A series of transverse constrictions becomes formed round the body below the mouth, dividing it up into corresponding rings, each of which eventually gives rise to a Medusa known as an Ephyra (fig.

In Myobia, which is parasitic on the common mouse, the ventral plate becomes divided by five constrictions into six segments (fig.

These constrictions are in the position of commissural bands of nervous matter; of these the limiting nervous strands between the thalamencephalon and mesencephalon and between the mesencephalon and the hind-brain are of primary importance.
In constrictions which are firm, but not sensitive, a good plan is to insert a Molesworth elastic tube and gradually distend it by hydrostatic pressure; Barnes's dilators have also been successfully used.
Constrictions occur at fairly regular intervals along the fibre so that, after treatment with cuprammonia, the cotton fibres resemble strings of little beads.
The secondary and inconstant constrictionswhich we find in many #Botryodea#, and which produce a greater number of lobes in the cephalis, require further accurate observation.
