In connection with the studies of the calcium metabolism in the sea urchin, Hemicentrotus pulcherrimus, the relationships between the body weight and organ weights were observed in the freshly sampled animals of 5 to 22g in body weight. The allometrical equation fitted for relation between body weight and test diameter, but simple equations between body weight and weights of test, lantern, gut, gonad and remainder (mainly coelomic fluid). In the animals (8 to 18g) starved for 49 days, the weights of gut and gonad decreased greatly, but those of lantern and test increased slightly, suggesting that the material, probably including calcium, required for the test formation is supplied from sea water even under starvation.
