Each of these classes of defensive proteids can obviously be further sub-divided into those that act on the mibrobe itself and those that act on the poisons it generates. The sub-classes I propose to denote by adding the prefixes " myco-" and " toxo-

The sperm- cells originate in the ectoderm of the ccenosarc and wander into the ectoderm of the zooids, where they fuse into aggregations to form a spermarium. 6.

The same result might be got, supposing the cilium to be a straight and not a curved extension...
