World Polychaeta Database (WPolyDb). Published at the end of 1866 but date as 1867 also seen used. After the last page 357, there is an erratum with a year date as 1867 printed at the bottom. However this could be a later insertion. The next article (number 10) is dated Wednesday 12 December, 1866. Date is 1866 in Theel (1910). Contains only Sedentaria. A number of Kinberg Errantia, especially Nereididae species were wrongly linked in WoRMS to this part of the 'Annulata nova'. This now corrected.
