longer than frontoparietals and interparietal together, in contact 

 with three supraoculars; four supraoculars; seven supraciliaries 

 anterior to the fourth supraocular, first and second large, the 

 others small; frontoparietals shorter than interparietal; parietals 

 forming a suture behind the latter. Six upper labials, fourth 

 largest, with a groove from the lower posterior corner to the 

 upper anterior one, bordering the orbit; five lower labials; a 

 postmental, followed by three pair of shields, the first and 

 second in contact, third separated by four scales. Tympanum 

 oval, larger than the eye-opening. Body slender, with 34 scales 

 round the middle, dorsals strongly keeled, with a sharply 

 pointed hind border, the keels forming six longitudinal lines; 

 lateral scales smaller, keeled, forming oblique series. Ventral 

 scales as large as dorsals, smooth, in 6 series; scales of the 

 chin smooth, those on the throat keeled, the two middle 

 rows excepted. Praeanal region with one large plate. Tail with 

 keeled scales, the middle lower series of broad shields smooth. 

 Limbs slender, the hind limb reaches the fingers; digits with
