224 Frogs of the Okefinokee Swamp 



Two taken July 8, 1922, were: one fully transformed 8 mm.; one 8.5 mm. 

 (with tail 1.35 mm.). On July ig in another place we found five transformed 

 and transforming individuals and 19 mature tadpoles. The five were: three, 

 8.5 mm.; two, 9 mm. 



On July 18, 1922, in Murray Bay found 29 transformed Pseudacris ocu- 

 laris; two, 7 mm.; seven, 7.5 mm.; nine, 8 mm.; six, 8.5 mm.; five 9 mm. 



All in all the size seems to range from 7-9 mm., one specimen 11 mm. 

 probably being abnormally large. Of 41 specimens two are 7 mm.; seven 

 7.5 mm.; ten 8 mm.; ten 8.5 mm. and twelve 9 mm.; 8 to 9 mm. being the 

 average and modal size. 



GROWTH 



At transformation these pygmies are 7-9 mm. in length. On July 18, 

 1922, we took 29 transformed frogs from 7-9 mm. and five adults: two males 

 1 1.5 mm.; one male 12 mm.; one male 13 mm.; one female 13 mm. — two size 

 forms 7-9 mm. and 11. 5-13 mm., the latter doubtless one year old. We have 

 some isolated specimens of males 13.5 mm . I n 1 9 1 2 the males were 12-13 ni™ . 

 one female 15.5 mm. 



Cope gives .62 of an inch for total length. Our female 17.5 mm. is .70 of 

 an inch and may represent an approximation of the maximum, though I 

 am positive I have seen larger specimens. 



In 192 1 on May 16, four 12 mm., four 13 mm., and one 11.5 mm. males and 

 three females, 12 mm., 13.5 mm., and 17.5 mm. were taken. On June 23, 

 one male 14.5 mm. was taken. On July 7, we have 13 mm. cf, 14 mm.cf , 

 16 mm. cf. On July 8, 13.2 mm.d^ and 15 mm.d^. On July 13-17 we took 

 i4mm.<:f , 14.8 mm. cf, 15 mm.cf , 17 mm. 9. On July 17, one more set of 3 

 pairs give 13.4, 14, 15 mm. cfs and 15.5, 16, 16 mm. 9 s. Miller's group 

 (U.S.N.M. 7(034-41) of eight males 14- 15.5 mm. look comparable to the 

 17.5 mm. female above and our 1912 female of 15.5 mm. or the 1921 i4mm.-i7 

 mm. material. 



The evidence seems to point to 7-9 mm. for transformation; 11. 5-13. 5 for 

 I st-y ear-olds; 14-17. 5 mm. for second-year-olds. Possibly 11. 5-17. 5 mm. all 

 represent first-year-olds. 



FOOD 



We have made no study of this phase nor has any other naturalist. The 

 food of these brownies of our frog species would be very interesting to study; 

 must be minute insects, spiders, etc. Those who wish to work with the 

 smaller insect forms ought to find this species a good collector for entomolo- 

 gists. 



ENEMIES 



On May 17, 192 1 on Billy's Island we found a fine Thamnophis sackenii 

 (Ribbon Snake) where little chorus frogs were in grassy, sedgy, pipewort, 

 heath cover. This species must be a common prey for many snakes of the 

 ponds, bays and moist pine barrens and for other animals as well.
