NOTES ON POLYCHAETA FROM CALIFORNIA TO PERU

Abstract
Twenty-two species of Polychaeta are recorded, of which eleven were taken in the plankton, but some of these are certainly swimming forms of benthic species. The remainder were either dredged, collected intertidally, or by diving. Thirteen species come from Peru, six from California, and one each from Mexico, Panama, and Cocos Island. Three of them are new to science. [Nereis (Neanthes) mancorae (Nereidae), Ancistrosyllis lpngicirrata (Pilargiidae), and Prionospio ornata(Spionidae).].
