Head large, swoUen 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 x^airs 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 largo, verti- 

 cally oval. Gular region covered with minute scales, on the sides 

 intermixed with enlarged subcorneal 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 twentj'- 

 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.
