The soft body alone, without the skeleton. The bilobed

and on each lobe a stratum of oil-globules. The
kidney-shaped calymma contains on the margin numerous
symbiontes (_Xanthellæ_ or _Vorticellinæ_? Compare page

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 1101
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.
