While part 5 (Day, 1960) described the errant species obtained by dredging and diving around the Cape coasts, the present paper deals with the sedentary species. However more dredging has been done since part 5 went to press so that the list of stations is even longer. At the same time it is convenient to include a few new records for South Africa made by shore collecting.
This series started in 1951 (Day, 1951) is now nearing its end. It has dealt with the Polychaeta collected on shores and estuaries of Moçambique, Natal and the Cape and now the shelf fauna obtained by dredging off the Cape down to about 200 metres has been described. There remains the shelf fauna off the Natal coasts, but Natal is a long way from our base in Cape Town and it will be some time before sufficient material has been accumulated to make a publication worth while. In the meantime a monograph with brief descriptions and keys to all the species known from South Africa has been drafted and revised several times as new species appear and old ones become better known. For this reason no keys will be included in this paper.
