XVI.—On the Anatomy, Histology, and Affinities of Phreoryctes

Abstract

Some time since I received from Mr W. Smith of Ashburton, New Zealand, a single example of a worm belonging to the little known genusPhreoryctes, and published in theAnnals and Magazine of Natural Historyfor June 1888, a short account of the reproductive organs of this worm, for which I proposed the name ofPhreoryctes Smithii.More recently (November 1888) I have received, through the kindness of the same gentleman, a large number of specimens of the same species; the study of these enables me to offer to this Society a more complete account of the structure ofPhreoryctes, which is at present very imperfectly known. It will be seen, however, that the present paper, though more extended, and dealing with organs to which little or no reference was made in my former paper, contains no important correction of facts stated in that paper. I have also appended (p. 638) a discussion of the systematic position and affinities ofPhreoryctes.
