Cytoskeletal structure in these vesicomyid erythrocytes was distinctive. Fibers radiated from prominent centro- somes containing centriole pairs similar to those of arcid erythrocytes, but. in contrast to the arcid cells, the vesico- myid erythrocytes contained no MB. So far as we have been able to determine, this kind of organization has not been observed previously in erythrocytes of any other species. Our survey encompasses annelid, brachiopod, echinoderm, echiuran. molluscan. priapulid. and sipuncu- lan representatives among the invertebrates (Table 1). as. mt f^.
