the insertion of the fore-limbs. Beneath, the posterior half of the 

 abdomen and thighs are glandulous, whilst the anterior half appears

The ground color, as preserved in alcohol, is greenish-brown. One 

 large specimen reflects a rather reddish tint on the upper regions. 

 There is a dorsal lighter vitta, on each side of which there being extant 

 a series of large deep brownish-black spots, few in number. Another 

 series of similar, but smaller spots, is occasionally seen on the sides 

 beneath the glandulous ridges, and alternating with the dorsal series : 

 a few spots on the fore and hind legs, assuming upon the latter the 

 shape of transverse bars. A narrow black vitta extends from the tip 

 of the snout across the nostrils to the eye. The margin of both jaws 

 is maculated. An elongated spot is observed at the angle of the mouth.
