 var. tindulata, from Southport, and mounted darts of twelve species of 

 Helicidse.

 from the Isle of Wight, Rottingdean, Sussex, and from Staffordshire ; the 

 collection included Helix cantiaiia, Helix virgata, and varieties, Pupa 

 zinibilicata, and Cyclostoina elegans, from Brading ; Helix hortensis, from 

 Bembridge ; Paludina vivipara, Richmond-on-Thames ; Helix ericetortim

 ralis, Helix hortensis, Helix arbustoriun. Helix virgata, and Helix erice-
