Stelfox — List of Land and Freshwater Moll2islcs of Ireland. 133 



H. nitidula Drap. — A large form referaljle to the var. nitens hafs Ijeen 

 introduced with other species on to the railway near Magheramorne, in 

 Antrim. 



Zonitoides minusculus Binnej". — Common in the hot-honses at the Botanic 

 Park in Belfast. 



Genercd Distribution. — North America. 



Zonitoides sp. — Mr. Phillips has recently found at Glasnevin a single 

 example of a shell resemlaling a small Z. nitidus. On comparing this with 

 a shell taken by myself or Mr. Welch at Ci'awford's Nursery, in Belfast, in 

 1907, I find that they are identical. Mr. Welch and I had, at the time it was 

 found, passed the Belfast specimen over as a peculiar form of Z. nitidus ; but 

 after seeing that collected by Mr. Phillips I have no doubt that both must be 

 referred to some foreign species. This shell resembles Hyalinia arborea Say, 

 and also K. pdronelta Charp. ; but is distinguished fro-m the latter by its closer 

 striae, and from the former by its narrower whorls. Prom Z. excavatiis it is 

 at once distinguished by its narrower umbilicus, though, when viewed from 

 above, it closely resembles that species. 



Patulastra flavida Ziegler. — Fairly common in some of tlie houses at Glas- 

 nevin. This shell is easily kept in captivity; and I have now (December, 1910) 

 quite a number of half-grown examples, the progeny of two specimens brought 

 from Glasne^^n in February of the present year. 



General Distribidion. — Southern Europe, including some of the Mediter- 

 ranean Isles. 



Helicodiscus lineatus Say. — First taken by Mr. Phillips in the hot-houses 

 at University College, Cork, and since found at Glasnevin and Castlewellan. 



General Distribution. — North America. 



Helicella virgata Da Costa. — A large and very high-spired form of this 

 shell has been introduced (with ballast ?) on the Midland Eailway near 

 Magheramorne, in Antrim, together with other species. 



H. intersecta Poiret. — With H. virgata. 



H. cantiana Mont. — There are specimens of this shell in the Dublin 

 Museum from Stillorgan Park, Co. Dublin ; but whether it has estabUshed 

 itself there or not I cannot say. It has also been introduced at Tivoli, near 

 Cork, and seems to have become quite naturalized. (Irish Nat., Jan. 1911). 



General Distribution. — Central Europe and southern Britain. 



H. cartusiana ]Mull. Imported into Belfast with cxirrants from Turkey. 



General Distribution. — Widely distributed in the southern lialf of Europe, 

 and also found in the south-east corner of England. 



H. pyramidalis {I = H. xnjramidata Drap.). — Piecorded by Mr. Green as 

 imported with raisins into Belfast. 



General Distribution, — Mediterranean littoral,
