The Green Frog 



^^y- 



there may be a well-defined band of the brilliant green on the 

 sides of the upper jaw below the eyes and ears, but elsewhere the 

 green is replaced by dull olive. (For colouration 

 of the Green Frog, see Colour Plate XIII.) 



The head is narrower than that of the 

 Bullfrog, but it is unusually thick through. 

 (The head of the female is narrower than 

 that of the male.) The eye is very large and 

 bright, with a golden iris and an oval 

 black pupil. The ear of the male is much 

 larger than the eye. (Fig. 229.) It is a 

 conspicuous flat brown circle with a yel- 

 low spot at the centre. The ear of the 

 female is smaller — about the size of 

 the eye — and lacks the yellow centre. 

 (Colour Plate XIII.) 



The Green Frog moults the 

 skin four or more times each year. 

 If the frog is out of the water when 

 the moulting takes place, the pro- 

 cess is like that of the American 

 Toad and of the Leopard Frog, 

 and the skin is swallowed. If the 

 moulting takes place in water, the 

 skin may float oif in large 

 patches and is not eaten. 



A small pond on a sunny 

 day about the middle of April 

 is a scene of much beauty and 

 of great activity. There is a
