Abstract

A new species of colonial Styelid ascidian of the genus Polyzoa was found attached to the test of solitary ascidians collected by divers off the coast of Georgia, U.S.A. The colony of this new species, consisting of small sandy zooids, is cryptic and difficult to detect. The species is characterized by three longitudinal branchial vessels on each side of the body and is the second species of the genus reported for the Atlantic.
