Duration, night or day. On the evening of Apr. 24, 192 1, we went to 

 Moonshine Pond "Where we heard Hyla femoralis in the trees. In the pond 

 we heard one Hyla cinerea calling. No end of Acris calling. Some Ra7ia 

 sphenocephala and plenty of Bufo lentiginosus began calling later. This at 

 7:30 P. M. Later captured on lily pads 5 calHng males of Hyla cinerea. In 

 same place took my first Acris pair in Okefinokee Swamp but they got away 

 from me. In the pond were plenty of water lilies and water pennywort 

 (Hydrocotyle)." 



On the following day at 8:00 p. m. and later in another pond "on the lily 

 pads and vegetation-carpet were untold numbers of Acris gryllus. The male 

 often would keep the sac much inflated even though not croaking. Finally 

 found a pair in axillary embrace. These were put into a bottle but they 

 broke. At camp they were mated." 



On May 14 in another pond at 8 : 00 p. m. "The Acris were calUng loudly. 

 We found among lizard's tail {Saururus cernuus) on the sphagnum surface- 

 mat, a pair. They were resting quietly. Put them in a butter jar. The top 

 of the jar had a small hole about which we had forgotten. When next we 

 looked the pair had escaped. The next pair we saw amongst iris or sphagnum
