Note that there is a difference in shape between live animals and stained animals. Most ublications usually favor stained animal pictures which might lead to wrong ID. This is a typical example.

Trithigmostoma steinii (ciliate)
Found this nice Cyrtophorida ciliate in a small pond . It eats diatomae. I identified it using silver carbonate impregnation method.

Very nice! The need for live and stained observations is nicely demonstrated. 
Without the fixed specimens, it might be difficult to rule out the synhymeniida.
For the stained ones, did you use the original Fernandez-Galiano protocol, or one of the updated methods? Did you have a culture to work with, or just wild specimens?

I agree Silver staining helped a lot. I strengthens my feeling that drawing which are often based on fixed samples can be misleading.Bruce Taylor wrote:Very nice! The need for live and stained observations is nicely demonstrated.

I used Fernandez Galiano then counted the number of cilia row to differentiate from T. Cucullus
