Guessing its Trinema Amoeba based on shell pattern. Reichert Zetopan DIK, 60x Nikon Plan Apo 0.95. 6 image stack.

A very nice look at the scales – you can even see the serrated edges of the ones around the mouth. Those I think confirm it as a Euglypha. In Trinema and its family the opening has some modified scales but is characteristically on the side rather than the end of the shell.

Thanks for the ID! I find these in our cooling tower at the plant I work at. I've been told the water used to fill the cooling tower is unusually high in silica at about 60 parts per million. I am guessing thats why testate amoeba are so abundant in the samples.
