Vitrea cellaria (Miiller). 

 Vitrea alliaria (Miller). 



van viridula Jeff. 

 Vitrea nitidula (Drap.). 

 Vitrea pura (Alder). 

 var. nitidosa Gray. 

 Vitrea radiatula (Alder).— All the above occurred sparingly. 



var. viridescenti-alba Jeff. — Two specimens. 

 Zonitoides nitidus (Miiller). — Only noted in some swampy 

 ground close to the shore. 



Euconulus fulvus (Miiller). — Common. 

 Arion ater (L.). — Abundant. 



var. castanea Dum. & Mort. — Common, 

 var. bicolor Roebuck. — Several, but not quite characteristic. 

 var. aterrima 'laylor. — Not uncommon on Brandon Mountain 

 above 2,500 feet. "The blackest I have ever seen" (Roebuck). 

 Arion subfuscus (Drap.). — Common. 

 Arion circumscriptus Johnston. — Not common. 

 Punctum pygmaeum (Drap.). — A few in damp moss. 

 Sphyradium edentulum (Drap.). — Common, especially when 

 sweeping long, thick herbage with a strong net for coleoptera. My 

 experience everywhere is that 6'. edentulum is always the commonest 

 shell obtained in this manner. Sometimes it can be swept by scores. 

 Pyramidula rotundata (Miiller). — Very common. 

 Helicella itala (L.). 

 var. instabilis Zgl. 



var. leucozona Taylor. — A very abundant species on the sand- 

 hills, and invariably of the small, high-spired instabilis form, averaging 

 7 mm. in breadth. The commonest coloration is that of the var. 

 leucozona. 



Helicella caperata (Montagu). — Common, but small. 

 Hygromia hispida (L.). 

 var. hispidosa Mousson. 

 Hygromia rufescens (Pennant).

Vallonia COStata (Miiller). — Both these forms were scarce, and 

 only occurred in the damp ground near the shore. 

 Helix aspersa (Miiller). — Common. 



var. tenuior Shuttleworth. — Rather common on the sandhills 

 near Brandon. 



var. conoidea Picard. — By no means uncommon at Brandon, 

 var. nigrescens Moq. — One specimen.
