Exhibits : 



On behalf of the Rev. George Gordon, LL.D., was exhibited Hehx 

 caperata from Inverugie, being a new species record for North Aberdeenshire. 



The Recorder exhibited various land and freshwater shells from Settle, 

 Horton-in-Ribblesdale, Rokeby and the Greta, Eggleston Abbey, etc. 



On behalf of Mr. Arthur Mayfield were shown Helix caperata var. alba 

 from Drayton, Ptipa marginata from Ringland, P. umbilicata var. aff. 

 albma from Harlham, and Hyalinia nitidula from Lakenham. 



On behalf of Mr. J. Benj. Beckett was exhibited a piece of wood from 

 a pile of the harbour at Yarmouth, showing the borings of Teredo navalis. 

 At one time the Teredo was a source of great trouble and expense to the 

 Yarmouth Harbour Authorities ; their depredations causing immense 

 damage to the wooden piles, which had continually to be renewed. Now, 

 however, they have almost if not entirely departed from that locality, and 

 Mr. Beckett suggests that this may be accounted for by the fact that of late 

 years the sea at ebb tide has receded further, and has not come up at flood 

 so far as formerly, which of course causes more fresh water to find its way 

 to the mouth of the river. The sewage, too, which is now all turned into 

 the river, may have had some effect upon the Teredo.
