Pila virescens is a species of freshwater snail in the family Ampullariidae, the apple snails. ^[2]

Description

The shell can grow quite large, up to 95 mm, its diameter 68 mm.

(Original description in Latin of Ampullaria pagoda ) The shell is perforated, ovate-globose, and unequally rugose. It is olive-colored, longitudinally marked with a few brownish or reddish streaks, and appears purplish-violet internally. The spire is exserted, conical, and acute at the apex, displaying a purplish-blackish hue. It comprises nearly six convex whorls, with the body whorl being ventricose and then attenuated. The aperture is ovate-oblong, mediocre, and somewhat effuse at the base. The peristome is internally thickened, and the columellar margin is dilated, briefly projecting, and rubricated. The external margin is black-limbed. The operculum is testaceous and thick. ^[3]

Distribution

No type locality is given (Manila, the Philippines ?). Ampullaria pagoda has been reported in Cambodia.
