NOTES AND QUERIES. 419 
and seem to me worthy of notice. ‘The Skellig,” writes Mr. Delap, “is 
an immense rock, 800 feet high, very steep and bare, and the water is very 
deep all round.” Referring also to Skellig, when sending some specimens 
of H. nemoralis, he added,—* How they live there beats me; the waves 
broke a quarter-inch plate glass in the lighthouse, and many of the shells I 
got were not so high. You will see they are all weathered.” A box of 
slugs was sent, but most unfortunately parted company with the label in 
the post, and was never afterwards seen. Mr. Delap writes, however, about 
them :—“ They are, I suppose, the most westerly slugs ever taken in the 
British Isles.” They included—* Arion ater, black, red, and grey; Limax 
agrestis, grey and white; L. arborum ? well marked, or L. maximus, young; 
and a very small white Avion.” The shells, which I have examined, are 
are as follows :—Hyalina alliaria, many specimens, nearly all of viridula 
form ; some few pale brown. Helix nemoralis, yellow, with band-formule 
1,345, 00000 (12845), and (123)45. H. rotundata, all rather flat. Pupa 
umbilicata, pale, and almost edentulate. Balea perversa, pale, and of 
simplex form. Clausilia rugosa, all somewhat whitened. From this account 
it appears that the main characteristic of these insular shells is a paucity 
of colouring-matter ; but it may well be imagined that this is rather due to 
the barreuness of the rock and its bleak aspect than to auy other cause. Of 
other Kerry shells, sent with the above, much might be written; but it 
must now suffice to mention a few of them. Hyalina excavata was sent 
from Ballycarberry Point on the mainland, while Glanlean Wood on 
Valentia produced the variety vitrina, as well as Vertigo edentula in some 
abundance. Pupa ringens (= anglica) of typical form was found at Bally- 
carberry, but Glanlean Wood and Beginnis (an island in Valentia harbour) 
produced the form pallida, Jef’. A curious form of Arion ater was sent 
from Valentia, being rather pale yellowish brown, back and mantle darker ; 
ill-marked brown lateral bands on body and mantle, and faint trace of dorsal 
band; mantle speckled ; fringes pale orange, without the usual dark 
lineoles. This variety is superficially not much unlike A. subfuscus, but 
is, neverthless, certainly a form of ater. From Beginnis were sent Vitrina 
pellucida, Hyalina cellaria, H. nitidula, H. radiatula type and viridescentti- 
alba, H. alliaria var. viridula, Helix rotundata and vars. turtoni and alba, 
H. hispida var., Pupa ringens v. pallida, P. marginata vy. edentula, 
P. umbilicata and var. sempronii (but with microscopical denticle), 
Cochlicopa lubrica, Pisidium pusillum, and a very curious little Hydrobia, 
8 mill. long, pale, with deepish suture, obscure brown marks at intervals 
on body whorl. This was found with the Pisidium in a locality where 
there was very little water. Iam ata loss to identify it with any species 
known as British hitherto. Of localities on the mainland, Karen Wood 
(Cahireween) produced Pisidium pulchellum and Cochlicopa lubrica var. 
Jusca; Finney (or Fermoyle) Bog contributed Linn@a truncatula and
