    [From the Proceedings of the Boston Society of Natural History, Vol. xxiv, 1889.] ON THE GUSTATORY ORGANS OF THE MAMMALIA. BY FREDERICK TUCEERMAN. Before taking up for consideration the gustatory organs of mammalia, it may perhaps be as well to review very briefly what is known respecting the homologous organs of fishes, batrachians, and reptiles. In 1851, Franz von Leydig discovered in the external skin of fresh-water fishes peculiar goblet-shaped bodies, which he was dis- posed to regard as organs of a tactile nature. In 1863, Franz Eil- hard Schulze redescribed the goblet-shaped bodies of fishes, and considered them organs of taste. He found them in greatest num- ber where the fibres of the glosso-phaiyngeal nerve are most thickly distributed, i. e., in the mucous membrane of the palate, upon the gams and tongue rudiment, on the inner side of the gill arches, and upon the lips. In structure he found them to agree, in most respects, with the end-discs of the frog. The goblets he described as composed of two kinds of cells, viz., Sinneszellen and Sliitzzellen, or sensory and supporting cells; the former having a peripheral and central process. In 1867 Schulze observed that the peripheral extremity of the taste-cell bears a fine hair-like process, as in mammals. In 1870, he discovered in the mouth of a larval amphibian (PelobaUH fuscuti) bodies resembling in structure the goblet-shaped Organi of fishes, which he considered taste-organs. In 1872,
