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. Highteen 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
