Gasirophryne carolinensis 



461 



the average 30 seconds. The actual call in most instances occupied 1.5-2 

 seconds. The intervals of another calling frog were from 1-60, only one 

 below seconds, average 29 seconds. A third frog noted by Mr. Harper on 

 June 26 has 79 intervals from 3-59 seconds, average 30 seconds. 



Normally one would not think of Gastrophryne's call as far reaching. 

 Frequently other frogs such as Hylids {Hyla femoralis, Hyla squirella, Acris 

 gnjllus), Scaphiopus or Bufos {Bufo querdcus and Bufo terrestris) may be in 

 chorus in the same place and may break the record or drown its calls. Some 

 of these species interfere with each other or Gasirophryne in other ways. 

 Once in a flooded furrow, July 3, 192 1, we saw two mated pairs of Gasiro- 

 phryne. One we captured but before we could try for the other a {Bufo 

 terrestris) toad had butted the pair and frightened it. To return to its voice. 

 One has to be within 20-60 yards to hear Gastrophryne calls under normal 

 conditions. They usually call from the water with rear parts submerged 

 and only fore feet planted on back or some support. Occasionally they may 

 be amongst the trash on surface. Occasionally they are out of water on the 

 bank or in a grassy tussock. On May 26 we observed numerous males in 

 one ditch. At times they would crawl out of the water and up the vertical 

 banks of the ditch a few inches. The white throat is swelled out Hke the 

 bubble of a toad or spadefoot and the frog becomes vertical or bent backward 

 with the effort. In the interval the frog returns to a position short of vertical, 

 deflates the throat but may pulsate the throat. At times the male has one 

 or two other notes not of the b a a a . . . order. The same is true of Gastro- 

 phryne texense.
