The birds of this group may be considered the typical Partridges, and amongst them the common English Partridge is a prominent member.
The Tibetan Partridge, the sole Indian species of this group, is of about the same size as the English Partridge", and has many characters in common with it, such as the barred wing, the chestnut tail and the bands on the sides of the body. It has, however, one pair of tail-feathers less. The sexes are similar in plumage and size, and there is no spur on the leg of either the male or the female.
It is not quite satisfactory to retain the English and the Tibetan Partridge in the same genus, inasmuch as these two birds differ in the number of their tail-feathers; but I wish to disturb the nomenclature of the " Catalogue" as little as possible, and I accordingly follow Mr. Ogilvie Grant in placing the Tibetan Partridge in the genus Perdix.
