In figs. 9 and 10 of the plate the central body has split up {d. h.) preparatory to the formation of §poi'e-like bodies. In correlation with the small size of the capsules in the male gonophore it may be noticed that there is but little space for development, as the umbrella- Text-fig.

It is interesting to note this adaptation to the environment. In one female gonophore a capsule was found embedded in the ectoderm at the future opening of the umbrella-cavity. It differed from the capsules growing free in the umbrella- cavity in the almost complete absence of the outer compact layer, and in the layers of the capsule being apparently more separable from one another. The real nature of the central bodies and capsules is problematical. The central bodies are, as we have seen, highly refringent, and stain in section only w^ith difficulty. The structures in a young condition can be embedded and cut with a microtome fairly well, but in an older condition, when.
