CHELURA TEREBANS. 507 



the jetty in Kingston Harbour, by Mr. Mullins, C. E., 

 who gave an account of it in a paper read before the 

 Institute of Civil Engineers, Ireland ; from the same 

 neighbourhood the late Mr. Robert Ball had obtained it 

 some years previously. It has since been sent to us 

 from Polperro, by Mr. Loughrin ; from Falmouth, where 

 it was found by the Rev. A. M. Norman, who, as well 

 as Major Martin, and the Rev. Dr. Lansborough, found 

 it in Ardrossan Harbour on the Ayreshire coast. We 

 have taken it at the entrance of the Hamoaze, Plymouth. 

 Mr. Thompson took it in Belfast Bay, and Mr. H. 

 Pownall has sent it to us from the Southampton Water. 

 It is, indeed, probably to be found associated with Lim- 

 noria, all round the coasts of Southern and Western 

 Europe, as well as the shores of North America. 



Our friend, Mr. Townshend, who was recently sent by 

 our Government to visit the dockyards of the West India 

 Islands and North America, and who gave considerable 

 attention to the ravages of animals upon submarine 

 timber, informs us that the only wood which resisted 

 the influence of these animals was that of the common 

 Hemlock-tree of the country, and that only as long as 

 the bark remained upon it : but we have recently been 

 informed, by one of the engineers employed at Portland, 

 that the creosoted timber of the jetty, which has existed 

 there for upwards of twenty years, has received no injury 

 from them.
