Summary

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


Plate 90. Androspyrida.
Diam.
Fig. 1. Nephrospyris paradictyum, n. sp. (vel Paradictyum paradoxum), × 250
The complete shell, seen from the frontal side.
Fig. 2. Nephrospyris paradictyum, n. sp., × 250
The incomplete shell, seen from the dorsal side.
Fig. 3. Nephrospyris paradictyum, n. sp., × 500
The sagittal ring, isolated, from the dorsal side; more enlarged.
Fig. 4. Nephrospyris paradictyum, n. sp., × 120
Vertical section through half the shell, exhibiting the thickened margin with the included symbiontes (compare page 1101).
Fig. 5. Nephrospyris paradictyum, n. sp., × 200
Oblique marginal view of the shell.
Fig. 6. Nephrospyris paradictyum, n. sp., × 250
Marginal view of a young specimen, with open fissure between the two parallel net-plates.
Fig. 7. Nephrospyris paradictyum, n. sp., × 250
The soft body alone, without the skeleton. The bilobed central capsule exhibits a central transverse nucleus, and on each lobe a stratum of oil-globules. The kidney-shaped calymma contains on the margin numerous symbiontes (Xanthellæ or Vorticellinæ? Compare page 1102).
Fig. 8. Nephrospyris paradictyum, n. sp., × 500
Three single unicellular symbiontes (Zooxanthellæ?).
Fig. 9. Nephrospyris renilla, n. sp. (vel Nephrodictyum renilla), × 250
The bilobed central capsule is enclosed by the discoidal shell and in the middle constricted by the sagittal ring; it contains a transverse nucleus. The kidney-shaped calymma contains in the peripheral part numerous symbiontes (Xanthellæ or Vorticellinæ? Compare page 1101).
Fig. 10. Nephrospyris renilla, n. sp., × 250
A singular abnormality (occurring not rarely), in which the reduced skeleton has nearly disappeared and the sagittal ring alone remained. The kidney-shaped calymma, however, which encloses numerous symbiontes, has preserved the form of the skeleton. The bilobed central capsule is similar to that in figs. 7 and 9, and is encircled by the thickened sagittal ring.
