Tracy). Breeds in Derbyshire, Lancashire, Yorkshire, and in 
every county north of lat. 54°, reaching the Outer Hebrides and 
Orkneys, but not occurring in Shetland. 
Lacorus ALBus (Bote). Ptarmigan. 
Provinces [VII.?] [XII.] XIV.? XV—XVIII. 
Subprovinees (18 ?), (25), 28 ?, 29, 32-36, (37). 
Lat. 55°-59°.  “ Highland” type. Not in Ireland. 
At present the Ptarmigan is confined to Scotland, though there 
are records of its having formerly inhabited Westmoreland and 
Cumberland. (See Pennant and other earlier writers.) 
Heysham describes the Ptarmigan as having become, in his 
time, very scarce in Cumberland ; and he cites “the lofty moun- 
tains about Keswick ” as the only locality known to him. 
There is a tradition of its former existence in Wales, but I 
have not been able to discover the original authority for this 
statement, which is repeated by both Macgillivray and Thomp- 
son, and in Graves’s ‘ British Ornithology.’ 
My valued correspondent, Dr. J. A. Smith of Edinburgh, has 
copied for me, from a newspaper, a paragraph stating that the 
Ptarmigan inhabits the county of Peebles; but this is the only 
authority for its occurrence so far south on the mainland at 
present. The bird inhabits Islay and Jura (Thompson, B. Brit. 
ii. p. 45), Mull (Mr. H. D. Graham), Dumbarton (Mr. R. Gray), 
Argyle, Perth, and all the counties northward. Mr. John Mac- 
gillivray found the Ptarmigan sparingly in South Uist, and it 
has only recently been exterminated in Hoy. 
Perprx crnEREA (Lath.). Common Partridge. 
Provinces I.—XVII. 
Subprovinces 1-35. 
Lat. 50°-59°.  “ British ” type, or general. 
Throughout Great Britain, being only less common where the 
land has not been brought into cultivation. 
The Partridge is probably a colonist in the northern portion 
of its present range, having followed the progress of tillage.
