The corrosion resin-casts and the tissue preparations of the digestive diverticula of the razor-shell, Sinonovacula constricta were observed. The resin-casts were made of the prepolymerization methyl methacrylate (MercoxCL-2R) containing 10 % Mercox MA. The tissue preparations were stained with Azan. The digestive diverticula developed up to 1/4 of the circumference of stomach. The origins of the ducts opened at 2 embayments on the stomach. Internal wall of the duct was uniformly covered with the cilium from the origin to the apex. Each tubule extended at the end of the duct.
