 irregular chocolate brown spots arranged in matched pairs down the 

 back, the first pair kidney-shaped and located behind the eyes across 

 the occipital region, followed by a large oval pair in the center of the 

 back and an irregular crescentic pair on the sacrum; about a dozen 

 medium-sized, oval, brown spots on the dorsolateral and lateral 

 regions, with a few small spots mixed with them; femur and forearm 

 similarly spotted above and posteriorly ; two very wide brown crossbars 

 on tibia and top of foot, and a brown spot on heel; upper lip with a 

 wide rectangular spot from eye to lip border, with a round spot follow-

Remarks. — The only two Brazilian examples of this species were

 features agree with those from the Argentine and Uruguay in the 

 U. S. national collection.
