Cut 5. Mimus polyglotius; section throuc!;li the base of the tongue (Fig- 3, line 1) By. hyoid; gV, dorsal, gV, ventral, glands; K, VI, longitudinal muscles; V, blood vessel. 29 diam. basal portion, at the point where the cornu are just separating from the body of the hyoid, the- three forming a triangular central bone, Hy, which contains a number of medullary cavities, filled with a peculiar tissue, which oc- curs also in the other bones of the hyoidean apparatus. This tissue consists of numerous large, clear spaces, separated from one another by thin partitions — 1 think each space must be a large vesicular cell, for I can occasionally see a small nucleus lying against one of the The tissue is permeated by numerous blood-vessels, which can be easily seen passing in and out among the clear spaces (cells ?) of the tissue. The epithelium is quite thick, with a well-developed corneous layer, and is thicker on the under, than on the upper, side. The break below is an accidental injury. In this part of the tongue there are only longitudinal muscles, the large I' above, and the small l" below. Under the dorsal epithelium is a layer of conglobate glands, gV, which open by short ducts directly upon the upper surface. These glands, which are not mentioned by previous observers, are probably homol- ogous with the glands on the back of the mammalian tongue. Laterally and ventrally, are two long and tubular glands, gl", with follicular walls. They are oval in section, have a rather small lumen and a fibrous tunica propria, which sends up partitions between the folHcles, which make the principal part of the walls of the glands. The fol- licles are narrowest at their mouth, and widen towards the base, the height of the lining cylinder epithelium increasing, but
