mode of immature oocytes not represented in the 

 figure. Stage II ovaries contained a mode of 

 oocytes at 0.30-0.35 mm, representing various 

 stages of vitellogenesis, while stage III ovaries 

 included this developing mode and another mode 

 (0.50 mm) nearing hydration. A large amount of 

 variation was noted in the relative frequency of 

 oocytes in the most advanced mode of the stage 

 III ovaries. Similar results were exhibited for 

 size-frequency distributions of uku ovaries con- 

 structed by the cork borer method. This method 

 allowed deUneation of the immature mode as 

 well as the other advanced stages (Fig. 8b).
