Date of publication Czerniavsky presented the first part of his Black Sea Vermes report to a society meeting in October 1880 and it seems certain it was not published until 1881. This is confirmed by the title page of issue 55(4) on https://www.biodiversitylibrary.org/page/34420728 were it is said that 55(4) is printed in 1881. The year 1880 in the footers on some pages do not represent the year of print.
