Erratic Boulders at Bardncv Ahbev. 



COLEOPTERA, 



Gracilis minuta F. in Yorkshire. — As mentioned in an 

 editorial footnote, in reply to a query by Mr. J. F. Musham 

 (' Nat.'. Aug. 1909. p. 303). G. minuta was taken and brought 

 to me last year by Mr. F. Booth, both at Thackley, near Brad- 

 ford, and at Clapham ; and in each case from umbelliferous 

 flowers. In both instances I think, there can be no doubt about 

 the species being indigenous. Mr. Booth diligently secures for 

 me all the species of coleoptera which come in his way when 

 collecting moUusca, and by this means has added many in- 

 teresting species to our local list. 



Some time ago Mr. F. Bamford gave me a number of speci- 

 mens of G. minuta which he had found emerging from some 

 new wooden bobbins at the great silk factory — Lister & Co., 

 Ltd. — at Manningham. In this case I think we must write 

 them clown as probably introduced with the timber from which 

 the bobbins were made. — J. W. Carter, Bradford. 



ERRATIC BOULDERS AT BARDNEY ABBEY. 



F. M. BURTON, F.L.S., F.G.S. 



Ix the excavations at Bardney Abbey which, through the agency 

 of the Rev. C. E. Laing are now being carried out, three boulders 

 are exposed, which had been utilised by the old builders of 

 the Abbey as corner stones in making its foundation. All three 

 are from the Spilsby Sandstone, similar to the four unfossili- 

 ferous boulders recently described by me in this 3^ear's volume 

 of ' The Naturalist,' page 93. 



One of these boulders is a ' squared ' stone let into the N.W. 

 buttress of the Abbey, 3 ft. 11 in. longxift. 4 in. broad and 

 I ft. 4^ in. deep. 



Another, also ' squared,' forms part of the S.W. corner of 

 the Abbe}^ and measures i ft. 9 in. in length x 5 in. in breadth, 

 and is 10 in. deep. 



Close by it is a third small boulder, let in near this last one, 

 which measures i ft. 3 in. x 9 in. 



There is a fourth unworked boulder from the same source — 

 the Spilsby Sandstone — lying imbedded in the open field near 

 the Abbey. This measures 4 ft. 8 in. in length x 3 ft. 4 in. in 

 breadth, and is, probably, about 2 or 3 ft. deep, like the boulders 

 already described in the paper above referred to.
