postlarvae in the same manner as the Stage I 

 zoeae obtained in the laboratory. 



To verify the validity of the sequence of the 

 larval stages obtained from flasks, larvae of each 

 stage were obtained from plankton and reared in 

 flasks in the same manner for one molt. They were 



then removed from the flasks along with their cast 

 skins, preserved, and replaced with a larva of the 

 same stage. Thus, a Stage II zoea that had molted 

 to Stage III in a flask was replaced with a Stage III 

 zoea from plankton, the Stage III zoea being re- 

 placed in like manner when it had molted to Stage
