THIS Catalogue is published with the three-fold object 
 of affording a guide to the collection ; of making known its 
 deficiencies (which are many,) ; and to show what the 
 Museum has to offer in exchange for shells not yet in the 
 collection. 
 
 Those species of which there are duplicates are marked 
 with one, two, or three asterisks ; the first indicates that 
 the number is very limited ; the second that it is greater ; 
 and the third that a considerable number is available for 
 exchange. 
 
 Examples of shells not in this Catalogue will be thank- 
 fully received either as donations or in exchange.
