MISCELLANEOUS. 



SHROPSHIRE MOLLUSCA. 



To the Editors of the Annals of Natural History. 



58 Montagu Square, London, 

 12th Nov. 1855. 

 Gentlemen, — In the fourth volume of your excellent publication 

 (for 1840) is contained a contribution by Mr. Eyton, under the title 

 of " An Attempt to ascertain the Fauna of Shropshire and North 

 Wales." It may be interesting to your subscribers and readers in 

 that district, as well as to those naturalists who are desirous of 

 elucidating the question of geographical distribution, if Mr. Eyton's 

 list of Mollusca were made more complete ; and this I have had lately 

 the opportunity of doing, by a month's residence in the picturesque 

 localitv of Stretton in Shropshire. I subjoin a list of species then 

 found by me, but not mentioned by Mr. Eyton : — 



Pisidium pulchellum. Pupa umbilicata. 



Zonites alliarius, and var. alba. Vertigo edentula. 



Being altogether 22, in addition to 32 species of land and fresh- 

 water shells previously recorded by Mr. Eyton as Salopian. The 

 entire list of British species probably contains double the number, 

 or 108. 



I may add, that I also found a single specimen of that local species, 

 Limneeus ylaher, at Bomere. 



I am, Gentlemen, yours faithfully, 



J. GwYN Jeffreys.
