|Diagnosis||Description: Head moderate, length about 5 times into length of head and body, from 1.33 to 1.5 times as long as broad; head shields smooth. Supranasals in short contact with one another, separating rostral and frontonasal, which is broader than long. Prefrontals usually in contact with one another, exceptionally separated by a shod suture between frontonasal and frontal. Frontal 6-sided, about 1.66 times as long as broad. Interparietal very small, 4-sided. Parietals in good contact behind interparietal. 4 Supraoculars, 1st and 4th smallest and subequal, 2nd largest, 2nd and 3rd in contact with frontal, from which 1st is usually separated by a short suture of prefrontal with 2nd supraocular, 4 Supraciliaries, 2nd longest. Anterior loreal smaller than posterior, in contact with frontonasal above and 1st upper labial below. 3 upper labials anterior to subocular, which is distinctly larger than adjacent labials and not or but little narrowed below. Temporal scales smooth, juxtaposed, about 8 in number. Tympanic shield large and semicircular, greatest breadth from a third to half of depth. Scales on nape smooth or but feebly keeled; on back, scales are strongly keeled but not striated, in 26 longitudinal and 51-54 transverse rows; lateral (i.e. 4 lowermost rows) quite smooth in adults and feebly keeled in juveniles. Ventral plates in 8 longitudinal and 32-34 transverse series, the outermost rows of shields are subequal in size to those adjoining on the inside. 14-16 Femoral pores on each side. Limbs somewhat short and stout. Scales on soles of feet flattened, oblique, keeled and imbricate; sub-digital lamellae smooth, 16-18 under 4th toe. Tail from 1.6 to almost twice length of head and body. Three enlarged preanal plates, the median subtriangular, with its apex just separating other two plates posteriorly (FitzSimons 1943: 275).|
Colour. Above, buff to sepia or olive brown, flecked and spotted on head and body with dark brown, each scale on back and tail also with a small yellowish elongate spot along its inner edge; on each side dorsolaterally, there are often 3-4 somewhat ill-defined, dark-edged, pale yellowish longitudinal stripes over back and tail, the uppermost commencing from last supraciliary and lowermost from behind ear-opening. Sides of body paler than back, spotted with dark brown and often with irregular pinkish suffusions. Limbs with large yellowish, dark-edged spots above. Lower surfaces uniform creamy white. In juveniles, upper surfaces darker, with a treble series of White-centred, dark spots down middle of back, those of median row being largest; a single dorsolateral, whitish, dark-edged stripe from back of head over back and tail; sides of body paler than above, with series of vertically elongate, yellowish-white spots (FitzSimons 1943: 276).
