with prongs or fingers ; but all the other 

 authors have intermixed them with the 

 foregoing genus. 



The fpecies are few, but they are fine 

 Shells. 



I have now gone through the firil: gene* 

 ral divifion of Shells, or Univalves. This 

 divifion is the moll numerous of the tefta- 

 ceous animals ; for I do not hefitate to 

 pronounce, that the fpecies of Univalves 

 furpafs, by great numbers, the two other 

 general divifions of Bivalves and Multi- 

 valves joined together. In this divifion of 

 Univalves the wonderful works of the crea- 

 tion are alfo manifefted by the immenfity 

 of beauties in their colours and flruftures. 

 On this account it is that Univalves are 

 the choicefl objeds of coUeflors, and bear 

 more value than Bivalves or Multivalves ; 

 for few of the latter ever fetch above five 

 or fix guineas, while numbers of the Vo- 

 lutes and other Univalves bear to ten, twen- 

 ty, or thirty guineas, and even greater prices.
