Rostral pentagonal, scarcely visible from above, separated from 

 the frontonasals by the anterior nasals, which form a short suture ; 

 a pair of frontonasals and a pair of prajfrontals, subequal in size ; 

 frontal heptagoual, the largest head-shield ; a series of four supra- 

 oculars ; a large heptagonal interparietal, not much smaller than, 

 and forming a broad suture with, the frontal ; a small frontoparietal 

 on each side, between the supraoculars, the frontal, the interparietal, 

 and a large temporal, which forms a suture with the interparietal 

 and the parietal ; latter one pair, smaller than the interparietal; 

 nostril pierced between two nasals and the first labial ; two loreals, 

 second largest ; temple covered with small flat squarish scales ; 

 seven upper labials ; mental trapezoid, followed by a heptagoual 

 postmental, and three large chin-shields on each side, the first pair 

 forming a suture ; lower labials not larger than upper. A strong 

 fold separates the head from the neck ; the gular scales anterior to 

 the fold, squarish, those between the latter and the collar roundish. 

 Nuchal and dorsal scales equal, granular, forming transverse series ; 

 ventrals large, square, forming eight longitudinal and twcnt5'-six 

 transverse series. Four squarish pra3anals, posterior pair largest. 

 Limbs weak ; digits short, inferiorly with a double series of tuber- 

 cular scales. Eight femoral pores on each side. Tail cylindrical, 

 tapering to a fine point, a little longer than head and body ; caudal 

 Bcales squarish, verticillate, largest inferiorly. Light brown above,
