Gymnophrys (jim-noff-riss), small amoeboid cell of uncertain affinities. With fine granular pseudopodia extending from the cell which often adopts a spindle shape. There are two very short flagella, but they cannot be seen with the light microscope. Two cells. Phase contrast.
-
Rosculus (ross-cue-lus) a naked lobose amoeba, typically progressing with a single pseudopodium (i.e. is monopodial) hyaline cap is well developed. Nucleus to rear left, contractile vacuole at posterior. Phase contrast.

Bodomorpha (bow-dough-more-fa) is a small cercomonad flagellate, virtually indistinguishable from Heteromita, although said to ingest food with pseudopodia formed posteriorly. With two flagella inserting subapically. Mostly from freshwater and soil. Phase contrast micrograph.
-
Heteromita (het-err-o-might-a), one of the smaller gliding flagellates, mostly from soils and freshwater habitats. Flattened, two unthickened flagella inserting into a subapical depression in the cell. Anterior flagellum beats with a flopping motion, posterior flagellum drags behind. A cercomonad. There can be considerable variation among cells in a population. Phase contrast.
-
Bigelowiella (big-ell-owe-ee-ell-a) one of the tiny planktonic algae. Two plastids and one flagellum are visible. Differential interference microscopy.

Cercomonas (sir-ko-moan-ass), gliding flagellates, two flagella insert just below the anterior apex of the cell. The anterior flagellum beats floppily, the posterior flagellum trails against the substrate. Body very flexible and elements may be drawn out as strands behind the moving cells. Common. Lots of species, but the taxonomy is very unstable. Phase contrast.

Bodomorpha minima Hollande, 1942. Cells are oval or globular in shape, 4-5 microns long, 3-4 microns wide. Not metabolic. As in Bodo, it has a small rostrum in the anterior end, behind which two flagella insert. The posterior flagellum trails posteriorly, while the active flagellum bends slightly ventrally.

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

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.

Haeckel says: Left- Distal part of a single radial tube, with the terminal corona. Right- apex of a six-sided pyramid, seen from the inside.

Cercomonas (sir-ko-moan-ass), gliding flagellates, two flagella insert just below the anterior apex of the cell. The anterior flagellum beats floppily, the posterior flagellum trails against the substrate. Body very flexible and elements may be drawn out as strands behind the moving cells. Common. Lots of species, but the taxonomy is very unstable. This is a compressed cell surrounded by some bacteria. The light circle with the dark centre is the nucleus with central nucleolus, and the very light region is the contractile vacuole. Phase contrast.

Gymnophrys (jim-noff-riss), small amoeboid cell of uncertain affinities. With fine granular pseudopodia extending from the cell which often adopts a spindle shape. There are two very short flagella, but they cannot be seen with the light microscope. Cysts. Phase contrast.

Rosculus (ross-cue-lus) a naked lobose amoeba, typically progressing with a single pseudopodium (i.e. is monopodial) hyaline cap is well developed. Group of cells. Phase contrast.

Cryothecomonas (cry-oh-theek-oh-moan-ass) is a medium-sized heterotrophic flagellate with two similar flagella emerging from a point just behind the apex of the cell. The ventral surface is grooved (and this causes a slight indentation at the front of the cell). Pseudopodia may arise from the ventral groove. They consume diatoms and other detritus. DIfferential interference microscopy.

Heteromita (het-err-o-might-a), one of the smaller gliding flagellates, mostly from soils and freshwater habitats. Flattened, two unthickened flagella inserting into a subapical depression in the cell. Anterior flagellum beats with a flopping motion, posterior flagellum drags behind. A cercomonad. There can be considerable variation among cells in a population. Phase contrast.

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.

Haeckel says: Half the shell, with the enclosed central capsule and the phaeodium, stained by carmine. (The central nucleus dark).
