FALCONID E—continued. 
America. 
Archibuteo lagopus var. sancti-johannis.* 
Penn. 
North America generally. 
The American variety differs from the 
European bird, in the jugular spots 
being scattered, instead of confluent 
into a patch; and in being so fre- 
quently found in melanistic plumage. 
(Baird, Brewer, and Ridgway.) 
Aquila chrysaétus.* Linn. 
Thinly scattered over the Northern and 
mountainous parts of North America. 
The American bird is generally darker, 
and perhaps a little larger than the 
European, for it has been proposed the 
variety canadensis. (Baird, Brewer, 
and Ridgway.) 
Haliaétus albicilla.* (L.) Leach. 
Common in Greenland. (Dresser.) 
Europe. 
Archibuteo lagopus.* Gm. (Rough-legged 
Buzzard.) 
Northern Europe, and Northern Asia ; 
migrating to the central, and some- 
times even southern parts. (Dresser.) 
Aquila chrysaétus.* Linn. (Golden Eagle.) 
The whole of Europe, and Northern Asia, 
extending into India, and Northern 
China. (Sharpe.) 
Haliaétus albicilla.* (L.) Leach. (White- 
tailed Eagle.) 
From Northern Europe, as far south as 
the northern half of Africa; and from 
the north of Asia, south to China and 
India. (Dresser.) 
CoLUMBID&, 
Ectopistes migratorius.* Swainson. (Pas- 
senger Pigeon.) 
According to Baird, Brewer, and 
Ridgway, it is found from Hudson’s 
Bay to the Southern United States ; 
-and west to the Great Central Plains. 
Nevada (Ridgway). Cuba (Gundl). 
Ectopistes migratorius. 
One occurred in Fifeshire in 1825. 
(Fleming, Hist. Brit. An., p. 145.) 
One at Royston, Hertfordshire, July, 
1844. (Yarrell, Hist. Birds, Vol. II. 
p- 317.) 
One seen near Tring, Hertfordshire. 
(Yarrell, op. cit.) 
One near Mellerstain, Berwickshire. 
(Turnbull, Birds of East Lothian, p. £1.) 
Degland and Gerbe (Vol IL., p. 13) state 
that Temminck speaks of its having 
been taken in Norway and Russia. 
TETRAONID, 
Lagopus albus.* Vieill. 
Newfoundland, and Arctic North 
America. Rarely in the United 
States. (Dresser.) 
Lagopus albus.* Vieill. (Willow Grouse.) 
Northern Europe; not in _ Britain. 
Northern Asia. (Dresser.) 
Lagopus scoticus.* Lath. (Red Grouse.) 
Only in the British Isles. 
Closely allied to L. albus. 
Lagopus mutus.* Leach. (Common 
Ptarmigan.) 
Found in the mountains of Northern 
Europe, the highlands of Scotland, 
the high mountain ranges of more 
Southern Europe, and the mountains 
of Asia. (Dresser.) 
The black feathers on the breast in 
summer, and the gray in autumn, of L. 
mutus distinguish it from the variety 
rupestris. (Baird, Brewer, and 
Ridgway.)
