MARINE ALG OF THE L.M.B.C. DISTRICT, 129 
is especially true of the minute parasitic forms among the 
Rhodophycexe. I trust that ere the time arrives for the 
publication of the Third L.M.B.C. Report I may be able 
to justify that remark, and to largely increase the lst 
which at present represents our knowledge on the subject. 
Since the establishment of the Biological Station on 
Puffin Island, Anglesey, the opportunities of satisfactorily 
dealing with the many and interesting problems connected 
with the structure, distribution, and life-history of marine 
Algee, have been enormously increased. The zone between 
high and low water marks abounds in forms belonging to 
all the main divisions of the group, and I feel sure that a 
thorough exploration of that zone (which I purpose making 
during the ensuing summer) will result in the discovery of 
many species new to the district, if indeed we are not 
fortunate enough to meet with species new to British seas. 
So far as I can discover, the literature on the Alge of 
the district includes only several short papers published by 
Mr. F. P. Marrat, of the Liverpool Free Public Museum, 
in the Liverpool Naturalist’s Scrap Book (1863-1864); a 
list quoted by the Rev. H. H. Higgins in the First Report 
of the L.M.B. Committee,* indicating those species which 
were found on the shores of Puffin Island by Mr. Marrat 
during an expedition of the Liverpool Naturalists’ Field 
Club, in June, 1865; a list of Algee from Puffin Island, 
published by Mr. C. 8. Gregson in the Naturalist, vol. i1.; 
and the list by Mr. Leicester, already referred to. I have 
incorporated these lists in the present report, not only 
because I am anxious to present as complete a catalogue 
as possible, but also because Mr. Marrat’s lists are hidden 
in the pages of a long extinct periodical, very scarce and 
not easy of access. The copy I have consulted is in the 
Free Library of Liverpool.
