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 (XanthellæorVorticellinæ? Compare page1102).Fig. 8.Nephrospyris paradictyum, n. sp.,×5001102Three single unicellular symbiontes (Zooxanthellæ?).Fig. 9.Nephrospyris renilla, n. sp. (velNephrodictyum renilla),×2501101The 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 (XanthellæorVorticellinæ? Compare page1101).Fig. 10.Nephrospyris renilla, n. sp.,×2501101A 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.Plate 90.
