The Irish La7id and Freshwater Mollusca. 67 



Hyalinia contracta, West. 



This species is new to the British Fauna. The specimen which I 

 obtained at Killarney is more like that described by Clessin as H. 

 dubreuili, but, as Mr. B. B. Woodward has pointed out to me, the latter 

 is probably only a variety of H. contracta, and it is considered as such by 

 Dr. Westerlund. It differs from //. crystallina in having one more whorl, 

 and in the two last being equal in breadth, instead of the outer one 

 being considerably broader. 



Foreign Distribution. — Sweden, Norway, Northern Germany, 

 France, and Switzerland. 



Hyalinia fulva, Miiller. 

 I. — — IV. V. — VII. VIII. IX. X. — XII. 



By many authorities this species is placed in a separate genus 

 Conulus, as its form differs so much from the general type of the Hya- 

 linia;. To judge from the large number of specimens obtained by Mr. 

 Praeger in the Co. Dowm, it must be pretty common there, but about 

 Dublin it is extremely rare. 



Foreign Distribution. — Like H. radiatula, this species has a very 

 wide distribution, ranging over the whole of E)urope, Northern Africa, 

 the Azores, Siberia, and North America. 



Hyalinia excavata, Bean. 

 I. — — — V..? — — VIII. — — — — 



On the south-west and west coast this species is fairly common, espe- 

 cially in Connemara, but it is evidently quite absent from the east coast, 

 as neither my predecessors, Messrs. Warren and Thompson, nor myself, 

 have ever found it, and the record from Dublin in Messrs. Ta3dor and 

 Roebuck's list is, I venture to think, erroneous. By many Continental 

 authorities this species, along with the next, is placed in a separate 

 genus Zonitoides. 



Foreign Distribution. — Beyond Great Britain this species has only 

 been found at a single locality — viz., Flensburg, in Northern Germany, 

 and I think it is possible that, like U. alliaria, it may have originated in 

 the British islands. 



Hyalinia nitida, Miiller. 

 I. II. III. IV. V. — VII. VIII. IX. X. — XII. 



This is H. lucida, Drap, and, as Thompson has already mentioned 

 it is a very rare species in Ireland. He has recorded it from Kilmegan 

 Bog (Down), Portarlington (Queen's Co.), and Finnoe (Tipperary), while 

 Miss Warren has kindly supplied me with speciemens from Co. Sligo. It 

 has also been found at Rathfarnham, and I myself, obtained a dead 

 specimen at Stepaside (Dublin). 



Foreign Distribution. — This species has an enormous range, occur- 

 ring over the whole of Kurope, Algeria, Thibet, Turkestan, Siberia, Japan, 

 and North America.
