LIMAX ARBORUM. 97 
Geographical Distribution.—Limax arborum is an ancient species, 
and therefore has a very wide distribution, and is found from the extreme 
north of Lapland and Iceland to Orotava in ‘Teneriffe; and according to 
Schartf, has probably been extending its area of habitation since early 
tertiary times, but its range is probably very imperfectly known, as it is so 
frequently confused with Z. maximus and other species. 
It has been reported from the British Isles, Germany, Belgium, Holland, 
France, Spain, Portugal, Switzerland, Austro-Hungary, Italy, Greece, Den- 
mark, Norway, Sweden, and Russia. 
In the British Isles Z. arborum is in all likelihood universally dispersed 
and the gaps at present shown in its range will probably be filled up as the 
species becomes better known.
