None. General discussion: The discovery of only three new species of Spirorbinae amongst a total of 13 species, which were found in a series of intensive collections, is in line with current discoveries elsewhere and suggests that the stage is approaching when most of the shallow-water species from warm seas will have been described. The distribution of Spirorbinae around the Hawaiian Islands and the contributions towards zoogeography which this study has made is discussed on p. 150-182 in a separate joint paper (Vine et aI., 1972).
