hey: mollusca of Derbyshire. 119 



L. peregra. — I think I need not say much about this, only 

 that we have plenty of them and some fine ones too. 



L. auricularia. — Fairly common and very fine at Weston, 

 Chellaston, Little Eaton, and Derby Canals. 



L. stagnalis. — The same remarks apply as for L. auricularia. 

 I have also taken some fine specimens with beautifully re- 

 flected lips. 



L. palustris. — Rather scarce ; I have only found a few speci- 

 mens at Weston. 



L. truncatula. — Sparingly distributed; I have taken it in 

 dried-up horse pond at Wingfield, a semi-aquatic ditch at 

 Chellaston, and near Derby (south side). 



L. glabra. — ^Very scarce ; as yet I have only found two speci- 

 mens from pond in Farnah Hall grounds (near Derby). 



Ancylus fluviatilis. — Found in all the brooks throughout the 

 district. 



A. lacustris. — Not very common, but local; I have taken it 

 in Black Pool at Weston-on-Trent. 



Succinea putris. — Fairly common in the lower portion of the 

 county ; Weston, in osier bed on canal banks, in some 

 cases quite twenty yards from water side, feeding on willows. 



S. elegans. — With S. putris and equally common. 



Vitrina pellucida. — Common at Ambergate, Cromford, Lea 

 Hurst (the seat of Miss Nightingale), Millers-dale, Weston, 

 Markeaton, Duffield, &c. 



Zonites cellarius. — Common enough throughout the district. 



Z. alliarius. — I find this in most places under damp stones 

 and dead leaves throughout the county. 



Z. glaber. — In the same localities as Z. cellarius and Z. alliarius. 



Z. nitidulus. — Fairly common at Sinfin, Chellaston, Weston, 

 Little Eaton, and Willington. Lifting up a piece of old 

 bark from a fallen tree a short time ago at Willington, I 

 found many hundreds of these shells congregated there ; 

 they seemed to be from a few months' old to full-grown 

 and mature shells.
