2. In zoology, the term Vermes or worms has been applied to different divisions of invertebral animals, by different naturalists. Linnæus's class of Vermes, includes the following orders, viz. Intestina, including the proper intestinal worms, the earth-worm, the hair-worm, the teredo, and some other marine worms; Mollusc; including the slug, and numerous soft animals inhabiting the water, particularly the sea; Testacea, including all the proper shell-fish; Zoophyta, or compound animals, including corals, polypes, and spunges; and Infusoria, or simple microscopic animacules. His character of the class is, – spiracles obscure, jaws various, organs of sense usually tentacula, no brain, ears nor nostrils, limbs wanting, frequently hermaphrodite. This class includes all the invertebral animals, except the insects and erustacra. The term Vermes has been since greatly limited, particularly by the French naturalists. Lamarck confined it to the intestinal worms, and some others, whose organization is equally simple. The character of his class is, suboviparous, body soft, highly reproductive, undergo no metamorphosis; no eyes, nor articulated limbs, nor radiated disposition of internal organs. – Linnæus. Lye.
