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. rusticus, 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. 



Sulci 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. 



IlSWERTEBRATA. 



Land and Freshwater Mollusca. 



Arion ater, Fer. Common. 



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 5. 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, Penn. 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.
