Two protozoans from Great Salt Lake

The amoeba inhabiting the waters of Great Salt Lake, which has been previously referred to Amoeba Umax (Dujard in) . Named for mv colleague at the University of Utah, Dr. Seville Flowers. Type localtiv, Garfield Beach, Great Salt Lake, Utah. Type figures 1 to 3. Small amoebae, 18 to 40 micra in diameter. Nucleus (n of fig. 2) obscure, appearing of the compact type, finely granular when stained with methylene blue. Nucleus often obscured both by food particles of a similar size and by pink and green algal cells in the cytoplasm, the green ones (a of fig. 1) probably symbiotic. The pink algal cells break down into clusters of angular granules of a bright red color (roffig-3). Dr. Flowers suggests that the intensification of the color nuiy be due to the pH of the cytoplasm.
