Summary The fine structure of cells involved in phagocytosis in the chiton, Liolophurn gaimardi , is described. These cells were examined in preparations from the gil, foot (expecially the neuropedal connective tissue) and the haemolymph. Both fixed phagocytic cells and circulating haemocytes concentrated labels such as colloidal gold, ferritin, carbon and bacteria within intracytoplasmic vacuoles. The fixed phagocytic cells with their long cytoplasmic processes, vesicles, rough endoplasmic reticulum and close association with collagen‐like fibrils resembled fibroblasts. The haemocites often showed parallel arrays of rough endoplasmic reticulum and proeminent deposits of glycogen‐like particles. They also appeared to be a multifunctional single cell type. possible relationships between the fixed phacocytic cells and curculating haemocites are considered in Discussion.
