PREHISTORIC EUROPE. 



I shall refer to only one other example — the fossiliferous 

 breccias of Corsica, which have been described by the same 

 author. 1 He gives a list of nineteen land-shells as occurring hi 

 the breccias which extend along the east coast of the island, 

 from Furiani, south of Bastia, to Cape Corso. They are : — 



Helix aspersa, MiilL 



„ aperta, Born. 



„ nUculoides, Debaux. 



„ vermiculata, Mull. 



„ Raspaillii, Payr. 



„ broccardiana, Dutailly. 



„ hospitans, Bonelli. 



„ halmyris, Mab. 



„ variabilis, Drap. 



„ apicina, Fer. 



Helix galloprovincialis, Drap. 



„ hydatina, Fer. 



„ hispida, Mull. 

 Zonites obscuratus, Porro. 



„ Blauneri, Shuttl. 



„ lathyri, Mab. 

 Pupa quadridens, Drap. 



„ cinerea, Drap. 

 Clausilia Kusteri, Kossm. 



All these are still hiving in Corsica, but some of the species 

 which occur very abundantly in the breccia are now met with 

 sparingly in only a few limited localities. Thus, among others, 

 Helix Iroccardiana, which is extremely common throughout the 



Ferussacia lubrica, Miill.
