Helix pomatia. — Charlbury, on the gi-assy banks of the railway 

 cutting. 



Helix pomatia v. albida. — Charlbury, on the gi'assy banks of the 

 railway cutting. The strata here are entirely Oolitic. 



Helix aspersa. — Everywhere abundant. 



Helix nemoralis. — -Everywhere abundant. 



Helix arhustorum. — Cropredy Canal bank, abundant close to the 

 Canal bridge, but exceedingly local, giving place to H. nemoralis 

 within the space of 100 yards. Its presence may possibly be deter- 

 mined by an abundant growth of Angelica Sylvestris at this spot, on 

 which it is found.
