Partula atilis
Partula atilis was a species of air-breathing tropical land snail, a terrestrial pulmonate gastropod mollusk in the family Partulidae. This species was endemic to Raiātea, French Polynesia, but has not been seen since the 1980s and is believed to have become extinct around 1991–1992 due to predation by the introduced rosy wolf snail. It has been listed as extinct on the International Union for the Conservation of Nature's Red List since 1994.
