NEW RECORDS FOR BEDFORDSHIRE. 



By E. D. MARQUAND, A.L.S. 



(Read before the Society, May 8th, 1912). 



During a couple of months' shell-collecting with my wife and son in 

 the immediate neighbourhood of Bedford last autumn, we were so 

 fortunate as to discover no less than eleven species which are not 

 included among the recorded moUusca of Bedfordshire. 



Although this is one of the smallest counties in England, it is by 

 no means a poor one in moUuscan life; so that these additions are 

 interesting, even though they do not comprise anything very remark- 

 able. Voucher specimens of all of them have been submitted to the 

 Hon. Recorder, Mr. W. Denison Roebuck, F.L.S., who informs me 

 that the number of land and freshwater shells recorded for this county 

 is now raised to eighty-seven species. 



Euconulus fulvus Mull. — Two specimens on the riverside at 

 Goldington ; " one being unusually large, 3^ mm. diam.X3 mm. alt. 

 One in a copse at Ravensden. More plentiful in an osier bed at 

 Fenlake. 



Punctum pygmaeum Drap. — One under a roadside stone at 

 Renhold. 



Pyramidula rupestris Drap. — Abundant on an old wall on the 

 outskirts of Bedford, in company with Balea perversa. 



Acanthinula aculeata Miill.-- -Six or eight specimens in various 

 places near Bedford. 



Vallonia COStata Miill. — Much more common in this neighbour- 

 hood than its near ally V. pulchella. 



Balea perversa Lin. — Plentiful on an old wall on the south side 

 of Bedford. 



Ancylus fluviatilis Miill. — Three specimens in the River Ouse 

 on stems and leaves, all belonging to the var. alba. One much larger 

 example at Oakley Bridge. 



Planorbis spirorbis Lin. — Two alive in a pool on Goldington 

 Green ; a few dead shells among river debris. 



Vivipara contecta Mill. — Marshes at Kempston and Cardington. 



Bythinia leachii Shep. — Occasional in the river and in marshes, 

 often in company with B. tentaculata.
