college students and young amateurs formed a large pro- 
portion of the workers, the want has been constantly felt 
of a series of detailed descriptions of the structure of 
certain common typical animals and plants, chosen as 
representatives of their groups, and dealt with by spe- 
clalists. The same want has probably been felt in other 
similar institutions and in many College laboratories. 
The suggestion has been received so cordially that we 
have been encouraged to carry out the scheme without 
delay, and the first papers of the series are now being 
issued. 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 
first Memoir (No. I., Ascidia) was published in October, 
price 1s. 6d.; the second (No. II., Cardium) is now in 
type, and will be issued in a few weeks; the third 
(No. III., Echinus) will appear before the end of 1899. A 
couple of Botanical Memoirs will, it is hoped, be ready 
early in 1900, and others will follow in rapid succession.
