and a "wheen buckies " with mottled or banded shells, are 

 apparently the sole terrestial representatives of the numerous 

 " shell fish " that are found in the sea, but to him who knows 

 how to use his eyes, our gardens and fields, woods and rocks, 

 rivers and lakes, have numerous molluscous inhabitants. To 

 assist, therefore, those who are desirous of becoming better 

 acquainted with our Scottish species, I have briefly noticed the 

 special localities affected by each. 



Arion ater L. — Appears to be common everywhere, though, 

 if the testimony of certain farmers is to be believed, less com- 

 mon than formerly, owing probably to the more extensive 

 drainage of the land. I have seen specimens not unfrequently 

 over 3000 feet above sea level. This animal varies consider- 

 ably • in colour : I have found, but rarely, specimens nearly 

 white. It is decidedly carnivorous, as well as herbivorous; I 

 once found one devouring a specimen of that common moth, 

 Spilosoma menthastri. 



A. hortensis Fer. — Common everywhere, and ascends as 

 high as A. ater. 



A.flavus Miill. — Is considered by some authors as merely 

 a variety of the last It is said to be common everywhere and 

 to be a more tender species than hortensis. 



Limax gagates Drap. — Is said to have occurred once, in the 

 west of Scotland. 



L. agrestis L. (nee Drap.) — Too common everywhere. 



L. marginatus Miill. — Is not an uncommon species through- 

 out the country. It may be found on trees, especially beech, 

 on the trunks of which it may often be seen in abundance 

 after rain. It is occasionally, however, to be found on rocks, 

 as, for example, on Ben Lawers, where it ascends more than 

 3000 feet above sea level. Like some others of the genus, 

 L. marginatus is attracted by the "sugar" put on trees by 

 collectors of moths. 



L. Icevis Miill. (brunneus Drap. ?) — Mr. Jeffreys says that this 

 species is common everywhere. (British Conchology, v., 156.) 



L. tenellus Miill. — " North Marine, Shetland" Jeffreys (/. e. 



v., i5 6 )- 



L. flavus L. — Common; usually in or near houses, inhabiting 



sculleries and damp cellars. It is more rarely found in woods. 



L. maximus L. — Not uncommon in the same places as the 



last, but more frequently found in woods, often ascending trees
