Differs from the preceding in the following points : — Frontonasal 

 much broader than long ; frontal hexagonal ; a small six-sided 

 occipital, separated from the interparietal, which is pentagonal, by 

 an elongate quadrangular shield ; four upper labials anterior to the 

 second infraorbital. Granules on sides of neck much enlarged. 

 Dorsal granules smaller, none enlarged. Limbs, and especially 

 digits, shorter ; the length of the tibia equals three fourths the 

 distance from end of snout to anterior lower border of ear-opening; 

 seven large plates under the tibia ; scales on upper surface of limbs 

 strongly keeled. Eighteen femoral pores. Caudal scales much 

 larger and keeled, the keels strongest on the sides. Upper surfaces 

 bluish (in spirits), guttate with lighter ; upper surface of head with 

 three longitudinal light bands, lost on the body ; gular region light 

 blue, marbled with blackish-blue ; belly dark blue ; tail yellowish
