FURTHER NOTES ON THE SALIENTIA 

 OF JACKSONVILLE, FLA. 



Engy stoma carolinense, Holbrook, the " Nar- 

 row-mouth Toad," is a common Batrachian here, 

 but owing to its nocturnal habits, it is not often 

 seen. After thunder-showers, however, every pool 

 and ditch resounds with its cry, which sounds like 

 a nasal 'baa" or "bee" and has also some resem- 

 blance to the noise made by an electric buzzer. 

 I have caught hundreds of these queer little toads, 

 and on August 28, 1911, came across their spawn 

 in a ditch between two potato hills. The eggs are 

 laid in oblong, jelly-like sheets, or flat masses, 

 about 1J inch long and 1 inch wide. The egg- 

 masses contain about 100 to 150 eggs. 



Below is what I believe to be the first record 

 of the growth and metamorphosis of this species :
