The double contoured outer membrane exhibits only one opening, with a radiate operculum and long proboscis. The granular protoplasm encloses clear spherical vacuoles. The sphæroidal nucleus contains irregular amœboid nucleoli.Fig. 2.Phæodina tripylea, n. sp.,×3001545A central capsule in self-division, with two elliptical nuclei. The astropyle is already bisected and has two proboscides.Fig. 3.Cannorrhaphis spinulosa, n. sp.,×3001552A complete specimen with two central capsules, each of which contains two nuclei. The alveolate calymma contains a dark phæodium and is surrounded by tangential tubular needles.Fig. 4.Cannorrhaphis spinulosa, n. sp.,×3001552A single tangential tube.Fig. 5.Cannorrhaphis spathillata, n. sp.,×3001552A single tangential tube.Fig. 6.Aulactinium actinastrum, n. sp.,×1001574A complete specimen, seen in optical meridional section. In the centre the spheroidal central capsule, with its double membrane and three openings (above two lateral parapylæ, below the large astropyle with its radiate operculum). The capsule encloses numerous spherical vacuoles and two hemispherical nuclei, each with numerous nucleoli. The anterior half of the capsule is surrounded by the blackish phæodium. The spherical calymma contains numerous globular alveoles and is pierced by the radial tubes, the proximal ends of which are in contact with the surface of the central capsule (compare Pl.103, fig. 1).Fig. 7.Aulactinium actinastrum, n. sp.,×3001574A single radial tube.Fig. 8.Aulactinium actinelium, n. sp.,×2001574A single radial tube.Fig. 9.Mesocena stellata, n. sp.,×6001557A single annular piece of the skeletonFig. 10.Dictyocha stapedia, n. sp.,×3001561A complete specimen, observed living at Ceylon. In the centre is visible the large, spheroidal, tripylean central capsule, with its three openings, containing a large nucleus with numerous nucleoli. Its oral half is covered with the dark phæodium. The voluminous spherical calymma contains numerous globular alveoles and its surface is covered with scattered, stirrup-shaped pieces of the skeleton. Numerous free pseudopodia arise from the surface.Fig. 11.Dictyocha stapedia, n. sp.,×8001561A single piece of the skeleton, from above.Fig. 12.Dictyocha stapedia, n. sp.,×8001561A twin piece of the skeleton.Fig. 13.Dictyocha medusa, n. sp.,×8001560A single piece of the skeleton, from the side.Fig. 14.Dictyocha medusa, n. sp.,×8001560A single piece of the skeleton, from above.Plate 101.

In the centre is visible the red central capsule with its three openings, containing a large nucleus of half the size, with numerous nucleoli. The alveolate calymma encloses a green excentric phæodium, is surrounded by a veil of interwoven tangential needles, and forms conical elevations, which enclose the piercing radial tubes. Between these radiate numerous pseudopodia (compare for the single parts, Pl.103, fig. 1 and Pl.104, figs. 1-3, and their explanation).Figs. 2-6.Auloceros furcosus, n. sp.,×1001583Distal ends of different radial tubes, exhibiting the great variability of this species.Fig. 7.Auloceros trigeminus, n. sp.,×3001584Distal end of a single tube.Fig. 8.Auloceros capreolus, n. sp.,×2001584Distal End of a Single Tube.Figs. 9, 10.Auloceros cervinus, n. sp.,×3001584Distal ends of two single tubes.Fig. 12.Auloceros spathillaster, n. sp.,×3001585Distal end of a single tube.Figs. 11, 13.Auloceros arborescens, n. sp.,×3001585Distal ends of two single tubes.Plate 102.
