Voiuero-palatiue teeth in four distinct series, made so by interruptions^ 

 in the middle line and immediately inside the choanse. The latter open- 

 ings more widely separated than the outer. The body is short and de- 

 pressed. The distance from the snout to the axilla is just equal to that 

 from the axilla to the groin. There are eleven distinct costal furrows 

 and a dorsal groove. The tail is ecjual to the distance from the snout to 

 the beginning of the vent. It has a well developed crest and is com- 

 pressed. Hind foot with two distinct tubercles. 



The limbs are well developed, the posterior being a little longer, some- 

 what stouter, and the foot broader than the same parts in a specimen of 

 A. tigrinmn of the same size. 



The color above is dark brown, almost black ; below, brownish yellow. 

 Between the fore and the hind legs the yellow color mounts up on the 

 sides of the body to a level with the upper surfaces of the limbs. Head 

 above like the back, below like the belly, with indications of a brighter 

 yellow gpot behind the symphysis. 



This description is founded on the only known specimen, which wa& 

 captured at Irvington, near Indianapolis. Nothing whatever is known 

 coucerninir its habits.

 4 times. Gular fold not prominent, but rising high on the neck. Another 

 fold from the angle of jaw running back to gular fold. Eyes of mod- 

 erate size. Mouth large. Tongue moderate, with the papillary folds 

 radiating from behind. Teeth of vumero-palatines in three portions, the 

 extremities of the series being separated from the median portion by in- 

 terruptions just behind the choanal. The latter openings considerably 

 further apart than the external nostrils. 



Body plump, with a dorsal groove and 11 (occasionally 10) costal fur- 

 rows. The distance from the snout to the axilla in distance from snout
