This is a small species, about the size of the 

 Principalis, and is entirely smooth or destitute of 

 any dorsal carina or serratures, but is furnished 

 with a large, flattish gular pouch or crest of 

 a pale red colour, while the rest of the animal is of 

 a pale blueish grey, v/ith a few slight variega- 

 tions of a more dusky tinge : the tail is much 

 longer than the body, and is of similar colour, 

 with a few obscure transverse bands : the limbs are 

 moderately slender, and the whole habit is in some 

 degree similar to that of the Principalis. It is a 

 native, according to Seba, of South America.
