This \7ood Grouse is a native of Nortl.eru Russia, Siberia, and Kanitscliatka, and is fully described by Middendovf c work above
referred to He says: “ Pallas notices that Messra, Schmidt bad distinguished a smaller variety of W'ood Grouse; Stellcr, on lus part, I find,
affinns that tlie Mood Gronse of Kaintsehatka were obviously smaller than those of Siberia and Russia. Tliesc statements
by the fact tliat in Siberia I hai'o met with two varieties of the Cock-of-thc-Wood, i. c„ the one considered as typical
smaller variety ov species living in tlic momitainons regions; and this latter appearing to be the only one existing
Onr species has several distinguishing characteristics, wWcli wc will rcvieiv in order. First, in regard ■
than the European Cock-of-the-Moods, the full-grown bir.l weighing probably not

'I'hcvc is a fine example of a male of this species in the British Museum, w ith even more wl.ite spots upon the wings than were upon those of
the specimen figured in my plate; and in the Paris Museum a very well preserved female. This last resembles closely the female of Tctrao
Urogallns but the wings and back wore very much spotted and mavko.l witli white, _
This species resembles in some degree its near relative, the Tctrao Urogallns, but may easily be distingnishcd from it by tlic vows of white
spots upon the wings, and also sometimes on tlie back, its small size, and wcdge-sliapcd tail.
Tho figures are about tbvcc-foiivtlis the natural size.
