RANA FONTINALIS. 89 



It is possible that this animal may prove to be the Rana viriscens of Kalm, 

 quoted by Gmelin and other naturalists, although it cannot now be positively 

 affirmed, as I have hitherto been unable to find any animal described by Kalm, 

 bearing this name, either in his "Travels" or in those works where many of his 

 observations were published, as the Swedish Transactions, &c.; so the specific 

 name given this animal by Leconte must, for the present, be used. 



Dumeril and Bibron consider this animal as identical with the Rana clamitans, 

 from which, however, it differs in having the head shorter and less pointed; the 

 tympanum is smaller, the body is shorter and rounder, and the colour, as well 

 as geographical distribution, are very different.
