ADDITIONAL NOTES ON 



THE LAND AND FRESH-WATER SHELLS OF 



CUMBERLAND AND WESTMORLAND. 



By C. W. smith, Penrith, 



It may be interesting to note a few localities, not before recorded, 



for a few of the more uncommon species : — 



Unio margaritifer, L. River Lowther, the finest specimen being 



obtained near Askham. 

 Anodonta cygnea, L. In Old Eden, near Great Salkeld, they seem 



to approach the var. incrassaia, as the shell is more swollen 



and solid. 

 Planorbis nautileus, var. cristata. Edenhali Pond. 

 Linncea J>eregra, var. Candida. In a stream near Edenhali. These 



shells were identified for me through the kindness of Mr. 



George Roberts, of Lofthouse. 

 L. palustris, var. iiftcta. Pond, near Langwathby. 

 L. palustris m. decollatum, Jeff. Langwathby. 

 L. glabra. Miill. I have found this somewhat rare mollusc in a 



pond near Calthwaite railway station, where they are fine 



and abundant. 

 Helix aaileaia, Miill. Near the Iron Bridge, Tirril. 

 H. arbustonim, var. minima, Pfr. Edenhali. 

 H. pulchella, Miill. This small shell is very plentiful on the 

 • limestone at Red Hills, near Penrith, and associated with 

 Bulimus obscurus and H. caperata.
