LIMAX CINEREO-NIGER. 



Geographical Distribution. — i^■»^ai^; 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 Umax maximus, 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 Groto in Nordland, which is 67° 49' 

 north latitude, and far beyond the known range of habitation of Limax 

 maximus. In Sweden, it has been chronicled by A. Luther as existing at 

 Funasdal, in Harjedal, 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 Kivesvaara, in Paltamo, whereas L. maxi- 

 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 Pyrenees the Limax 

 maximus only attains an altitude of 1,200 metres (about 3,930 feet), while 

 the present species, according to Bourguiguat, reaches in the same region 

 almost to the snow-line.
