Palaina levicostulata

Palaina levicostulata, also known as the fine-ribbed staircase snail, is a species of staircase snail that is endemic to Australia's Lord Howe Island in the Tasman Sea.

It is very pale to dark golden-brown in colour, sometimes with a white peripheral band on the final whorl.

The circular aperture has a strongly reflected lip and an operculum is present.

The animal has a white body with dark grey cephalic tentacles and black eyes.

[2] The snail is most common in the Settlement region, with a few records from elsewhere on the island.
