If only one egg-batch was produced, the gonads of berried females could be expected to be in a resting stage; if, however, more than one batch of eggs was extruded, the gonads could be expected to be in various stages of development. A total of 245 females in berry were dissected and the results are tabulated in Table VII which is graphically expressed in text- figure 7.
