species seems amphibious. L. pahistris. — Bardowie and Frank- 

 field Loclis; extremely numerous in a ditch at the north-western 

 angle of the latter, on plants. L. glabra. — Frankfield Loch, mingled 

 with L. jmlustris and as numerous. Jeffreys says, " this shell is 

 sparingly distributed in this country," and gives no Scottish locality. 



Ancylus fluviatilis. — Common in rivulets and clear streams, 

 adhering to stones in the currents onhj; very large in Clyde in 

 the rapid opposite Dalbeth. A. lacustris. — I had very great 

 difficulty in procuring tliis shell, and latterly found a single 

 specimen in Bishop Loch. Since then I have gathered them 

 in quantities in the Forth and Clyde Canal at Old Kilpatrick. 

 They are said to be found principally on the under side of the 

 leaves of the water lily, but they seem to prefer the blades of 

 the iris, and are found at their lower part. 



Limax maximus. — The largest of the slugs has its shell internal, 

 which requires to be dissected from beneath the mantle. The best 

 situations for this species are beneath blocks of decaying wood 

 in damp places, where they will often be found five or six inches 

 in length. 



Succima jndris. — This species is found adhering to the dry 

 parts of stones in stagnant water, and is very generally distributed. 

 Old lade, Dalmuir; upper part of Gorbals Gravitation Water 

 Works, etc. 



Vitrina pellucida. — Corrieburn, Campsie Glen, and such places, 

 beneath stones and among decaying leaves. I have never found 

 the live specimens of this shell nearly so large nor so numerous as 

 the dead ones. 



Zonites cellaria, Z. alliaria. — It would be difficult to mention a 

 place where there is vegetation in which some one or both of these 

 species are not found. They seem gross feeders, and capable of 

 living under very adverse conditions, even amongst the smoke and 

 dust of the city, there being specimens in the collection from the 

 College Green. They are found under stones, on old walls, and 

 pieces of decaying wood. Z. radiatulus. — Calderwood Glen ; very 

 plentiful in small glen in Cadzow Forest; roots of moss and decaying 

 leaves. Z. crystaUinus. — North Hill, Campsie; East Kilbride, 

 Bothwell Castle, Auchentorlie Glen, etc. Amongst dead leaves, 

 roots of grass, and under stones. Z. fidvus. — Old limestone quar- 

 ries. East Kilbride; Barncluith Gardens, Hamilton; Auchentorlie 

 Glen. Under decaying wood, leaves, stones, etc.
