Pleurocera

Pleurocera is a genus of freshwater snails with an operculum, aquatic gastropod molluscs in the family Pleuroceridae.

[3] All of the species in this genus have thick-walled high-spired shells, and some attain a length of over 4 cm (1.6 in).

[3] Opercula are paucispiral and corneous, but may be vestigial in some species, not completely closing the aperture.

The soft parts of the animal usually have a gray or brown coloration, commonly speckled with orange.

Pleurocera gonula Rafinesque, 1831 (nomen dubium) Most species inhabit larger rivers.
