192 ARION ATER. 
SWITZERLAND. 
Recorded or known to exist in the cantons of Berne, Grisons, Lucerne, Neuchatel, 
St. Gall, Solothurn, Schwytz, Ticino, Unterwalden, Uri, Vaud, and Zurich. 
RUSSTA. 
A. ater has been recorded from Finland by Heynemann; Courland by Kawall 
and Braun; Livland by Kawall; Esthland by Eichwald ; Moscow by Nadjeschin ; 
and as tolerably common in the woods of Tchernigov, Kharkov, and Poltava, by 
Kaleniezenko, who also gives precise localities for many of the varieties figured or 
described by Férussac, but Dr. Simroth, after an exhaustive investigation, totally 
denies the existence of A. afer in Russia, but it is very probable that it does really 
exist in the most western of the Baltic provinces. 
Siberia—Gerstfeldt erroneously records A. ater from Wilni, Irkutsch. 
NORTH AFRICA, ASIA MINOR, Ete. 
Algeria—Recorded as Arion rufus by Aucapitaine, but probably more correctly 
referable to Avion lusitanicus or other form of the subfuscus group. 
ATLANTIC ISLES. 
Reported from the Azores, Madeira, and Canary Isles, but Dr. Simroth says the 
species occurring there are A. /usitanicus and its allies. 
NEARCTIC REGION. 
United States—Grateloup, in 1855, records Arion empiricormm as found in the 
Western States, but this is not confirmed by more recent authors. 
AUSTRALASIAN REGION. 
New Zealand—Recorded for Dunedin by Hutton, and by Musson as found 
crawling about after rain over the roads around Auckland, 
Fic. 207.—Typical habitat of Axon ater var. aterrima, at an altitude of 2,500 feet
