along almost any of our streams. At times of high water these 
big frogs leave the inundated regions and migrate to higher 
ground. ‘They are caught for the market in great numbers, and 
were it not for their great fertility, they would soon become ex- 
tinct, as indeed is the case in some parts of the country. Frog 
farms exist to supply the market and when well conducted are 
ready sources of revenue. Common over the State. 
Specimens in the U. S. Nat. Mus., recorded by Cope from Marietta and 
Elyria. In the O. S. U. Mus., collected by R. C. Osburn at Columbus, and 
by E. V. Wilcox at Central College and Lake Erie. 
Rana sylvatica Le Conte. Sides of head with a chocolate band run- 
ning from snout backward. Below this a light line. Brownish spot on base 
of arm. Above brown, below lighter. Lower jaw mottled in front with 
brown. Lateral fold brown, conspicuous. Legs barred transversely. Length 
1% inches. 
The Wood-frog is, in the mind of the writer, the most beau- 
tiful of the frogs. It cannot be confused with any other species 
when the markings are considered. It is an anomaly among its 
brethren inasmuch as it is never found in the immediate vicinity 
of water after the eggs have been laid in the early spring. Its 
home is among the fallen leaves of an upland woodland where it 
lives a solitary life. It is extremely hard to distinguish among 
the leaves as protective coloration is so well developed. 
Kirtland (’38) gives the following note under this species : 
‘‘Tt is impossible to move in our Ohio woods during summer 
without stepping on them, they are so abundant.’’ Whether this 
was meant to apply to the whole of Dr. Kirtland’s period of 
observation or to a limited period is not evident. What Is evi- 
dent, however, is that there has most certainly been a marked 
change in the distribution of the species since 1838, for as it 
occurs now in our State it is found as isolated individuals. Only 
during breeding seasons do they become in any sense gregarious 
and this only for a few weeks in early spring. 
Found over the entire State, but erratic, occurring only as 
isolated individuals.
