The blood of Perophora viridis is found to contain six types of cells: (1) Green cells, which have green‐colored fatty bodies embedded in clear cytoplasm. (2) Orange cells, with orange‐colored bodies of unknown composition in the cytoplasm. (3) Colorless berry‐like cells, with fluid‐filled vesicles in the cytoplasm. (4) Granular amoeboid cells. (5) Compartmental amoeboid cells, which have box‐like vacuoles containing brownian granules of a fatty substance. (6) Vesicular, signet‐ring type of cell having a single large vacuole. The cytological structure of these cells and their reaction to various dyes are described. An effort has been made to homologize the types of cells found in the blood of other ascidians with those found in Perophora. It is concluded that the variety of colors found in the cells of ascidian blood is due to the varying chemical states of the vanadium‐containing chromogen present in the cells.
