*For female lobsters bearing eggs, there can naturally be no molt during the period that the 

 external eggs are carried; this is at least for 11 or 12 months. 



tBecause of the great lack of data on the molting periods of stages 26 to 35 the following 

 estimate must be, to a high degree, speculative. It can not, however, fall far from actual 

 conditions. 



Jit is uncertain at just what time the spring or early summer molt for female lobsters not 

 bearing external eggs is first omitted, but it is probably near this stage.
