(syn. Arborophila Ϯ Taiwan Hill Partridge A. crudigularis) Gr. ορος oros, ορεος oreos mountain (i.e. mountains of Formosa/Taiwan); περδιξ perdix, περδικος perdikos partridge; "Besides their peculiar red unspurred legs, thick black bill, and very short tail, the most striking peculiarity was in their all having an ugly raw-looking red patch on the throat. ... They are not Arboricolæ, for they are of a different type, and, from their straight claws, certainly non-perching birds. They approach nearest the genus Ciccaba; but from these they differ in the unspurred leg, the short tail, and the thick bill. Therefore, though loth to multiply genera, I see no hope of avoiding it in this case; and, from their being denizens of the interior mountains, I propose to create for them the genus which I will proceed to define. OREOPERDIX, n. gen. ... OREOPERDIX CRUDIGULARIS, n. sp." (Swinhoe 1864).
