Summary: The number of species in the present collection is 88; of these 54 species occur in the Ross Sea and McMurdo Sound, 33 in the waters round New Zealand (one of which, Phyllodoce madeirensis, is common to both areas), and 3 on the shore of South Trinidad in the Atlantic. There remain to be examined the representatives of the two families Tomopteridae and Alciopidae; of these pelagic worms a large number were collected, especially of the former. They are chiefly from the neighbourhood of Nelson, only a few individual Alciopids having been included in the Antarctic gatherings. I hope to give an account of these pelagic forms in a separate Report. It will be convenient to consider the Antarctic and the New Zealand species separately; in the following list the species from these two areas are distinguished by the letters A. and N.Z. respectively.
