The membranous bulge lingual to the mandibular molar tooth was examined microscopically in 12 cats and found to contain a small mixed salivary gland. Approximate size of the gland was 1.0-1.5 mm bucco-lingually, 3.0-3.5 mm mesio-distally and 3.0 mm of depth at the largest part. This gland is a tubuloacinar gland with multiple small openings through several short ducts to the surface of the lingual membrane. Mucous acini were predominant with a few serous demilunes.
