shortly after hatching as no trace of it can be seen in the young 

 frogs, presumably of the year, found in the plants. 



As soon as the legs are sufficiently developed and the yolk 

 reduced the frogs struggle about in the egg, and it is evidently 

 by means of this struggle that the egg envelope is finally 

 broken. Alany sets of eggs found between July 19 and July 23. 

 1913, were near the time of hatching, and the eggs in several 

 sets were observed to hatch between July 22 and July 25. The 

 eggs were all at about the same stage of development, and the 

 eggs in the same set hatched within a few hours. 



There was no evidence of any kind of brooding habit. 

 Adult frogs were occasionally found in plants containing egg 

 masses, bu.t by no means as a rule, and in no case in proximity 

 to the eggs.
