Nessia burtonii, commonly known as Burton's nessia, Gray's snake skink, or the three-toed snake skink, is a species of skink, a lizard in the family Scincidae. The species is endemic to the island of Sri Lanka.
The specific name, burtonii, is in honor of British army surgeon Edward Burton (1790–1867).
N. burtoni has 24-26 scale rows at midbody. The body is slender and of equal girth from head to tail. The snout is acute. Each limb has three tiny clawed toes, hence one of the common names. The dorsum is brown or light reddish brown, each scale with a darker edge. The venter is creamy or may be gray.
A burrowing skink found in the wet zone of Sri Lanka, N. burtonii is widely distributed at 30–300 m (98–984 ft) at Gampola, Veyangoda, Lunawa, Mathugama, Kuruwita, Rakwana, and Kadugannawa.
N. burtoni is oviparous. Two eggs are laid in loose soil..
