fold from tympanum to base of arm. 



Voice: The voice is loud and at a distance sounds like a cow-bell. 

 The individual call is quonk, quonk, quonk, quank. To some ears, 

 fried bacon , fried bacon. To Deckert, grab, grab, grabit, grabit. 



At Flatwood, Ala., 1917, after 6:30 p. m. in a drying-up swampy 

 pond, we heard a chorus which sounded like cow-bells at a distance. 

 To one member of the party, it sounded like an exhaust running into 

 an oil well pipe. We took one with the aid of a flash light. ... It was 

 on some bushes and its sides and throat looked like a pink ball. 



Breeding: They breed from April 15 to August 15. The black or 

 brownish and white or cream eggs are in small packets or films at or 

 near the surface attached to floating vegetation. The outer envelope 

 is poorly defined, becoming part of the mass. The egg is 1/30-1/16 

 inch (0.8-1.6 mm.), the inner envelope 1/12-1/8 inch (2.2-3.4 mm.), 

 the outer envelope 1/8-1/6 inch (3.6-4 mm.). The tadpole is medium, 

 1 3/5 inches (40 mm.), its tail long and acuminate, its body green with 

 a sulphur or ivory stripe on the side of the head from snout to eye. 

 The tooth ridges are 2/3. After a tadpole period of 55 to 63 days, 

 they transform from July 2 to October, at 1/2-11/16 inch (12-17 

 mm.). 



Notes: The same conditions do not always produce the same 

 coloration. In one case, we had many Hyla cinerea in a botany drum. 

 All were light green except three; one of which was almost black, 

 another olive green or dark green, and the third yellowish green. . 



At night many individuals are seen to be fairly covered with cer- 

 tain tiny insects that are common in the ground vegetation. Some 

 that were collected proved to be harmless flies (Oscinia longipes). 

 Their perching on the frogs is probably accidental. 



June 14, 1930. Beeville, Texas. All of a sudden several Hyla 

 cinerea began croaking around the pond. They were on nearby 

 mesquite bushes or on small dead plants above the water. 



June 15, 1930. Beeville, Texas. At night. Acris began first, soon 

 to be joined by R. pipiens, then came H. cinerea, and finally one or 

 two Gastrophryne texensis. . . . We caught several H. cinerea. In one 

 mesquite or papilionaceous plant we found 2 males facing each other, 

 and caught each by putting the light between my legs, and grabbing 

 with each hand. H. cinerea were about 1 or 2 feet above the water. A 

 beautiful brown garter snake (Thamnophis eques) was coursing 

 around the pond, ostensibly for frogs. 



June 17-21. Brownsville-San Benito, Tex. In various resacas 

 were several choruses of H. cinerea.
