English: Illustration from Report on the Radiolaria collected by H.M.S. Challenger during the years 1873-1876. Part III. Original description follows:


Plate 101. Phæodinida, Cannorrhaphida et Aulacanthida.
Diam.
Fig. 1. Phæocolla primordialis, n. sp., × 300
Central capsule, isolated. The double contoured outer mmbrane exhibits only one opening, with a radiate operculum and long proboscis. The granular protoplasm encloses clear spherical vacuoles. The sphæroidal nucleus contains irregular amœboid nucleoli.
Fig. 2. Phæodina tripylea, n. sp., × 300
A central capsule in self-division, with two elliptical nuclei. The astropyle is already bisected and has two proboscides.
Fig. 3. Cannorrhaphis spinulosa, n. sp., × 300
A complete specimen with two central capsules, each of which contains two nuclei. The alveolate calymma contains a dark phæodium and is surrounded by tangential tubular needles.
Fig. 4. Cannorrhaphis spinulosa, n. sp., × 300
A single tangential tube.
Fig. 5. Cannorrhaphis spathillata, n. sp., × 300
A single tangential tube.
Fig. 6. Aulactinium actinastrum, n. sp., × 100
A complete specimen, seen in optical meridional section. In the centre the spheroidal central capsule, with its double membrane and three openings (above two lateral parapylæ, below the large astropyle with its radiate operculum). The capsule encloses numerous spherical vacuoles and two hemispherical nuclei, each with numerous nucleoli. The anterior half of the capsule is surrounded by the blackish phæodium. The spherical calymma contains numerous globular alveoles and is pierced by the radial tubes, the proximal ends of which are in contact with the surface of the central capsule (compare Pl. 103, fig. 1).
Fig. 7. Aulactinium actinastrum, n. sp., × 300
A single radial tube.
Fig. 8. Aulactinium actinelium, n. sp., × 200
A single radial tube.
Fig. 9. Mesocena stellata, n. sp., × 600
A single annular piece of the skeleton
Fig. 10. Dictyocha stapedia, n. sp., × 300
A complete specimen, observed living at Ceylon. In the centre is visible the large, spheroidal, tripylean central capsule, with its three openings, containing a large nucleus with numerous nucleoli. Its oral half is covered with the dark phæodium. The voluminous spherical calymma contains numerous globular alveoles and its surface is covered with scattered, stirrup-shaped pieces of the skeleton. Numerous free pseudopodia arise from the surface.
Fig. 11. Dictyocha stapedia, n. sp., × 800
A single piece of the skeleton, from above.
Fig. 12. Dictyocha stapedia, n. sp., × 800
A twin piece of the skeleton.
Fig. 13. Dictyocha medusa, n. sp., × 800
A single piece of the skeleton, from the side.
Fig. 14. Dictyocha medusa, n. sp., × 800
A single piece of the skeleton, from above.
