becoming gradually rarer north of the Arctic circle. I had 
a fine male brought me which had been caught in a fox-trap. 
4-Archibuteo lagopus (Gmel.). 
I frequently saw the Rough-legged Buzzard on the wing 
near our winter-quarters, but failed to secure a specimen. 
Milvus MIGRANS (Bodd.). 
I did not notice the Black Kite on the Yen-e-say^ until we 
reached lat. 61° on the return journey. From this point it 
increased in abundance as we proceeded south and west, until 
in Tomsk it swarmed to as great an extent as it does in Con¬ 
stantinople. I did not shoot one of these birds. 
-^ALCO PEREGRINUS, Tunstall. 
The Peregrine Falcon was first seen on the Koo-ray'-i-ka 
about the middle of May; and on the 25th of that month I 
secured a fine male. I once saw one of these birds dash into 
a flock of Snow-Buntings and bear one oflP in its talons. On 
the tundra they were breeding on the steep mud-cliffs on 
the banks of the Yen-e-say'. In lat. 69J° I spent the night 
of the 13th-14th July on shore, shooting. I had no sooner 
landed than a couple of Peregrines showed me their nest by 
their loud cries. A glance at the cliffs decided the place 
where the nest ought to be—on the top of a steep mud pro¬ 
montory, which stretched out to a sharp ridge beyond and above 
the surrounding coast. I climbed up a valley in which the 
snow was still lying, and walked straight aloug the ridge to 
the little hollow where the four red eggs were placed upon a 
dozen small flakes of down. The eggs were considerably 
incubated. 
-f Falco tinnunculus, Linn. 
I did not observe the Kestrel until I reached Yen-e-saisk' 
on my return journey, about the middle of August. The 
banks of the river to the south of the town are very flat; and 
a wide extent of meadow-land, which had recently been cut 
for hay, stretches southward for miles. This plain is sur¬ 
rounded by forests and intersected with numerous half-dried- 
up river-beds running parallel to the Yen-e-say'. In this
