Nessia burtonii, commonly known as Burton's nessia,[1][2] Gray's snake skink,[3] or the three-toed snakeskink,[4] is a species of skink, a lizard in the family Scincidae.

[1][2] The specific name, burtonii, is in honor of British army surgeon Edward Burton (1790–1867).

It is sub-fossorial and occurs under leaf litter, boulders, and decaying logs in a variety of habitats: forests, plantations, and home gardens.

Each limb has three tiny clawed toes, hence one of the common names.

[citation needed] N. burtonii hides during the day, under rubble, decaying logs, and in leaf litter within submontane forests, up to 1,200 m (3,900 ft).
