Cannosphærida.

Fig. 1. Cannosphæra antarctica, n. sp.,×50[1640]
The entire shell. The inner mammillate shell, from the month of which is prominent the phæodium, in connected by numerous radial beams with the outer shell.
Fig. 2. Cannosphæra antarctica, n. sp.,×200[1640]
The inner shell, from the mouth of which is prominent the phæodium, and a single hexagonal mesh of the outer shell, connected with the former by thin radial threads.
Fig. 3. Cannosphæra antarctica, n. sp.,×200[1640]
A single radial spine, with four terminal branches.
Fig. 4. Cannosphæra pacifica, n. sp.,×200[1641]
The inner shell, exhibiting on its base the widely open mouth, and in its upper half the transparent spherical central capsule with its nucleus. Of the outer shell (which is connected with the inner by thin radial threads), only a few polygonal meshes are visible.
Fig. 5. Cannosphæra atlantica, n. sp.,×200[1640]
The inner shell, connected by spiny radial beams with the outer shell, a quadrant only of which is visible.
Fig. 6. Cannosphæra atlantica, n. sp.,×200[1640]
A single radial spine, with five terminal branches.
