The Irish Naturalist. 



Novemlper, 



Testacella haliotidea I found in November, igi8, among vine roots in 

 the garden of Derryvolgie House, Malone Road, Belfast. There is quite a 

 large colony there, and I have obtained a considerable number this year. 

 The specimens have been verified by Dr. Scharff, who tells me that this 

 is the most northerly record in Ireland. I suppose the species has been 

 introduced. 



When in Bundoran in 19 16, where so many extraordinary forms of 

 H. nemoralis have been found, I came across a specimen weighing 42 grains, 

 very much hea . icr than the usual examples, 



E. FoRSTER Green. 



Bootham School, York. 



A-lthough unknown to William Thompson from Co. Antrim, Helicella 

 intersecta has now proved to be widely distributed round the Antrim 

 coast, though it is still unknown from that of Down, To Mr. Forster 

 Green's stations given above may be added Bush Bay ; the old chalk 

 quarry at Ballycastle ; the old quarry near the tunnel at Red Bay ; and 

 the slopes of the Little Deer Park at Glenarm. I have also taken one very 

 large dead shell on the dunes at Red Bay, but have not seen it there alive. 



Like Mr. Green, I think that Helix hortensis occurs more commonly 

 than is known in the Downpatrick district of Co. Down, as I took a single 

 shell under a stone below the waterworks on the other side of the town 

 from the cathedral in 1899, while to the late J. N. Milne's station on Mahee 

 Island I can add as a habitat the neighbouring Reagh Island, The western 

 shore and islands of Strangford Lough have never been carefully worked. 

 In Co, Antrim also H. hortensis is probably more widely spread in the Braid 

 Valley than we suspect, as besides the single specimen taken by Mr, 

 Jackson near the northern base of Slemish (somewhere near the farm), I 

 have found the species fairly plentiful round the ruins of Skerry Church, a 

 few miles away across the valley. Only the fine banded yellow form has 

 been seen in Co. Antrim ; in Co. Derry (at Downhill) only the bandless 

 yellow one ; but in Co. Down both these varieties occur. 



Before recording this species care should always bs taken that the 

 " darts " have been removed from the animal and examined, as they are 

 the only absolute guarantee that the shell is not a white lipped form of the 

 common H. niemoralis. 



Likewise is Pyramidula rupestris more generally distributed along tlie 

 Chalk scarps of the Antrim coast than was formerly suppressed. Indeed 

 from Island Magee (S. of Hill's Port) to the northern face of Lurigethan 

 overlooking Cushendall, I have found it to occur on almost all the natui"ally 

 expDsed surfaces of the Cretaceous rocks. I have also taken it on a wall 

 built of basalt near the Sallagh Braes. Thompson's record from Scrabo, 

 Co. Down, has never b3en verified. According to my reading of the MS. 

 only a single specimen was taken " on a piece of sandstone " in the great 

 quarry, and I suspect soma error of identification. 



Other records I have come to regard as doubtful arc those of Vertigo 

 alpestris for Derry and Antrim, Last year I had an opportunity of
