New Pogonophora from the northeast Pacific Ocean

Abstract

Five species of Pogonophora have been found in collections of benthos from depths of 200 to 2680 meters off the coast of British Columbia, Canada. They include two species already known from the Pacific, Polybrachia canadensis and Siboglinum pusillum; a new species of Lamellisabella, and a new species of Siboglinum. The fifth species is probably another new species of Siboglinum, but the specimens are not sufficiently complete for definite determination.
