Rostral forming a trifle less than a right angle behind; nostril

 frontonasal a trifle longer than wide, in contact with the loreal; pre- 

 frontals broadly in contact ; frontal in contact with the first two supra- 

 oculars except for an abnormal granule lying on the suture; two pairs 

 of frontoparietals, posterior smaller, both except for the anterior part 

 of the first pair separated from the third and fourth supraocular by 

 one to three rows of granules; five occipitals in a transverse row, the 

 median one smaller and slightly anterior to the others; six supra- 

 ciliaries; four supraoculars the first separated from the loreal; three 

 posterior supraoculars separated from the supraciliaries by a single 

 row of granules; last supraocular, part of the next to last separated 

 from the outer occipitals by three or four rows of granules; seven 

 large supralabials; five large inf ralabials ; between infralabials and 

 chin-shields a wedge of a single row of granules extending anteriorly 

 to the middle of the second chin-shield ; chin and throat covered with 

 granules, an ill-defined band of larger ones extending across the throat

 the largest granules; on the area between the two throat folds four 

 or five irregular rows of scales, the median two rows widest; under side 

 of the body with twelve longitudinal and thirty-three transverse rows 

 of scales, the two outer scales on each side of the transverse rows much

 another smaller scale at each of the basal angles; on the lower arm, 

 two, or part three, rows of antebrachials, the outer widest; on the 

 upper arm a single (partly double) row of very large brachials con- 

 tinuous with the antebrachials; on the posterior side near the elbow 

 a group of small postbrachials; under side of thighs covered distally 

 with four, proximally with twelve rows of scales ; twenty-one femoral 

 pores; on the under side of the tibia three, part four rows of plates, 

 outer widest; upper side of the wrist covered with scales forming a
