Sigmurethra
Sigmurethra is a taxonomic category of air-breathing land snails and slugs, terrestrial pulmonate gastropod molluscs. This is an informal group which includes most land snails and slugs. The two strong synapomorphies of Sigmurethra are a long pedal gland placed beneath a membrane and retractile tentacles. Several families in this group contain species of snails and slugs that create love darts. Sigmurethra are known from the Cretaceous to the Recent periods. Taxonomy 2005 Taxonomy In the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005, Sigmurethra is an "Informal Group", a subsection of the Stylommatophora.Bouchet P. & Rocroi J.-P.

Elasmognatha
Elasmognatha is a taxonomic grouping, a clade, of air-breathing land snails and slugs, terrestrial pulmonate gastropod molluscs. A number of species in this taxonomic group are endangered. Taxonomy In the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005, Elasmognatha is treated as a clade within the larger clade Stylommatophora. The following two superfamilies and families have been recognized in the taxonomy of Bouchet & Rocroi (2005): *superfamily Succineoidea **family Succineidae *superfamily Athoracophoroidea **family Athoracophoridae Athoracophoridae, common name the leaf-veined slugs, are a family of air-breathing land slugs, terrestrial pulmonate gastropod mollusks in the infraorder Stylommatophora, the stalk-eyed snails and slugs.

Orthurethra
Orthurethra is a clade of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the clade Stylommatophora.

In the revised taxonomy of 2017 this taxon is no longer supported and has been replaced by the infraorder Pupilloidei.Bouchet P., Rocroi J.P., Hausdorf B., Kaim A., Kano Y., Nützel A., Parkhaev P., Schrödl M. & Strong E.E.
