Abstract

1. The digestive gland of Helix pomatia contains large amounts of calcium and magnesium, 290–1257 and 213–636 m-moles/kg dry weight respectively. These are located in spherules in the “calcium cells”. 2. There is a positive correlation between the concentrations of calcium and magnesium in H. pomatia to which data on Helix aspersa, Cepaea nemoralis and Limax maximus also conform. 3. Separated spherules from H. pomatia contained calcium, magnesium, phosphate and carbonate in the average molar proportions of 1 : 0·6 : 1 : 0·1. X-ray diffraction analysis revealed the presence of calcite. 4. Evidence was obtained for seasonal variation in the amounts of calcium and magnesium in the digestive glands of H. pomatia, but none for the mobilization of these elements during shell repair.
