The Frontonia are breathtaking!

As for the "bell animalcules," the pellicle has a slight pebbly appearance (see the specimen on the far right), so these are probably Pseudovorticella.

To differentiate the genus from Vorticella with confidence, focus on the pellicle and magnify as much as possible. Pseudovorticella has a netlike silverline system -- often resembling a brick wall; whereas, Vorticella has simple horizontal striations. In some cases (as in Pseudovorticella monilata) the "bricks" are so well defined that they look like little beads, easily visible at low magnification. In other cases (as in Pseudovorticella elongata) the reticulate patterns are very faint, and you have to work hard to detect them!

Thank you your comments.

Bruce, I do not have images of the pellicle; but then the second one on the following link is Pseudovorticella?:

Yes, the second photo in that link clearly shows a Pseudovorticella (in telotroch phase).

Thank you all for your comments!

Here a couple more images of Frontonia that show details of the mouth and WEV (water expulsion vacuole):

Wow

Those last images are unbelievable. Is the first close up with the 20x or 40x objective?
