ASCIDIA. 35 
The objects of our Committee and of the workers at our 
Biological Station have hitherto been chiefly faunistic and 
speciographic. The work must necessarily be so at first 
when opening up a new district. Some of our workers 
have published papers on morphological points, or on 
embryology and observations on life-histories and habits ; 
but the majority of the papers in our volumes on the 
“Fauna and Flora of Liverpool Bay’”’ have been, as was 
intended from the first, occupied with the names and 
characteristics and distribution of the many different kinds 
of marine plants and animals in our district. And this 
faunistic work will still go on. Ti is far from finished, and 
the Committee hope in the future to add greatly to the 
records of the Fauna and Flora. But the papers in the 
present series are quite distinct from these previous 
publications in name, in treatment, and in purpose. They 
will be called the ‘‘L.M.B.C. Memoirs,” each will treat 
of one type, and they will be issued separately as they are 
ready, and will be obtainable Memoir by Memoir as they 
appear, or later bound up in convenient volumes. It is 
hoped that such a series of special studies, written by 
those who are thoroughly familiar with the forms of which 
they treat, will be found of value by students of Biology 
in our laboratories and in Marine Stations, and will be 
welcomed by many others working privately at Marine 
Natural History. 
It is proposed that the forms selected should, as far as 
possible, be common L.M.B.C. (Irish Sea) animals and 
plants, of which no adequate account already exists in any 
text-book. Probably most of the specialists who have 
taken part in the L.M.B.C. work in the past, will prepare 
accounts of one or more representatives of their groups. 
The following have already promised their services, and 
in some cases the Memoir is already far advanced, The
