Replicas of the etched surfaces of the brachial valves of Gryphus stearnsi (Dall and Pilsbry) and Pictothyris picta (Dillwyn) were examined by electron microscopy. This method clearly reveals the crystalline texture of two of the morphologic layers of the shells and demonstrates that the calcite crystals accommodate the tubular punctate structures. These findings may be useful in resolving some of the problems of brachiopod taxonomy.
