the district are also given. Of the seventy-five species of the 



former list, seven were mentioned as peculiar to Westmorland ; 



one of these, Pupa marginata, I have since found in Cumberland 



— the number is therefore reduced to six. In the following list 



the species and varieties new to Cumberland and Westmorland 



are marked with an asterisk. 



Pisidiimifo7itinale, Drap. Pond at Corby. 



Anodonta cygnea, L. I obtained one specimen from ^ickerby Beck. The 

 shell is not fully grown, and it is thinner than those found in the 

 Petteril at Wreay, though it ia of a similar olive brown colour. 



*A. anatina, L. Eiver Petteril at Wreay. The shell is beautifully rayed 

 with green. 



Limncea peregra, var. laciistris, Leacli. Mr. Madison of Birmingham has 

 found this shell in Windermere. 



L. peregra, var. ovata, Drap. I found some small specimens of L. peregra 

 in a pond at Blaithwaite, of which the shell is thin, spire short, 

 and the mouth is large in proportion to the size. I sent some to 

 Mr. W. Nelson of Leeds, and he cossiders them to be dwarfed 

 forms of the var. ovat<Sii^** ' '• 



Ir. peregra, var. * acmninata. I found large specimens of L. peregra at 

 Moorville and in Rickerby Beck resembling the var. ovata, but 

 having the mouth less expanded, I therefore thought they must be 

 the var. acuminata, and sent some specimens to Mr. W. Nelson, 

 who kindly examined them and confirmed my opinion. 



L. glabra,'SMM\\. Silloth. 



* Ancyhxs jluviatilis, var. albida. Mr. Maddison informs me that this shell 

 is abundant in the river Rothay, near Rydal, and he has kindly 

 given me some specimens. 



Zonites cellarius, var. albida. St. Bees. 



Z. purus. Aid. Headsnook, upon dead leaves in a ditch, associated with 

 Z. crystallimis, Helix aculeata, and H. pygrucea. 



*Z. purus, var. margaritacea, Je£fr. Headsnook, in a ditch, associated with 

 the type form. 



Z. radiatidus,lA\d. Silloth, at the roots of grass on the sandhills. 



Helix aspersa, jMnll. This shell — though rare in the neighbourhood of 

 Carlisle — abounds on St. Bees Head. 



*H. Jdspida, var. suhrufa. Hayton, near Carlisle.
