It has a very light brown upper body with a narrow, dark brown line from the eye to the corner of the mouth. It is nocturnal and mostly arboreal, feeds exclusively on snails and slugs, and forages on agricultural land late at night. It prefers montane forest. Clutches are thought to be 5–7 eggs, likely incubating for about 6.5 weeks based on relatives. (Wikipedia, general species account)
