Mast cells of lymphoid type containing alcian blue positive granules are present in the thymus, the lymph and blood of fish, as well as in the spleen during winter season. In summer, the number of alcian blue positive mast cells increases in the thymus. The granules of these cells contain serotonin. Endoepithelial formations resembling the calix cells are present in the squamous skin which, in spite of their alcian blue positive reaction, cannot be classified as mast cells. In contradistinction to other vertebrates, neither the number nor the maturation of mast cells is influenced by cortisone treatment.
