English: Illustration from Report on the Radiolaria collected by Challenger during the years 1873-1876. Part III. Original description follows: Plate 19. Astrosphærida. Diam. Fig. 1. Drymosphæra polygonalis, n. sp., × 200 Fig. 2. Leptosphæra hexagonalis, n. sp., × 200 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 The spherical central capsule, with radially striped protoplasm, is enclosed

Diplosphæra hexagonalis, n. sp., × 200 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 Fig. 5. Astrosphæra stellata, n. sp., × 300 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 The greater part of the outer shell is removed. . 1887 65 Radiolaria (Challenger) Plate 019
