slightly more yellow. The umbilicus is somewhat 

 large, and immediately around it the colour is opaque 

 white. The opening of the shell differs from that of 

 Zonites cellarius in being not so opaque. 



The form of the animal bears a striking resemblance 

 to the cellar snail, but the colour is different, being a 

 blue black. The tentacles are small. The size of the 

 shell is a quarter of an inch in diameter. 



There are several varieties, one of which grows to a 

 larger size, and the distinctive character of another is 

 in the colour being a greenish tint. 



The name "Garlic Snail," is applied to this species 

 because some of them have a strong garlic scent when 

 alive, whilst others, not possessing this scent when 

 alive, have it in a powerful degree on being destroyed 

 in hot water, arising trom the secretion of a scented 

 mucus. The garlic scent is not, however, confined to 

 this snail, as occasionally other branches of the Helix 

 family have been found to possess it. 



An inhabitant of woods, gardens, wet banks, and even 

 in greenhouses. It is mostly found under stones, 

 amongst decayed leaves, and at the roots of long grass. 

 It occurs even at the summits of mountains.

 traordinary numbers, at Thrumpton, and at Highfield 

 House.
