Condylostoma cf. magnum Spiegel, 1926
( Figure 7A–C View Figure 7 )
This organism was only found from protargol-impregnated slides and no in vivo data (e.g. concerning the body shape and size) are available. With reference to the infraciliature, it is extremely similar to the well-known species, Condylostoma magnum Spiegel, 1926 , but differs from the latter, however, in having fewer somatic kineties (ca 30 versus 47–56) (Dragesco 1996; Song and Wilbert 1997), which indicates that these two forms might not be conspecific. As a document contribution to studies in the future, a brief description is supplied here.
Description
Cells about 250 M m long after impregnation, no tail present although caudal end might be conspicuously pointed ( Figure 7A View Figure 7 ). Buccal field probably relatively small (about one-sixth of body length after fixation) ( Figure 7C View Figure 7 ). Macronucleus moniliform with ca 10 ellipsoid nodules, lying slightly to right of main body axis ( Figure 7B View Figure 7 ).
Somatic kineties composed of paired basal bodies as in other congeners, both ciliated with relatively short cilia. About 30 somatic kineties, some of which terminate subcaudally.
Adoral zone of membranelles conspicuous, consisting of more than 120 membranelles with proximal portion extending spirally into dominant buccal cavity. Paroral membrane developed, on right of dominant buccal cavity, terminating posteriorly near cytopharynx ( Figure 7C View Figure 7 ). The number of cirri-like membranelles at distal end of adoral zone (at least two) not exactly determined because of the invagination and contraction of related portion ( Figure 7C View Figure 7 , arrowhead).
