Cell ovate, 8±18 Mm long, 6±13 Mm wide, dorso-ventrall y ¯attened, metabolic, but not vigorously so, with a small ingestion organelle. With pellicular striations following a S-helix on both faces of the cell. The dorsal striations are more strongly developed than the ventral ones. This species usually moves by skidding in a counter-clockwise direction. Two ¯agella are similar in length, are slightly longer than the cell and point in diOEerent directions when moving; the anterior ¯agellum points to the right, the posterior ¯agellum to the left. The posterior ¯agellum has a knob at its base within the ¯agellar pocket and is stronger than the anterior ¯agellum. In immotile cells, the ¯agella coil up. The reservoir and nucleus are in the left side of the cell. Common.

Cell outline elongate ovate, 20 Mm long and about 8±11 Mm wide, ¯attened, with squirming movement and with pellicular striations following a S-helix. Two emergent ¯agella are similar in width. The anterior ¯agellum is approximately 2±2.5 times the length of the cell and is longer than the posterior ¯agellum which is slightly longer than the cell. The ingestion organelle may be di cult to see. The reservoir is in the left ventral side of the cell and the nucleus is in the posterior part of the cell. Refractile bodies lie under the cell surface. Cells move by gliding. Rarely observed.
