ON THE OCCURRENCE OF HELIX ASPERSA Miiller 

 var. GLABRA Calcara IN MID-LINCOLNSHIRE. 



By J. F. MUSHAM, F.E.S. 



(Read before the Society, Nov. gth, 1910). 



At the meeting of this Society, held on Sept. 14th last, Mr. J. W. 

 Taylor exhibited two specimens of Helix aspersa^ which he found 

 referable to the var. glabra of Calcara, and which were sent him by me. 



They were found quite accidentally in the churchyard of Rand St. 

 Oswald, ten miles north-east of Lincoln, by a friend who was spend- 

 ing the day angling in the beck which runs by the side of the church- 

 yard. 



In one corner of this churchyard was a large irregular heap of 

 stones, the bulk of them cobbles, as the district is gravelly, overgrown 

 more or less with ivy. 



Turning tiie heap over, he found these specimens ; most of them 

 are dead shells, but those which were alive show the same character- 

 istics, so their smoothness can scarcely be attributable entirely to their 

 age, or due to their being partly buried in sand. 



Several youngsters were left on the spot, showing, as far as my 

 friend could judge, every likelihood of growing up like their parents. 

 These, I had hoped, would keep the colony flourishing, but on writing 

 some days ago, after an interval of six months, I received the dis- 

 appointing news that the stone-heap had been cleared away and the 

 adjacent ground levelled, and all trace of the shells removed ; so we 

 may consider it fortunate that this interesting aberration was recorded 

 in time. 



I have not been able to secure more specimens from any other part 

 of the county, but in May last a box oi H. aspersa, similar to these, 

 was sent me from Bracebridge-by-Lincoln Fen. They consist of dead 

 shells of a similar ground colour, but not so glabrous.
