from L. maxirmis, with, which it has hitherto been confounded. The 

 Eev. B. J. Clarke met with it in Ireland, as is clear from his writings 

 in 1843 ; but it is only of recent years that it has been ranked by name 

 as a member of the British Fauna. It is, however, a very rare species, 

 and has as yet only turned up in solitary examples. There is reason 

 to suspect that it is in these islands a species which affects the western 

 and northern regions, the regions of a high average rainfall, judging 

 from its known Continental range, and the nature of the British 

 localities which have as yet afforded it. Limax arhorum is a species 

 of apparently similar tendencies in its range, and one which seems to 

 be commoner in Ireland and Scotland, and the hill districts of Wales 

 and IS'orth England, than it is in the English midland, southern and 

 eastern counties. 



"With regard to the other Mollusca included in the list, it is to 

 be observed how remarkable it is that Bulimus acutus, which is, in 

 Great Britain, strictly confined to the coast-line, being nowhere found 

 more than a few hundred yards from the sea, should in Ireland occur 

 in inland localities, even so far inland as Athlone — a tendency which 

 has already been noticed by Mr. Thompson. 



We may conclude these introductory remarks by stating that we 

 should be glad if Irish jN^aturalists — whether they are conversant or 

 not with the Mollusca — will assist us by sending us specimens from 

 every Irish district possible, in order that we may be able to advance 

 at one and the same time a knowledge of the Irish species, and of the 

 variation and distribution of our British ones. Consignments may be 

 addi-essed to John W. Taylor, Office of the Journal of Conchologij, 

 Hunslet New Eoad, Leeds, or "W. Denison Eoebuck, Sunny Bank, 

 Leeds. 



Testacella maugei, v. viridans, Morelet. 



Waterford. — Two specimens sent, Sept. 21, 1883, from a nursery 

 garden at Waterford.— J". S. Salter. 



It is noteworthy that these — the only Irish specimens of T. 

 maitgei that we have seen — shordd differ completely in colour from 

 the English examples, and should resemble the common form 

 which, according to Morelet, occurs in Portugal.
