Bujo quercicus 129 



July 13 and 18. The earliest record of eggs we have in 192 1 or 1922 is June 4. 

 The intervals from June 4 to July 13 or 18 are 39 and 44 days. A period of 

 33-44 days does not seem unreasonable for such a summer breeder and shallow 

 water inhabitant though our evidence is slender (see tadpoles General Re- 

 marks) . Since the above was written we find that we captured a pair July 3 . 

 They laid July 4. The tadpoles were raised in camp and some went through 

 to transformation by August 12 or 39 days after egg laying. 



TRANSFORMATION 



Period. In 192 1 we recorded approaching transformation July 7. In 

 1922, on "July 12 found Bufo quercicus transformed in the edge of a pond in 

 wet pine barrens." On "July 13 around Coat Bet (Hyla gratiosa) pond on its 

 south side found plenty of young toads (Bufo quercicus) transformed. They 

 were near the edge of the pond but in the moist pine barrens especially in 

 clear areas". On July 18 (1922) found a few transformed around the shallow 

 edges of Murray Bay (a sphagnum swamp overgrown with heaths and even 

 trees). On August 16, 1922, near Callahan, Fla., we found them transformed. 

 At Trader's Hill Pond (1/2 mile west) on July 3, 1922 we found them mated. 

 Eggs from these were carried to camp. The transformed toads from this 

 series transformed August 1 2 . 



In 1922 we then have transformation records from July 12-August 16. 



Size. Deckert (1914 b, No. 9, pp. 2, 3) is the first to record anything on this 

 phase. The metamorphosis he holds to be very rapid. Hence one would 

 expect little pigmies of transformed frogs. "The young toads, when fully 

 developed, are 1/4 inch or less in length. The adults measure: male, i inch; 

 female, i 1/8 or i 1/4 inch". 



On July 18, 1922 we secured five little toads at Murray Bay, Folkston, Ga., 

 measuring 7, 7.5, 7.5, 8, 8 mm. respectively. They had "no stripes down back, 

 were prickly all over". On August 16 near Callahan, Florida, we took one 

 8 mm. long. On July 30-3 1, 1922, we secured one on Chesser Island, 10.5 mm. 

 long. It is just past transformation. The note on it reads: "Makes me think 

 of B. dehilis at this size". On August 12, 1922 we succeeded in transforming 

 this species at 7 mm. in length. Our largest series came July 12, 1922. Some 

 of them measured as follows: 6, 6, 5, 7 (median stripe), 7 ,7, 7, 7.5, 8, 8, 8, 8, 8, 

 8.5, 9, 9 (stripe down back), 9.5, 10 mm. respectively. Some of the larger 

 were slightly past transformation. The very tuberculate under surface of 

 forefoot suffices to distinguish it from Bufo terrestris. 



GROWTH 



This species transforms at 7-8 mm. On July 30, 1922, on Chesser Island, 

 Ga., we secured one 10.5 mm. and the next day in the same place one 13.5 mm. 

 In 191 7 at LeRoy, Ala., we took 9 specimens 11, 12, 13, 14, 14.5, 15, 16, 16, 

 16 mm. respectively and one 21.5 mm., possibly two age groups. 



In the swamp we have isolated records such as: July 9, 1922 one 16.5 mm.; 

 May 6, 1921, one 15.5 mm.; August 13, 1922, 14, 15, 16, 17 mm. examples.
