Ss) ? 5 Deas 
lines; of leg, 1 inch 8 lines; of tarsus and toes, 2 inches 2 lines. 
Hasits. Nothing peculiar is known of the habits of the Rana horiconensis. 
GrocrapuicaL Distrisution. The only place where this animal has been 
observed is at the outlet of Lake George, where I found it in 1834. 
GeneraL Remarks. There can be little doubt that this is a distinct species of 
frog. It differs from the Rana fontinalis in colour as well as in size; in the latter 
respect it approaches the Bull-frog, from which, on the other hand, it differs in 
being provided with two ridges, or cutaneous folds, along the back; nor can it be 
the Rana melanota of Rafinesque, as it wants the “yellow streak on the sides of 
the head.” Another reason for believing this to be an undescribed species of frog 
is its geographical distribution, which is just at that point where the waters run 
north to the St. Lawrence, instead of going south to the Hudson river, 
The name I have given it marks its habitat, Horicon being the ancient Indian 
name of that beautiful sheet of water now called Lake George.
