I'm looking for the the extemely rare V-IM magnification changer for the E800 scope. If you have seen a listing or have one for sale please let me know.
The first ones look like Colpidium...and I agree w/ Litonotus about Frontonia (the trichocysts are very clear, and the mouth is visible in the last two images).
