(abstract.)

The genus Phreoryctes has been known to zoologists since the year 1843, but there is no published account of the reproductive system sufficiently detailed to permit of comparison with other Oligochæta. The gonads (testes and ovaries) and spermathecœ were discovered by Leydig, who did not distinguish between ovaries and testes, owing to the immature condition of the specimens studied. This writer considered that the genital products were evacuated through the nephridia of their segment. The supposition is, however, incorrect, as genital ducts exist. Mr W. W. Smith of Ashburton, New Zealand, forwarded to the author in the spring of 1888 a single specimen of a new species of Phreoryctes, which was described in the Annals and Magazine of Natural History for June 1888 as Phreoryctes Smithii. In that paper the gonads and their ducts were briefly described and figured.
