barclayi, C. saul, two specimens of C. guttata, large suites of C. 
scottii, C. thersites, C. umbilicata and very large and handsome series

The collection of shells on exhibition in the Liverpool, or Derby 
Museum, as it is called, although not large, is exceptionally fine, and

Curator, [ spent several very pleasant hours in going over these col- 
lections.
