". - Olomouc, 1996. 264 pp., ISBN 80-7067-599-3.]
