of the alphabet is added after the number engraved 

 on the Plate. Thus + indicates a shell half an inch 

 long; + three quarters of an inch; a an inch; a an 

 inch and a quarter ; a + an inch and a half ; a + 

 an inch and three quarters; b two inches; c three 

 inches, and so on: m denotes shells of the natural 

 size ; and m such as are magnified. The shells on 

 the Plate annexed are given as specimens of the size 

 and manner in which the figures are executed, — with 

 this difference, that the copper is much larger, and 

 the shells placed nearer together, so that each Plate 

 includes sixty figures. 



Fig. 1. represents the Solen Siliqua, eight inches long. 



Fig. 2. Lepas Tintinnabulum, two inches. 



Fig. 3. Venus Dione, an inch and a half. 



Fig. 4. Tellina interrupta, two inches and three quarters. 



Fig. 5. Conus capitaneus, two inches. 



Fig. 6. Nautilus Pompilius, eight inches. 



It has been the object of the author to combine accu- 

 racy with economy ; the figures in the Index Testa- 

 ceologicus (though most correctly drawn and highly 

 finished in colours) being less than three farthings 

 each.
