Wow, really nice! Smile You've done a wonderful job of showing all 18 cirri in the "oxytrichid" pattern, in that first image.

I think it's reasonable to place this guy in the O. fallax species complex.

The group of three postoral ventral cirri (just posterior of the mouth) is pretty tight, whereas in Sterkiella (the other candidate genus, here) the posterior one tends to be isolated. Also, the transverse cirri (the big ones at the posterior of the cell) don't protrude beyond the margins, and the caudal cirri are too short to see (in these pics, anyway). We can't tell from the pics how flexible the critters are, unfortunately. Even so, Oxytricha seems likely, to me.
