(Phasianidae; Ϯ Chestnut-throated Partridge T. obscurus) Genus Tetraogallus J. Gray, 1832, snowcock; Mod. L. phasis pheasant < Med. L. phasis avis pheasant; "TETRAOPHASIS OBSCURUS. MOU-PIN PHEASANT. LOPHOPHORUS OBSCURUS, J. Verr. Archiv. du Mus. Paris (1870), p. 35. HAB. Thibet (DAVID). THIS curious bird is one of the late discoveries of the French missionary Père David, and was described by M. Jules Verreaux, in the Archives of the Museum of Paris, as Lophophorus obscurus. It cannot be considered to belong to that genus, although in some characters it resembles its members, but represents an entirely new genus, and apparently connects a portion of the Phasianidæ with the Snow-Partridges or Tetraogalli. Nothing is known about its economy or habits." (Elliot 1871); "Tetraophasis Elliot, Monogr. Phasian., 1, 1871, p. xix, pl.  and text. Type, by original designation and monotypy, Lophophorus obscurus J. Verreaux." (Peters 1934, II, 62). This small group, formerly known as Monal Partridges, is confined to the mountains of central and southwestern China.
