it is very nearly allied ; but we have fuffered the trivial 

 name of the only Britijh fpecies to remain, as well as that of 

 the generic, and have only affixed more appropriate charac- 

 ters to the genus. 



A new genus has alfo been formed out of fome of the Mac^ 

 tree and Mycc which ftri^Hy belong to neither, but had been 

 capriciouOy placed amongfl them for want of having afhgned 

 to fliells naturally of the fame family, more congenial cha- 

 ra(5lers. This we have intitlcd Ligula, to which we refer 

 for further information. 



We have nothing to add to this Introduction but to fay, 

 that we Ihall avail ourfelves of thefe fupplementary Iheets 

 to make a few additional remarks, where farther in ve (liga- 

 tion has thrown new light on the hiflory of any particular 

 fpecies before defcribed ; and we have the pleafure to an- 

 nounce that not lefs than feventy new have been added to 

 the catalogue of Briti/Jj fliells.. 



It now only remains with us to alk the fame indulgence 

 we experienced in the former part of this work, which has 

 not been a little flattering to our exertions in the develope- 

 ment of natural hiftory. And we trufl our various fcientific 

 friends, to whom we return our grateful acknowledgements, 

 will continue their remarks to us on the various branches of 

 Zoology as heretofore.
