Woods of the southern counties. Dr. Rutty, in his 

 Natural History of the County of Dublin, gives this as an 

 Irish shell, not uncommon in his time 5 but it has not been 

 found of late. Mr. Dillwyn remarks that the margin of 

 the aperture is slightly margined, which we have not ob- 

 served in the many specimens under our examination, alt 

 of which were, however, dead. v. m.
