244 Frogs of the Okefinokee Swamp 



from choruses we heard June 26-30, 1923, and previous observations by others 

 the transformation doubtless extended from June 29-September i with 

 the majority changed into frogs before August i. 



Size. "When the tail is nearly absorbed, and they leave the water, they 

 are about 25 mm. long and of a dull olive green. They grow lighter, that is, 

 brighter green in hue with the disappearance of the tail until the little frogs 

 which in length of body are 15 mm., resemble the mature individuals. The 

 white that margins the green of the back and extremities is not so conspicuous 

 as in the adults, and the saffron of the under parts is wanting in those that I 

 have examined." (Davis, 1907, p. 50). 



In color the transformed frog looks much like that of Hyla femoralis or of 

 Hyla squirella. The dark vitta does not extend along the side but is a pur- 

 plish area before and back of the eye just before the tail is entirely absorbed. 

 Not until the four legs were acquired did our froglets have green appearing 

 on the back. 



The range in body length of one collection of 10 individuals is 11. 5- 13.0 

 mm.; average 12.0 mm.; mode 12.0 mm. Our transformation sizes, therefore, 

 prove slightly smaller than those of Mr. Davis. The two records combined 

 give a range of 11-15 mm. for transformation size. 



GROWTH 



This species begins as little froglets at 11. 5-15 mm. in body length. Dr. 

 Barbour has material, 13 specimens (M. C. L. Nos. 3218, 3577-79, 3 55 1-60) 

 from Lakehurst most of which was taken by himself and F. K. Barbour. 

 These measure 35 d^, 36 d", 36 cf , 37 cT, 37 d", 37 d", 38 d", 38 d", 38 d", 

 38 cT, 38.5 d^ mm., 38.5 d^, 40.5 d^ ; and one female 44 d^ mm. This gives a 

 range of males from 35-40.5 mm. The Nobles (A. M. N. H. Nos. 16960-83) 

 had males 35-38 mm. and females 38-44 mm. From comparative experience 

 they may prove 3 years old, but our collections and collections in general 

 have so little material between 15 mm. and 35 mm. that it is useless to attempt 

 an approximation of this question. Possibly some adults of second year from 

 26 or 27-33 or 34 mm. may breed. 



FOOD 



Noble and Noble (1923, pp. 448, 449) record that "The stomachs of ten 

 males which were captured during June while caUing from bushes or low 

 trees contained the following food: 5 grasshoppers (two species); 2 beetles, 

 3 ants (two species), i dipterous insect, 2 dipterous pupae (tabaniid?), and 

 some unidentifiable insect remains. None of the specimens taken in embrace 

 contained food in their stomachs, but only a few pairs were killed immediately 

 after oviposition." Dr. Burt Green Wilder made extended notes on food and 

 food prehension in this species. He kept a male (sent by Dr. James P. 

 Chapin) from July 21, 1906 to November 21, 190,8, when the creature was 

 killed. It, therefore, lived in captivity over two years. Unfortunately his 

 notes are not to be found. This is the same specimen L. A. Fuertes painted.
