Habitat. — Distributed over the eastern United States 

 and Canada to the Plains. Found all over Missouri in 

 abundance. 



Habits. — This frog is found along the muddy banks of 

 brooks and ponds. Walking along a little stream, we may- 

 hear a sound, a high pitched cry, ahead of us and see a 

 frog jump into the water, hiding under the leaves and in 

 the mud. This is the Green Frog. Because of its peculiar 

 cry or scream, it was called the * * Screaming Frog. ' ' This 

 frog is more aquatic than most frogs with the exception 

 of the Bull-Frog. The Green Frog moults four or more 

 times each year. If not in water when moulting, it will 

 swallow the moulted skin like the toads and the Leopard 

 Frog. 



Mary J. Dickerson in her admirable book gives the fol- 

 lowing account: — ''During almost any of the warm 

 months of the year we may find Green Frog tadpoles 

 changing to the adults. The hind legs grow rapidly, and 

 may be conspicuously barred with dark color. The left 

 arm appears first, thrusting itself out of the breathing- 

 pore. Then the right one breaks through the skin. The 

 changes in mouth and eyes begin. The tail is slowly 

 absorbed. The ears are the last external sign to tell that 

 the change is quite completed. Most curious is the fact 

 that some tadpoles show the lateral folds and the coloring 

 of the adult male or female long before the change is com- 

 pleted, while others take on the frog form entire before 

 the lateral folds are well developed or before sexual color- 

 ing is evident." 



Bates of capture. — Mar. 21 ; May 1, 29 ; Aug. 13 ; Sept. 

 1, 17 ; Oct. 3, 26. July 4, 1904, while collecting in Dunklin 

 County, I came across a number of these frogs in a dark 

 cypress swamp, where they were hiding beneath brush 

 piles. All were of a dark color.
