PHORONIDEA FROM THE PACIFIC COAST OF NORTH AMERICA

Abstract

Six phoronids from the west coast of North America, Phoronis vancouverensis, Phoronis pallida, Phoronis psammophila, Phoronis ovalis, Phoronopsis harmeri, and one that is possibly Phoronis architecta, are described. Phoronopsis harmeri is considered to be synonymous with Phoronopsis viridis. Taxonomic relationships within the Phoronidea are discussed. It is suggested that the phylum may most naturally be divided into four categories of wide geographic range. The characteristics of each of these categories are discussed.
