Plate 129. Astrolophida, Litholophida, Chiastolida et Astrolonchida.
Diam.
Fig. 1. Actinelius primordialis, n. sp., × 100
The red central capsule, coloured by carmine, contains numerous intensely stained nuclei.
Fig. 2. Litholophus decapristis, n. sp., × 300
The conical central capsule contains numerous nuclei. The calymma exhibits on the distal end of each spine a coronet of myophriscs.
Fig. 3. Chiastolus amphicopium, n. sp., × 150
Sixteen diametral spines pierce the spherical, red coloured capsule. The conical sheets of the calymma bear myophriscs.
Figs. 3a, 3b. Two isolated diametral spines exhibiting the peculiar spiral revolution at their central part, × 300
Fig. 4. Xiphacantha ciliata, n. sp., × 300
The spherical central capsule is coloured red. The yellowish calymma envelops the radial spines completely. The polygonal network of lines, in which the radiating pseudopodia are symmetrically arranged, is partly visible.
Fig. 5. Xiphacantha ciliata, n. sp., × 300
The central part of the skeleton, exhibiting the central junction of the radial spines.
Fig. 6. Acanthometron dolichoscion, n. sp., × 300
Central capsule of a young specimen; in its upper half the peculiar kidney-shaped nucleus is visible, with its invagination; in the lower half some nucleated yellow cells are visible (intracapsular xanthellæ). These and the nucleus are stained by carmine.
Fig. 7. Acanthometron dolichoscion, n. sp., × 300
Cleavage of an isolated nucleus, with four buds.
Fig. 8. Acanthometron dolichoscion, n. sp., × 300
A central capsule with four large budding nuclei; and numerous small spherical nuclei produced by gemmation.
Fig. 9. Acanthonia tetracopa, n. sp., × 400
Central capsule of s young specimen, with a large, irregularly lobate nucleus.
Fig. 10. Acanthonia tetracopa, n. sp., × 400
An isolated nucleus, exhibiting the peculiar invagination, with its circular folds, and the connection with the flatly conical nucleolus.
Fig. 11. Acanthonia tetracopa, n. sp., × 800
Four flagellate spores.
