This genus is scarcely separable from Coturnix, which the female closely resembles. The sexes, however, differ much in their lower plumage, and the cock is a much handsomer bird than the true Quails. The wing is slightly more rounded than in Coturnix; the 1st primary being, as a rule, rather shorter than the second, and there are only 8 short tail-feathers entirely hidden by the upper coverts.
This genus inhabits the Oriental region, Australia and Africa. Of the three recorded species one is found in India.
