Canalis semicircularis externa (E.). Only the beginnings of this canal are shown, one of them opening with the superior and one with the posterior canal (§ 1441). Cochlea.—This is represented as unrolled and the ventral surface removed so as to expose the scalas and the lamina spiralis (§ 1440). Cutis, the skin.—It is continuous over the meatus and becomes very thin as it extends over the membrana tympani to form its ectal layer. Fenestra rotunda (Ft. rt.) s. Fenestra cochlea.—In life this is inclosed by a mem- brane. It leads into the scala tympani of the cochlea. Fenestra ovalis (Ft. ov.) s. Fenestra mstibuli.—This is the passage from the tympa- num to the vestibule. In life it is covered by the base of the stapes with its connecting soft parts. Incus.—The middle bone of the ear. It is also called anvil and dens molaris (§ 1437). Labyrinthus.—This is the third and last or sentient part of the ear. It is often called internal ear. Lamina spiralis (Lm. spr.).—This is a plate of bone arising from the modiolus or col- umn of the cochlea, and with its membranous continuation divides the cavity of the cochlea into the two scalae (Fig. 138). Ligamentum incudis (Lgt. inc.).—The ligament holding one of the processes of the incus to the wall of the tympanum. Malleus.—The first of the small bones of the ear. It is by far the largest of the three. It gains its name from its resemblance to a hammer. Its handle stretches partly across the Mb. tympani. Meatus.—The name is written in the meatus ectalis or passage fro
