ACRIS GRYLI^US , the cricket frog: This frog is found largely in the Central States, 

 from Michigan to Dakota and south to Texas. It is very small, the head and body never 

 measuring more than I4 inches. The toes of the hind limbs are webbed. While the color 

 varies there is always a triangular mark between the eyes 

 and a dark oblique stripe on the side of the body. The 

 male's throat skin is grayish-yellow, and its fingers are 

 shorter and body smaller than that of the female. 



Breeding takes place in shallow, plant-filled water during 

 May to July. The eggs are laid singly and are attached to 

 stems and twigs. Metamorphosis occurs about the middle 

 of September. 



HYLA CRUCIFER , the Spring Peeper. This small frog is 

 found all along the eastern coast and abundantly in Florida. 

 The adults rarely exceed 1 3/8 inches in length but may be 

 recognized by their high, shrill, clear call so frequently 

 heard in the spring during breeding. There is an oblique 

 cross on the back, the general color being brown of vari- 

 ous shades. The digits are not webbed as they are in the 



genus Rana, but the tips of the toes have discs for climb- ^ the cricket frog, 



ing on smooth surfaces. The thumb of the male bears a (Courtesy C. H. Pope
