GASTROPODA. 



PULMONATA, 



Genus— VITBINA. 



Vitrina pellucida, Muller. 



— II. — IV. V. VI. VII. VIII. IX. X. — XII. 



This species is fairly common in most parts of the mainland, and I 

 recently found it also on the Aran Islands, Co. Galway. As a rule only 

 dead shells are seen during summer, and it should be looked for during 

 the winter months, when it is most active. Some of the specimens I 

 have seen resembled Vitrina Major, Fer., which occurs in the south of 

 France. 



Foreign Distribution. — Common in Great Britain. To judge from 

 its distribution, it must be one of our oldest living land-shells, for it has 

 also been found all over central and northern Europe, the Caucasus and 

 Siberia, and very closely allied species live in North America and Green- 

 land.
