138 Cells globular, four, eight, sixteen or a few more united into little cubes with rounded corners—the parts in contact flattened ; cells of the colony attaining a diameter of .00016 in.; colonies strung together by the partition walls of the cells; again united into larger masses. Cell contents greenish, yellowish or reddishbrown, somewhat polished. In the stomach of healthy and diseased man and higher animals; also sometime occurring in other parts of the body.

S. urinse, Welcker. Synonym: Merismopedia urinoe, Rabh. (Flora Europ. Alg. II, p. 59).

Cells very small, .00004 to .00008 in. in diameter, eight to sixtyfour united in a family; eight united cells .00008 to .00012 in., sixty-four cells .00016 to .00020 in. in diameter. In the bladder.

S . l i t t o r a l i s , Winter. Synonyms: Erythroconis litoralis, Oersted; Merismopedia litoralis, Rabh. (Flora Europ. Alg. II, p. 57).

Cells globular or, when ready to divide, oval; .000012 in., seldom .00008 in. or more in diameter; united in families of four, six, eight, etc., which are again grouped in larger colonies (as many as sixty-four 4-parted cells). Cell contents colorless, but there is in each cell one to four red granules of sulphur. In putrid sea-water.

S . R e i t e n b a c h i i , Winter. Synonym: Merismopedium Reitenbachii, Caspary (Schriften der physikal, okon, Gefellsehaft zu Konigsberg, XV, 1874, p. 104, T. II, Fig. 7 to 15).

Cells globular, or when ready to divide, oval or elliptical, .00006 to .00010 in diameter, dividing ones attaining .00016 in. long; rarely single or in twos or threes, usually four or eight, or more often sixteen or more united. Cell wall colorless, with the forming wall-borders rose-red. On the submerged parts of aquatic plants and dead sticks, and swimming free in fresh water.

The families consist at most of thirty-two cells; those of eight.globular cells measure .00040 in. long, .000175 in. wide; tabular families of eight cells .00026 in. long, and .000175 in. wide, while those of sixteen cells are .00066 long and .00043 wide. Probably also Merismopedia vialacea (Breb.) Kutzing, (Spec. Alg. p. 472, und Tabul. phyc. v. T. 38. Fig. 7; Rabenhorst Flora Europ. Alg. IE, p. 57) belongs to the Fungi. This agrees in its large size nearly with Sarcina Reitenbachii. yet differs on account of the color, especially as not rarely one hundred and twenty-eight cells are united in a family. Very similar, but hitherto perhaps only found in Sweden, is MerismopediU chondroideum, Wittr. (Wittr et Nordstedt, Algae Exsiccata, 200). S. h y a l i n a , Winter, Synonym: Merismopedia

hyalina,Kutz.

Cells globular, almost colorless, .00006 in. in diameter; families mostly of four to twenty-four (rarely more) united cells, attaining .00060 in. in diameter. In swamps.
