White Variety of Black Slug in Stirlingshire. — I recently 

 received from the late Dr Harvie-Brown a fine example of Arion 

 ater var. alba, subvar. margi/iata, sent to him by Mr James Dick 

 of Burnside, Kippen, found at that place. The white form of this 

 species seems to be rare. The only Scottish examples I have seen 

 are one of subvar. iiiarginata, taken at Uddingston, Lanarkshire, 

 June 1889, by Mr Alex. Shaw, and one of which the subvar. was 

 not noted, from North Esk, near Morphie, Kincardineshire, found 

 by Mr W. Duncan in May 1891. My own record of subvar. elegans 

 in the yard of Thornielee Railway Station, Selkirkshire, August 1886, 

 is an error, the species being the small Arion intermedius ; the error 

 is excusable, inasmuch as the latter species was not added to the 

 British list till some years later, but my note of the find was 

 sufficiently explicit and detailed to leave no doubt as to the correct 

 specific identification. 



Stirlingshire is one of the counties for which I propose to write 

 a list for publication in this journal : I shall therefore be pleased to 

 see any specimens of MoUusca that may be sent to me with the view 

 of making it more complete. — W. Denison Roebuck, 259 Hyde
