Cope's Rough-sided Snake

Cope's rough-sided snake, known in Sinhala as kalu medilla, is a burrowing colubrid endemic to the mountains of central Sri Lanka, with recorded localities that include Dimbulla, Dickoya, Balangoda and Pundaluoya. It is named for the herpetologist Edward Drinker Cope. The head is indistinct from the neck and the body cylindrical. The back is brown with a brownish-olive band along the spine flanked by 23 to 26 dark blotches on each side, and the belly is mottled green (Wikipedia, general species account).

Adults may reach 63.5 cm in total length. Little is known of its reproduction: only one female has been found, with 21 'remarkably round' eggs. Nationally Data Deficient (Sri Lanka National Red List 2012).
