Considering 12 choruses from April 23 to July 26, 192 1, we have for nearby 

 Weather Bureau Stations maxima 72°-94°, usual range 8i°-89°, average 84°, 

 mode 85°, for the day before; and minima from so°--j6° (one 45°), average 

 61°; for the day of the record, maxima from 8o°-92°, average 86°, mode 86°; 

 minima of 5o°-74°, average 66°. Heavy rains of .90-2.80 preceded most of 

 the choruses or at the time of the chorus. In the last of April maxima of 

 8i°-89° and minima of so°-62° obtained during croaking whether in chorus or 

 scattering calls. In the first half of May the maxima 72°-92°, minima 53°-67° 

 obtained. In the last of May maxima of 8o°-97° and minima of 63°-72° 

 obtained. In the first half of June maxima were 83°-9o°, minima 56°-7i°. 

 In the last of June maxima were from 8o°-98°, minima 67°-78°. In the first 

 of July maxima were 85°-92°, minima 67°-74°. In late July maxima were 

 85°-90°, minima 67°-72°. Thus we have minima of 5o°-62°, S3°-67°, 63°-72°, 

 56°-7i°, 67°-78°, 67°-74°, 67°-72°. The later the season of chorus quite 

 Ukely the greater the rain to start it. 



The actual records of air temperatures taken by us in camp in 192 1 when 

 we heard Bitfo terrestris were 58°-88°. Most of the records range from 

 65°-75° and were preceded or accompanied by rain, or cloudy weather. When 

 we first entered the swamp on April 22 and 23 we had considerable rain.
