 Arion nter var. scharffi Cockerell, Journ. of Mai., 1893, p. 208. 



Animal deep brown, with sides of body yellowish or orange. 



The sub-var. seharffl differs in the back beiu};- black instead of deep brown, 

 sides yellow, and according to Prof. Cockerell his var. elhirolata is ahiiost identical. 



The Arion riifus var. himlin- of jMoquin-Tandon, judging by ligs. 6, 7, on plate 1 

 of F(iru.ssac's work, which he cites as repre.senting his form, is not this species, but 

 Avion .'iulif use us. Mr. Roebuck first correctly used the name i/cofor in connection 

 with the present species. 



Like the var. alhnlatevali.f, this vaiiety would seem in this country to be stiictly 

 westei'u in its <listribution, M'hile Dr. Scliarif has expressed the opinion that, 

 according to his experience in Ireland, it is a strictly littoral form in that country, 

 and states that Siniroth has found similar specimens on the shores of the Baltic Sea.
