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.
