A 



CATALOGUE OF THE MOLLUSCA 



OP 



NOETHUMBERLAND AND DURHAM. 



Several partial notices of the Mollusca, or, to speak more cor- 

 rectly, of the Shells of Northumberland and Durham, have from 

 time to time appeared. The earliest is that of Wallis in the 

 " Natural History and Antiquities of Northumberland," published 

 in 1769. This work contains an account of 45 species and va- 

 rieties, rather vaguely designated, after the fashion of the older 

 naturalists, but most of which can be easily recognised. They 

 consist principally of the most common and conspicuous species. 

 No further contributions to the conchology of these counties 

 appeared till 1816, when Sir Cuthbert Sharp published in his 

 " History of Hartlepool," a pretty extensive list of the shells of 

 that locality. This list appears to have been very carefully 

 drawn up according to the best information of the time, but a 

 few species have inadvertently been admitted into it, such as 

 Venus chione, Cardium amdeatum, Buccinum lineatum, and 

 Stromhus costatus, which are certainly not inhabitants of our 

 coast, and must either have come there by chance, or, what is 

 more probable, other species somewhat similar in appearance 

 have been taken for them. Several species in addition to 

 Sir Cuthbert Sharp's list were given by Mr. Hogg, in his 

 "Natural History of the Vicinity of Stockton." In 1822 

 Mr. Winch published a Catalogue of the Shells found at 

 Lindisfarne, in the "Annals of Philosophy"; stated to be 

 principally furnished by a lady. It was afterwards re-
