  • In Huxley's system (1877), a superordinal division including the Polychœta, Oligochœta, Hirudinea, and Gephyrea, with the Myzostomata doubtfully added thereto: a group the members of which resemble one another generally in the segmentation of the body indicated at least by the serially multiganglionate nervous centers (wanting in most Gephyrea), in the presence of cilia and segmental organs, and in the nature of the larvæ, which are set free when the embryos hatch.
