 of the species. Mr. Lorrilliere writes, "Last night 

 about seven o'clock, while casting for bass, I heard a 

 single clear note, soon followed by several more. The 

 man rowing me about said it was produced by a little 

 green frog, which hung on the leaves of docks, etc., 

 and that it had a little bag under its throat which 

 appeared to collapse when it made its call. The only 

 sound that appears like this call is a twang on a 

 stretched rubber, which is quieted before it has vi- 

 brated more than a second. It can be heard a quarter 

 of a mile or more on a still night."
