[None. Introduction starts as:]
Up to the present our knowledge of Japanese Polychaeta has been limited to the following four sources:
1870. E. Grube. Neue Anneliden aus Japan.
1879. E. v. Marenzeller. Südjapanische Anneliden.
1885. W. C. McIntosh. Challenger Report.
1903. J. P. Moore. Polychaeta from Japan, Kamtschatka and Bering Sea.
Limiting our attention to the Polychaeta Errantia alone, the number of species belonging to that group and made known by the above mentioned authors from the Japanese waters, amounts to seventy-fouir in all. Of this number, eighteen species are those that have been previously hnown from other parts of the world, while the rest (fifty-six) were described as new. From among the latter must be deducted the two, viz., Eunice congesta Marenz. and Glycera decipiens Marenz., which in my opinion are indubitably synonymous with the older species E. indica Kinberg and G. goesi Mgr. respectively and which therefore have to be added among the former.
Mv own researches have revealed fifty more species not recorded before from Japan. Of these thirty-two seem to be new to science.
