Fowlea asperrimus — Boulenger’s Keelback
This species was formerly classified as Xenochrophis asperrimus.
This is a common semi-aquatic species, posing against its will on a rock. I found it sneaking through a marshy area on the grounds of my guide Udaya Chanaka's Runakanda Rainforest Conservation Center.
