English: Illustration from Report on the Radiolaria collected by Challenger during the years 1873-1876. Part III. Original description follows: Plate 11. Astrosphærida. Diam. Fig. 1. Lychnosphæra regina, n. sp., × 200 The entire shell and the central capsule. Numerous club-shaped radial apophyses or cœcal sacs arise from the pink central capsule and are protruded through the pores of the medullary shell, which is completely hidden by them.

English: Illustration from Report on the Radiolaria collected by Challenger during the years 1873-1876. Part III. Original description follows: Plate 11. Astrosphærida. Diam. Fig. 1. Lychnosphæra regina, n. sp., × 200 The entire shell and the central capsule. Numerous club-shaped radial apophyses or cœcal sacs arise from the pink central capsule and are protruded through the pores of the medullary shell, which is completely hidden by them. The sarcomatrix in the calymma, surrounding the central capsule, exhibits a fine radial striation. Numerous retracted pseudopodia, bearing red granules, arise from the sarcomatrix and pierce the calymma radially. The interval between the two concentric shells is filled up by the hyaline calymma. Fig. 2. Lychnosphæra regina, n. sp., × 400 A part of the cortical shell, with a radial spine. Fig. 3. Lychnosphæra regina, n. sp., × 400 The medullary shell and the basal parts of the radial spines arising from it. Fig. 4. Lychnosphæra regina, n. sp., × 400 Distal end of a radial spine. Fig. 5. Rhizoplegma lychnosphæra, n. sp., × 200 The central capsule and the enclosed parts of the skeleton. The protoplasm is radially striped. The central nucleus (red) sends out numerous radial apophyses, which are protruded through the pores of the medullary shell. . 1887 65 Radiolaria (Challenger) Plate 011
