Body elongated and slender, with well developed limbs. Tail consid- 

 erably longer than the rest of the animal. 



Head flat, tapering gently backward, more rapidly forward to the 

 rounded and projecting snout. Width of head in length to the groin 

 6 to 6.5 times. Eyes moderately large and prominent. Gular fold 

 prominent, on the sides of the neck projecting backwards. Tongue 

 boletoid and capable of protrusion. Vomero-palatine teeth in two short, 

 curved series, which approach but do not meet each other backward;- 

 neither do they reach to the parasphenoidal patches. Externally they 

 do not reach forward to the hinder borders of the choanre. The para- 

 spheuoidals in two distinct bands, approaching in front, but diverging 

 posteriorly. 



Body somewhat flattened, with a dorsal groove and thirteen costal fur- 

 rows. Distance from the snout to the axilla in the distance to the groin 

 2.6 times. The tail is low and flattened, about 1.5 times the length of 

 the remainder of the animal, sometimes nearly twice as long, running out 

 to a sharp point. 



Outstretched hind limbs contained in the length to the groin about 1.3^ 

 times ; toes and finjjers short.

 depth to an orange. Below, the tint is paler and without spots. Above

 specks to spots as large as the eye. The largest of these may form a row
