Ciliates: Holosticha and ??

Here two ciliates from a lake water.

Nikon Plan Fluor 40x/0.75, DIC, flash

I think it is holosticha:

I do not know about this:

Very nice captures, Rogelio!

Can't help with an ID, but that first one shows a great view of what I think is this ciliate's cytostome. Do you think there about in middle of the ciliate, at the proximal end of the cytostome, that is a food vacuole/gastriole containing the particles that just got "swallowed"?

Very interesting bugs Rogelio. I like the DIC effect you are getting now.

Great colour balance and clarity

Betty,

Thank you for your comments.

Yes, I think that is a vacuole/gastriole containing a particle.

Mitch and Linden,

Thank you for your comments.

Linden, the Nikon plan fluor is not giving me the DIC quality that I want, I think that I found the problem (the condenser DIC prism is not the right one for the objective prism), I will post some images with the Nikon plan fluor 100x/1.3 oil and the right combination of prism. Thank you for your support.
