36 Catalogue of Reptiles inhabit tin/ the 



Cot ours. The ground-colour of the head, neck, throat, gular pouch, 

 and the chest is impure gamboge, the scales edged with brown. The 

 eyelids dark brown, the tarsi buff. A. dark blue triangular streak 

 proceeds from the anterior angle of the orbit to the nostril ; another is 

 placed parallel with the upper labial scales, which as well as the lower 

 are of a pale blue, as also the tympanum. From the labial scales and 

 tympanum on each side across the throat, the pouch, and the sides of 

 the neck, proceed 7 oblique, undulating, dark blue bands. The tympa- 

 num is enclosed by two oblique broad, purple-brown bands, which join 

 each other under an angle at the anterior extremity of the cervical crest, 

 where a third broad, longitudinal purple-brown band commences, pro- 

 ceeding oyer the side of the neck, then expanding, covers the back and 

 the upper half of the sides of the body, where its lower margin describes 

 two large curves. The lower part of the sides are of a deep lilac, changing 

 on the abdomen to bluish white. On the sides of the body and on the 

 abdomen appear several oblique series of lozenge-shaped spots : a few 

 on the brown portion of the sides of a deep Indian red, the rest bright 

 gamboge. The cervical and dorsal crests are mulberry-brown ; the 

 former with the upper half of each of the first 13 scales light green ; 

 the latter with the upper half of the first 10 scales pale yellow. The 

 scales at the base of the crests partake of the general colour, but many 

 of them have a pale yellow spot. The tail is above and beneath with 

 alternate broad rings of impure white, the scales edged with brown, and 

 purple-brown, changing to black on the posterior half. The legs, feet and 

 toes are dark purple-brown with indistinct transversal yellowish bands.
