We beg to inform students and collectors that we have for sale 

 6000 species of Marine, Land, and Fresh-water Shells. These we 

 offer either as single specimens or in large or small collections. 

 Specimens can be furnished in either their natural condition, or 

 cleaned to bring out their brightest colors. We are constantly re- 

 ceiving boxes of shells froin our correspondents in Australia, Japan, 

 the Philippines, etc., which gives us exceptional opportunities of 

 offering for sale rare and desirable species. 



We also carry in stock a number of species in alcohol for ana- 

 tomical purposes. 



We call attention to our Catalogue of Mollusca, 120 pages, 86 

 wood-cuts, price 30 cents. To this we have lately added two 10 

 page sujjplements.
