Family Astrosphærida.

PLATE 19. Astrosphærida. Diam. Page. Fig. 1. Drymosphæra polygonalis, n. sp., × 200 [249] Fig. 2. Leptosphæra hexagonalis, n. sp., × 200 [244] Showing the central capsule (forming numerous club-shaped protuberances) and the simple spherical nucleus in its centre. The skeleton is nearly the same as in Diplosphæra hexagonalis (fig. 3). Fig. 3. Diplosphæra hexagonalis, n. sp., × 200 [246] The spherical central capsule, with radially striped protoplasm, is enclosed in the inner shell, and exhibits in its centre the clear spherical nucleus. Fig. 4. Astrosphæra hexagonalis, n. sp., × 300 [250] Fig. 5. Astrosphæra stellata, n. sp., × 300 [251] The central capsule, enclosed in the inner shell, exhibits a distinct radial striation of the protoplasm, and in the centre a clear spherical nucleus. Fig. 6. Haliomma rhodococcus, n. sp. (vel Sethosphæra rhodococcus), × 400 [237] The greater part of the outer shell is removed.

PLATE 20. Liosphærida et Astrosphærida. Diam. Page. Fig. 1. Drymosphæra dendrophora, n. sp., × 300 [249] Fig. 1a. Meridional section through the central capsule.
