- n. A little tongue or tongue-like part or process; a ligula. Specifically— In embryology, a cartilaginous strap or bridge on each side of the end of the notochord, connecting the trabeculæ cranii with the parachordal cartilage or basilar plate of the skull of the early embryo.
- n. In zoology: [capitalized] The typical genus of Lingulidæ. The species are numerous; they are mostly fossil, and go back to the Cambrian group, but several are still living. They are found in the sand of the seashores of most parts of the world, living buried in the sand about low-water mark. One is common on the coast of North Carolina. Its shell is bivalve, about an inch long, fiattened, each valve shaped like the bottom of a smoothing-iron, and the two valves working loosely upon each other sidewise, not opening and shutting like those of bivalve mollusks. From the pointed end protrudes a stalk or peduncle from an inch to several inches long, of stiff gristly consistency, and this organ may be incased in a tube formed of sand, like the case of a tube-worm. The broad end of the shell is fringed with little processes. The shell is thin and of a horny texture. The appearance of a lingula is thus somewhat like that of a stalked barnacle or acorn-shell (Lepas), though the animal has no special affinity with a cirriped. The living American lingulas are now placed in a restricted genus Glottidia, the one above described, best known as L. pyramidata, being now called
G. audebarti . See cut underLingulidæ . - n. Pl. lingulas (-läz). Any species of the genus Lingula or family Lingulidæ; a lingulid or tongue-shell.

The Christian Foundation, Or, Scientific and Religious Journal, Volume 1, January, 1880
“The superior vermis is subdivided from before backward into the lingula, the lobulus centralis, the monticulus and the folium vermis, and each of these, with the exception of the lingula, is continuous with the corresponding parts of the hemispheresthe lobulus centralis with the alæ, the monticulus with the quadrangular lobules, and the folium vermis with the superior semilunar lobules.”
“The anterior medullary velum (page 793) fills in the angular interval between the superior peduncle, and is continuous behind with the central white substance of the cerebellum; it is covered on its dorsal surface by the lingula of the superior vermis.”
“The anterior medullary velum (velum medullare anterius; valve of Vieussens; superior medullary velum) is a thin, transparent lamina of white substance, which stretches between the superior peduncle; on the dorsal surface of its lower half the folia and lingula are prolonged.”
“The lingula (lingula cerebelli) is a small tongue-shaped process, consisting of four or five folia; it lies in front of the lobulus centralis, and is concealed by it.”
“It overlaps the lingula, from which it is separated by the precentral fissure; laterally, it extends along the upper and anterior part of each hemisphere, where it forms a wing-like prolongation, the ala lobuli centralis.”
“Between the lingula and the canine tooth the cartilage disappears, while the portion of it below and behind the incisor teeth becomes ossified and incorporated with this part of the mandible.”
