Lycodon gammiei

Gammie's wolf snake, or the Sikkim false wolf snake, is a non-venomous colubrid endemic to India, found in northern India in Arunachal Pradesh and Sikkim and in Darjeeling district of West Bengal. Its preferred habitat is forest. At first glance it resembles the venomous kraits: its body is encircled by alternating dark and light rings with irregular margins (Wikipedia, general species account).

The head is dark olive, with light spots in the centre of most head shields, an imperfect pale collar, and a whitish underside to the head and neck. Adults are about 80 cm in total length, including the tail, and it lays eggs.
