Is nearly related to B. ferox and bears much the same 

 relation to that species as B. mdgaris does to B. desertorum. 



In habits also it resembles that species, and is generally to 

 be met with in the open country. It breeds commonly in south- 

 eastern Siberia, in Dauria on the steppes near the Onon river, 

 and in the vicinity of Argoun, the nest being placed on a rock. 

 The eggs 2 to 4 in number are usually deposited in May and 

 vary, from white very sparingly marked, to bluish white or white 

 with a faint reddish tinge richly spotted and blotched with 

 reddish brown, and in size average 2'44 by T92.
