These species have extended their range in the Leeds 

 district. Vertigo pusilla has been found at Spofforth, thus 

 \erifying a record of forty years ago. Limncea peregra seems 

 to be decreasing in numbers in the Wharfe at Arthington, 

 while Paludestrina jenkinsi is multiplying rapidly. Outside 

 the Leeds area, but of interest, are Acanihinnla lamellata and 

 a white specimen of Clansilia laminata from Castle Howard. —
