Ferritin, in both crystalline and paracrystalline forms, occurs in the columnar epithelial cells of the dorsal wall of the radula of the marine chiton Cryptochiton stelleri, order, Polyplacophora.

CYCLIC VARIATIONS IN THE DIGESTIVE GLAND AND GLANDULAR OVIDUCT OF CHITONS (MOLLUSCA).

In Cryptochiton stelleri (Polyplacophora), variation in the size of the glandular oviduct parallels the cyclic variation in the size of the gonad. In Katharina tunicata the digestive gland reaches its maximum size in the fall then decreases to a minimum size in the spring when the gonad is at its maximum size. These variations are not due to changes in the water content of the glandular oviduct and digestive gland.
