1. 1.

    A conduction system in Stomphia transfers information across the mesogloea from ectodermal receptors to endodermal effectors.

  2. 2.

    In the column, this transmesogloeal system has numerous and widespread connexions.

  3. 3.

    It is suggested that the connexions may be processes from multipolar nerve cells located in the endoderm.

  4. 4.

    Certain aspects of behaviour are controlled by this conduction system which provides yet another pathway to co-ordinate electrical activity.
