348 Frogs of the Okefinokee Sivamp 



tion we have one note on transformation as follows: "28-35-(?) mm. In the 

 American Museum material (Nos. 5930-32, 5896, 5897) are five specimens 

 from N. P. Fry of Eureka, Florida. These are 32, 27, 28, 33, 36 mm. respec- 

 tively and from near Arlington, Florida, Thomas Hallinan takes a specimen 

 31 mm. These all must be at or near transformation. Possibly transforma- 

 tion extends from 27-35 or 36 mm. It makes its transformation size com- 

 parable to the upper part of the transformation range of Ra7ia pipiens (19-28 

 mm.) or of Ra7ia sphenocephala (19-33 mm.). It is evident if we had enough 

 material that the mode and average of Rana aesopus would be higher than 

 that of Rana pipiens (22 mm. and 24 mm.) or of Ra7ia sphenocephala (25 mm. 

 and 23 mm.). 



GROWTH 



We have only transformation and adult sizes. The intermediate stages we 

 missed. From analogy one would believe that at least 3 years were required 

 for their maturity and possibly 6 years for the maximum sizes. Deckert 

 (1914, p! 3) writes ''The one-year-old frogs of this species I have repeatedly 

 caught, wandering from the high ground and its burrows into the swampy 

 meadows below, where the insect hfe is more abundant. On being discovered, 

 they will not dash away with long leaps, like other frogs, but squat close to 

 the ground, motionless, like some toads, and are then easily picked up." 



This species apparently transforms at 28-33.5 mm. Our adult material 

 begins with sizes of 66, 68 mm., 73, 82, 85, 95, 95, 108 mm., and it seems to 

 sort into groups of 68-73 mm., 82, 95 mm. and 108 mm. 



In Levy Co., 1892, J. Hurter (U. S. N. Mus. Nos. 57533-35576-78) 

 collected 62, 69 mm., 71 and 74 mm. specimens — apparently one group 62-74 

 mm. In July, 1893 (U. S. N. Mus. No. 20513) H. G. Hubbard collected a 65 

 mm. specimen and on June 20, 1894, two specimens (U. S. N. Mus. Nos. 

 21702, 21703) 71, 73 mm. respectively or one group 65-73 mm. At Auburn- 

 dale, Fla., N. R. Wood secured in 1917 (No. 59413) a 74 mm. specimen and 

 another in April, 19 18, 49 mm. in length, apparently two groups. The type 

 is 52 mm. and they have a specimen 83 mm. Boulenger's material was as 

 follows: 68, 73, 77, 80, 82, 84, 85, 88, 91, 93, 95 mm. respectively. One lot taken 

 at same place is 68, 84, 85 and 93 mm., two groups 68 and 84-93 mm. ; another 

 lot is 73 and 95 mm., two groups; and another lot 80 mm., apparently one group. 



The American Museum material seems to sort: 27-36 mm.; 49-55 mm.; 

 62-76 mm.; 78-85 mm.; 90-102 mm. 



In the Museum of Comparative Zoology series were 12 specimens taken 

 in 1919 at Orlando by Dr. Thomas Barbour. These are 58, 61, 63, 64, 67, 67, 

 68, 70, 70, 71, 76, 93 mm. The same year Dr. Barbour secured several 10 

 miles north of West Palm Beach, Florida. They are 82, 86, 89, 89.5, 90, 94. 

 Other records they have are: 



No. 3574 Fruitland Park, A.G.Reynolds, 1914, 40 mm. 



5137 Gulfport, Fla. " " " 1919, 52 mm. 



7081 " " " " " 1920, 41 mm. 



5938 Sebastian, Fla., George Nelson, 1919, 74 mm. 



4907-10 New Smyrna, Fla., March 1919, 79, 86, 89, 91 mm.
