Ceratium, Tachysoma & Uroglenopsis

Going through some old and troublesome stacks, I finally took the time to try to sort these out. The Dinoflagellates are difficult to stack as they are very irregular and tend to give a blurry surface structure. The Tachysoma (I think, but not sure about the ID) was moving fiercely, so I had a hard time finding a sequence good enough to stack. I am not 100% sure about the ID on the Uroglena, so please correct me if I am wrong. All taken with a 60X Water Immersion objective.

A fellow forum member at microbhunter.com suggests the the Uroglena in fact is a close relative, Uroglenopsis. There are actually entire research papers on the topic on how to identify the differences between the two species (!). Looking through the paper, I think Uroglenopsis is the correct ID. I have changed the title of this post accordingly.
