Drummond-Hay's Rough-sided Snake

Drummond-Hay's rough-sided snake, known in Sinhala as ketiwal medilla, is a burrowing colubrid endemic to Sri Lanka, recorded in the Balangoda region and at Sinharaja. It is named for Henry Maurice Drummond-Hay (1869–1932), a planter and naturalist in Ceylon. The head is indistinct from the neck and the body cylindrical. The back is chocolate-brown with faint mottling and a dark stripe one scale wide from the snout to the tail tip, with two pairs of faint dark stripes on each side of the spine (Wikipedia, general species account).

It is known to lay four eggs at a time. Nationally Endangered (Sri Lanka National Red List 2012).
