pulmonata's Usage Examples:

In some Pulmonata (snails) the foot is extended at right angles to the visceral hump, which rises from it in the form of a coil as in Streptoneura; in others the visceral hump is not elevated, but is extended with the foot, and the shell is small or absent (slugs).

The Pulmonata are, like the other Euthyneura, hermaphrodite, with elaborately developed copulatory organs and accessory glands.

An operculum is present only in Amphibola; a contrast being thus afforded with the operculate pulmonate Streptoneura (Cyclostoma, 'c.), which differ in other essential features of structure from the Pulmonata.

- PuLMONATA.

The Euthyneura comprises two orders, Opisthobranchia and Pulmonata.

The genital duct is now said to be diaulic, as in Valvata, Oncidiopsis, Actaeon, and Lobiger among the Bullomorpha, in the Pleurobranchidae, in the Nudibranchia, except the Doridomorpha and most of the Elysiomorpha, and in the Pulmonata.

in Actaeon and Limacina among Opisthobranchia, and Chilina among Pulmonata.

Pulmonata.

This conclusion has shown that the Euthyneura do not represent an archaic form of Gastropoda, but are themselves derived from streptoneurous forms. The difference between the two sub-classes has been shown to be slight; certain of the more archaic Tectibranchia (Actaeon) and Pulmonata (Chilina) still have the visceral commissure long and not untwisted.

In aquatic Pulmonata the osphradium is retained.

pulmonata's Meaning':

large order of gastropods usually breathing by means of a lung-like sac comprising most land snails and slugs and many freshwater snails
