pe dusty brown; tip of rostral and lateral edges of
superciliaries dark cream-color; upper labials and sides of head
anterior to eyes cream-color, mottled with blue; lower labials and
postocular region pale blue; mental, postmental, and sublabials
cream-color. Upper surfaces of forelimbs dull bluish gray, spotted
with pale greenish yellow; dorsal surfaces of proximal one-fourth of
tail light brownish gray turning to pale orange-brown posteriorly;
lateral surfaces of tail bluish gray anteriorly and creamy brown
posteriorly. Nuchal region light bluish gray; flanks dark gray; dorsal
ground-color dark brown, somewhat paler posteriorly. Body having a row
of cream-colored spots in place of a lateral stripe, and another row
in place of dorsolateral stripe; dorsally, large diffuse tan or light
green spots partially fused and tending to form irregular transverse
markings. Chin to posterior end of sublabials pale pink, bordered
posteriorly by bluish white area, and then pink. Mesoptychials, under
surfaces of hind limbs, and belly cream-colored; anterior edges of
belly scales dark blue; lateral two rows of ventrals on posterior
two-thirds of body dark blue having light blue or cream-colored spots.
Under surfaces of forelimbs bluish cream; ventral surface of tail
cream-colored.

_Variation in Size and Scutellation._--The largest male has a
snout-vent length of 132 mm., the largest female, 114 mm., and the
smallest juvenile, 34 mm. The number of dorsal granules at the midbody
varies from 91 to 117 (106.2 +- 0.43); the ratio of the number of
granules between the paravertebral stripes to the number of granules
around the body (PV/GAB) varies from 0.064 to 0.157 (0.097 +-0.007);
the number of femoral pores varies from 32 to 49 (41.1 +- 0.20).
Usually there are only three enlarged preanals, but 18 specimens have
a somewhat enlarged scale anterior to the normal complement of three.
In 15 specimens the supraorbital semicircle-series terminate short of
the posterior edge of the frontal; in the others the series reach the
frontal.

_Variation in Coloration._--The coloration of juveniles and subadults
varies little; large adults vary considerably especially in the amount
of diffusion of the light green middorsal area. In some individuals
the vertebral pale area does not include the paravertebral spots; in
other individuals the pale area includes not only the paravertebral
rows, but, at least anteriorly, the dorsolateral rows. In large male
