Potamopyrgus is a genus of minute freshwater snails with an operculum, aquatic gastropod molluscs or micromolluscs in the family Tateidae.[1]
Stimpson (1865) described the genus as follows: “Shell ovate-conic, imperforate; apex acute; whorls coronated with spines; outer whorl nearly two-thirds the length of the shell; aperture ovate, outer lip acute. Operculum corneous, subspiral. Foot rather short for the length of the shell, broadest in front and strongly auriculated. Tentacles very long, slender, and tapering. Eyes on very prominent tubercles. Rostrum of moderate size.”
