68 LIMAX CINEREO-NIGER. 
Geographical Distribution. — Limax cinereo-niger is widely and 
somewhat irregularly distributed, especially in the British Isles, and although 
the area occupied in continental Europe is fairly compact, the stations are 
usually more or less montane, and therefore to a large degree discontinuous, 
as it is frequently absent from the valleys and open grounds. 
Its north-European range has been carefully worked out with especial 
reference to that of Limaa mavimus, and it is found to extend markedly 
beyond that of the latter species. In Norway, Esmark & Hoyer have fore- 
shadowed its occurrence at Moskenaes, in Lofoten, 68° 6’ north latitude, 
while recording it as very common at Grito in Nordland, which is 67° 49’ 
north latitude, and far beyond the known range of habitation of Limar 
maximus. In Sweden, it has been chronicled by A. Luther as existing at 
Funasdal, in Hirjedal, 62° 30’ north latitude ; while in Finland, according 
to the same author, it is tolerably common in the south-west, and reaches 
as high as 64° 30’ north latitude at Kivesva: ira, In Paltamo, whereas L. mawi- 
mus in that country is restricted to the neighbourhood of Helsingfors. 
In the south of Europe, although a like discriminatory series of observa- 
tions is not available, Fischer records that in the Mae the Limar 
maximus only attains an altitude of 1,200 metres (about 3,930 feet), while 
the present species, according to Bourguignat, reaches in the same region 
almost to the snow-line.
