Amphiesma pealii, commonly known as the Assam keelback, is a species of natricine snake endemic to India.
Etymology
The specific name, pealii, is in honor of "Mr. S.E. Peal", who collected the two specimens from which British zoologist William Lutley Sclater described this snake as a species new to science.
Geographic range
It is found in the Indian state of Assam.
Description
Amphiesma pealii may attain a total length of 50 cm (19⅝ inches), which includes a tail 12.5 cm (4⅞ inches) long.
Dorsally it is dark brown. On each side are two light stripes, an upper narrow one, and a broader lower one, which is two scales wide. The top of the head is dark brown. The rostral, the upper labials, and the lower labials are yellow, blotched and edged with brown. The ventrals are very dark brown, marked with light yellow laterally. There is also a faint yellow stripe along the center of the ventrals, which becomes more distinct posteriorly.
The dorsal scales are strongly keeled (less strongly in the outermost row), and arranged in 19 rows at midbody. Ventrals 142-144; anal plate entire; subcaudals 75-77, divided.[2]
