(Phasianidae; Ϯ Sand Partridge A. heyi) Gr. αμμος ammos sand; περδιξ perdix, περδικος perdikos partridge; "AMMOPERDIX HEYI. Hey's Sand Partridge. ... This beautiful little Partridge inhabits the extensive plains and rocky districts of Arabia, and doubtless extends its range to the confines of Persia, and there inosculates with the Ammoperdix Bonhami. The merit of its discovery is due to M. Hey, the companion of that intrepid traveller Dr. Rüppell; and that of first making it known to science to the veteran ornithologist M. Temminck, who assigned to it the specific name of Heyi as a just compliment to its discoverer, and who has published in his "Planches Coloriées" an excellent figure and description of it from specimens killed by M. Hey in the deserts of Acaba in Arabia." (Gould 1851); "Ammoperdix Gould, Bds. Asia, pt. 3, 1851, pl. 4, 5 and text. Type, by subsequent designation, Perdix heyi Temminck. (Reichenbach, Av. Syst. Nat., 1852 (1853), p. xxviii.)" (Peters 1934, II, 59).
