The cellular respiration of fresh-water mussels, Hyriopsis schlegelii and Cristaria plicata, was studied from some comparative aspects of physiological chemistry. The former species, which is used as the mother-mussel in the fresh-water pearl-culture industry, is endemic to the Lake of Biwa, but the latter is a common species in lakes and ponds of Japan. Anato-mically, both of them are very similar to the genera Unio and Anodonta. The experiments were carried out during winter to early spring. The materials used were about 14-17cm. in shell length, and about 4-6 years old. The results obtained are summarized as follows: 1. The gill showed the highest rate of endogenous respiration among various tissues of the mussels (Table 1). 2. The endogenous respiration of the gill was strongly inhibited by cyanide and azide, and the inhibited respiration was recovered by addition of methylene blue (Fig. 1 and Table 2). 3. The respiration of mussel tissues was accelerated by 10-3 M-10-2M of succinate, and this effect was especially remarkable in the heart and the adductor muscle. In the striated portion of the adductor muscle, the effect of succinate was twice as much as in the smooth portion. No accelerating effect was observed with 10-2 M of pyruvate, citrate, α-ketoglutarate and glutamate. 4. Although the endogenous respiration of mussel tissues was not inhibited by malonate, the accelerating effect of succinate was strongly depressed by malonate (Table 3 and Fig. 2).
