nostril on left side but separated by a granular scale on right side of 

 head; nostril between the rostral, first supralabial (on left side) and 

 three scales behind and above, the upper one (supranasal) being 

 much the larger; 10 upper labials, the last becoming very small and 

 merging into the other granules, the suture between the eighth and 

 ninth falling below the center of the eye; 8 lower labials, the last ones 

 gradually becoming smaller; top of head covered with granules, which 

 are largest on the snout, especially on the canthus rostralis, with a few 

 coarser tubercles between the eyes; eye a little nearer to the ear than 

 to the end of the snout, its diameter about two-thirds the length of the 

 snout; ear opening vertical, oval, its maxinmm diameter greater than 

 the height of the largest supralabial; temples granular lil^e the top of 

 the head, with scattered, keeled tubercles; mental triangular, as wide

as rostral, its free border not twice as wide as nearest infralabial; 

 two chin shields on each side, the median pair much the larger, ir- 

 regularly hexagonal, then* inner anterior angle fitting into the corner 

 between mental and first infralabial, rather narrowly in contact with 

 each other on the median line and followed behind by small shields 

 alternating with other smaller granules shortly merging into those of 

 the tliroat; upper surface of body and flanks covered with granules a 

 little larger and rounder than those of the back of the head, inter- 

 spersed with large, convex, heavily keeled tubercles, each about as 

 long as three or four granules; these tubercles show a tendency to 

 form irregular longitudinal rows, there being about 16 across the middle 

 of the back; throat covered with small, flat, uniform granules strongly 

 contrasting with the imbricate cycloid scales of the rest of the under 

 side and of the legs; abdominal scales are a little larger than the 

 dorsal tubercles, about six contained in the distance from nostril to 

 eye; on the under side of the thighs the single outer series of scales is 

 larger, but without femoral pores in this (female) specimen; fingers 

 and toes free, all with long, compressed, angularly raised and clawed
