Head large, swollen below the ears, covered with unequal sized 
scales; snout obtuse, with obtuse canthus rostralis, with several 
large, more or less convex shields, the arrangement of which varies 
considerably ; they usually consist of three pairs which are either 
in contact or separated by small scales ; occipital slightly enlarged ; 
nostril large, oval, near the end of the snout, pierced in a convex 
nasal in contact with the large pentagonal rostral ; nine or ten upper 
and as many lower labials; a row of enlarged keeled infraorbitals, 
extending to the upper border of the tympanum ; latter large, verti- 
cally oval. Gular region covered with minute scales, on the sides 
intermixed with enlarged subconical tubercles; a row of large chin- 
shields, on each side, the anterior usually in contact with the labials, 
the others separated from them by smaller scutes. Dorso-nuchal 
crest rather low, but varying considerably, formed of triangular or 
lanceolate compressed spines, more or less distinctly lowered or in- 
terrupted between the shoulders and hind limbs; in a full-grown 
male, the longest spines (on the nape) measure two thirds the di- 
ameter of the tympanum. Scales of the body very small, more or 
less indistinctly keeled, scarcely larger on the belly than on the back. 
Limbs strong ; digits moderately long, the third toe strongly denti- 
culated along the inner side of the basal joint. Twenty to twenty- 
six femoral pores on each side, in a series extending along the whole 
length of the thigh. Tail long, compressed, crested above, with 
verticils of keeled scales forming regular segments on the sides, each 
segment composed of three to five series of smaller scales and a series 
of larger, slightly spinose ones. Green or dark olive above, speckled 
with darker and lighter, and with or without more or less distinct 
blackish transverse bands.
