i9°7- Taylor.— Vitrina elongata in Ireland. 23 1 



that both our species are found in the Pleistocene beds of 

 Franconia. 



The geographical distribution of V. elongata shows it to be 

 confined on the Continent to the alpine regions, being 

 recorded for South Germany, Switzerland, Hungary, Tran- 

 sylvania, TjtoI, North Italy, South France, Eastern Pyrenees, 

 Spain and other countries, attaining in many places an 

 altitude of 8,000 feet. 



It is to Mr. P. H. Grierson, of Dublin, whose energy and 

 success in aiding in the elucidation of the fauna of Ireland is 

 so well known, that we are indebted for the discovery of this 

 very distinct species, inasmuch as amongst the shells sent for 

 examination and authentication were a number of specimens 

 of this species, which he had found plentifully in September, 

 1904, and June, 1905, near Collon, in County Louth. 



It is to be hoped that as attention is now directed to this 

 species, other localities will soon be found for it in this 

 country, as our greatest fear in bringing this waning form 

 into prominence is the risk of its extermination if the ground 

 be over-collected; as even if other stations be found, it would 

 be a matter of regret if the first known station were destroyed.
