BATRACIIIANS OF THE VfCINITY OF NEW YORK 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.

small size. It is light brown above, with a dark brown spot on 



each side of the head. This spot extends from the

 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.

 apparent, however, and facilitates identification. Length of body, 

 2^ inches; total length, with hind limbs outstretched, 5! inches.
