128 A LIST OF LAND A\D FRESH-WATER SHELLS, 



but still there are many specimens to be taken in a season. H. Semele, (the 

 Grayling,) is not a common Butterfly about here: it is to be taken on Haldon, 

 in stony places, particularly Little Haldon, at the back of Dawlish, in a 

 gravel-pit. Hip. Oalathea, (Marbled White:) I have heard of this beautiful 

 ■fly being taken at Teignmouth, but I have not had the chance of seeing it. 



Hip. Tithonus, (Large Heath,) is very common in meadows, etc. Hip. 

 Janira is also very plentiful. Hip. Hyperanthus, (the Ringlet,) is not very 

 common, but many specimens are to be taken in a season, on Haldon. There 

 are several vacancies which occur here in my cabinet to be filled up some time or 

 other, should I be spared. Hip. Pamphilus, (Small Heath,) is tolerable plen- 

 tiful on Haldon and Stoke wood, but not so common as in Norfolk, on 

 Mausehold heath, near Norwich; there I have seen it in great abundance. 

 The Silver Ringlet we cannot boast, so far as I am aware. 



My paper I fear is already too long, so that I must reserve the rest of 

 the Butterflies for another paper,

A LIST OF LAND AND FRESH-WATER 

 SHELLS FOUND IN THE NEIGHBOURHOOD OF PLYMOUTH. 



BY MISS SARAH S. BOLTOX. 



AxTHfJDiNG to the useful hint of W^. C. Unwin, Esq., advanced by him in 

 his List of Land and Fresh-water Shells, page 64 of "The Naturalist" for 

 March, 1853, I endeavour to write a list of such as I have observed in 

 the neighbourhood of Plymouth, and though I am aware the list will be 

 incomplete, yet as no previous catalogue from this locality has been forwarded 

 to "The Naturalist," mine may not be unacceptable, and I hope by the 

 end of the year to add to my list. 



Nomenclature, Gray's Turton, (1840.) 



Littorina rauriatica. Gray. — Inhab., near small streams on the clifiFs above 

 high- water mark, at Whitsand Bay and Wembury: abundant. 



Bithinia ventricosa, Gray. — Water near Antony: plentiful. 



Vitrina pellucida, Drap. — Among decayed leaves, in hedge banks, and 

 under moss at the roots of trees: of frequent occurrence, but not plentiful. 



Helix aspersa, Midler. — Everywhere: specimens near the sea paler and 

 somewhat more solid. 



Helix hortensis. Lister. — Very plentiful in every hedge-row. 



Helix nemoralis, Linn. — In hedge banks, and on slate and limestone rocks, 

 plentiful. Specimens occasionally occur with the peristome white. 



Helix pulchella, Muller. — At the roots of grass on the slopes of the Hoe.
