are conspicuously barred; and the throat, breast, and much of the 

 under side of the hind legs is heavily dotted with dark. The males 

 have yellow on folds, tubercles, iris, axilla, and groin, while the 

 females have little or no yellow. 



Structure: Wedge-shaped body, wide in head and slender in waist; 

 tubercles on back; thumbs of males somewhat enlarged and darkened; 

 males with vocal sacs from angle of mouth halfway to the groin. 



Voice: The lateral pouches on each side of the neck, extending 

 posteriorly halfway down side of body, inflate to a size nearly equal to 

 that of the frog's head. The call is a deep hollow roll, intermediate be- 

 tween a snore and a groan: yawh h h h h, yawh h h h h. 



Breeding: They breed from April to August 17. The eggs are in a 

 large plinth-like mass about 6 X 8 inches and 1 1/2 inches deep. The 

 egg is 1/12 inch (2 mm.), the outer envelope 1/5 inch (5.2 mm.), the 

 inner 1/8 inch (3.8 mm.). They hatch in 4-4 1/2 days. The tadpole is 

 large, 3 3/8 inches (84 mm.), full and deep bodied, the venter strongly 

 pigmented, the tail long. The color may be greenish, with yellowish 

 on the top and sides of the head, the belly yellowish. The tooth 

 ridges are 2/3. After a tadpole period of 85 to too days, they trans- 

 form from August to November 1, at 1 1/12-1 1/2 inches (27-38 mm.). 



Notes: In their normal all-the-year habitat, the sandhills and turtle 

 burrows, they are seldom seen unless one deliberately seeks them. 

 They usually rest at the mouth of the burrow, sometimes a foot or so 

 down the decline, more rarely a foot or more from the incline, or may 

 be on a little clear smooth place, 6 inches in diameter, a short distance 

 from the hole. One area we visited frequently. From mid-forenoon to 

 mid-afternoon, they were seldom out. On July 2, 1922, we visited this 

 area at 2:30 and noon and found only one out, but at midnight, we 

 readily found eight. 



July 17, 1 921. Okefinokee Swamp, Georgia. We sought out a 

 group of gopher frogs we were hearing in the shallower western por- 

 tion of the pond. One was beside a cypress tree in a depression of 

 fibrous roots. I put the light on its nose and tried to push it back with 

 my fingers. Then it leaped. At the base of a pine on a pile of chips 

 1 1/2 feet above the surface was another croaker. After a time, it 

 would "bat" its eye toward the bullseye. These frogs were not hard to 

 catch when discovered, but they were shy. Often when first put under 

 light they would sink back into the fibrous roots, depressions and 

 covers. One was spread out in the water amongst the spice bushes. 

 The influence of nearby croakers seemed to stimulate this one as it 

 does others. We caught several, put them in a bag, and induced these 

 to croak. In this way the sprawled-out specimen responded beauti- 

 fully with his croaks.
