NOTE. 



Reference in following lists of DUPLICATES is made to the pages of the new complete cata- 

 logue of the Marine Mollusks of Japan, with descriptions and illustrations of new species, and notes 

 on others the collections of Frederick Stearns by Henry A. Pilsbry, Conservator of the Conchologi- 

 cal Section of the Academy of Natural Sciences, Philadelphia, Pa., U. S. A. 



The above catalogue was published by Frederick Stearns, 1895, pp. 204, plates XI, 140 figures. 

 Price in paper covers, $1.00; bound in cloth, $1.50. If by mail, 12 cents extra must be sent for pre- 

 paying postage. (See advertisement on last page of cover.) 



I desire and expect to use these duplicates to obtain in exchange from other and original col- 

 lectors, desirable species of shells, echinoderms, crustaceans, star fishes, corals, sponges, etc., etc., 

 not now in my collection. 



Persons receiving this list and desiring to exchange will send me a list of what they have to offer 

 of the rarer species, not necessarily showy or striking, among which new and undetermined species 

 and varieties will be welcome, so long as they are known to be such, and from the hands of the 

 original collectors. I have no lists of desiderata to send to any one. 



Postal charges in all cases to be paid by the sender and not by the receiver, unless under special 

 arrangements to the contrary. The charges on large shells, or on large parcels of shells which can 

 not be sent by mail, but which must go by express, or as freight by rail, must be paid by the receiver. 



Correspondence will be acceptable in Spanish, German, French, Portuguese, as well as English. 



Persons having rare shells which they prefer to sell for cash only will be treated with. 



The prices affixed to the shells on this list are believed to be reasonable, and in offering shells for 

 exchange I expect my correspondent will affix a price to each species offered, in order that an 

 exchange or sale may be evenly and promptly adjusted. 



This list comprises the duplicates of the collections of two visits to Japan, 1889-90 and 1892. The 

 quantity of new material obtained Jm'tfcs la& \sft fiQl&yJbdJthe issue of this list for reason that two 

 years passed before the new and ccnipfete 'catalogue' of Jtpan Marine Shells could be written and 

 published. 9 * .< * e c ",** 



A list of DUPLICAT/F/'LoJo C0o, f ^a*vatian; ajid SfculVf eji flhella was printed in 1894, but not 

 mailed to conchologists until "now (189&)/when it is enclosed with this list. 



In ordering, please give the name of the list, whether Japanese, Loo Choo, Hawaiian, or other. 

 Mention page and species, number wanted, and price. 



Collectors and dealers wishing any of these shells, and not having desirable species to offer in 

 exchange, will please write their wishes. 



Some species are in considerable numbers, and shell dealers wishing to purchase such may write 

 for particulars. 



Where two prices are given, it is for varying sizes, quality, or quantity. 



The largest number of species of shells in the new catalogue are those of rare museum types here 

 and abroad, and of those of which I only found one or few, and hence those are retained as types 

 in my personal general collection now displayed in the rooms of the Detroit Scientific Museum.
