(Compare Figs. 3 and 5.) With the completion of the nuclear membrane after the last spermatogonial mitosis, the cells no longer belong to the first division of the spermatogenetic cyde, but now contain the ma- tured number of chromosomes and are spermatocytes. In insect material the transformation is not completed until a period ap- parently considerably later. However, I believe this difference is merely in appearance, lying in the fact that the nuclear membrane is reconstructed much earlier in insect cells. At this stage the cells of Scolopendra enter upon a period re- markable for the extraordinary changes which take place in their.
