THE CROAKERS. 23 



eight species, according to Mr. Boulanger, but of 

 these only six are common enough in our northeast- 

 ern States to attract our notice. These are : 



1. Rana viresoens virescens, the leopard frog ; a 

 subspecies of Roma vwescens [Rama haleoina, of other 

 authors), a bright-green frog found along our seacoast 

 and the adjacent country. 



2. Rana palusi/ris, a light-brown frog found in 

 cold springs and streamlets. 



3. Rana septentrionalis, a round-spotted frog 

 found in northern New York and the northwest. 



4. Rana clamata, the green frog, common every- 

 where. 



5. Rana catesbiana, the bullfrog, the largest spe- 

 cies of all, also common. 



6. Rana sylvatica, the wood frog, common every- 

 where in our woodlands. 



The prettiest fellow of them all 

 the leopard frog, Rana virescens 

 virescens, about two and 

 half inches long. A 

 bright copper - col- 

 ored line begins at 

 his nose and ends 

 at his eye ; a sec- 

 ond line of yellow- 

 Leopard Frog 

 ish white reaches IJtana virescens virescens).
