 Hind limb reaching between the collar and the ear; foot a little longer 

 than the head ; toes slender, rather strongly compressed. Tail about 

 twice as long as head and body, flattened at the base, slightly 

 compressed posteriorly. 



Upper head- shields flat, smooth ; nasals in contact behind the 

 rostral, tlie suture between them f or i- the length of the frontonasal, 

 which is broader than long ; prefrontals a little broader than long, 

 forming a median suture*; frontal shorter than its distance from the 

 end of the snout. If to If times as long as broad, narrow behind, 

 separated from the supraoculars by a series of granular scales ; 

 parietals a little longer than broad ; interparietal much smaller than 

 the frontoparietals, sometimes very narrow; no occipital. Two large 

 supraoculars, followed by a band-like third, the first as long as the 

 second and longerf than its distance from the second loreal, the space 

 in front of it filled by small shields or granules ; 5 to 7 superciliaries, 

 fiz-st longest ; a series of granules between the supraoculars and the 

 superciliaries. Eostral as deep as broad, narrower beneath than 

 above ; 3 nasals, the lower in contact with the 3 first upper labials 

 and separated from the rostral ; anterior loreal as long as deep or a 

 little longer than deep, shorter than the second ; subocular keeled 

 below the eye and largely bordering the mouth, between the sixth and 

 seventh or fifth and sixth upper labials. Temporal scales granular,

5 pairs of chin-shields, the 3 anterior in contact in the middle ;

 chin-shields and the median collar-plate ; gular fold distinct. Collar 

 curved, free, composed of 9 to 14 small plates. 



Scales granular, smooth, 55 to 68§ across the middle of the body. 

 Ventral plates in 18 or 20 oblique longitudinal and 36 to 38 1| trans- 

 verse series, the plates mostly longer than broad. Preanal region
