kinds of plants and animals in our marine district. And 

 this Faunistic work will still go on. It is far from 

 finished, and I hope we shall still add greatly to our 

 records of the Fauna and Flora ; but in addition it might 

 be useful to produce a series of 



L.M.B.C. Memoirs. 



What I now propose is that each of our specialists 

 should carefully prepare a full account, illustrated by all 

 the necessary figures, of one or two common but 

 important animals belonging to the group upon which he 

 is an authority; and that these detailed and fully 

 illustrated accounts should be issued as a series of 

 L.M.B.C. Memoirs — obtainable at first separately, 

 memoir by memoir as they appear, and then later bound 

 up, say 5 or 6 together, in convenient volumes. I believe 

 that such a series of special studies, written by those who 

 are thoroughly familiar with the forms of which they 

 treat, will be of great value to students in our laboratories 

 and in Biological Stations, and will be welcomed by 

 many working at marine biology. It is proposed that the 

 forms selected should, as far as possible, be common 

 L.M.B.C. (Irish Sea) animals of which no adequate 

 account already exists in any text book. Probably all 

 the members of our band of specialists will be willing to 

 help in this work. The following have already promised 

 their services, and will probably treat of the species 

 placed opposite their names : — 



Professor Harvey Gibson Zostera marina. 



Mr. C. E. Jones ... ... Halidrys siliquosa. 



Professor Weiss ... ... Typical Diatoms (Biddul- 



phia, Chaetoceros, Schiz- 

 unema, and Licmophora).
