The first signs of formation of the posterior serous lingual glands (von Ebner’s glands) were observed at day 22 of prenatal development of the rabbit. The development of glands was initiated by the appearance of epithelial bands, growing into the connective tissue. At day 26 p.c. the epithelial bands were longer. At day 1 of postnatal life the secretory parts of glands were formed together with excretory parts. Carbohydrates were found in the lumen of the excretory parts. At day 15 p.p. it was shown that the excretory parts opened at the bottom of furrows of foliate and circumvallate papillae. In the successive periods of life in the rabbit were observed linear arrangement for excretory parts opening at the bottom of furrows of foliate papillae. Excretory parts which opened at the bottom of circumvallate papillae formed a circular system.
