J^OTICE. 



The insulated residence of the author, precluding a re- 

 ference to any other cabinet than his own limited* one, or 

 to any exten^ire library, excites a fear that some errors in 

 nom^aciatiire may occur in this work, that under more 

 advantageous circumstances might be avoided. In order 

 therefore to render the "Conchology," as perfect in this 

 respect as possible, and that the interests of science may not 

 be endangered by his local disadvantages, the author in- 

 vitesjudicious criticism, which shall be inserted on the 

 cover of the number with due acknowledgment to the 

 writer.
