PREFACE. XI 



Mr. R. MURDOCH, of Wanganui, devoted much time t<> 

 collecting and dissecting non-marine as well as marine Mollusca, 

 and has published a number of valuable papers in the Trans. 

 N.Z. List., and the Proc. Mai. Soc. It is much to be regretted 

 that he has been unable to continue his good work during 

 a number of years. 



Mr. JUSTICE GILLIES, in 1881, took Dr. Sinclair's collection 

 of New Zealand shells to the British Museum, and had them 

 named by Messrs. G. B. SOWERBY, Jim., and EDGAR A. SMITH. 

 The result was published in the Trans. N.Z. lust., vol. xiv. 



Mr. JAMES ADAMS published a valuable list of the land and 

 fresh-water Mollusca of the Thames Goldfields in the Trans. N.Z. 

 Inst., vol. xix. 



Amongst those who helped to advance our conchological 

 knowledge the following should be mentioned : Dr. W. B. 

 BENHAM, Major T. BROUN, Dr. CHARLES CHILTON, Messrs. R. 

 HELMS. RICHARD HENRY, Miss M. MESTAYER, Messrs. SHANL>. 

 W. W. SMITH, C. SPENCER, C. TRAILL, and W. H. WEBSTER. 

 some of whom published papers on New Zealand Mollusca. 



Mr. T. \V. KIRK also did some collecting, and published 

 a few short papers on Mollusca ; especially valuable are his 

 communications on the large cuttlefishes. 



Dr. SCHAUINSLAND visited New Zealand and the Chatham 

 Islands in 1896-97, and Dr. THILENIUS from 1897 to 1899, 

 partly for the purpose of collecting specimens for the museums 

 in Bremen and Berlin. Reports on the Mollusca were published 

 by Dr. R. BERGH, Dr. L. H. PLATE, and Dr. KURT WISSEL. 



During the year 1902 Messrs. K. LUCAS and G. L. HODGKIN, 

 of Cambridge, made a collection of the fauna of a typical 

 series of lakes in New Zealand, most of the Mollusca being 

 obtained by dredging. They were kindly handed over to me 

 for description, and the result was published in the Trans. 

 N.Z. Inst., vol. xxxvii. 



In January, 1904, a party organized by Mr. CHARLES HEDLEY. 

 Conchologist of the Australian Museum, Sydney, dredged in 

 110 fathoms east of Great Barrier Island, with good results. 

 The shells obtained were worked out by Messrs. C. HEDLEY. 

 W. H. WEBSTER, R. MURDOCH, and myself, and the results 

 published in the Trans. N.Z. Inst., vol. xxxviii.
