PLATE 5.Collosphærida.Diam.Page.Fig. 1.Trypanosphæra transformata, n. sp.,×150111A living colony. The centre of the spherical cœnobium contains a large alveole, surrounded by a net of sarcode. The entire calymma is filled up by smaller, thin-walled alveoles. Its inner part contains numerous small, young, central capsules (each with an oil-globule) without shells; in the cortical zone of the calymma lie larger capsules, each of which is enclosed by a fenestrated shell with from two to four or more dentated tubes. Between the radiant pseudopodia very numerous small yellow cells (xanthellæ), which are scattered everywhere.Fig. 2.Trypanosphæra transformata, n. sp.,×300111A single shell.Fig. 3.Trypanosphæra coronata, n. sp.,×300110Fig. 4.Trypanosphæra trepanata, n. sp.,×300110Fig. 5.Odontosphæra monodon, n. sp.,×300102Fig. 6.Odontosphæra cyrtodon, n. sp.,×300102Fig. 7.Acrosphæra inflata, n. sp.,×300101Fig. 8.Mazosphæra hippotis, n. sp.,×400108Fig. 9.Mazosphæra lagotis, n. sp.,×300108Fig. 10.Pharyngosphæra stomodæa, n. sp.,×40098Fig. 11.Buccinosphæra invaginata. n. sp.,×50099Each shell contains numerous larger and smaller crystals.Fig. 12.Tribonosphæra centripetalis, n. sp.,×50098Each shell contains numerous large crystals.Fig. 13.Collosphæra polygona, n. sp.,×20096Plate 5.

PLATE 6.Collosphærida.Diam.Page.Fig. 1. Siphonosphæra socialis, n. sp.,×500106A small piece of the surface of a living cœnobium, seen from the surface. Only four individuals are visible, the central capsule of which contains numerous small nuclei and a central oil-globule. The including spherical lattice-shell is provided with a few (one to four) larger apertures, which are prolonged into short cylindrical tubules. Through these latter radiate bundles of fine pseudopodia, branching and anastomosing, and forming a fine sarcode network between the alveoles of the calymma. On the surface of the alveolated jelly-sphere the pseudopodia form a dense radiating zone. Xanthella or yellow cells are everywhere scattered.Fig. 2.Siphonosphæra socialis, n. sp.,×300106A small cœnobium or colony in the state of alveolation, forming a jelly-sphere, composed of a great number of capsulated individuals, densely aggregated. Each central capsule contains an oil-globule, and is enclosed by a spherical lattice-shell, which bears a few (one to four) short cylindrical tubules. Each shell is again enveloped by a membranous polyhedral alveole and separated from it by structureless jelly. The thick cortical jelly-envelope, which surrounds the whole spherical colony, exhibits a fine radial striation, produced by radiating pseudopodia; many xanthellæ or yellow cells are scattered in the calymma.Fig. 3.Siphonosphæra pipetta, n. sp.,×300108Fig. 4.Siphonosphæra tubulosa, J. Müller,×300105The central capsule, enclosed in the cavity of the shell, has a central oil-globule, and is surrounded by a few xanthella.Fig. 5.Siphonosphæra chonophora, n. sp.,×300107Fig. 6.Siphonosphæra serpula, n. sp.,×300107Fig. 7.Siphonosphæra patinaria, n sp.,×300105The central capsule, enclosed in the cavity of the shell, contains a central oil-globule, and is surrounded by a few xanthella.Fig. 8.Siphonosphæra patinaria, n. sp.,×300105Fig. 9.Siphonosphæra conifera, n. sp.,×300106Fig. 10.Siphonosphæra cyathina, n. sp.,×300105Plate 6.
