Grenerally distiibuted and usually 

 common in damp and shady places. The 

 typical form, as known to most Englisli 

 authors, is, I think, found more often 

 than elsewhere in the south and mid- 

 lands. Specimens from Carrigrohane, 

 Mid Cork, seem to be identical with the 

 Hyalinia suhterranea of Bourguignat. 

 The smaller and more contracted form, 

 Hyalinia contraota of Westerlund, is 

 perhaps more widely distributed ; but 

 as it is diificult to separate these two 

 forms, except in the case of well- 

 marked specimens, their distribution 

 cannot at present be clearly shown. 

 Generally found on the western and 

 other islands, but not common on any. 



Hyalinia lucida (Draparnaud). 



Hyah 



Draparnaudi, Soharff, Irish 

 Nat., p. 65, 1892. 



From its distribution in Ireland, 

 which is similar to that of the Testa- 



(Mon. L. and F. W. Moll, of the Brit. Isles, 

 Vol. Ill, appendix), it may be of interest to 

 mention ihat there are specimens of this shell in 

 the Dublin Museum, collected by Dr. Sdiarff 



cellidue, this is a most interesting 

 species. It is, moreover, the only one

of its genus that is not generally dis- 

 tributed in this country. In many places 

 in Munster and in parts of Leinster it 

 sometimes outnumbers all the other 

 Hyaliniae, especially in towns and in tlie 

 neighbourhood of habitations. Outside 

 these areas we have no authentic records. 

 Large specimens of our Irish Hyalinia 

 cellaria ( Vitrea hilerniea Kennard) 

 have f rec^uently been mistaken for this 

 species ; and we have therefore many 

 false records to contend with. Thus, 

 H. lucida has been recorded from the 

 Aran Islands in Clare, South Kerry, 

 West Cork, West Gal way, N.E. Galway, 

 Leitrim, Cavan, West Donegal, East 

 Donegal, Antrim, and Down ; but the 

 majority of these areas have been since 

 visited by conohologists who found 

 nothing but the large race of H. cellaria 

 mentioned above. Therefore until re- 

 found, it would be unwise to record it 

 for any of the divisions mentioned. 

 H. lucida has been introduced with 

 plants into hot-houses in Cork, Dublin. 

 Antrim, Down, and Fermanagh, &c. 



some years ago at Eaux lionnes, Ferussac's 

 original habitat for tl;e species. These appear 

 to be iilmost identical with specimens of the 

 Irisli shell from Co. Louth.
