BARRACHIAN S OR THE VICINITY OF NEW VORK 205 
The eggs of the Bull Frog are laid in May. During the latter 
part of July or in August of their second summer the tadpoles 
acquire limbs and leave the water as perfect frogs. 
The Wood Frog, Rana sylvatica Le Conte (Fig. 27), is of 
small size. It is light brown above, with a dark brown spot on 
each side of the head. This spot extends from the 
snout through the eye (darkening the lower half of the 
iris), covers the earplate and adjacent area and ter- 
minates in a sharp angular outline with a fold of the skin behind 
Wood 
Frog.

the base of the fore limb. A whitish line in strong contrast with 
the dark color on the sides of the snout traverses the upper lip. 
There is a smaller dark spot near the base of the fore limb. The 
hind limbs are indistinctly banded on the upper surface. The 
abdomen is silvery white. 
Two well-defined ridges, or vein-like folds, extend down the 
back of this easily-recognizable species. In different specimens 
the body color varies somewhat, some are distinctly reddish. 
The characteristic dark spot on each side of the head is always 
apparent, however, and facilitates identification. Length of body, 
21 inches; total length, with hind limbs outstretched, 5? inches.
