CON TINENT. AL DISTRIBUTION. 
Norway—Sub-var. media, Bergen (Miss Esmark, J. of Conch., Oct. 1886). 
Var. bicolor Roebuck, not of Moq.-l'and., Hist. Moll. France, 1854, p. 11. 
Arion ater var. elincolatus Cockerell, Science Gossip, Nov. 1886, p. 259. 
Arion ater var. scharffi Cockerell, Journ. of Mal., 1893, p. 208. 
ANIMAL deep brown, with sides of body yellowish or orange. 
The sub-var. seharffi differs in the back being black instead of deep brown, 
sides yellow, and according to Prof. Cockerell his var. e/ineo/ata is almost identical. 
The Arion rufus var. bicolor of Moquin-Tandon, judging by figs. 6, 7, on plate 1 
of Férussae’s work, which he cites as representing his form, is not this species, but 
Arion subfuscus. Mr. Roebuck first correctly used the name bico/or in connection 
with the present species. 
Like the var. a/bolateralis, this variety would seem in this country to be strictly 
western in its distribution, while Dr. Scharff has expressed the opinion that, 
according to his experience in Ireland, it is a strictly littoral form in that country, 
and states that Simroth has found similar specimens on the shores of the Baltic Sea.
