Rostral forming a trifle less than a right angle behind; nostril 
between the two nasals; anterior pair of nasals broadly in contact; 
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 infralabials; 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 
of which a broad group in the median posterior region is composed of | 
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 
the smallest; preanal plates in a triangle of three large scales with 
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 
regular series of longitudinal rows; inner and outer toe extending 
approximately the same; tail covered with straight, keeled scales; 
about forty-one scales in the fifteenth ring from the base.
