excalfactoria Bonaparte, C. R., xlii, p. 881 (1856).
Type, Tetrao chinensis Linn.
This genus is very close to Coturnix but. whereas in that genus the sexes are very nearly alike in Excalfactoria whilst the female is very like Coturnix, the male is an extremely handsome little bird of striking colours.
The tail has only 8 feathers, short and soft, as against 10 or 12 in Coturnix; the wing is rather short but not much rounded, the first primary a little shorter than the second aud the third the longest; the tarsi are fairly strong but have no spurs.
