separated by the small interparietal which is in contact with the frontal. Two 

 small suboval parietals on each side, and ten or twelve large scales surrounding 

 them behind. Loreal elongate ; labials 5-5. Four supraorbitals, the last two 

 separated from the frontal by granules. Six large infralabials, the last three 

 smaller and separated by two plates from the labials ; the anterior pair in contact. 

 Gular scales small, smooth, a wide band of smaller scales separating them from 

 those of the collar.

Tongue not furcate behind, but not received into a sheath as in Amiva. 

 Abdominal scales smooth in eight longitudinal rows ; preanal scuta in three rows 

 of two each, followed by two small round scuta in longitudinal line, surrounded 

 by small scales except in front. On each side of these a group of five spur-shaped 

 scales, with projecting acute apices, in two rows, of which the posterior includes 

 three. Gular fold bordered with small scales, which are preceded by two cross- 

 rows of large scutella. Gular region with a few median scutella of the same size 

 which graduate into those surrounding. 



Head rather elongate, frontal not divided ; frontoparietals distinct, longer 

 than wide. Three supraorbitals, the anterior partly isolated. Parietals and inter- 

 parietals each longer than wide, .surrounded on the sides and behind by one series
