Bufo quercicus 117 



throat region. The tip of the sac when not really inflated comes close to the 

 tip of the chin. Otherwise it appears as a little loose vibrating sac 1/2 inch 

 out from the lower part of the throat. When deflated the body inflates. When 

 body is compressed or deflated the sac inflates. 



Its call may carry 1/8 of a mile or more. When this species is in chorus it 

 is one of the most deafening ear deadeners I have encountered when in their 

 midst. We often employed the method of varying the closure of our ears to 

 pick out various notes and cut out other dominant notes. For example, Mr. 

 Harper's note of a chorus 8:30 — 10:00 P. M., July 16 illustrates it "Bufo 

 quercicus, abundant calling. All {Hyla gratiosa, Chorophilus, Hylafemoralis, 

 Bufo quercicus) combined, enough to cave in our ear drums. By half closing 

 ears we shut out the sound of Hylafemoralis almost entirely, and hear others, 

 better than ever especially Chorophilus, Bufo quercicus, Acris, — ".
