It has been my desire, so far as possible, to deposit the types of new species in the 

 British Museum. In the case of some of the smaller forms the type specimens have 

 become more or less used up in the process of examination, or exist only in the form 

 of fragments on microscope slides or as sections. In other cases, the authors are still 

 actively working at the groups in question, and it has been represented to me that 

 the best interests of science would be served by allowing all the specimens to remain 

 in their hands for the present. I have, however, already sent to the British Museum 

 the types of new species, and, in some cases, representatives of additional species, in 

 the following groups : Echinodermata, Pantopoda, Hemiptera, Polyzoa, Cumacea, 

 Amphipoda, Leptostraca, Schizopoda, Stomatopoda, and, in the case of other groups, 

 the specimens are now in process of being picked out for packing and transmission. 



I am very much indebted to my Zoological friends who have so ably helped me by 

 taking charge of separate groups. The Supplementary Reports which they have 

 contributed form a valuable body of information on the marine fauna of Ceylon which 

 is indispensable in discussing any biological problems in that part of the Indian 

 Ocean. A few corrections and additions kindly supplied by the authors will be found 

 at the end of this volume. 



I desire once more to acknowledge the very efficient help which I have received 

 from Mr. JAMES HORNELL, F.L.S., both in the initial investigation and also during 

 the production of this Report. Even after Mr. HORNELL ceased to be formally my 

 assistant in the matter, and was appointed to a responsible post under the Ceylon 

 Government, he continued to spare no pains to keep me fully informed of the changes 

 in the condition of the pearl banks and to obtain any specimens or evidence that 

 might be required to clear up points in doubt.
