TURTLES AND BATRACHIANS OF THE LAKE REGION. 517 



17. Rana clamilans Latreille. 

 Green Frog. 



The Green Frog is well known throughout the eastern part of the United 

 States. At Lake Maxinkuekee it is common. Examples are occasionally 

 seen along the lake shore. It is much more common, however, about springs, 

 pools and creeks. Of about 25 examples obtained 4 were caught at the edge 

 of Lost Lake, 5 in Aubeenaubee Creek, 3 in Norris Inlet and 4 in Lake Maxin- 

 kuekee. 



This frog is more aquatic than the Leopard, Marsh or Wood Frog, and 

 does not often stray far from water. Its favorite haunt is the edge of some 

 creek, sprnig or pool, where it plunges with a surprised chung, at the first 

 alarm. It makes straight for the bottom and usually a bit of stirred up mud 

 shows where it has landed; or, where leaves are present in the bottom it works 

 its way under these. It can remain under water some little time without 

 discomfort. As its tadpole does not develop during the first year, this frog 

 does not spawn in shallow pools, but usually chooses some place where the 

 water is permanent. The tadpoles — rather large grayish creatures — can be 

 found in muddy pools and creeks. 



The Green Frog makes its appearance early in the spring and can be 

 seen until late in the autumn. A few dead ones were seen during the Avinter 

 and early spring, the first live one was seen April 15, and they were noted as 

 late as October 9. Many tadpoles were seen in Hauk's Marsh which seems 

 to be one of their favorite breeding places. The call of the Green Frog is a 

 repeated "thrum, thrum, thrum," usually heard late in the evening or at 

 night. They began thrumming about May 5, and continued until as late as 

 August 26. 



The Green Frog is excellent as an article of food and grows larger than 

 the Leopard Frog. It is occasionally seen on the markets, not so frequently, 

 however, as the Leopard Frog, because it is much more difficult to capture. 

 In the autumn of 1906 large numbers of these frogs were seen to jump into 

 pools in Overmeyer's and Culver's woods, but though these pools were 

 thoroughly dredged with a dip-net none of the frogs came to bag. This 

 frog exhibits a marked variation in the color of the underside, some of them 

 being plain white, others a rich yellow color; this difference seems to be merely 

 an individual variation. They also vary greatly in the size of the tympanum. 

 It is sometimes very difficult to distinguish this species from the young of 

 the Bullfrog, as they greatly resemble each other in general appearance. 

 The Green Frog has the glandular folds on the back more or less distinct and 

 the web of the foot not reaching the tip of the foiu-th toe, and can be always 

 distinguished by these characteristics. The following brief description gives 

 the details more fully. 



Green or brownish, brighter in front; generally with irregular small black 

 spots; arms and legs blotched, yellowish or white below; tympanum large;
