Asellus

Asellus, a generic name now disused, formerly applied to the cod and other Gadidae. It is retained in the pharmacopoeias, in the name of Cod-liver Oil, Oleum jecoris aselli.—The same generic name is also employed to denote a genus of small Isopod Crustaceans, one of which, A. aquaticus, is common in stagnant ponds in Britain, and is sometimes called the Water Hog-louse. This genus is the type of a family, Asellidae. See WOOD-LOUSE.
