Head moderate ; snout rather obtuse ; upper head-shields strongly 

 striated ; nasals feebly swollen ; frontonasal broader than long, 

 separated from the rostral ; two pryefrontals ; frontal scarcely 

 grooved ; two large supraoculars, completely surrounded with gran- 

 ules ; two scales on a line from the loreal to the anterior supraocular, 

 the length of which equals its distance from the loreal ; interparietal 

 rhoniboidal, as long as or a little shorter than the suture between 

 the frontoparietals ; occipital absent or minute ; parietals as long as 

 broad, with an elongated shield on their outer border; temporal scales 

 small, strongly keeled ; a curved band-like scale on the supero- 

 anterior border of the ear ; no auricular denticulation ; lower eyelid 

 scaly ; subocular bordering the lip, between the fourth and fifth (or 

 fifth and sixth) upper labials ; the three anterior pairs of chin-shields 

 in contact. Collar curved, perfectly free, with nine plates. Dorsal 

 scales rhomboidal, juxtaposed, strongly keeled, 64 or 06 across the 

 middle of the body. Ventral plates in straight longitudinal and 

 transverse series, all much broader than long ; in six longitudinal 

 series, the median pair narrower than the two others ; 27 or 28 

 transverse series. Praeanal scales small, irregiilar. The bind limb 

 reaches the ear or the eye ; foot as long as the distance between the 

 arm and the nostril or the end of the snout ; a single series of 

 large subtibial plates. 14 to 18 femoral pores on each side. Tail 

 more than twice as long as head and body ; caudal scales strongly 

 keeled, except the basal subcaudals, which are obtusely keeled.

 indistinct one along each flank ; small black cross bars between the
