I previuosly thought it was Carchesium, but I am not sure it, now.
So I will be very grateful for the identification.

A very pretty picture. :) Do you have images of the stalks? The shape of the zooid is not sufficient for identification. ID of sessile peritrichs usually begins with the stalk (does it have a myoneme, is the myoneme continuous or broken, is its mode of contraction zigzag or spiral, etc.) If you can see the stalk in vivo, it is usually possible to get down to family level, and often possible to assign your specimen to genus (however to get down to genus level sometimes requires a clear view of other features, such as pellicle, and oral ciliature).

Bruce,

Thank you very much for the immediate answer.
I am enclosing additional image. I hope it will help you in the ID. Unfortunately this image is the only additional one.

Ah, as I suspected. :) No myoneme in stalk, strong peristomial lip, single winding of peristomial membranelles: Epistylis.
