In 192 1 and 1922 the prevailing temperatures when we heard the species 

 in chorus frequently were from 'jo°-'jg°. An average of 50 temperatures taken 

 when the species was calling gives 74°. The most common range was from 

 7 1°-76°. The big choruses almost invariably came after a big rain. Then the 

 wet grassy places teemed with Httle Pseudacris ocularis. In 192 1 on May 20 

 we had an immense chorus, they were calling during the day. The tem- 

 peratures were ■jo°--j2° and the activity came after a rain. On June 24 and 

 25 after a rain they were common. Temperatures of 'jo°-'j6°, 72°, 73°, 76° 

 and much higher in mid-day prevailed. On July 15 a strong thunder storm 

 began. On this day and the following day Pseudacris ocularis without end 

 began. Temperatures from 73°, 76° and upward obtained. On July 29 we 

 were caught in a down pour on Black Jack Island, We were encamped in 

 the moist pine barrens. All about strongest chorus of Pseudacros ocidaris we 

 ever heard. Temperature about 73°. 



In 1922 we had similar experiences. Humidity is first needed to send them 

 into breeding. The temperatures most prevalent are from 70° to 79°.
