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, on each side of it, 

 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 

 fines. 



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 with one 

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

 num 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
