Corvus corone orientalis Eversmann. 

 One youngish male, Tchegan-Burgazi Pass, July 21. 



Nucifraga caryocatactes rothschildi Hartert. 



Six adults, both sexes, Topucha, August 5 to 9. 



The nutcracker of the region I refer, without much doubt, to the 

 above form, of which, however, I have seen no specimens. Our series 

 seems to indicate that the Altai bird is not quite extreme rothschildi 

 but that it tends a little toward N. c. macrorhynchus Brehm. 



Pica pica bactriana Bonaparte. 

 Two females, Tchegan-Burgazi Pass. July 19 and 20. 



Perisoreus infaustus opicus, subsp. nov. 



Three specimens, adult male and female and young male, Topucha, 

 August 8 and 10. 



Type from Topucha, Altai Mountains, Siberia, No. 57,701 adult cf, 

 M. C. Z. Collected, August 8, 1912, by N. Hollister. 



Characters. Similar in general to P. infaustus infaustus (Linne). 

 of northern Europe, but distinguished at once by the pileum, upper 

 cheeks, and lores being black instead of brown; the black cap also 

 abruptly defined against the grayish of the hind neck, whereas in P. i. 

 infaustus the brown cap merges gradually into the color of the hind 

 neck. No comparison, of course, with the large, pale grayish form, 

 P. infaustus sibericus (Boddaert), of east Siberia and Kamchatka is 

 needed. 



Pyrrhocorax pyrrhocorax (Linne). 



Eight specimens, adults and young of both sexes Tchegan-Burgazi 

 Pass. July 1-July 18. The chough was abundant, especially so in 

 the rocky cliffs at about 9,000 feet elevation.
