H. virgata Da Costa. Sandhills. Most abundant west of 

 Coatham. 



H. caperata Mont. Sandhills; most abundant E. of Redcar, 



H. caperata var. ornata. One specimen on Coatham 

 Sandhills. 



H. ericetorum Mlill. With last two species but much less

P. marginata Drap. Extremely abundant from Redcar to 

 Marske, and occurs more sparingly from Redcar to Tees' mouth. 

 Dead shells, beautifully cleared of their contents by insects, are 

 drifted by the wind from the vegetation above into the smooth 

 combes of the sand banks where they may be gathered. by 

 thousands, many in beautiful cabinet condition. I examined 

 carefully with a lens for var. bigj-anata, but my patience failed at 

 the 400th with only one incipient case to repay. 



Vertigo pygmsea Drap. East of Redcar; Wilton Wood, 

 very sparingly. 



V. edentula Drap. Not uncommon in Wilton Wood.
