Figs 30-37. Cyrtophymena marina from life (30-35) and after protargol impregnation (36, 37). 30 - ventral view of a typical individual;
31 - lateral view of two specimens, to show the difference in cell thickness; 32 - dorsal view, to show the sparsely distributed cortical granules;
33 - ventral view (redrawn after Kahl, 1932); 34 - ventral view of a well-fed cell; 35 - ventral view of a slender form, to show the distribution
of crystals (see also the inset); 36, 37 - ventral and dorsal views of infraciliature. BC - buccal cirrus, CV - contractile vacuole, DK4 - dorsal
kinety No. 4, EM - endoral membrane, Ma - macronuclei, Mi - micronuclei, MVR - midventral rows, PM - paroral membrane, TC - transverse
cirri, VC - ventral cirri. Scale bar - 50 µm
(21-27 vs. 26-37) and frontoterminal cirri (2-4 vs. 4-7),
and lacks ventral rows of cirri (vs. present in
B. amagalievi).

and Wicklow 1983 (Figs 9-20, 38-45; Table 2)
Syn. Keronopsis flavicans Kahl, 1932
To the best of the authors’ knowledge, this species
has never been reinvestigated using modern methods
since it was described by Kahl (1932), who called it
Keronopsis flavicans. Based on examinations of the
