ACCOUNT OF 



Since the reading of my paper on the North 

 British Testacea, several shells have been met 

 with not there mentioned, and others have, 

 through the kindness of my friends Mr P. Neill 

 and the Reverend Mr Fleming, been added to 

 my cabinet. Anxious that this Catalogue should 

 be as complete as possihle, I beg leave to add these 

 last discoveries as an Appendix to the former. 



I think it proper here to mention, that the 

 plate accompanying this Catalogue, contains Shells 

 not to my knowledge before figured, and which 

 are mostly uniques. These, with the exception 

 of one or two, are all described by my friend G. 

 Montagu, Esq; in his excellent work on Testa- 

 cea, and its Supplement. The Chama Cor is of 

 its natural size \ and with confidence I can say, it 

 is the only real British specimen that has been fi- 

 gured by any author.
