It is decidedly rare in some parts of tlie 

 west, and very rare on the Dingh^ 

 peninsula, ilr. Phillips tells me tliat 

 " in the soutliern half of Ireland, thougli 

 widespread, it is never abundant, and 

 a day's general sliell-collecting seldom 

 produces more than half a dozen 

 specimens." It is a shell that varies 

 con-siderably in shape; and in colour 

 it ranges from amber-yellow to bright 

 green. I have noticed the yellow- 

 coloured shells more often in the late 

 autumn months than in the spring ; and 

 they usually seem smaller and nioie 

 rounded than the green ones. This 

 species lives, though apparently rare, 

 on tlie majority of the western islands, 

 and is also recorded from Lambay in 

 Dublin, andRathlin in Antrim.

space of time since its discoveiy by 

 Mr. Grierson, given rise to much con- 

 troversy. Mr. Taylor in 1907, described 

 it as Vitrinaelongata Urap., after it had 

 been recorded by Mr. Grierson as 

 Vitrina pellucida, var. depressiuscula : 

 the Rev. E. W. Bowell, having dissected 

 the animal, pronounced it to be identical 

 with Ferussac's Vitrina pyrenaica, and 

 iinally in his Monograph^ Mr. Taylor 

 has accorded it new specitic rank. That 

 it is closely allied to, if not identical 

 with, the Tyrenean shell, there can bo 

 little doubt; but, until further con- 

 firmatory evidence comes to hand, 1 

 prefer to use Mr. Taylor's name rathei' 

 than tliat of Ferussac. 



If specifically distinct fi'om V. pyre- 

 naica, this shell is unknown outside 

 Ireland. Ferussac's species is recorded 

 by Jordan from the Pyrenees, in both 

 France and Spain, as being found in his 

 Mountain, Sub-alpine, and Alpine 

 regions, which lie between the alti- 

 tudes of 500-1000, 1000-2000, and 

 over 2000 metres respectively.

 existence of any such species as V. pyreniiicn
