except Oyprcea leueodom ; while it contains such rarities as Cyprcea 

 barclm/i, C. zanlce, two specimens of C. ynttatn, large suites of C. 

 ficottli, C. thersites, C. umbl./icata and very large and handsome series 

 of the more coramon species. Both collections are still in cabinets 

 of drawers and not publicly exhibited. 



The collection of shells on exhibition in the Liverpool, or Derby 

 Museum, as it is called, although not large, is exceptionally fine, and 

 represents a great deal of care in its selection. A few species or 

 genera of fossil forms closely allied to living inollusks are incorpora- 

 ted with the latter. Very interesting features of the museum are its 

 aquaria, where both fresh water and marine inollusks may be seen 

 alive. Through the kindness of Mr. Joseph A. Clubb, Assistant 

 Curator, I spent several very pleasant hours in going over these col- 

 lections.
