L. Sowerbii is common in gardens and shadj 
places in the vicinity of most of the cities and 
towns of the South; Sandown, Isle of Wight; 
Norwich; Chester; becoming rare northwards. 
In Ireland, Cork, Dublin, Youghal, and Gal¬

Spain. 
They feed on cabbages and other vegetables, 
when in a more or less decayed condition, are 
very destructive to the celery and bulbs under 
ground. They are foul feeders, and, like other 
slugs, have a decided liking to animal matter, 
devouring the dead remains of each other, and 
not refusing carrion: they have been observed

The eggs are oval, soft, elastic, two-tenths of an
