52 BATRACHIA. 



thighs posteriorly are bluish-purple, minutely dotted with white. 

 Underneath, the color is uniform yellowish-green. 



A young specimen exhibits a much deeper green hue upon the 

 upper region, while the sides of the legs are of a deeper yellow, almost 

 orange. In the same individual, the palatine teeth constitute but two 

 very indistinct groups, apparently more distant from each other, than 

 in the one just described ; but this may be accounted for by the 

 smaller size of the inner nostrils, which are elliptical instead of being 

 triangular. 



Specimens were found about fresh-water streams, near Woolongong, 

 Illawara, New South Wales, at the residence of the Attorney-General, 

 in January, 1840.
