The adults range from brown to brick-red colour on the upper surface. Ventral scales are white to pale yellowish in colour. Thick black stripes on either side of the posterior body and tail is a characteristic feature. Juveniles often greenish in coloration. The pupil is rounded and large.<ref>{{Cite web|url=http://www.ecologyasia.com/verts/snakes/white-bellied_rat_snake.htm|title = White-bellied Rat Snake - Ptyas fusca}}</ref> ==References== {{Reflist}}
