A List of the Land & Freshwater Shells 
of the District. 
COMPILED BY GEORGE W. SHRUBSOLE 
pia present is the second occasion on which the shells of 
this district have been tabulated. About thirty years ago 
there existed in Chester a Natural History Society, of which 
W. J. Beriars was the Secretary. The best work done by this 
Society was the collection of local shells In 1858, BELLiRs 
published an Illustrated Catalogue of British Land and Fresh- 
water Shells, in which he describes and figures in all 125 species. 
At the present time twenty names on Betxars’ list would 
be regarded either as varieties only, or as doubtful British 
species. They are as follows :— 
DovusTFUL BRITISH SPECIES. VARIETIES.

Limax brunneus is Limax agrestis # 
Clausilia dubia is Clausilia rugosa 3 
Cyclas pusilla var. 
Unio pictorum var. 
Be.iars in his list gives the localities around Chester, in 
which he found, according to our present reading, 61 species. 
The supposed finding of Zimnea auricularis by BELLARS is 
clearly an error; for not only have we failed to find it at the 
locality mentioned, but the figure and descriptive account are 
both faulty. In the latter it is said to be only one-sixth wider, 
instead of double the width of Zimnea peregra. 
The present list contains the names of 93 species and 19 
varieties of Land and Freshwater Shells found in our district. 
The following list has been compiled from local collections, 
which have been sent in from time to time at the Annual 
Conversaziones. 
The initials occurring after the locality indicate the name of 
the. collector, thus—(H.G.B.) Rev. H. G. Barnac tr, Holmes
