Habit laceriiform. The distance between the end of the snout 

 and the fore limb is contained once and one fourth or once and one 

 fifth in the distance between axilla and groin. Snout short, obtuse. 

 Lower ej-elid with an undivided transparent disk. Xostril pierced 

 in the nasal, which is quite lateral ; no supranasal ; frontonasal 

 broader than long, forming a very broad suture with the rostral and 

 a narrower one with the frontal ; the width of the suture between 

 rostral and frontonasal equals the width of the frontal ; latter shield 

 as long as frontoparietals and interparietal together, iu contact with 

 the first and second supraoculars ; four supraoculars, second largest ; 

 seven supraciliaries ; frontoparietals distinct, a little longer than 

 the interparietal ; parietals forming a suture behind the inter- 

 parietal ; a pair of nuchals and a pair of temporals border the 

 parietals ; fourth upper labial largest and entering the orbit. Ear- 

 opening oval, a little larger than the transparent palpebral disk. 

 26 smooth scales round the middle of the body ; dorsals largest. 

 Praeanals not or scarcely enlarged. The hind limb reaches the 

 wrist. Digits cylindrical ; subdigital lamelhe smooth, 24 under the

Habit lacertiform, rather stout; the distance between the end of 

 the snout and the fore limb is contained once and three fifths in the 

 distance between axilla and groin. Snout moderate, obtuse. Lower 

 eyelid with an undivided transparent disk. Nostril pierced in the 

 nasal ; no supranasal ; frontonasal broader than long, forming a 

 suture with the rostral, and in contact with the anterior angle of 

 the frontal ; latter shield shorter than frontoparietals and inter- 

 parietal together, in contact with the first supraocular ; three 

 supraoculars, first larger than the two others together ; seven or 

 eight supraciliaries : frontoparietals and interparietal distinct, 

 latter smallest ; parietals forming a short suture behind the inter- 

 parietal ; three pairs of nuchals ; fifth or sixth upper labial entering 

 the orbit. Ear-opening oval, smaller than the eye -opening, M'ithout
