Skin smooth above; a feeble fold above the tympanum, and usually another across the chest; belly and lower surfaces of thighs granular.
Upper surface dark purplish brown, with white (in life yellow) spots and streaks, or lighter brown, with the spots and streaks pale brown or dirty white; there are three broad longitudinal streaks on the back, one median, beginning between the eyes or at the tip of the snout, and two lateral ones, beginning on the canthus rostralis or the upper eyelid; small spots on the head and sometimes on the sides; a more or less discontinuous streak at each side of the median one may be present; sometimes a cross-bar on the rump, or another between the eyes; upper surface of limbs pale brown with light dots; yellowish white beneath.
