Xenelaphis ellipsifer

Xenelaphis ellipsifer, the ornate brown snake, or ocellated brown snake, is a large species of snake, up to 2.5 m long, which is found in Malaysia and Indonesia. It has a rounded snout, its head is distinct from its neck, and it has protruding large round eyes. The top of the snake (the dorsum) is orange-red in color, and along the sides of its body are large black-edged squarish brown blotches separated by cream colored spaces. It has a yellow upper lip. X.ellipsifer is an aquatic species, found in forests at 800 – above sea level.

The first description of this snake was published in 1900 by George Albert Boulenger, who found a single specimen in a fish trap above the Sarawak River in Malaysia. This snake became the type specimen of the species, and is held at the British Museum in London. Although this is a rare snake which has been described in few published reports, it is classified on the IUCN Red List as a species of least concern, since it is widely distributed in protected areas, and is therefore not under threat.
