Section Emoa. Habit lacertiform ; the distance between the end of the snout and 

 the fore limb is contained once to once and one-fourth in the distance between axilla 

 and groin. Snout moderately elongate, obtusely acuminate. Lower eyelid with an 

 undivided transparent disk. Nostril pierced between three shields — a nasal, a postnasal, 

 and a supranasal ; frontonasal much broader than long, forming a broad suture with 

 the rostral and a narrower one with the frontal ; latter a little longer than tlie fronto- 

 parietal, in contact with the first and second supraoculars; four supraoculars; seven 

 or eight supraciliaries ; frontoparietals and interparietal fused to a single large shield ; 

 parietals forming a long suture behind the latter; a pair of nuchals and one or two 

 pairs of temporals border the parietals ; four or five labials anterior to the large 

 subocular. Piar-opening rounded, a little larger than the transparent palpebral disk, 

 with small projecting lobules in front and sometimes all round. 34 or 3G scales 

 round the middle of the body, dorsals and laterals with two to five (mostly three) 

 strong sharp keels ; dorsal scales largest, laterals smallest. Marginal prseanals not 

 enlarged. The hind limb reaches the axilla or the shoulder. Digits rather elongate, 

 cylindrical at the base, compressed at the end ; subdigital lamellae smooth, 34 to 38 

 under the fourth toe. Dark brown above, strongly iridescent, with numerous small 

 black spots; an ill-defined lighter dorso-lateral streak may be preseut; sides with
