Marcii, 
A new station for Helix virgata. 
While collecting near Magheraniourue on January 13 this year, we dis- 
covered a very local but numerous colon)'' of this species, on the railway 
embankment, about a quarter of a mile north of Magheramourne 
station, along with H. caperata and H. riifesceiis. It is probable that two of 
these three species have been introduced with ballast, and one of the 
railway employees informed us that he remembered ballasting this par- 
ticular portion of the line with gravel that came from a ship at Larne. 
Neither H. virgata nor H. rtifescens seem to have spread from the railway, 
but this cannot be said of H. caperata, as H. L. Orr and J. N. Milne have 
both taken it previously on the old quarry tip, and J. N. Milne has also 
taken it, two years ago, above the present quarr}^ fully half a mile from 
the colony. We, ourselves, on 13 January, took a few specimens where 
the quarry tramway runs under the count}' road. From this it seems to 
us just possible that there may have been an original colony of //. caperata 
there. The H. vh'gata are very different from the Ballycastle, North 
Antrim, form, much higher in the spire, and more varied in colour and 
markings.

Mr. B. vSt. G. Lefroy sends me the following species from Termonbarry

between, these are welcome towards future county lists : — Limax inaximiis^ 
L. inarginatus, Agrioliniax agrestis^ Limuica percgra, Planorbis carinattis, P. 
vortex, Bythinia tentaculata, Ncritina Jluviatilis, Sphceritun corneiim^ Pisidium

Hock Pipit at Sea. 
On Monday, 22nd January last, when crossing from Dublin to Holyhead, 
I noticed a small bird flitting over the waves towards the steamer. As it 
came quite close to the boat it raised its flight, and, reaching the^ rig- 
ging, it alighted for a short time on one of the ropes. After a couple 
of minutes it flew off. It was strong on the wing. When it came on 
board we were about eight miles from the South Stack lighthouse. To 
the best of my belief the bird was a Rock Pipit {An/hus obsainis), but as I 
had not my field glass with me, and I was only permitted a very short 
time to make observation, I will not state dogmatically that it was not 
Anthtis prateiists, or even a rare species.
