[None. Introduction as follows:]
The Polychaeta studied in this report were all collected by the staff of the Discovery Investigations in the R.R.S. 'Discovery,' in the R.S.S. 'William Scoresby,' in the Floating Whaling Factory S.S. 'Anglo-Norse' off the South Sandwich Islands, and by the personnel of the Marine Biological Station at South Georgia and at Saldanha Bay, South Africa. A few specimens were also procured by a member of the staff in a trawler off the Cape of Good Hope.
The stations made by the 'Discovery' have no letters prefixed to the numbers: those of the 'William Scoresby' have the prefix WS, those of the S.S. 'Anglo-Norse' SS (for South Sandwich), and those of the Marine Biological Station MS.
