Mr. T. C. Eyton on the Fauna of Shropshire. 397 



species does not coincide with that so called on the continent, has 

 been made known to the world; the name therefore which has been 

 applied to it must be here adopted in the place of that before given ; 

 viz. for S. araneus read S. rusiicus, Jen. 



Sorex tetragonurus, Durer., Jen. (Square-tailed Shrew.) I have 

 lately captured one specimen of this shrew in the marshy meadows 

 bordering the river Tearne between Longdon and Allscot ; its length 

 from the tip of the snout to the root of the tail is 3 inches. 



Arvicola pratensis, Bail. (Bank Vole.) Several times taken near 

 Eyton. 



Sula Bassana, Linn. (Gannet.) A specimen has lately been brought 

 to me alive, caught during a high wind quite exhausted ; it became 

 so tame after a few days that it would take fish from the hand. 



Invertebrata. 

 Land and Freshwater Mollusca. 



Arion ater, Fer. Com<Qon. 



Limax cinereus, Linn. Common. 



Limax agrestis, Linn. Common under stones and logs of wood 

 in autumn. 



Vitrina pellucida, Mull. Common. 



Succinea, Drap. Succinea amphibia, Turton, Manual, and S. am- 

 phibia, Drap., are two distinct shells ; but S. oblonga, Turt., is S. am- 

 phibia, Drap. Helix per egr a, Mont., is not either of these, but ap- 

 pears to be a true Succinea, although quoted by Turton as a synonym 

 to Limneus pereger, but is the shell figured by Pennant under the 

 name of Helix putris. With S. amphibia, Turt., I am unacquainted. 

 The synonyms of the British species of the genus which I have had 

 an opportunity of examining will therefore stand thus : — 



Succinea amphibia, Drap. S. oblonga, Turt. Helix putris, Mont. 

 Not uncommon about Eyton. 



Succinea peregra. Helix peregra, Mont. Helix putris, Peun. Com- 

 mon ; adhering to water plants. 



Helix arbustorum, Linn. Common. 



Helix aspersa, Gmel. Common in many localities, particularly on 

 the walls of Beaumaris Castle, also near Rhoscolyn on Holyhead . 

 Island. 



Helix nemoralis, Linn. Innumerable varieties of this common shell 

 occur. 



Helix hortensis, Linn. Occasionally occurs at Eyton. 



Helix rufescens, Mont. Found on most sand hills near the sea.
