THE alterations hi this edition^ consist in the introduc- 

 tion of some species which were unknown at the time of 

 Linnaus : the division of the genera into classes, irherehy 

 the different characters of the genus may be more readily 

 recognized: the addition of the English names to many 

 of the species ; a comprehensive nomenclature of the terms 

 used in Conchology ; and lastly, by the embellishment of 

 three new plates: the Frontispiece shewing four genera 

 of spiral shells ; and the two others exhibiting the hinges 

 of Bivalves, and displaying the peculiarities of some par- 

 ticular shells.
