In this Plate _Fig._ 1 shows the elegant lattice-sphere of Rhizosphæra; _Fig._ 2 represents Sphærozoum, whose skeleton consists of loose spicules, arranged tangentially; Actinomma, _Fig._ 3, possesses three concentric lattice-spheres, joined by radiating spines; _Figs._ 4, 5, and 6, represent Lithomespilus, Ommatocampe, and Carpocanium; _Fig._ 7 represents a deep-sea form (Challengeria), whose oval case is formed of a regular, very fine-meshed, network; _Fig._ 8 depicts the elegant lattice-sphere of Heliosphæra; _Figs._ 9 and 10, Clathrocyclas and Dictyophimus.
