It occtivrcd as ii sort of floating scum, or else diffused through the water, which was tlien opacpie and greenish. It resembled so a protococcus in gross appearance that I did not think of its being an oscilhi- toria until I placed it under the microscope. The filaments arc almost colorless, and, in most instances, arc very distinctly granulate aiul articulate. The dissepi- ments arc in such cases clear and transparent, perfectly free from granules. This form is very close to the descriptions of the European 0. chlortiui, Ktz., but diflbrs somewhat from descriptions, chiefly in habit of growth. Thq filaments, when in mass, are often seen to be ciu'ved under the res
