GASTROPODA. 

 P U L M O N A T A . 



Genus— PUPA. 



Pupa anglica, Fer. 



I. II. Ill IV. V. VI. — VIII. IX. X. XI. XII. 



This species, which was formerly believed to be peculiar to the British 

 Islands, is abundant in some localities, but quite absent from others. It 

 is the P. ringens of Jeffreys. 



FoRE^iGN DiSTRiBUTiox. — South-west and north Kngland, Wales and 

 Scotland, Pyrenees, Portugal, and Algiers. 



Pupa cylindracea, Da Costa. 

 I. II. — IV. V. — VII. VIII. IX. X. XI. XII. 



In limestone districts especially this species is extremely common, but 

 it also occurs on pure granite soil. To British conchologists it is perhaps 

 better known by the more recent name of P. iimhilicata, Drap. 



For:e:ign Distribution. — Great Britain, north Germany, south 

 Norway, Sweden, France, Spain, Portugal, Corsica, Sardinia, Sicily, 

 south Austria, north Italy, Dalmatia, Greece, Algiers, Morocco, Azores, 

 Canaries, Madeira, and St. Helena. 



Pupa muscorum, MUller. 

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



P. marginata, Drap., the name adopted by Thompson, is a more recent 

 one than P. muscorum. It is rarer than the preceding ; but Mr. Praeger 

 met with enormous numbers of dead specimens on the sea-shore near 

 Bundoran. I found it on the Aran Islands. 



Foreign Distribution. — Great Britain, throughout continental 

 Europe, Iceland, Corsica, Siberia, Algiers and Morocco, Thibet, Tur- 

 kestan, and North America. 



Genus— VERTIGO. 



Vertigo edentula, Drap. 

 I. — III. IV. V. — VII. VIII. IX. X. — XII. 



It requires most diligent search, especially among fallen leaves, to 

 discover this species, but it is not uncommon in wooded districts. 



Foreign Distribution. — Great Britain, continental Europe (except 

 Portugal), Sicily, Siberia, Azores, Madeira, Canaries, and Alaska. 



Vertigo minutissima, Hartm. 



According to Messrs. Taylor and Roebuck (14), this species has been 

 taken at Killarney by Mr. Hardy, but no other specimen has been 

 found in Ireland. 



Foreign Distribution. — Very local in England and Scotland, 

 throughout Europe, except the extreme north, Algiers, Morocco, and 

 Madeira (sub-fossil).
