Liverpool Marine Biological Committee, containing reports and memoirs of work since 1885. The marine algae were named by Prof. R. J. Harvey Gibson, Prof. Weiss, Dr. Darbishire, and others. Trans. L'pool Biol. Soc. vol. 5, 1890-1, pub. 1891, pp. 83-143, contains a revised list of marine alga; of the L.M.B.C. District. Reprinted in vol. iii. of Reports on the Fauna of U pool Bay, 1892-, with pagination altered to 65-125. The first list of algas was published in 1886, pp. 312-314, by Alfred Leicester. There are ten memoirs of the L.M.B.C., containing full descriptions of typical marine plants and animals. The greater number of these memoirs relate to animals. The district embraces not only Lancashire, but the whole coast from S.W. Scotland to Cardigan, and the Isle of Man. A list of marine algae extracted from the above Transactions was given in the Southport Handbook, Brit. Assoc, meeting, 1 903, under Zoology, but no localities are given ; therefore the plants mentioned must not be considered as belonging to the county, with- I 81 II
