For comparative purposes the ripest-appearing ovaries from the Hawaiian area (no, B472) 
and the western equatorial Pacific (no. 1002) were also selected for detailed study. The numerous 
eggs smaller than 0.121 mm. were excluded, however, since ovary no. 57 had already provided 
information about this part of the frequency distribution. The smoothed frequency distribution of 
egg diameters of the ovary from the western equatorial Pacific (fig. 2) shows three definite 
groups of maturing eggs at 0.35 mm., 0.51 mm., and 0.98 mm. The ovary from the Hawaiian 
area (fig. 2) shows a definite last mode at 0.66 mm., which is a position below those of the last 
modes of the ovaries of the other two areas, Two more modes of maturing eggs are suggested at 
0.29 mm, and 0,40 mm, The fact that these two suspected modes are at positions slightly to the 
left of comparable but better defined modes in more mature ovaries strengthens the possibility 
that they are real. 
RELATION OF RELATIVE OVARY WEIGHT TO DEGREE OF RIPENESS 
In order to determine more accurately the position of the final mode in the size frequency 
distribution of eggs for all ovaries, systematic measuring of ova representing that mode was 
begun, Whenever the group of largest eggs was not distinguishable from the rest of the eggs by 
its physical characteristics, measuring was started with eggs which were considered small
