Abstract
The histology of the salivary glands of the armadillo Zaedyus pichiy (Desmarest, 1804) was studied. Three pairs of major compound tubuloacinar salivary glands, parotid, submandibular and sublingual, were distinguished. The parotid gland is histologically a serous gland. The submandibular gland consists of two lobes. The anterior lobe is composed of mixed and serous acini. The posterior lobe is predominantly mucous. There is a reservoir or salivary bladder, related with the anterior lobe. The sublingual gland is mixed, composed of mucous acini with scattered serous demilunes
