88 RANA FONTINALIS. 
The anterior extremities are pale green above, yellowish-white below, with 
irregular dark blotches on the posterior part of the arm and fore-arm; there are 
four fingers, moderately long and not palmate, yellowish before and dusky 
behind. ‘The posterior extremities are very long, dark green above, with dusky 
transverse bars or blotches; the inferior surface of the thigh is yellow, with its 
posterior half granulated; the nates are mottled yellow and black; the inferior 
surface of the leg is pale flesh colour, with a few minute black spots; there are 
five very long and well palmated toes, but not to their tips, which, as well as 
the webs, are lighter above and dusky below. 
Dimensions. Length from snout to vent, 33 inches; length of head, 10} lines; 
length of thigh, 1 inch 4 lines; length of leg, 1 inch 4 lines; length of tarsus and 
toes, 2 inches 5 lines: total length, from the snout to the tip of the toes, 8 inches 
7 lines. 
Hasirs. ‘The Rana fontinalis inhabits springs of cold water or the neighbour- 
hood of running streams; it passes much of its time on land, but leaps into the 
water when disturbed. Its food is small worms, or such insects as may come 
within its reach—these it never seizes unless they are in motion. 
GrocrapuicaL Distrisution. The Rana fontinalis is common from Maine to 
Virginia, but I am not aware of its existence in the more southern or in the 
western states. 
Generat Remarks. Leconte first pointed out the characters of this animal in 
his “Remarks on the genus Hyla and Rana.” Although he gave no description, 
still the characters he assigns are sufficient easily to distinguish it; therefore his 
name, which is a very good one, as giving the habits of the animal, must be 
continued. 
Harlan next calls this animal Rana flavaviridis—a name that cannot be 
retained, as Leconte’s has the right of priority.
