Palaina edwardi, also known as Edward's staircase snail, is a species of staircase snail that is endemic to Australia's Lord Howe Island in the Tasman Sea.
The globose pupiform shell of adult snails is 3–3.1 mm in height, with a diameter of 1.7 mm, with deeply impressed sutures. It is pale golden-brown in colour, with a white peripheral band on the final whorl and radial streak above the aperture. It has widely spaced axal ribs. The umbilicus is closed. The circular aperture has a strongly reflected lip and an operculum.[2]
The snail is rare and only found on the southern mountains of the island.[2]
