Gen. Tetraogallus, Gray. 



Syn. Megaloperdiz, Brandt. — Chonrtka, Motseh. — Oreotetrax, 

 Cabanis. 



Char. — Bill longish, stout, broad ; a small naked patch behind 

 the eye ; wings moderate and somewhat pointed, having the 2nd 

 and 3rd quills the longest; tail ample, moderate, of eighteen 

 feathers ; tarsi short, stout, with a short blunt spur. Of large 

 size — Sexes alike. 



Until recently but one species was recognised in this fine group, 

 but now four very distinct species have been discriminated, and 

 a fifth indicated. They are birds of large size, as large as a 

 Black-cock, of a light mottled grey colour; and they frequent 

 the highest spots close to the snows ; from their large size they 

 are often popularly called Snow-pheasants ; but, from their asso- 

 ciation with the birds of this group, perhaps had better be called 

 Snow-cocks.
