Powelliphanta traversi, known as Travers' land snail, [1] is a species of large, carnivorous land snail, a terrestrial pulmonate gastropod mollusc in the family Rhytididae. This species is endemic to the North Island of New Zealand between Wellington and Lake Waikaremoana.

There are six subspecies, [2] all of which are listed by the New Zealand Department of Conservation as threatened: [3]

The eggs are oval and seldom constant in dimensions 10 × 8.75 mm, 9.5 × 8.5 mm, 10 × 8 mm, 11 × 9 mm, 10.75 × 9 mm. [4]

<i>Powelliphanta</i> Genus of gastropods

Powelliphanta is a genus of large, air-breathing land snails, pulmonate gastropods in the family Rhytididae, found only in New Zealand. They are carnivorous, eating invertebrates, mostly native earthworms. Often restricted to very small areas of moist forest, they are prey to introduced mammalian predators, and many species are threatened or endangered.

<i>Powelliphanta augusta</i> Species of gastropod

Powelliphanta augusta or the Mount Augustus snail, previously provisionally known as Powelliphanta "Augustus", is a species of large, carnivorous land snail, a terrestrial pulmonate gastropod mollusc in the family Rhytididae. Naturally occurring only on Mount Augustus near Westport on New Zealand's South Island, their entire habitat was destroyed by coal mining. The world population was taken into captivity, in theory until their habitat was restored and they could be released. The mining company concerned went bankrupt and habitat restoration has been unsuccessful, so the species' future is uncertain.
