SUMMARY: The histology of the salivary glands of the armadilloZaedyus pichiy (Desmarest, 1804) was studied. Three pairs of majorcompound tubuloacinar salivary glands, parotid, submandibular and sublingual,were distinguished. The parotid gland is histologically a serous gland. Thesubmandibular gland consists of two lobes. The anterior lobe is composed of mixedand serous acini. The posterior lobe is predominantly mucous. There is areservoir or salivary bladder, related with the anterior lobe. The sublingualgland is mixed, composed of mucous acini with scattered serous demilunes.
