the sides of throat and pectoral region sulphur yellow. The colored 

 area of throat is encircled with white on the inner side. The spots on 

 the side, chin, and rim of jaw are reddish brown. 



Structure: A large tree-frog of heavy build; skin granulated; head 

 broad and short; fingers webbed; large disks on fingers and toes; 

 prominent fold on breast; skin has marked secretion giving strong 

 persistent odor. 



Voice: The call is woody, deep, a curious tonk, tonk, like someone 

 pounding on a hollow, heavy barrel or hogshead. The call in the 

 ponds is Coat Bet. The call from trees as it approaches water is a bark. 



Breeding: They breed from March to August. The eggs are laid 

 singly on the bottom of the pond. The single envelope 1/10-1/5 inch 

 (2.3-5 mm.), is loose, glutinous, and indefinite in outline. The vitelline 

 membrane appears as an inner envelope 1/16-1/10 inch (1.6-2.5 

 mm.) in diameter, the egg 1/25-1/16 inch (1-1.8 mm.). The green- 

 ish tadpole is medium, 2 inches (50 mm.), and is the largest Hylid tad- 

 pole of eastern U. S. The tail is long, its tip acuminate with a flagellum 

 and the tooth ridges 2/3. The tadpole period is 40 to 70 days. They 

 transform from July to October, at 9/10-4/5 inch (14-20 mm.). 



Notes: "The Florida tree toad is a handsome species. ... It is 

 not very plentiful'anywhere, and rarely met with outside the breeding 

 season. During the latter time it comes down out of the trees and small 

 companies of from four to ten specimens, in widely scattered pools or 

 'bayous' attend to their breeding duties amid the 'loud calls of males.' 

 The call can be heard for over a mile, and sounds like a large gong, 

 or church bell, being of unusual depth, and very clear, with a second's 

 interval between each dual note. The male while singing, floats in the 

 water, the large vocal sac throwing the frog into a vertical position 

 with each utterance." (Deckert, 191 5, pp. 4, 5). 



While we were in the Okefinokee Swamp, Georgia, we usually 

 recorded this species as Barker, Barking Frog, or Coat Bets. The last 

 refers to the normal note in the breeding pools, the others to a puzzle 

 that perplexed us for two seasons. On July 15, 1921, on Chesser Is., 

 we heard of Coat Bet frogs, so named from the sound of their breed- 

 ing call. On July 16, during the morning, we heard a barking frog in 

 the trees south of camp. That night in a nearby pond was an immense 

 chorus of Coat Bets. In 1922, the barkers perplexed us even more. 



Not until July 26 did we solve the puzzle. About three miles 

 along the road from Chesser Island to Folkston we heard in the 

 evening in a cypress pond to the right of the road, some Hyla gratiosa 

 and beyond them, a barker or two. We went after the barker, and 

 found one in a small gum 4-5 feet, possibly 6 feet up. It is Hyla 

 gratiosa! I saw him do it. There were two more barkers besides the 

 one I caught. Several Hyla gratiosa were in the water calling normally.
