24 FAMILIAR LIFE IN FIELD AND FOREST. 



from the nose to the shoulder. The eyes are large 

 and prominent, the nose is pointed, and the general 

 color of the body above is yellowish green marked 

 with oval sjyots of olive margined with bright yellow. 

 These spots are arranged in two rows on the back, 

 and in two others less distinct on the sides. Under- 

 neath, the body is silver-white at the mouth and yel- 

 low-white at the abdomen. There is a characteristic 

 longitudinal band on the front of the thigh. 



This species is found in great numbers in the 

 swamps that border the creeks and rivers of the At- 

 lantic coast; but inland, except in the Mississippi 

 Valley, it is rather rare. According to Professor 

 Cope, with the Acris gryllus it is the first species 

 heard in spring, and although a single voice is not 

 loud, the noise produced by thousands of them close 

 at hand is deafening, and can be heard many miles 

 away. This frog " clucks " almost exactly like a hen, 



and in about the same key : j.-,-

number sounds more like a 



number of ducks quacking, but not without a de- 

 cidedly musical ring. I can not, of course, indicate 

 what difference there may be between the voices of 

 the species proper {Rana virescens or Ranahalecina) 

 and this subspecies, but I am inclined to believe that 

 there is none.
