DiagnosisDescription: Snout somewhat attenuate and rather pointed. Head slightly depressed, about 4 times into length head and body in males (a little more in females), about 11 times as .long a broad, as broad as or broader than neck. Loreal region vertical; canthus. rostra:lis rounded. Limbs moderate, adpressed hindlimb reaches elbow or a.little beyond in males, just overlapping forelimb in
.females. Foot as long as or a little longer than, head. Nasals in contact with one another behind rostral. Frontonasal broader than long, more or less 4-sided (with anterior horder almost semicircular) or subpentagonal. Prefrontals in good contact with one another. Frontal hexagonal, a little shorter than its distance from tip of snout, from lJ} to almost twice as long as broad a little loncrer than frontoparietals + interparietal, as, broad as or ~ little broader than supraoculars. Parietals about l§ -times as long as broad. Interparietal elongate, pentagonal much longer than broad (about 2! times), broader in front than behind, in contact with occipital which is as
broad as or a little broader than interparietal, and projects slightly beyond panetals. Two upper temporals on each side anterior over twice length of posterior and in contact with last sup~aocular. Four supraoculars, 1st very small and elongate, 2nd much the largest and in contact with prefrontal, 4th larger than first. Four supraciliaries, 1st largest but as long as or shorter than 2nd. Nostril pierced in the nasal and bordered behind by two small superposed postnasal" (exceptionally only one present owing to upper one fusing with nasal); 1st'upper labial usually entering nostril (exceptionally narrowly separated therefrom); rostral usually narrowly separated from nostril (exceptionally just entering); lower postnasal resting ,on 1st upper labial only, exceptionally just overlapping 2nd. Anterior ioreal distinctly smaller and shorter than posterior. Four upper labials anterior to subocular, which is moderately narrowed below7 and there much longer than adjacent upper labials; a distinct keel from freno-ocular and along upper border of subocular. Temporal scales smooth, one or two immediately preceding the large obliquely elongate tympanic shield (in the same line)" vertically elongate and distinctly larger than remainder. 6 Lower labials; 5 enlarged chin-shields on each side, the three anterior pairs being in median contact with one another. Gular scales moderate and imbricate; a well- marked gular fold across·,throat. 3-4 Rows of scales on nape very small,_smooth and granular:, passing gradually into the large strongly keeled and moderately mucronate scales on back; dorsais in 38--44 transverse series between occiput and base of tail; scales less strongly keeled towards sides, but lowermost row only sometimes smooth; 23-29 scales across middle of body. Scales on side of neck (from ear-opening to -axil) small, smooth "and more or less granular. Ventral plates in 6 longitudinal rows and 22-26 (usually 22-25) transverse series, those in t,he 2nd .row from middle line largest and much broader than long. Two enlarged preanal plates, one in front or the other, the posterior being larger than the ainterior. 7-12 (usually 9-12) femoral pores on each side. Scales on upper surface forearm smooth or feebly keeled, on tibia rhombic, keeled and imbricate. Subdigital lamellae smooth, and for the most part, paired on longer digits, 19-23 (usually 22) lamellae under 4th toe. Scales on tail keeled and shortly mucronate, except at base below, where they are smooth and much broader (from Fitzsimons 1943: 304).
