In the following pages are described a number of new species of Polychaeta, belonging to several families, from the collections of the Alaskan Salmon Commission of 1903. Three papers noticing other novelties in these collections have already been published in these
Proceedings with the approval of the Commissioner of Fisheries, through whose kindness the material was placed in my hands for study. The full report on all of the species represented will appear in the Bureau of Fisheries
Bulletin.
