Xenochrophis cerasogaster

The painted keelback, sometimes called the dark-bellied marsh snake, is a colubrid snake found in Pakistan, Nepal, Bangladesh and India (Assam, Uttar Pradesh and West Bengal). Its total length is about two feet, with a tail of 5.5 inches. The Reptile Database also lists it in West Malaysia (Wikipedia and Reptile Database, general species account).

The scale description given for it is technical: the rostral is 1.5 to 3 times as broad as it is long, with one preocular, two or three postoculars and one or two suboculars. The sources opened give nothing on diet, habitat or breeding, so none is stated, and the entry is kept short.
