becoming gradually rarer north of the Arctic circle. I had 

 a fine male brought me which had been caught in a fox-trap. 



ARCHIBUTEO LAGOPUS (Gmel.). 



I frequently saw the Rough-legged Buzzard on the wing 

 near our winter- quarters, but failed to secure a specimen. 



MlLVUS 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. 



FALCO 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 off in its talons. On 

 the tundra they were breeding on the steep mud-cliffs on 

 the banks of the Yen-e-say'. In lat. 69| 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 along 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. 



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
