<jats:p> Distribution of magnesium and strontium was determined between waters and calcites secreted by the oyster species <jats:italic>Crassostrea virginica</jats:italic> and <jats:italic>C. rhizophorae</jats:italic> in natural habitats at eight localities, from Maine to Puerto Rico. The concentration of strontium in the calcite shells increases with increasing temperature in the range 13° to 25°C, and also with increasing Sr <jats:sup>++</jats:sup> /Ca <jats:sup>++</jats:sup> molal ratio in the water. The concentration of magnesium in the shells increases irregularly with temperature, and it is apparently independent of the Mg <jats:sup>++</jats:sup> /Ca <jats:sup>++</jats:sup> ratio in the water. The greater variation with temperature in the distribution factor for magnesium may be related to genetic differences between semi-isolated populations. </jats:p>
