COLLECTION OF SHELLS 



AT 



Chesters, Humshaugh-on-Tyne 



The collection is said to be about 150 years old, and consists 

 of shells collected in all quarters of the globe, most of thou in 

 a very good state of preservation. They are principally marine, 

 ivith a fezu land and fresh-water species. 7 he land shells 

 {snails) are chiefly West Indian^ i7iterspersed ivith a few 

 Etiropean, African, and Eastern forms. Many of the Marine 

 Shells were rarities tn their day, and some of them are still 

 very rarely seen in spite of recent researches and investigations. 



The Mollusca represented in the collection are divided 

 into three classes: — i. CEPHALoroDA ; 2. Gastropoda; 3. Pele- 

 CYPODA. The Brachiopoda, although included in this Catalogue, 

 are not now classed zvith Molluscct, on account of their dfjerent 

 organism. 



To make this Catalogue as simple as possible I have added 

 to the technical names, where practicable^ the meanings, and 

 in some cases the popular names where such exist.
