by a central bureau. A large amount of individual freedom 

 to the workers is absolutely essential in order to secure the best 

 results from scientific research." 



A good deal of detailed plankton work was done during 

 this year by Mr. Chadwick and others, and we published in 

 the 13th Report some excellent figures of larval forms of 

 Planarians and " Tomaria," along with Holothurian, Star-fish, 

 and other Echinoderm larvae, which eventually led to Mr. 

 Chadwick's L.M.B.C. Memoir on " Echinoderm larvae." 



By the following year, 1900, the first four L.M.B.C. Memoirs, 

 dealing with " Ascidia," " Cardium," " Echinus " and" Codium," 

 had been published, and also the fifth and last volume of the 

 Fauna, containing reports on new Copepoda by Isaac 

 Thompson, on Hydromedusae by E. T. Browne, on Turbellaria 

 by H. Lyster Jameson, and some other marine studies. At 

 the end of the volume will be found a complete list of all the 

 species of marine plants and animals recorded up to that 

 date from the Irish Sea area. This list, as it gives references 

 to the various Annual Reports or volumes of the Fauna in 

 which the record was first made, constitutes a useful index 

 to our faunistic publications up to this date. A fist of the 

 additions made since will be found at the end of this Report. 

 Amongst interesting additions made to the fauna during 

 1900 may be noted the Nudibranchs Doris diaphana and 

 Hero formosa, the Siphonophore Cupulita sarsi, the Actinians 

 Arachnaclis albida and A. bournei, and quite a number of new 

 Copepoda recorded by Andrew Scott and Isaac Thompson. 

 In this year's Annual Report we published the first of our 

 series of distributional charts, Plates I. to VII., showing the 

 physical configuration of Port Erin Bay and the neighbouring 

 parts of the coast, and the distribution of the characteristic 

 species of the leading groups of animals, as the result of our 

 dredging expeditions during the preceding eight years. 



The 15th Annual Report (1901) begins as follows : —
