DEFINITIONS

GALLOPERDIX
(Phasianidae; Ϯ Red Spurfowl G. spadiceus) Portmanteau of genera Gallus Brisson, 1760, fowl, and Perdix Brisson, 1760, partridge; "In the same work [Delessert 1843] are figured and described, or only described  ...  3. As Francolinus Hardwickii, Gray, the Perdix lunulosa, Valenciennes, v. Fr. nivosus, Mag. de Zool., 1840, Ois. pl. 18; if indeed this be not also the Cingalese, Perdix bicalcaratus of Pennant, which I greatly suspect. The form, to which P. spadiceus also belongs, I regard as constituting a very distinct genus — Galloperdix, Nobis." (Blyth 1844); "Galloperdix Blyth, Journ. As. Soc. Bengal, 13, pt. 2, 1844, p. 936, note. Type, by monotypy, P. spadiceus = Tetrao spadicea Gmelin." (Peters, 1934, II, p. 106).
Synon. Hepburnia, Plectroperdix.
