This image was taken with DIC of ATCC 50194.  Chlamydodontid ciliates, with distinct postoral break or unciliated field in ventral somatic kineties; preoral kinety complete. The cell has a flat ventral surface and an arched dorsal surface. The cytostome is anterio-ventrally situated and is supported by a protrusible basket of nemadesmata. The dorsal surface is unciliated, except subapically near the left margin there is a single kinety consisting of 5-20 ciliated kinetosomes. Three kineties are associated with the oral region: two circumoral kineties and one preoral kinety above the cytostome; the preoral kinety extends obliquely to the left of the ciliate. There are several longitudinal somatic kineties on the ventral surface; those on the right curve around the anterior end while those on the left extend only to the preoral kinety. The central postoral region lacks cilia. The macronucleus is spheroid to ellipsoidal and located near the posterior. Two contractile vacuoles are usually located on the upper right and lower left of the cell. This ciliate glides quickly over surfaces.
