The Supplementary Reports in the present Part call for no special remark. I am 

 greatly indebted t<> my friends the authors for their kindness in helping me to make 

 these contributions to our knowledge of the Biology of the Ceylonese Seas. 



Mr. Andrew Scott asks me to state that Ceylonia, which was descrihed as a new 

 genus in the Report on the Copepoda (Part I., p. 265), is, he now considers, identical 

 with Claus's genus Jurinia (' Die Copepoden-Fauna von Nizza,' 1866). As, however, 

 the name Jurinia was pre-occupied when Claus used it, Ceylonia must stand as the 

 name of the genus. Our species from the Indian Ocean (C. acv.leata, Thomp. and 

 Scott) is distinct from Cl alts' s Mediterranean form, which now becomes Ceylonia 

 armata (Claus). 



The third volume will, so far as can be foreseen, be ready about the end of this 

 year. It will contain Professor Dendy's Report upon the Sponges, part of which is 

 in type, Professor J. Arthur Thomson's Alcyonaria, Mr. E. T. Browne's Medusae, 

 Mr. G. C. Bourne's Corals, Dr. Edith Pratt's Sarcophytons, Mr. A. Scott's 

 Ostracoda, Mr. Farran's Nudibranchiata, and possibly some other papers on the 

 remaining groups of Crustacea and Mollusca, along with further instalments of the 

 Pearl Oyster Report by Mr. Hornell and myself. 



A fourth volume early in 1905, containing accounts of the remaining groups of 

 animals, articles on pearl-formation and on Mr. Hornell's recent inspections and our 

 final Recommendations as to the conservation of the Banks, will, it is hoped, complete 

 the Report.
