1. The internal features and mechanisms, selection, digesition, absorption to the digestive diverticula and excretion relating to the stomach of Japanese pearl oyster. Pinctada martensii, were investigated. 2. The main structural variations of the stomach between P. martensii investigated in the present study and P. vulgaris described by P1RCHON12), and the common structural features of these species in comparison with the other families of Pseudolamellibranchia were confirmed. 3. A diagrammatic representation of the features and the circulation of food materials in the stomach were given. 4. It was found that the portions on the dorsal roof of the stomach take part in the digestive function of the stomach. And the mechanisms of absorption towards and excretion from the ducts of digestive diverticula became clear by analyzing of the structural features and the ciliary currents in the openings of ducts and embayments.
