In the course of an investigation of the nature of the heart and kidney of D. pilsbryi, the present author discovered an unexpected configuration of the anatomy of the digestive system (Bazata, 1971). The present report represents an extension of this preliminary study and is the first detailed account of the digestive system in D. pilsbryi and D. texasianum. Comparative descriptions of the siphonal complex, the foot, and the histology of the anterior mantle also are given.
