AEION HORTENSIS. 219 



Geographical Distribution. — A . korfensis being the most advanced 

 and most recently evolved species of its special section, has not yet attained 

 a wide dispersal, being confined naturally to Central Europe, where it 

 abounds more especially on cultivated lands. From its close association 

 with cultivation it is liable to be transported to other regions, where its 

 high and plastic organization almost ensure its dominancy. 



It is found throughout the British Isles, chiefly congregating in gardens 

 and on tilled ground, but is also found on wooded and waste lands far from 

 cultivation. 



The recorded continental distribution is not reliable, as this species has 

 doubtless frequently been confounded with Arion ciraimscripttis, a closely- 

 allied but more ancient and widely-dispersed species, from whicli it has 

 only in recent years been authoritatively and satisfactorily distinguished.
