The Council of the Marine Biological Association of the United Kingdom has determined to issue to its members notes and reports concerning the work of the Association in the form of a Journal, which will appear at intervals, determined by the amount of material ready for publication. It is not proposed to limit the contents of this Journal to formal reports, nor to publish in it lengthy scientific memoirs, but to include within its pages, besides the official statements of the Council, brief records of observations relating to the marine biology and fisheries of the coasts of the United Kingdom which may appear to have a definite bearing upon the work actually in progress under the auspices of the Association. With this object in view the Council of the Association invite communications from fishermen and naturalists, which may either be printed in full in this Journal or form the subject of a note.
