198 The Irish Naturalists' Journal. [Vol. III.

it was living in myriads in little brackish pools on the edge of the Bann,

just above ordinary high tide mark, near the river mouth. I had already found it dead in shell

" pockets

*' in 1893, in the dunes not far from the

pools, and on the 1897 visit I also found it dead as a flood tide mark, from

which it was evidently blown into the dune hollows, with a few small

freshwater and marine shells. Its presence in the dunes and pools here, so soon after its discovery in the Thames, was very interesting, but later in the same year (1897), while collecting in the wide area of sand dunes

east of the golf links at Portrush, I found a large number of it, not long dead, with small Limnma truncatula, in a very small dried-up pool in a

dune hollow well inland from the sea, with no stream near by and miles

away from the Bann at Portstewart. So far it has never occurred in the two streams at Portrush; how did it get into the dune-pool only four or five feet in diameter? Personally, I think this shell may really be

Pfeiffer's Pahidina crystalUna, originally a West Indian species.

TIDAL FRINGE OF LAXDSHKLLS, CO. WICKLOW.

In .the Irish Naturalist, vol. 12, February, 1903, pp. 53-54, I gave a

list of shells, etc., I had seen forming tidal fringes on various parts of the coast in Ireland. On February this year, while visiting the Murrough of

Wicklow, just north of Newcastle, I found along the tidal inlet, inside of the railway, very large numbers of Helicella virgata and //. barbara, with a few Hygroniia hispida. with a few Helix aspersa, all in a thick mass.of

vegetable debris swept off the grassy area by

an unusually high tide during the storm that played such havoc with villas at Greystones, a few miles farther north. Large numbers of the Helix were hibernating in cavities

of old decaying sleepers forming the posts for the wire fencing for the

railway. I took ten, all attached as usual, out of one cavity. Here they had no protection from rain whatever, as the hole opened from the top of the sleeper. As a rule this species very carefully selects for hibernation a locality where it can be dry during that period. Here it had no alterna tive but the old sleepers.

NUDIBRANCH RECORDS FROM N.E. IRELAND.

There are so few records of even the commonest Nudihrancbs from N.E. Ireland that the following may be of interest :?

Gal vino exigua (Alder & Hancock). In Hyndman's copy of Thompson's " Fauna of Ireland : Div. Invertebrata

" is this pencilled note :

" Eolis

exigua 1 Off Copelands, in 35 fathoms, Sept.. 1851. Compared with Alder & Hancock's figure and seems identical except that reddish markings were on the head of mine not represented in A. & H.'s figure."

Facelina drummondi (Thompson). In old pholas burrows between tide

marks, Greenisland, Co. Antrim, 1925, etc. (N.F.) Lomanotus genei Verany. A specimen was dredged in 15 fathoms 4

miles off Black H'ead, toward the Copelands, Sept. 13th, 1858. (Hvndman, Brit. Ass. Report, 1858, p. 291.)

Doto fragilis (Forbes). A specimen was dredged off Whitehead in 10-12

fathoms, Aug. 13th, 1853. (Hvndman unpublished MS. notes.) Archidoris tuberculata (Cuvier). Between tidemarks, Greenisland, Co.

Antrim, 1925 (N.F.); Larne, near Chaine's memorial, spawning, plentiful, March, 1926 (N.F. & R. J. Welch); Orlock Point, Co. Down (R. J. Welch).

Acanthodoris pilosa (Muller). Larne Lough, 8th October, 1853. W.

Darragh. (Hyndman unpublished MiSS. notes.) Goniodoris nodosa (Montagu). A specimen from Ballintoy, Co. Antrim,

was sent to me by the Rev. E. M. Gumley in April, 1931. New to Co.

Antrim and previously only once recorded (by Drummond, fi.de Thompson, about 100 years ago) from N.E. Ireland.

Galvina exigua (if correct), Lomanotus genei, and Doto fragilis are all new to N.E. Ireland (Nichols' District 1).
