General Discussion 67 



Hyla cinerea may be the same as Hyla c. evittaia and close to Hyla 

 andersonii or possibly to Hyla gratiosa. 



Hylafemoralis is the Hyla versicolor representative of the piney woods. 



Hyla gratiosa may be apart but possibly may fall with Hyla cinerea 

 or Hyla andersonii. 



Hyla squirella. Does it fall with Hyla crucifer and .4cm gryllus, or 

 Hyla cinerea {cinerea, andersonii, gratiosa) group, or Hyla versicolor 

 ( H. arenicolor, femoralis) group? 



Hyla versicolor has as its nearest relative in Okefinokee, the piney 

 woods treefrog Hyla femoralis. 



Ratia aesopus is close to Rana areolata. These in turn are close to 

 R. sphenocephala and R. pipiens. 



Rana catesbeiana doubtless has its nearest relative in R. grylio or 

 R. clamitans. 



Rana clamitans is probably nearer Rana heckscheri than R. catesbeiana 

 or Rana grylio. 



Rana grylio is a bullfrog, doubtless belonging in the R. catesbeiana 

 group, yet it has affinities with R. clamitans or possibly R. virgatipes. 



Rana heckscheri doubtless comes closest to R. clamitans though more 

 must be known to place it carefully. 



Ra7ia septentrionalis is a puzzle. Is it close to R. virgatipes or near 

 R. clamitans, or a holoarctic form from Eurasian stock like some north- 

 western species? 



Rana sphenocephala is a southern Rana pipiens. 



Rana virgatipes may be a relative of R. grylio or close to R. septen- 

 trionalis. 



Gastrophryne carolinensis in tadpoles, eggs, etc. is different from G. 

 texensis. Possibly this or a Mexican species may be its nearest form.
