Killifishes were collected from Patuxent River Estuary and injected intravascularly with colloidal carbon. The ovaries and thyroid gill area were removed and prepared for histological examination. Carbon was not observed within developing oocytes during any of the ovarian cycles. However, particle uptake did occur in follicular and stromal macrophages and in mixed macrophages of corpora lutea in the spent and spawning ovary. Carbon was also observed in endothelial cells of thyroid capillaries, but only during spawning stages. The origin of ovarian macrophages was discussed and corpora luteal capillary morphology was viewed in light of recent permeability studies.
