1. In the maturation of the eggs of parasitic copepods the behavior of the chromosomes in regard to the question of reduction is very similar to the same process in the free living copepods, yet I differ from Haecker as to the reducing division, considering the first maturation division most probably to be the reducing division. 2. In the spermatogenesis only a small proportion of the spermatids become spermatozoa. Many spermatids degenerate, others become metamorphosed into peculiar nutritive cells. The protoplasm of the nutritive cells degenerates leaving only a sphere of deutoplasm "Austreibekörperchen," which C. Heider ('79) thought was a glandular secretion.
