40 Mr. A. G. More on the Distribution of Birds 
Subprovinces 1, 2, (3), 4, 5, (6), (7), 16, 17, 18, 25, 26, 27, 
28, 32, 33, 34, 35, 36. 
Lat. 50°-59°. “Atlantic ”’ type. 
On the rocky headlands of the south and west coasts, from 
the Isle of Wight to Ross and Sutherland, in which latter 
county Mr. Dunbar tells me that it inhabits only a few localities. 
Formerly nested on Dover cliffs, according to Pennant, who 
states that a pair brought from Cornwall escaped and stocked 
these rocks, though the well-known passage from Shakspeare 
seems to imply an earlier origin. 
The species is believed to be now extinct in Sussex and Kent, 
and very few pairs now remain in the Isle of Wight, and 
at Purbeck. On the east coast, a few birds only are known 
to breed about St. Abb’s Head and near Fast Castle in Ber- 
wickshire. 
Though not strictly south-western, its much greater preva- 
lence on the western side of the island, and its southern distri- 
bution on the Continent, induce me to refer the Chough to the 
“ Atlantic” rather than to the “ British” type. 
Corvus corax (Linn.). Raven. 
Provinces I.-X VIII. 
Subprovinces 1-38. 
Lat. 50°-61°. “ British ” type, or general. 
Thinly scattered throughout Great Britain, being more nume- 
rous in the north and very scarce in the more level and cul- 
tivated districts. The Raven is already nearly extirpated in 
many of the midland and eastern counties, and is not included 
in either of the two lists which I have received from Lincoln- 
shire. 
Corvus corone (Linn.). Carrion-Crow. 
Provinces I.—X VIII. 
Subprovinces 1-82, 35, 36. 
Lat. 50°-59°. “ British ” type, or general. 
Frequent in England, becoming rare in the middle and north 
of Scotland, where its place is supplied by the Hooded Crow. 
Mr. T, Edward, however, considers the two birds about equally
