The Irish La^id and Freshwater Molhisca. 107 



Helix fusca, Mont. 

 I. II. — IV. V. VI. VII. VIII. — X. — XII. 



This species has been taken in the more mountainous districts of 

 Ireland. 



Foreign Distribution. — This is rather remarkable, the species being 

 a decidedly western European form which has hitherto only been found 

 in the south, south-west, and north of England, Wales, and Scotland. 

 Beyond Great Britain it is known only from the south-west of France. 



(Helix cantiana, Mont.) 



In Walsh and Whitelaw's "History of Dublin," this species is men- 

 tioned as occurring in the neighbourhood of Dublin, and Mr. Taylor 

 received specimens which were said to have been taken in Stillorgan 

 Park, near Dublin, but nevertheless I am disinclined to admit it in the 

 Irish list, as both Mr. Redding and myself scoured every corner of the 

 park, without being able to find a trace of the shell. It has not been re- 

 corded from any other Irish locality. 



Foreign Distribution. — England (chiefly east), near Bremen (Ger- 

 many), Belgium, and north-west France. 



Helix arbustorum, Linn. 

 I?___V.? — — — — — — XII. 



Thompson (15) found this species abundantl}^ in Antrim, and sparingly 

 in Down, but I am doubtful whether the other Irish localities mentioned 

 by him should be regarded as properly authenticated, Irish collectors not 

 being familiar with the look of this species. The late Mr. Warren had 

 young K. aspersa in his collection marked H. arbustorum, and no recent 

 observer has been able to find the species anywhere near Dublin. 



Foreign Distribution. — Great Britain, Germany, France, the Alps 

 up to 7,000 feet, northern Italy, Pyrennees, Scandinavia, Austria, Tran- 

 sylvania. 



Helix pisana, Miill. 



This species inhabits a short track along the coast, between Drogheda 

 (Co. Meath) and the village of Rush (Co. Dublin), and Miss Smith has also 

 found it a few miles north of the Boyne, in Louth. It is absent from the 

 rest of Ireland, the record of Mr. Andrews (15) in Kerry not having been 

 confirmed by later observers. 



Foreign Distribution.— South-west England and Wales, central and 

 southern France, Spain, Portugal, Morocco, Algiers, Tunis, Egypt, Syria, 

 Corsica, Italy, Istria, Greece, Turkey, Cyprus, Madeira, Canaries, and 

 Azores. 



Helix virgata, Da Costa. 

 I. II. III. IV. V. — VII. VIII. — — — XII. 



This very variable species is extremely common in many localities 

 round the coast, and alter a shower of rain it sometimes appears in such 

 unusual numbers, having previously been hidden in the ground, that it 

 has given rise to a popular belief that it has " rained snails." 



Foreign Distribution. — Great Britain (as far north as the south of 

 Scotland), France, Italy, Dalmatia, Portugal, Algiers, Sicily, and Corsica. 



Helix intersecta, Poir. 



I. II. III. IV. V. — — — IX. — — XII. 



H. caperata, Mont, is a more recent name for the same species. In the 

 Co. Dublin, on the limestone of Portmarnock, as well as on the granite of
