202 Frogs of the Okefinokee Swamp 



EGGS 



(Not described). Doubtless like those of Hay's (Indiana), Morgan's 

 (Maryland), Wright's (New York) swamp cricket frog observations and those 

 of several other observers. We also have Pseudacris eggs from Texas and 

 tadpoles from several diverse parts but no eggs of P. nigrita as such are on 

 record. 



TADPOLES 



(Wherein these differ from Texas, Indiana, Maryland, New York and 

 Louisiana tadpoles has never been observed or recorded by any South Car- 

 olina to Mississippi naturalist or visitor to those parts). 



LARVAL PERIOD 



In the northern regions kindred species take 67 days (Hay's), 60-70 days 

 (Wright) or about two months as larvae. In 1922 we found none on June 

 14 on our arrival nor any thereafter. Most of the breeding must have been 

 over before April. 



TRANSFORMATION 



In general it must take place before June i. In the North the bulk of 

 larvae of the related species are transformed by June 15 or by the end of June, 

 and it must come earlier in Georgia. The northern forms transform at about 

 9-12 or 13 mm. 



GROWTH 



Possibly with transformation presumably from 9-12 or 13 mm. the frogs 

 taken June 15, 1922, which were 17 mm. are one-year-olds. Those taken 

 July 15 and 18 and August 16, 1922, were 22, 23 and 25 mm. Are they two- 

 year-olds and does the species breed at two-year-old stage or do some even 

 enter breeding after one year? We know not. 



ENEMIES 



This species cannot help being one of the abundant foods of snakes and 

 numerous foes in early spring through no definite records appear. 



AUTUMNAL DISAPPEARANCE 



Our latest records are: August records in 1921 and 1922, September 8, 

 1910, and September 11, 1919. 



AFFINITIES 



LeConte (1825, p. 282) placed Rana nigrita right after "Rana gryllus 

 (Savannah cricket)." Harlan (1825, p. 341; 1835, p. 105) repeats LeConte's 

 "indication" of a fuller description. Dumeril and Bibron (1841, Vol. 8, p. 

 509) places it in their new genus Acris with the "palmure des pied tres- 

 courte" as contrasted with "bein developpee" in Acris gryllus. 



In his Catalogue of Reptilia and Batrachia Holbrook (1849, Appendix p. 

 15) still uses Cystignathus.
