SUMMARY: The histology of the salivary glands of the armadillo Dasypus hybridus (Desmarest, 1804), was studied. Two pairs of salivary glands, parotid and submaxillary, and a salivary bladder are distinguished. Parotids are located anteriorly to the submaxillary glands. They are purely serous glands and excretory intralobular ducts, intercalated and particularly striated ones, are very numerous. Submaxillary glands are of greater size. They possess two lobes, which differs in their histology and histochemistry. The anterior lobe is mixed and the presence of numerous intralobular excretory ducts is remarkable. The bigger posterior lobe is mucous. Intralobular excretory ducts are observed, but they are not as abundant as in the anterior portion.
