wlu'u oponiiio^ lip a new distrifl. Soiiio of the workers 

 Jiave published papers on iuorplioh)gieal points, or on 

 enibryolog'y and obserA^ations on life-histories and habits: 

 but the majority of the papers in- the volumes on the 

 " Fauna and Flora of Liverpool Bay "' have been, as was 

 intended from the first, oecupied with the names and 

 characteristics and distribution ol the many different kinds 

 of marine plants and animals in our district. And this 

 faunistic work will still go on. It is far from finished, 

 and the Committee liope in the future to add g-reatly 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 Avill be issued separately as they are 

 ready, and will be obtainal)le ^lemoir 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 Avho are thoroughly familiar with the forms of which 

 they treat, will be found of value by students of Biology 

 in laboratories and in Marine Stations, and will be 

 welcomed by many others working pi ivately at Marine 

 2s atural 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 the 

 text-books. Probably most of the specialists Avho 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 many cases the Memoir is already far advanced. The 

 first Memoir appeared in October and the second in 

 December, 1899, the third in February, and the fourth in 

 April, 1900, this fifth one will be issued about the end of
