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 Berwickshire. 



Though not strictly south-western, its much greater prevalence on 

 the western side of the island, and its southern distribution on the 

 Continent, induce me to refer the Chough to the "Atlantic" rather 

 than to the "British" type. 



CORVUS CORAX (Linn.}. Raven.

Thinly scattered throughout Great Britain, being more numerous in 

 the north and very scarce in the more level and cultivated 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 Lincolnshire. 



CORVUS CORONE (Linn.}. Carrion-Crow.

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 numerous in 

 Banffshire. Mr. R. J. Shearer marks the Carrion-Crow as nesting 

 occasionally in Caithness ; and the late Mr. St. John mentions its 

 occurrence in Sutherland, where, however, its nest has not come under 

 the notice of Mr. Dunbar. 



Dr. Dewar informs me that he has seen the Carrion-Crow, during 

 the breeding-season, in the Outer Hebrides, where, as in the neighbour- 

 hood of Glasgow, he believes that it pairs with the Hooded Crow.

Mr. Laver, of Colchester, has informed Dr. C. R. Bree that the 

 ''Dun Crow" occurs in great numbers near the Blackwater River, in 

 Essex, and " some remain and breed there every year. Mr. Laver has
