332 Frogs of the Okefinokee Swamp 



The dimensions of the largest tadpole are: 



These tadpoles have long tails, 1.75-3.5 in the length of the body and 

 scarlet or vermillion in color, with black blotches more prominent near the 

 margins of the crests. The intenstine does not show through the skin. 



LARVAL PERIOD 

 In the North it takes 50 or 60 days for development from the egg to trans- 

 formation. Sometimes the period may be only 45 days or in other cases as 

 great as 65 days. In the Okefinokee country the period may be shorter. 



TRANSFORMATION 



Period. The only transformation we found came June 27, 1922 at Camp 

 Pinckney. "In the Hyla versicolor pond some are almost transformed." 

 This is almost a month eariier than any we have recorded at Ithaca, N. Y. 

 (July 1 8- August). Were they (June 27, 1922) tadpoles from eggs laid in the 

 first (May 1-5), middle (May 15-22), or last of May (May 28-31) when rain 

 prevailed, either 57 or 52 days or 42-36 days or 33-28 days? 



Size. In 1914 the size of 87 specimens at Ithaca measured 13.6-20 mm. 

 at transformation, the average 1.6 mm., the mode 16 mm. The material 

 transforming June 27, 1922, at Camp Pinkney measures as low as 13 mm. in 

 body size. 



GROWTH 



In 1920, we concluded that tree toads were 14-20 mm. at transformation, 

 average 16 mm.; at i year old 20 mm.-3o mm., average 25 mm.; at 2 year old 

 30-41 mm., average 35 mm.; at 2 year old 41-51 mm., average 45 mm. If 

 they transform at 14-20 mm. the specimen we found at Ithaca, May 16, 19 15, 

 must have been transformed at the smaller size of 14 mm. It measured 18.5 

 mm. and was doubtless of the previous fall's transformation. The smallest 

 breeding frog (outward signs) was a male taken at Petersburg, Va., June i, 

 1 91 7. The males taken the same day at Dinwiddle were 34, 35, 37, 38, 39, 

 40, 41, 42 mm. The frogs taken at Camp Pinckney August 16, 1921, June 16, 

 1922, and August 11, 12, 1922 measure 39, 40, 41, 42, 42, 43, 43, 44, 44, 45 all 

 males and one female 53 mm. Transformation came at 14-20 mm. Possibly 

 20-30 mm. represents one year olds; 30-42 mm. represents two year olds; 

 42-53 mm. three year olds; 53-59 mm. four year olds. The largest we have is 

 a female 59 mm. in length.
