H. (Chilotrema) lapicida, L. — Local. Plentiful on a wall at Mans- 

 field Woodhouse ; Pleasley ; Southwell, one dead shell and fragments 

 of another ; Kirkby-in-Ashfield, one dead shell. Musson. I have 

 gathered this species freely at Creswell, and have found dead examples 

 from time to time in the road between Tuxford and Egmanton. The 

 presence of dead shells in so many localities where it is not now found 

 living seems to indicate the dying out of the species in this county ? 

 except in a few especially favorable localities.
