292 Frogs of the Okefinokee Swamp 



formed Hylafemoralis. They were green above." Or on July 27, 1922, "in a 

 pond where we heard Hyla gratiosa and took transformed green Hyla gratiosa 

 Mr. Pirnie found two transformed Hyla femoraUs, golden green and resting 

 on stems 1-3 inches above the water. If they were shaken off they swam to 

 another stem and climbed up. They were a prominent green but when trans- 

 ferred to a cocoa can they changed in five minutes to an almost black color." 



GROWTH 



In 191 2 we secured the following material: "On May 28-29, 1912, we took 

 one specimen, 17.75 mm. long, another on June 6-7, 19 12, 21.25 mm., a third 

 June 24, 19 1 2, 21 mm., a fourth from the edge of the swamp Sept 11, 1909, 

 18 mm., and a fifth, 16.5 mm. These measurements 16. 5-2 1.2 5 mm. from 

 June i-September 11 represent 10-12 months' old frogs." On February 9, 

 191 1, Professor J. C. Bradley took a 20 mm. at Waynesville, Georgia. 



In 19 1 2 on June 6-7 when a 21 mm. was collected two more were taken 

 31 and 36 mm. respectively. On June 24 besides the 21 mm. specimen we 

 have a 27 mm. and a 31 mm. specimen. On June 5 when a 25 mm. was taken 

 we also recorded 33 and 36 mm. specimens. On June 15 two specimens we 

 have respectively 26 and 31 mm. Possibly on this basis the one year olds 

 extend from 16.5-26 mm. 



In 1921 we captured transformation sizes from 11. 5-15 mm. On April 25 

 when we took a 20 mm. specimen we also captured 24, 26, 26, 28, 30 and 33 

 mm. specimens. On June 3-5 we had a series 20, 24, 25, 27, 27, 27, 30, 30, 31, 

 31, 32, 33, 33, 34, 34, 37, 37, 37, 4o mm. respectively. Or on May 21 a series 

 of four yielded 25, 28, 31, 33 mm. specimens. With the other material col- 

 lected in 192 1 the line between i and 2 years seems to be from 24-26 mm., 

 while :n 191 2 it is apparently 26-27 mm.; the line between second and third 

 years in 191 2 between 32-34 mm., and in 192 1 between 32 and 35 mm. 



In 1922 we took one specimen of 23 mm., two of 29 mm., and one of 34 mm. 

 On August 13 we secured a 19 mm. specimen on the Sugar House, St. Mary's, 

 Georgia. All the other lots begin with 32 or 33 or 29, 29, 28, or 27 mm. Two 

 series are: July 21-27, 28, 28, 28, 29, 30, 30, 30, 30, 31, 31, 31, 32, 32, 32, 32, 

 33, 33, 34, 34, mm.; July 11, 28, 28, 29, 30, 30, 31, 38 mm. The 1922 material 

 apparently separate at 25-26 mm. for the line between ist and 2nd years and 

 at 33-35 mm. for the Une between 2nd and 3rd years. 



Considering seasonal, yearly or sexual variations the evidence points to 

 10-15 mm. for transformation size, 17-26 mm. for ist year olds; 26-32 or 34 

 for 2 year olds; 32 or 34-40 mm. for 3 year olds. 



FOOD 

 This phase of its natural history we have not examined. 



ENEMIES 

 In 191 2 we summarized it thus: "This species was represented in the 

 stomach contents of one black snake {Coluber constrictor)oi onb southern 

 riband snake (Thamnpohis saimtus sackeni), of two garter snakes {T. sirtalis)
