56 THE CArERCAILLIE. 



otlier outlyinLj localities in the North, South, and West of 

 Scotland, which I have treated of as fully as my materials 

 admit of in the text, but which I have not thought it neces- 

 sary to include in the map. 



This area comprises Perthshire — the head-quarters of the 

 species — Forfar, Fife, Kinross, Clackmannan, Stirling, and 

 Dumbarton; and also the neighbouring portions of Argyle, 

 Inverness, Aberdeen, and Kincardine, in the west and north ; 

 and the Lothians and south shore of the Firth of Forth in the 

 south. 



Those portions coloured an uniform shade of red show the 

 localities where I have ascertained that the species is perma- 

 nently established, or where the bii'ds are at present resident. 

 Those other portions, dotted red, show the localities where the 

 species occurs occasionally, breeds sporadically, or only visits 

 at certain seasons. 



Taymouth, the centre of iiestokation, is marked thus, 



• The concentric rings show the distances from the centre, 

 on the scale of 1 inch to 10 miles, the scale of the map. 



The dates of arrival of the species at the various localities 

 are ])rinted in black over the coloured portions. Where a 

 ca])itiil E precedes the date, Estahlishment is recorded.^ 



Oilier localities where successful introductions have been 

 effected — i.e. where Establishment has resulted — are also 

 marked so, Q ; l)ut in the text Tajnnouth is always spoken of 

 as THE CENTRE, wheucc all distances are measured. 



Localities where unsuccessful introductions have been 

 made are indicated by a cross, tlius x . 



^ While many of the dates given are exact, and have been in the first 

 instance carefully recorded, many others must be accepted only as approxi- 

 mate. 1 found it impossible in many cases to obtain exact statisticj? of 

 Arrival or KsUiblishmrnt, and many of the returns 1 have received contained 

 no dates whatever. Such, I think, can hardly be looked for in all cases, but 



1 believe by far the larger number of the dates and statistics given can be relied 

 upon for all practical purposes.
