320 ORNITHOLOGICAL EXPLORATIONS. 



Steller is the first author to mention the White Hawk : " Eine beson- 

 dere Sorte weisser Habichte" (Beschr. Kamtsch., p. 194). 

 ? Astur palumbarius (Lin.)- 



Taczauowski (B. S. Z. F., 1883, p. 331), under the heading of Aatur airicapillus, 

 mentions having received a "young female from Bolszeiethk [Bolscheretschk ?], dif- 

 fering from a female from Quebec, in similar plumage, by having the general color 

 much clearer," &c. The identification of this specimen is extremely doubtful; it is 

 probably only a young of A. candidissimus.

 ? Aquila clanga Pallas (Z. R. A., I, p. 351; "usque in Camtschatcam ") is 

 probably the same bird which Steller mentions as " ^aerta " (Beschr. Kamtsch., p. 

 193). But where refer it ?

Scops kavitschatkensia Bp., Rev. et Mag. de Zool., 1854 (p. 543). 

 (Scops jfiMScopoLi. — Sharpe, Brit. Mus. Cat., II, p. 47 (1875). 

 "A French specimen collected by Mr. Swainson is in the Cambridge Museum, and 

 nearly equals in intensity the type of Scops kamtschaikensis in the Paris Museum. I 

 carefully compared this with ordinary European examples, and can affirm with cer- 

 tainty that it is nothing but a more than ordinarily rufous Scops giu; no authority for 

 its Kamtschatkan habitat exists beyond the assertion of the late M. Jules Verreaux. 



" In the Paris Museum there is another specijuen marked as from Kamtschatka, and 

 absolutely identicul with ordinary European specimens." (Sharpe, I. c.pp., 50, 51.) 

 The locality requires confirmation.
