Habit lacertiform : the distance between the end of the snout 

 and the fore limb is contained once and one fifth to once and one 

 third in the distance between axilla and groin. Snout rather 

 elongate, obtusely acuminate. Lower eyelid with an undivided 

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

 postnasal, and a supranasal ; frontonasal usually a little broader 

 than long, in contact with the rostral and usually also with the 

 frontal ; latter smaller than the frontoparietal, in contact with the 

 first and second supraoculars : four supraoculars ; seven or eight 

 supraciliaries ; frontoparietals united into a single large shield ; ' 

 interparietal distinct, small : parietals forming a short suture behind 

 the latter shield ; a pair of nuchals and a pair of large temporals 

 border the parietals : four or five labials anterior to the large 



Types examined.
