distinct light line along the jaw. 



Voice: It is a peculiar cicada note in chorus, producing a con- 

 tinuous stridulating din which goes down the piney woods like a 

 wave. The call in the trees is il Kek" at intervals, but near the water 

 is speeded up to 6-7 a second, with 60-70 calls without deflation of 

 the throat. In a large congress these calls can drown out even the 

 shrill trill of Bufo quercicus, the little oak toad. 



Breeding: They breed from April 20 to Sept. 1. The eggs are in 

 groups of small films on the surface or just below it attached to grass 

 blades or floating roots, the jelly loose and sticky, the eggs brown and 

 yellowish, their size 1/30-1/25 inch (0.8-0.9 mm.), the inner envelope 

 1/16-1/12 inch (1.4-2 mm.), the outer envelope not distinct, 1/6-1/3 

 inch (4-6 or 8 mm.). The eggs hatch in 3 days. The tadpole is small, 

 1 1/3 inches (23 mm.), its tail tip acuminate, and free of spots, the 

 lower musculature with a light stripe. Many have bright red in their 

 tails. The tooth ridges are 2/3. After a tadpole period of 50 to 75 

 days, they transform from June 16 to October, at 1/2 inch (13 mm.). 



Notes: May 19, 1921. Okefinokee Swamp, Ga. On my way back 

 from a trip to Crosby pond, at 6 p. m. near the remains of an old 

 cypress pond in piney woods, I saw a female Hyla femoralis hopping 

 along into saw pahnetto. It was as whitish gray as any Hyla versicolor 

 I ever saw. The spot in the middle of back showed beautifully, as did 

 also the spot between the eyes. I held it to look at it. It leaped away 

 on the gray sand. I had a hard time seeing it, it matched the gray 

 sand so well. In one minute since its capture, it had darkened con- 

 siderably. 



In denser cover 9 inches high with small saw palmetto and small 

 bushes, I found a half grown Hyla femoralis. It was green on its back 

 (very suggestive of H. squirella, which strangely enough we don't 

 get here). 



May 21. In the compartment of Hyla femoralis ', most of specimens 

 (including one little half grown one) green when captured, are Van- 

 dyke brown or moss brown. The adults are not often green, but their 

 transformed life frequently starts in a green livery. 



A captive female in a jar, June 19, is pale light mouse gray on the 

 back with no markings revealed. 



On April 23, 1921, the boys found two on a rail fence at 2:30 p. m. 

 The next day they brought three more from the same fence. On April 

 26, the boys found some more Hyla femoralis in the rain barrels 

 along the railroad and near the company's woodpile. In a pine near 

 camp about 15 or 20 feet up on the end fork of large branch is a 

 Hyla femoralis male. It doubtless is the one we have heard ever since 

 we have been here.
