The archaeogastropodan kidneys were studied by histological, histochemical, and electron microscopical techniques and by physiological injections. 2 different organisation clusters are observed in Archaeogastropoda, but the kidneys are always asymmetrical. The 2 kidneys of Patelloidea and Fissurellidae have the same histological structure. The epithelial cells are inconstantly ciliated and involve many small vacuoles with refringent concretions containing chromolipoids, melanins and ferriciron. The right kidney of Haliotidae and Trochidae have similar histological organization. The lamellae of their left kidney present a papillar shape. The generally ciliated epithelial cells are little, involve many lysosomes and send thick prolongations in the connective tissue. The cells play a role in athrocytose and perhaps in organic resorption. The connective tissue is abundant and peripherically is composed of lipoprotein bundles. These formations could constitute reserves passively deposited by the blood.
