None. Begins: "The polychaetous annelids comprised in the following list have all been collected within a radius of twenty miles of Nanaimo, Vancouver Island. I have collected all the species listed personally, though a few of them were already represented in the collection of the Marine Biological Station, Departure Bay, which was kindly placed at my disposal for study by Dr. C. Maclean Fraser, the Director of the station. I am also indebted to Dr. Fraser for the dredged material I have examined, for access to the resoirrces of the station in the matter of literature, and for assistance in other directions. The list cannot claim to be a complete record of the polychaetes occurring within the area, since sufficient dredged material, particularly from depths exceeding 25 fathoms, has not been examined, but it probably comprises most of the species occurring at this and lesser depths, and of the shore forms. It is proposed to publish the list in instalments as work on the groups is completed. The present instalment comprises the Syllidae, Hesionidae, Aphroditidae, Amphinomidae; Palmyridae, Polynoidae, and Sigalionidae, and records 43 species."
