[None. Introduction begins:]
The following paper contains a list of old, and a description of a few new species of Pacific polychaetous annelids belonging to the University of California which, through the courtesy of Professors W. E. Ritter and C. A. Kofoid, were submitted to me for study. As a result of the earlier papers of Johnson, and the later elaborate work of Moore, our knowledge of the Pacific coast Polychaeta is very complete and I was prepared to find, what proved to be actually the case, that the greater number of the specimens submitted to me had already been described.
Twelve new species were found in the collections and are here described: Panthalis pacifica, Nereis notomacula, Spio acuta, Scolecolepis alaskensis, Polydora californica, Streblosoma crassibranchia, Trophonia minuta, T. inflata, Ophelina magna, O. mucronata, Laonome oculifera, and Branchiomma disparoculatum.
While it was not my original intention to do more than publish a description of these new species, I have, at the request of Professor Kofoid, included all of the old, with the intention of thus securing a more complete and easily accessible list of the localities from which the various species were collected, as well as a record of whatever data concerning depth of water and character of bottom were available. The collections included some material from Honolulu and from localities along the coast as far north as Alaska, as well as material obtained with trawl and tow-net during the explorations of the Marine Biological Station of San Diego. Localities relative to the former are entered in sequence from north to south and those relative to the latter according to the haul numbers under which the collections are accessioned (see Ritter, 1914).
