164 PROCEEDINGS OF THE ACADEMY OF [May-Oct., 



Theba pyramidata (Drap.) Risso (74). Risso's specimens belong 

 to the Helix suhpyramidata Caziot. The typical ■pyramidata is local- 

 ized to the north of Villefranche-sur-Mer. 



Theba conspurcata (Drap.) Risso (74). Correct. 



Theba carthusiana (Drap.) Risso (74). Correct. 



Theba carthusianella (Drap.) Risso (75). Bourguignat re- 

 marks that H. carthusiana M tiller (1774) should not be confused with 

 Draparnaud's species of the same name (1805) which, he says, should 

 be referred to H. cantiana Montagu. I regard this as an error. The 

 H. cantiana is a northern species of which the variety 7ninor has a 

 striking analogy with the H. rubella Risso, while the H. carthusianella 

 of Draparnaud is a minor variety of his H. carthusiana. 



Theba cemenelea Risso (75). Two species were placed by Risso 

 in this carton, the second of which is H. carthisiana Miiller. 



Theba rubella Risso (75). The specimens agree well with his 

 description. 



Theba charpentiera Risso (76) . This is a dirty white or yellow- 

 ish ash colored variety of the Helix rubella. 



Theba meridionalis Risso (76). Young specimens of Helix ver- 

 miculata Miiller. 



Theba lucostoma Risso (76). Young examples of Helix pisana 

 Miiller. 



Cochlicella ventrosa (Drap.) Risso (77). This species is syn- 

 onymous with Helix acuta Miiller. 



Cochlicella tenuis Risso (77). Smaller and darker specimens 

 of the last mentioned. 



Cochlicella meridionalis (Drap.) Risso (78, fig. 26). Very 

 large specimens of Helix barbara Linne, which Bourguignat has con- 

 fused with H. acuta. 



Cochlicella turricula (Drap.) Risso (78). These specimens 

 have disappeared from the collection. According to Bourguignat 

 they were smaller banded specimens of H. barbara. 



Bulimulus radiatus (L.) Risso (78). The Buliminus radiaius 

 is found locally, in the northern part of the Department. 



RUMINA Risso (79). Rumina decollata (L.) Risso (79). This 

 is the Bulimus decollaius of Bruguiere.
