  Mastax \Mas"tax\, n. [NL., fr. Gr. ? mouth, jaws.] (Zool.)
        (a) The pharynx of a rotifer. It usually contains four
            horny pieces. The two central ones form the incus,
            against which the mallei, or lateral ones, work so as
            to crush the food.
        (b) The lore of a bird.
