    • Abstract

       

      The magnetic anisotropy of the shells ofPlacuna placenta, Pinna bicolor, Meretrix casta, Vulsella rugosa, Mactra sp., andTurbinella perium, have been determined. In all cases, the crystalline character of the elements as well as their regularity of arrangement have been established and the probable orientations deduced. In the case ofPlacuna placenta information regarding the character andhabit of the crystalline elements has been obtained.
