Notes to Table I 



Where a blank is left in the column headed "oviposition'' it indicates that the cocoon was found 

 ■when the mother was captured, the day of oviposition therefore unknown; where a blank is left in the 

 column "Time to hatching" it signifies either that this was not determined, or else that the eggs did not 

 hatch; where a blank occurs in the column "unhatched eggs'' it signifies that these were not counted, 

 while a blank in the remaining columns indicates that the eggs did not hatch. Certain cocoons need 

 further explanation, as follows: 



2002K. Made September 18, too late to I e entered into this table; it did not hatch. 



2003A. Proportion of the sexes not given because many escaped at hatching. 



20I2A. A wild cocoon the mother of which was not secured. 



2013K. Eggs killed by mold, the only such accident. 

 oi6A,B. Cocoons hatched when found, perhaps made the preceding season. 



2016C. Found April 6 and hatched April 17, but the bottle of young dried up so that they could 

 not be counted. 



2017. Other cocoons of this spider were used for the egg series. 



2020A. A wild cocoon that proved to be parasitized. 



202 1 A. A wild cocoon found empty. 



2023, 2030. Other cocoons of these spiders were used for the egg series. 



In the succeeding table these data are so summarized as 

 to bring out the reproductive differences of the several spiders 

 entered in the previous table, the "totals" of the third and seventh 

 columns being averages.
