 from the south-west corner of Ireland are darker and more strongly banded than 

 British specimens ; they are probably referable to the sub-var. mollerii.

Geographical Distribution. — The area iuliabited by this very 

 ancient species is doubtless more extensive than that of any of its con- 

 geners, but is as yet very inadequately known, as this Arhm has been, and 

 is still, so often passed over or mistaken for a jiale variety oi Arion horten^k 

 or the young state of A. afer, even by experienced conchologists, before its 

 specific peculiarities have been pointed out. In fact, our knowledge of the 

 distribution of the wliole of tlie species of the genus Arion is in a very 

 confused and unsatisfactory condition, owing chiefly to the neglect of the 

 group by most conchologists, and the lamentable ignorance on tlie subject 

 which so generally prevails. 



Arion intfnncdius has, however, been reported from Great Britain, 

 Germany, France, North Italy, Switzerland, Russia, iScandinavia, Portugal, 

 and the Azores. 



It is also plentiful in or near gardens in certain parts of New Zealand, 

 from whence it was first reported by Capt. Hiitton as Arion i}innnmochix.
