Where each Polypus is adherent in .a corneous or calcareous cell with thin parietes and only communicates with the others by an extremely tenuous external tunic or by the minute pores which traverse the parietes of the cells. These Polypi bear a general resemblance to the Hydrre. CELLULARIA, Lin. Where these cells are so arranged as to form branching stems in the manner of the Sertularire, but without a tube of communication in the axis. Their substance also is more calcareous.
