148 Frogs of the Okefinokee Swamp 



Detailed laboratory studies by Mrs. Wright are as follows. "July 4, 1922, 

 Starling Branch Bufo terrestris eggs. No inner envelope — no partitions — just 

 one homogeneous tube. 8-1 1 eggs in 30 mm. Black with small grayish-white 

 vegetative pole. Tube 2.8 mm. in diameter." 



"Cannot find inner envelope or has inner tube swelled to meet outer tube. 

 Finally found inner tube but not very well marked. Inner tube present but 

 close to outer tube." 



In another note we find "Tube inclined to be scalloped due to indentation 

 between each two eggs. Axis of developing vitellus longitudinal with tube." 



Or "vitelli 2.4-2.6 or 2.8 mm. apart. In others 1.8-2.0 mm. apart." 



Other notes are: "vitelli i.o, 1.2 or 1.4 mm., average 1.2, mean 1.2 mm.; 

 inner tube 2.2-3.4 mm.; outer tube 2.6-4.6 mm. 6 eggs in 20 mm.; 7 eggs 

 in 20 mm.; 7 eggs in 30 mm.; 8 eggs in 30 mm. and one 12 eggs in 30 mm." 



Our final characterization in 1924 (p. 380) became the following: "Eggs in 

 files. Files long (several feet in length or often a meter or more long) ; vitellus 

 1.0 to 1.4 mm.; tube diameter 2.6 to 4.6 mm. Inner tube present. 7 or 8 

 eggs in 30 mm. (i 3/16 inches); distinct space between eggs; no partition 

 apparent; tube inclined to be slightly emarginate between the eggs; inner 

 tube 2.2 to 3.4 mm.; outer tube 2.6 to 4.6 mm. Egg complement, 2,888." 



Dangers. If the eggs are laid in shallow water i to 4 or 5 inches from the 

 surface the danger of drying up in many ponds is grave to say nothing of the 

 transitory localities the species picks in periods of downpours. 



HATCHING PERIOD 



On April 24, 192 1, we found egg laying with water temperature 71°, 

 surface water 81° at 11:30 a. m. On April 28 we make the note "Bufo 

 lentiginosus eggs laid night of April 23-24 and morning of April 24 hatched 

 a day or so ago. Collected April 28, 4:00 p. m. Temperature 82°." This 

 implies 2 to 3 days for hatching. On June 22 found some eggs at Starling 

 Branch crossing presumably laid June 19. These were about ready to hatch. 

 They were in the open. But at Camp Pinckney in the shade on deeper water, 

 turpentine water pits they were not hatched though we make the note they 

 must have been laid June 19. These records would imply 3 or more days for 

 hatching. Our data is scanty. Hatching apparently comes in 2-4 days. 



TADPOLE 



Color description from life {July 7, 1921). General color is black with 

 scattered dots which are pale purplish vinaceous. Venter black with few 

 scattered light purplish vinaceous spots but not clustered to make one con- 

 tinuous mass of color as on the belly of B. quercicus. 



Tail. Upper crest spotted but not so strongly as in Bufo quercicus. Lower 

 crest almost clear of spots. Lower edge of muscular part white or light chalce- 

 dony yellow. 



General appearancQ. Body small (26 mm.) ovoid broader nearer vent than 

 eyes. Dorsal aspect shows body decidedly tapers ahead of the eyes. Dorsal
