Colour in life: pinkish grey-brown with a blackish lateral stripe extending from the eye to the groin,uninterrupted above the shoulder; the dorsal margin of this strip is distinct, but ventrally it breaks up and becomes indistinguishable from the ventral pattern. There is a dark brown mid-dorsal marking that commences between the eyes (connecting the upper eyelids), narrowing behind the occiput, broadening between the shoulders, narrowing and broadening again, giving rise to two posteriorly-directed bands of variable length. In some specimens, the marking continues on narrowing and broadening again, and in others, it is interrupted between the broad patches. Among the other dorsal colour pattern variations observed were the absence of the retrorse markings and an indistinct pattern with the whole of the dorsum in a reddish-brown tint. There are a few indistinct, narrow, wavy bands parallel with the edges of the dorsal marking. Ventrally white with black (grey-brown in alcohol-preserved specimens) marbling. The pattern varies from one individual to another, but the marbling was observed in all specimens. Gular region blackish (grey-brown in alcohol-preserved specimens) with fine, white stippling. A black mark on the anterior side of the thigh, and an incomplete bar on its dorsal side. Vent enclosed in a black patch. Limbs with dark cross-bars (Fernando and Siriwardhane 1996).
