Haeckel says: Upper left- Lateral view. The ventral capsule is visible between the two valves of the inner shell, the galeae of which are filled by the phaeodium. Lower left- Distal end of a style. Upper right- Basal view. Lower right- Dorsal view (somewhat obliquely from the left side). The galeae appear triangular.

Haeckel says: Left- A complete shell. Right- the radiate operculum of the central capsule.

Bigelowiella (big-ell-owe-ee-ell-a) one of the tiny planktonic algae. Two plastids and one flagellum are visible. Differential interference microscopy.

Cyranomonas is a biflagellated colourless protist of unknown affinities. Cells are ovoid, 4.5 - 5 µm long, dorso-ventrally flattened, and somewhat flexible. The anterior part is depressed of concave. Two thickened flagella emerge from the right side of the cell and are not acronematic. The anterior flagellum is about the length of the cell and flickers stiffly forwards. The posterior flagellum inserts to the left of the anterior flagellum, is 1.5 the length of the cell, and trails behind the cell. The nucleus is located anteriorly. The cells contain small food materials. The cells glide slowly with the anterior flagellum. C. australis is currently the only species in the genus, which has so far only been reported from Australia.

Small heterotrophic flagellate of about 15 µm which has four anteriorly directed flagella and bears posterior axopods with extrusomes. Flagella and axopods arise from a centroplast situated on the anterior face of the nucleus. Two free-living species from freshwater habitats which feed on bacteria. Phase contrast.

Paulinella (paul-in-ella) is a testate amoeba but this species is distinguished by the presence of (usually two) curved endosymbiotic blue green algae. The small aperture of the lorica is to the top of the image. Differential interference contrast.
