Thwaites' Skink

Thwaites' skink, or the fourtoe snakeskink, is the only species in its genus and is endemic to Sri Lanka. It is highly fossorial and known from the Knuckles Mountain Range at 700 to 1,000 m. It is named for the botanist George Henry Kendrick Thwaites. The eyes are small with scaly lower eyelids, the body and tail elongate with the tail as wide as the body, and the limbs short and rudimentary with four toes each. The back is dark brown with a blackish-brown central region (Wikipedia, general species account).

In many places it lives alongside Nessia and Lankascincus skinks. It eats insects, and in April an adult female may lay a clutch of two eggs. No national Red List category was found.
