In composition of the blood cells, the Japanese common oyster, Gryphea gigas seems to be different from such allied species as Pinctada martensii and Ostrea edulis. The blood of the former consists of a single kind of blood-corpuscle and blood plasma, while in the latter tow, existence of leucocytes or lymphoid cells as well as erythrocytes has been reported previously. Therefore, the authors propose here to call the blood-corpuscle of G. gigas as it is and avoid using the term leucocyte as no erythrocytes type exist in the blood. The materials used for the present study were made available from nursery grounds of the oyster in Shido Bay, Kagawa Prefecture, during the months from June 1959 to January 1960. The blood was collected with a syringe from the heart and the liver (digestive diverticula). In preparing glass slides in a normal procedure, blood specimens were stained by Giemsa's and May-Giemsa's methods. Microscopic observation at 600 to 1, 500 powers have made it possible to classify, according to WINTROBE (1956), the blood under report into five types (Table 1-A to C). Type VI of the blood cell obtained from the liver is apparently the original body from which the other four types are to be developed.
