278 The Irish Naturalist. September, 



Hyallnla cellar ia. Mull — Generally distributed throughout the 

 district — Bally phehane, Glendiiie, Ardsallagh, Carrigrohane, 

 Blarney, Aghada, and Rostellan. All specimens taken were of a 

 large highly-polished form, with dark-blue animals, and therefore 

 not typical Hyalinia cellaria, Mull, 



Hy. Di*aparnaudi,B eck. — Sparingly around old buildings, as the 

 church at Youghal (W. H. Patterson), and that at Aghada. Also 

 taken at Carrigrohane (Milne) and Ballyphehane. 



Hy. sp.? — A very polished species belonging to this genus, having a 

 highish spire and a narrow umbilicus, was taken in several 

 localities. As it did not seem to us to be referable to either 

 Hy. cellaria or Hy. Draparnaudi, we sent the specimens to Mr. A. S. 

 Kennard, F.G.S., who has been making a special study of this 

 group, both recent and fossil, and we give below an extract from his 

 letter. " This species is represented from Ballinspittal, Youghal, 

 and Carrigrohane, and I am unable to identify it with any recorded 

 British species. It is near to Vitrea Roger si, B. B. W., but it is cer- 

 tainly not that form ; neither is it V. helvetica, Blum., of which I 

 possess an original specimen. It is possible that it is V. subglabra, 

 Bourg. I have not seen this species, but, judging from the figure, 

 it is very near to the Irish shell. Mr. J. "W. Taylor, however, con- 

 siders V. subglabra as a synonym of V. lua'da, Drap. {Hyalinia 

 Draparnaadi, Beck.), but the Irish shell is certainly not the latter 

 species. Under these circumstances, it is perhaps better to list for 

 the present as Vitrea sp. ?" It is possible that this is the shell which 

 has been listed from various Irish localities under the names of 

 Hyalinia glabra and Hy. helvetica. 



Hy. alliaria, Miller.— Frequent, but nowhere common. The var 

 viridula was found oftener than the type. Ballyphehane, Glendiue 

 Blarney (var. viridula), Rostellan, Kinsale, Ballinspittal, and 

 Gouganebarra (var. viridula). 



Hy. nitldula, Drap.— Occurred, but not commonly, in all the old 

 wooded areas. The var. helmi was seen only at Ballyphehane 

 (Standen). The type was found at Ardsallagh, Rostellan, and 

 Gouganebarra. 



Hy. pura, Alder.— Rather rarer than any of the preceding species of 

 the genus, Ardsallagh (var. nitidosa, and type), and The Gearagh 

 being the only two localities in which it was recorded. 



Hy. radlatula, Alder.— Like the last species, this was not common, 

 but both the type and var. viridescenti-alba were taken at Glendine, 

 The Gearagh, Lough Allua, Carrigrohane, Rostellan, and Ballin- 

 spittal. 



Hy. crystallina, Mull.— Generally distributed and common— Glen- 

 dine, The Gearagh, Lough Allua, Blarney (var. contracta), Ballin- 

 spittal, and Gouganebarra. This shell showed great variation, and 

 two very distinct forms were noted— a small type, and a much 

 larger and more expanded form. The colour of the latter seemed
