vul PREFACE. 



Another very capital error, which is ty- 

 pographical, occurs, p. 128, 1.8, viz. 'nhefe 

 animals are abfolutely loofe from their 

 Ihells;" whereas it fliould be, *^ thefe ani-p 

 mals are no( abfolutely loofe from their 



ihells." 



P. 135, In the lift of Univalves, after 

 AuresMariniE, add Vermiculi and Dentalia ; 

 and after Cochleae, dele Turbines. 



I repeat i^y fubmiftion to the candid 

 judgement of the learned ; and fliall con- 

 clude my preface with the motto ufed by 

 the celebrated Dr. Lifter, in fome of his 

 ornamental plates to the firft edition of hisj 

 Hiftoria Conchyliorum : 

 Joculare tibi videtur; 



et fane bene : 

 dum nihil habemus majus, 

 Calamo ludimus.
