title: Three new species of Glossobalanus (Hemichordata: Enteropneusta: Ptychoderidae) from western North America.
abstract: Twenty three enteropneust species have been described from the west coast of North America, including one species from the family Ptychoderidae; Glossobalanus berkeleyi from the Salish Sea, Vancouver Island. Here we use morphology to describe three additional species of acorn worms in the genus Glossobalanus: G. williami from Cape Arago, Oregon; G hartmanae and G. barnharti from La Jolla, California. Notes on the habit and localization of each species as well as a dichotomous key to the genera of the family Ptychoderidae are provided.
