tion reaches the anterior angle of the orbit. Skin smooth, only on the pos- 
terior part of the belly and on the lower and hinder surface of the thighs 
granutaled ; a very fine line runing along the middle of the back. 
With regard to the structure of the mouth, the large, entire tongue 
(plat X. fig. 4), the absence of vomerine teeth, a cutaneous, distinetly den- 
ticulated ridge across the palate in front of the pharynx, befor them still 
three small dermal proeminences to appears (pl. X. fig. 5), deserve notice. 
Coloration. Yellowish red above, powdered with blakisech dots, which 
are denser on back and sides of the body, forming indistinct spots; these 
points are namely on the forehead so crowded, that the upper surface and 
sides of the snout and the upper eyelids appear nearly black; the inter- 
space between the upper eyelids also black and sharply separeted in front 
from the black of the snout; shoulderregion dark; limbs with traces of 
dark eross-bars ; hands and feet together with the fingers and toes irregu- 
larly darkened, the diks on the fore edge yellow, dark behind and separeted 
by a light ring from the dark posterior phalanges. Beneath light reddish 
brown, powdered with dark brown. Iris nearly blackish brown, with traces 
of a coppery vellow puncture. 
The young specimen has the same coloration, but differs from the 
adult in this, that on the upper part of the snout, the anterior half and 
outer edge of the upper eyelids are dirty white instead of black and sharply 
separed from the straight fore edge of the dark bloteh between the upper 
eyelids.

toes a little smaller than the diameter of the tympanum ; skin guite smooth 
above, rough and granulate on breast, belly and lower and hinder surface 
of thighs. 
(oloration. Green above ; a sharp white streak runs along the lower 
jaw, prolonged below and behind the tympanum, dark-edged on the upper

This species was up to this time only known from North Australia.
