ANOURA. PIPAD^. 



enclosed eggs are hatched, and the young tad- 

 poles pass their stage of existence within the 

 cells, from which they do not emerge until 

 they have passed their metamorphosis, and 

 assumed the form of the adult animal, though 

 very small. This takes place in about eighty- 

 two days from the time when the eggs were 

 first placed on the back of the mother. Those 

 cells which occupy the middle part of the back 

 are first evacuated, doubtless because they were 

 first occupied. The mother, relieved of her 

 charge, now resorts to the land, where, it is 

 reported, she frees herself from her honey- 

 combed skin by rubbing her body against a 

 stone.
