marsh by the river below Dungiven Abbey. NNN. 
Milax gagates, Drap. — By the old church at Tamlaght — typical form — 
and in refuse from the town by the river at Limavady — brown form. 
In the latter station its standing is *** ; but at Tamlaght Church 
it may be NN*. 
M. Sowerbyi, Fer. — Plentiful near Downhill Ry. Station (Welch, Febr., 
1900), Standing doubtful, probably ***. 
Vitrina pellucida, Miill. — Benevenagh, Magilhgan, Glens of Banagher, and 
Roe Park. No doubt common in winter. NNN. 
Hyalinia cellaria, Miill. — Not generally distributed and only common in 
the Glens of Banagher. Also recorded from Benady Glen, Tamlaght 
Old Church, and the escarpment at Umbra. All specimens may be 
referred to the usual large Irish form. NNN. 
H. alliaria, Miller. — Common in Tamlaght Woods and Walworth W^ood, 
also at Benevenagh and in the glens about Dungiven. NNN. 
H. nitidula, Drap. — Generally distributed. NNN. 
H. pura, Alder. — Also of general occurrence in the district. NNN.

Zonitoides excavatus, Bean. — Common in Walworth Wood — type and 
var. vitrina ; also in Roe Park, Limavady (Milne) — var. vitrina only. 
NNN. 
Euconulus fulvus, Mull. — Never abundant, but frequent about Dungiven, 
in Walworth Wood, and at Benevenagh, NNN. 
Arion ater, L. — Common. NNN. 
A. subfuscus, Drap. — Common. NNN. 
A. intermedius, Normand. — Common where found ; Benevenagh, Wal- 
worth Wood, and about Dungiven. NNN. 
A. hortensis, Fer. — Very common in some places about Dungiven, but 
appeared quite absent from neighbouring situations. Thus it was 
abundant in the Glens of Banagher and yet was not seen in Benady 
Glen, a few miles to the east. It occurred on Chalk south of Ben- 
bradagh, at an altitude of 1,200 feet. Also found at Limavady, 
Tamlaght, Roe Park, and Umbra. It is always with great satis- 
faction that I record this species as " undoubtedly native," since 
there are so many districts, especially in the west, where it has all 
the appearance of a recently imported ahen. NNN. 
A. circumscriptus, Johnst. — Of general occurrence in the district. NNN. 
Punctum pygmaeum, Drap. — In moss in Benady Glen. Common in Hood 
debris inside tiic " intake " at Limavady Junction (Welch, 1903).

Sphyradium edentulum, Drap. — Tamlaght Woods, Walworth Wood, and 
about Dungiven, apparently local. NNN.
