PREFACE. 



At the same time Dr. KRONE collected some land-shells on 

 the Auckland Islands. 



The antarctic expedition under C. E. Borchgrevink, in the 

 " Southern Cross/' brought one new species from Campbell Island 

 and three from the Auckland Islands. They were described 

 and figured by EDGAR A. SMITH in the " Report on the Col- 

 lections of Natural History made in the Antarctic Regions 

 during the Voyage of the ' Southern Cross,' : 1902. vii, Mollusca. 



With the " Catalogue of Marine Mollusca of New Zealand/' 

 1873, Captain F. \V. HUTTON laid the foundation of a large 

 amount of work which he afterwards did, including his " Manual 

 of the New Zealand Mollusca.'" Captain Hutton greatly ad- 

 vanced the knowledge of our Mollusca not only by systematic- 

 work, but also by his numerous anatomical researches. He 

 was at all times ready with his advice and assistance to other 

 workers in science, and ever since arriving in New Zealand the 

 writer of these lines was fortunate enough to enjoy the benefit 

 of Captain Button's wide knowledge, and it was greatly due to 

 his stimulus and help that the study of the marine Mollusca 

 was taken up. 



Mr. T. F. CHEESEMAN did extensive collecting and dredging 

 in Auckland Harbour. He published in the Trans. N.Z. Inst. 

 lists of the Mollusca of the Auckland Harbour and of the vicinity 

 of Auckland, followed by papers on new nudibranchiate and 

 opisthobranchiate Mollusca. 



Of recent collectors, special mention should be made of 

 Captain J. BOLLONS, of the Government steamer ' Hinemoa." 

 For a number of years he has been collecting and dredging in 

 many parts of New Zealand and its subantarctic islands, and has 

 thus materially helped to increase the number of species, and to 

 enlarge our knowledge of geographical distribution. 



Mr. A. HAMILTON, Director of the Dominion Museum, has also 

 done very much to further New Zealand conchology by collecting 

 in many parts of the Dominion, and also on Macquarie Island. 



Mr. CHARLES COOPER, of Auckland, has collected Mollnxrn 

 in the vicinity of Auckland and the northern parts of New 

 Zealand for many years, and has published in the Trans. N.Z. 

 Inst., vol. xxxi, a useful list of the marine shells found at 

 Whangarei Heads.
