The error of authors in fetting afide 

 the figure of the mouth, which I make

 more vifible in any family of the tefta- 

 ceous animals, than in this. For the 

 Shells called Buccina by the feveral Con- 

 chologifts, inftead of being a fet of fimi- 

 lar mouthed Shells, is indeed a farragO, 

 or jumble of feveral families, all placed
