The commonest perching bird at Emma Harbor. — 0. A. 



71. EMBERIZA PALLASI (Cabanis). 



One male, 7 miles north of Nijni Kolymsk, June 9, 1915. 

 It measures — wing, 71.5; tail, 59; culmen, 9.5. 



72. EMBERIZA PUSILLA Pallas. 



Two males, Nijni Kolymsk, June 10 and 27, 1915. 

 These measures as follows: Wing, 73-69.5; tail, 

 culmen, 9.5. 



Family CORVIDAE. 



57-54; 



73. CORVUS CORAX KAMTSCHATICUS Dybowski. 



One (" female" ?), Verkhni Kolymsk, April 20, 1915. 



It measures — wing, 415 ; tail, 238.5 ; culmen, 69. Counting from 

 the outside, the third and fourth primaries are longest, the third 

 longer than the fifth. 



Compared with C c. hehringianus, G. c. hamtschaticus appears to 

 be of a deeper black and the gloss of a different shade of purple 

 (more steely) but I attribute these differences to season; C. c. 

 hehringianus has a heavier bill, however. A male of C. c. ussurianus 

 from I-mien-po, Manchuria, October 14, 1914, before me, agrees very 

 well with C. c. kamtschaticus in color, but has a shorter and weaker 

 bill. It measures — wing, 410 ; tail, 257 ; culmen, 62.5. 



As Stresemann ^ has shown, Corvus corax sibiricus Taczanowski, 

 1891, can not be used on account of Corvus sibiricus Boddaert, 1783, 

 and Gmelin, 1788. I therefore follow Buturlin^ in using C. c. 

 kamtschaticus Dybowski for the eastern Siberian form. 



We saw ravens along the coast of the Chorchee Peninsula. They are found 

 throughout the Kolyma Valley, especially in the upper part. — C. A. 



74. CORVUS CORONE ORIENTALIS Eversmann. 



One female, Nijni Kolymsk, October 1, 1914. 



This specimen agrees fairly well with a female bird from Tientsin, 

 China, February 26, except it has a slightly longer bill. From 

 Kamtschatcan specimens it differs in the same way that the raven
