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.

Sainouron (sigh-noo-ron) is a small gliding flagellate from soils. Body elliptical, one trailing flagellum, rarely with an anterior flagellum. This image shows a subapical insertion of the flagellum. The cell shape is somewhat distorted (swollen). Phase contrast.

Cholamonas (coal-a-moan-ass), cercomonad flagellate described early in the third millenium, with two subapically inserting flagella. Phase contrast micrograph.

Sainouron (sigh-noo-ron) is a small gliding flagellate from soils. Body elliptical, one trailing flagellum, rarely with an anterior flagellum. The flagellum can here be seen to be acronematic (the far end is thinner). 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.
-
Hellkesimastix (hell-keys-ee-ma-stix) a small flagellate, originally reported from soils. With one trailing flagellum and one other short flagellum. Probably,y a cercomonad. Phase contrast micrograph.

Helkesimastix faecicola Woodcock and Lapage, 1915. Cells ovoid or drawn out, 5-10 microns long and about two-thirds as wide as long. A single flagellum, 2-3 times cell length, inserts at or slightly below the cell apex, is attached along the length of the body and also adheres to the substratum as cells glided. The nucleus is central, and there is a single contractile vacuole towards the posterior. Cells are slightly flexible and the cytoplasm is sometimes drawn out along the trailing flagellum.
