The granular duct cells in the submandibular glands of house shrew (Suncus murinus riukivanus) and dsinezumi shrew (Crocidura dsinezumi) were studied by light and electron microscope. Their ducts showed similar structures and were better developed in the male than in the female of both animals. The myoepithelia associated with the duct cells showed a characteristic distribution, that is, they were ranged not only as proximal granular duct segment but also as distal striated duct segment. Various sized secretory granules in the duct cells of both animals contained neutral glyco-proteins in histochemistry and those of dsinezumi shrew showed more dense matrix than those of house shrew in ultrastructure. Characteristic myelin-like bodies were also contained in the granular duct cells of both animals. It was suggested that they were derived with granular endoplasmic reticulum and successively formed to be discharged into the lumen of the granular ducts as a component of saliva.
