Description. — " Habit slender, body elongate. The distance 

 between the end of the snout and the fore-limb is contained once 

 and two-thirds to twice in the distance between axilla and groin. 

 Snout short, obtuse. Lower eyelid with an undivided trans- 

 parent disk. Nostril 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 ; latter shield as long as or a little shorter than the 

 frontoparietals and interparietal together, in contact with the 

 two anterior supraoculars ; four supraoculars, second largest ; six 

 or seven supraciliaries ; frontoparietals normally distinct (united 

 in some specimens), as long as or a little longer than the inter- 

 parietal ; parietals forming a suture behind the interparietal, 

 bordered by a pair of nuchals and a pair of temporals ; fourth 

 upper labial largest and entering the orbit. Ear-opening oval, 

 not larger than the transparent palpebral disk. Twenty-two to 

 twenty-four smooth scales round the middle of the body ; dorsals 

 largest. Prseanals not or but feebly enlarged. The adpressed 

 limbs fail to meet. Digits cylindrical ; subdigital lamella? smooth.
