whole of the breast, belly, and underparts are white, most of the 

 feathers of the former mottled with black at the tip ; under tail- 

 coverts black, with wide white tips and white shafts ; the tail-

 marked. Total length 35 inches, wing 15-2, tail 12-2, tarsus 2-9. 



Numerous examples in every intermediate stage of plumage 

 between T. urogallus and the subspecies T. uralensis are to be met 

 with in the London market, but I have been unable to find out 

 what part of Eussia they come from. 



Adult female. Resembles the female of T. urogallus., but is much 

 paler, aU the rufous-buff markings in the latter being yellowish 

 buff, and the white tips to the feathers, especially the scapulars and 

 secondaries, more marked. Total length 24 inches, wing 11*3, 

 tail 7-2, tarsus 2-2.
