Head small ; snout short, obtuse. Ear-opening much larger than 

 the nostril. Frontonasal broader than long, widely separating the 

 nasals ; praefrontals present, widely separated ; frontal shorter than 

 frontoparietals and interparietal together ; 5 supraoculars, 3 an- 

 terior in contact with the frontal; 10 supraciliaries ; parietals 

 forming a suture behind the interparietal ; no nuchals ; third, 

 fourth, and fifth upper labials below the eye, from which they are 

 separated by a series of small scales. 26 scales round the middle 

 of the body, laterals a little smaller than dorsals and ventrals, dorsals 

 and laterals feebly bi- or tricarinate. Prseanal scales not or scarcely 

 enlarged. Limbs short, widely separated when adpressed ; third
