This Falcon breeds probably throughout all the steppes, 

 from the Middle Danube to the Altai Mountains, migrating 

 during the winter as far south as Egypt and India. 



I do not know whether this species breeds in Lombardv, but 

 I saw ayoung specimen, obtained in Piedmont, in the Museum 

 of Turin. More to the east it breeds throughout the plains 

 of the Danube (from which I know of two specimens in the 

 Museum of Vienna), and in the Dobrudscha (a specimen in 

 change from the first to the second year's plumage, obtained 

 in the Dobrudscha, is preserved in the collection of Mr. 

 Alleon), in Southern Russia (specimens in the Zoological 

 Museum of Moscow, in my collection, and in the collection 

 of Mr. Severtzov), and in Western Siberia (the Zoological 

 Museum of Moscow and the collection of Mr. Severtzov). 



Some specimens of this species remain all the year round 

 in their breeding-quarters, others migrate southwards during 

 the winter. In the Museum of Vienna I saw some speci- 

 mens of F. leucogenys from Egypt, obtained during the 

 winter near Lake Menzaleh. A specimen obtained at Len- 

 koran (Transcaucasia) is now preserved in my collection. 

 Others, obtained at Chimkent, in the country of the 

 Lower Amou-Darya, near Issyk-kul, and in Ferghana, are 

 to be seen in the Zoological INIuseura of Moscow and in 

 the collection of Mr. Severtzov. Two young specimens, 

 from Babylon and Northern India, I saw in the British
