(Pease, 1865)

Partula turgida, also known as the Raiatean thin-shelled partula, is an extinct species of air-breathing tropical land snail, a terrestrial pulmonate gastropod mollusk in the family Partulidae. This species was endemic to Ra'iātea, French Polynesia. It is now extinct.

Partula clarkei, misidentified as this species, was being kept alive in captivity, when the population suffered a crash caused by the microsporidian genus Steinhausia. This is the first definitive report of an extinction of a species caused by a parasite.

The genus Partula was presumed to have been established around 1.5 million BC.
