AMERICAN FROGS OF THE GENUS RANA. 



467 



I have regarded this R. cesopus as specifically distinct from R. 

 areolata, under the name of R. capito. There can be no question that 

 Leconte's figure agrees with R. cesopvs as defined by Cope and not 

 with R. areolata ; however, Dr. Barbour has recently informed me that 

 Dr. Stejneger, having at his request reexamined the type of R. capito, 

 and compared it with the types of R. areolata and R. cesopus, states 

 it to be unquestionably the same as R. areolata and not R. aesopus. 

 I submit of course to Dr. Stejneger's verdict, but considering the state 

 of things resulting from it, it seems to me that a strict definition of the 

 species is an impossibility and I have therefore restored R. cesopus to 

 the rank of a subspecies or variety of R. areolata, assigned to it by its 

 original describer. 



The larva of R. areolata is still unknown.
