extremities are rounded at the thigh, and greatly expanded at the tarsus; scaly 

 above, and scaly and granulate below; the toes are five in number, extensively 

 palmated, but fijrnished with only four nails. The tail is moderately long, 

 granulated and scaly, with a slight ridge of scales above. 



Colour. The head is dusky, marked with yellow lines; one begins at the tip of 

 the snout, and runs to the occiput; others from the same place, and on each side, 

 run over the orbit; others again, having the same point of departure, pass beneath 

 the orbit to a yellow spot which is there placed; several lines of similar colour 

 begin behind the orbit, and run down to the throat, while others pass over the 

 tympanum and along the side of the neck; a yellow spot, triangular and of large 

 size, is situated on the posterior part of the head; and at the cheek is another 

 remarkable spot of similar colour, included in a circle of black, which is in turn 

 surrounded by a yellow line. The jaws are horn-colour, marked with black and 

 yellow. The throat is marked with a great many yellow longitudinal lines, several 

 of which are bordered with black, or are included between two black lines. 



The vertebral and lateral plates are chestnut or cinereous-brown, marked with 

 lines of yellow or light brown; these run in all directions, and give a reticulated 

 appearance to the shell; the marginal plates are of similar colour, each Avith one 

 or more perpendicular yellow lines, and with their outer margin yellow; the 

 sternum is beautifully marbled with white and reddish-brown; the wings are 

 marked with oblong black blotches, surrounded by concentric dusky lines. 



The superior surface of the anterior extremities is black, with broad, yellow, 

 longitudinal lines, which run to the toes, and even tinge the webs and convex part 

 of the nails; the inferior surface is dusky, marked with irregular blotches and bars 

 of yellow. The posterior extremities are black above, with a few interrupted, 

 yellow, longitudinal lines, and with a remarkable band of similar colour along the 

 posterior border of the thigh and leg; the nates are brown, with yellow bands. 

 The tail is dusky above, with yellow longitudinal lines at the side, and yellow 

 'below.
