FINE LAND SHELLS. 



I HAVE For Sale one of the Largest and Most Elaborate

 now arriving every week. Beautiful Specimens in Great Variety will be 

 offered Very Cheaply. Selections of any size sent on request. If my success 

 continues within the next three years I shall be able to furnish about every known 

 species at most reasonable prices. Correspondence solicited with interested 

 parties. Also Exchanges for Fine Exotic Land Shells only needed in my
