it is much move difficult to capture. In the autumn of 1906 large 

 numbers of these frogs were seen to jump into pools in Overmyer'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 dis- 

 tinguish 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 fourth toe, and can be al- 

 ways 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; glandular folds large; toes well webbed; 

 first finger not extending beyond second ; tibia and femur equal 

 1^ body. Length 3 inches,

RANA CATESBEIANA Shaw 



The Bullfrog was formerly rather common in sluggish streams 

 and ponds throughout the United States east of Kansas. At Lake 

 Maxinkuckee it is said to have been formerly abundant, but it has 

 been hunted until it is now rare. The method of hunting them 

 was by means of a bicycle lamp at night which so blinded them 

 that they could easily be picked up. 



This is the rarest frog about the lake, only six examples hav- 

 ing been seen, and of these only three were captured. One was ob- 

 tained near the Fish Commission station while seining for min- 

 nows at night. A lantern was in use which probably blinded the 

 frog. A large one was seen November 20 down by Norris Inlet, 

 at the edge of the water. It was somewhat torpid, but managed 

 to escape. On January 7, 1901, one of the ice-fishers saw a large 

 Bullfrog on the bottom in several feet of water off the Gravelpit. 

 He cut a hole in the ice, let down a hook and pulled out the frog. 

 It was too torpid to move. One was obtained April 15, 1901 (No. 

 35445, U. S. Nat. Mus.). On May 1, a large one was seen in the 

 pond back of the Winfield cottage, and on September 30, 1907, one 

 was seen basking on the shore of the Outlet about two miles below 

 Lost Lake.
