Snout very short, obtusely pointed; lower eyelid scaly; ear- 

 opening round, slightly smaller than the eye-opening, without 

 auricular lobules. Nostril in the nasal; no supranasal; fronto- 

 nasal much more broad than long, in contact with the rostral and 

 with the frontal; latter as long as the frontoparietals, not larger 

 than the interparietal; four supraoculars; eight supraciliaries; 

 parietals forming a suture; four pair of nuchals; first upper 

 labial largest, fourth below the centre of the eye. Body long, 

 the distance between the tip of the snout and the fore limb 

 is contained one time and a half in the distance between 

 axilla and groin; 24 — 26 smooth scales round the middle, the 

 two vertebral series enlarged; praeanals enlarged. Tail thick. 

 Limbs short, widely separated when adpressed, hind limb as 

 long as the distance between the corner of the mouth and 

 the fore limb; digits very short, fourth toe longer than third, 

 with 10 smooth lamellae below.

 seven supraciliaries; frontoparietals frequently shorter than the 

 interparietal; parietals in contact behind the latter; four pair 

 of nuchals; fourth or fifth upper labial below the centre of 

 the eye. Body very long; the distance between the tip of the
