GEOGRAPHICAL PROVINCES. 
A correspondent who proposes to work 
out the geographical distribution of our 
Geometrina asks for some hints on 
the subject of Areas of Distribution 
or Provinces. 
Mr. Watson, in his 4 Cybele Britan- 
nica,’ divides Great Britain into 18 Pro- 
vinces, and these are the areas referred 
to by Messrs. Boyd and More, in their 
paper in the 4 Zoologist’ of last year. 
As all our readers may not have 
access to Mr. Watson’s work, nor even 
to the 4 Zoologist,’ we recapitulate here 
these 18 Provinces: — 
1. Peninsula: Cornwall, Devon, Somer- 
set. 
2. Channel : Dorset, Wilts, Isle of 
Wight, Hants, Sussex. 
3. Thames: Kent, Surrey, Berks, Ox- 
ford, Bucks, Middlesex, Herts, 
Essex. 
4. Ouse: Suffolk, Norfolk, Cambridge, 
Bedford, Huntingdon, North- 
ampton. 
5. Severn: Gloucester, Worcester, War- 
wick, Stafford, Salop, Hereford, 
Monmouth. 
6. South Wales: Glamorgan, Caer- 
marthen, Pembroke, Cardigan, 
Brecon, Radnor. 
7. North Wales : Montgomery, Me- 
rioneth, Caernarvon, Denbigh, 
Flint, Anglesea. 
8. Trent: Leicester, Rutland, Lincoln, 
Notts, Derby. 
9. Mersey : Cheshire, Lancashire. 
10. Humber: York. 
11. Tyne: Durham, Northumberland. 
12. Lakes: Westmoreland, Cumberland 
(Isle of Man). 
13. West Lowlands: Dumfries, Kirk- 
cudbright, Wigton, Ayr, Lanark, 
Renfrew. 
14. East Lowlands : Berwick, Roxburgh, 
Peebles, Selkirk, Haddington, 
Edinburgh, Linlithgow. 
15. East Highlands: Fife, Kinross, 
Clackmannan, Stirling, Perth, 
Forfar, Kincardine, Aberdeen, 
Banff, Moray (including Nairn, 
Elgin and the North-East of In- 
verness). 
16. West Highlands: Dumbarton, Ar- 
gyll, Inverness (westward of Loch 
Erricht), Isles adjacent from Ar- 
ran to Skye. 
17. North Highlands: Ross, Cromarty, 
Sutherland and Caithness. 
18. North Isles : Hebrides, Orkney, Shet- 
land. 
Now we certainly would not advise 
any one to attempt to make more Pro- 
vinces than those here cited ; probably 
it would be wiser to throw some of 
these together, but that must of course 
depend very much on the actual distri- 
bution of the species. It might be 
simpler to divide only according to 
latitude, and to combine I, 2 and 3, 
4, 5 and 8, keeping Wales distinct, 
9 and 10, 11 and 12, 13 and 14, 
15 and 16; but of course if it prac- 
tically appeared that some species
