Vitrina pellucida
Vitrina pellucida is species of small land snail, a terrestrial pulmonate gastropod mollusk in the family Vitrinidae, the glass snails. Description

This species is a 'semi-slug' with a flattened, globular shell. The animal is pale grey with darker head and tentacles. It is large in comparison with the shell, and cannot completely retreat into it. The shell is subglobose, somewhat smooth, pellucid and greenish hyaline in colour. The shell has 3 whorls that enlarge rapidly and are somewhat convex. The body whorl is wide and a little flattened below. The suture is wrinkled. The aperture is lunately rounded. The umbilicus is very small. The width of the shell is 6 mm, the height is 3.5 mm. Distribution 

This species is known to occur in a number of countries and islands in Western Europe and Central Europe, including:

 Bulgaria
 Czech Republic
 Netherlands
 Poland
 Slovakia
 Ukraine
 Great Britain
 Ireland
 and other areas

These snails occur both in natural and modified habitats, such as in meadows and grasslands, in deciduous and coniferous forests, and in wasteground. Eggs: The eggs are deposited in small heaps, and have a membraneous covering. Parasites of Vitrina pellucida include:
