Aschelminthes

From Freepedia

The Aschelminthes (sometimes Aeschelminthes), are an obsolete phylum of pseudocoelomate and other similar animals, including as classes the Nematoda, Rotifera, Gastrotricha, Kinorhyncha, and Nematomorpha, and sometimes the Priapulida and Entoprocta. Many of these groups are no longer considered closely related and have been promoted to phyla in their own right. The name is now generally only used as an informal term.
