and Castle Eden-Dean ; in Yorkshire, woods at Castle Howard 
and Kirkhain, Rigby woods near Pontefract, near Ingleton and 
Halifax, about Leeds, Hackfall, near Huby, Laver banks and 
Mackershaw wood, on the banks of the Skell by Ripon ; in

Warwickshire, in a moist ditch near Middleton ; in Cambridge- 
shire, Stretham ferry and Gamlingay bogs ; in Bedfordshire, 
Potton marshes and Ampthill bogs : in Wiltshire, in a rivulet 
near Broadstitch Abbey, plentifully. The same authors have 
recorded two Welch habitats : — in Denbighshire, on the west 
side of the brook that runs from Henllan mill into the river Elwy, 
about 300 yards from Trap bridge, less than a mile from Garm ; 
and in Flintshire, near Maesmynnan. In addition to these lo- 
calities, I am enabled, through the kindness of correspondents, 
to give the following : — in Yorkshire, by the Derwent at Cram- 
beck, and near Raskelf, J. Backhouse, jun.,” Bolton vroods in 
Wharfedale, S. Gibson,” and by the banks of a rivulet in 
Conesthorpe, H. Ibbotson ; ” Lancashire, in small quantities, 
in Mereclough, near Manchester, J. B. Wood Cheshire, ^^Lally’s 
wood, near Over, W. Wilson ; ” Worcestershire, Mosley Bog, 
G. W. Perry;” and Leicestershire, “ Gracedieu, C. Babington.” 
Through the liberality of Dr. Greville, Dr. Balfour and Dr. 
Campbell, T have received specimens from several Scotch habi- 
tats, more particularly the vicinity of Edinburgh ; Mr, Brichan 
has obligingly sent me specimens from the banks of the Dee, 
Kincardineshire ; Mr. Kippist informs me that he has seen it in 
abundance in the woods about Corra Lyn, Lanarkshire ; and 
the Rev. G. Gordon mentions it as very abundant in the bog at 
Pittendriech, in Moray. In Ireland, Mr. Mackay and Mr. 
Moore have found it in the counties Dublin and Wicklow.
