The bladder amebocytes with large ectoplasmic extrusions and the filiform ame- bocytes are phagocytic. The eleocytes contain red spherules of echinochrome (Mac- Munn, 1885; Kuhn and Wallenfels, 1939). a common echinoid pigment which has been demonstrated in the three species of Strongylocentrotus. The colorless spherule amebocytes with spherical inclusions lack phagocytic power and move by extending broad round eruptive (guttata) pseudopodia. The fusiform corpuscles, which are few in number, have no known function. The hyaline hemocyte gives rise to an extracellular clot after disintegrating at the site of an injury. These disinte- grating cells resemble the colorless spherule amebocytes to a considerable degree and, as a result, may have escaped the observations of past investigators because most of their observations were made on fixed and stained material. The eleocytes have no known function, although several have been suggested by various investigators. Griffiths (1892) concluded that they are associated with oxygen transport as did Awerinzew (1911). Cuenot (1891) opposed this assump-.
