to define the range of either one. Leopard frogs are found all over the 

 State but it is possible in only a few instances to determine to which form 

 the published records refer. I have collected specimens at Refugio and 

 Burnet that I can refer with certainty to sphenocephala, but these col- 

 lected at Waco all seem to be typical pipiens. If the two forms are dis- 

 tinct species, they probably occur together through the greater part of 

 their Texas range. 



Specimens collected in the mountains of Jeff Davis and Brewster coun- 

 ties are too young for satisfactory determination, but adult leopard frogs 

 from El Paso are near to Rana pipiens austricola Cope, if not that sub- 

 species.
