Extract

Brood protection is characteristic of the Spirorbinae although the mode of protection differs widely between species (Bailey, 1969; Knight-Jones, Knight-Jones & Vine, 1972). The way in which these protected eggs are successfully fertilized has been a subject of speculation (Gee & Williams, 1965; Franzen, 1956; Potswald, 1968). Individuals of the Spirorbinae are simultaneous hermaphrodites and the possible role of self-fertilization in their reproduction has been considered (Gee & Williams, 1965; Potswald, 1968). In the past, these problems have been discussed with the tacit assumption that no spermatheca is present in the Spirorbinae.
