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 1. Thalassicollida.
Diam.
Fig. 1. Actissa princeps, n. sp., × 300
The entire living Spumellarium. c, The spherical central capsule containing finely granulated protoplasm, which is radially striated in the cortical zone; v, spherical vacuoles enclosed by the protoplasm; n, the spherical nucleus in the centre; l, the concentric nucleolus; f, the radial pseudopodia which pierce the calymma or the (yellowish) jelly-envelope of the central capsule and arise from the granular sarcomatrix.
Fig. 1a. Half of the central capsule of another specimen, in which the original central nucleus is cleft into numerous small nuclei, × 400
Fig. 1b. Half of the central capsule of another specimen, filled up by flagellate spores, × 400
Fig. 1c. Eight isolated flagellate spores, × 800
Fig. 2. Thalassolampe maxima, n. sp., × 8
The entire living Spumellarium. c, The big spherical central capsule; a, the large alveoles filling the central capsule and surrounding a central nucleus; f, the pseudopodia piercing the extracapsular calymma.
Fig. 2a. The nucleus alone, with numerous nucleoli, × 30
Fig. 3. Thalassopila cladococcus, n. sp., × 20
c, The big central capsule; a, numerous large alveoles contained in the central capsule; k, oil globules, many of which are placed in the radially striped cortical zone; the nucleus placed centrally, is covered with numerous radial apophyses or cæcal sacs. f, The radially striped calymma.
Fig. 4. Thalassicolla maculata, n. sp., × 100
c, The central capsule; v, vacuoles filling this capsule; n, the central nucleus; l, the concentric nucleolus; g, the voluminous calymma, a small radial piece of which is only represented; a, the large alveoles; b, peculiar exoplasmatic bodies; p, black pigment in the inner zone; f, the retracted pseudopodia in the outer zone.
Fig. 4a. An exoplasmatic body, × 300
Fig. 4b, Vacuoles in the endoplasm, × 300
Fig. 5. Thalassicolla melacapsa, n. sp., × 300
n, The large nucleus; l, numerous small nucleoli inside the nucleus; v, the vacuoles filling up the central capsule and separated by black pigment; a, large alveoles in the calymma; k, oil globules; b, exoplasmatic bodies; f, the retracted pseudopodia in the outer zone of the calymma.
Fig. 5a. An endoplasmatic vacuole, resembling a cell, × 600
Fig. 5b. A piece of the central capsule, × 600
