The relations of the present genus are not very clear. The only species that occurs within our area approaches Arboricola in Coloration, but the structure is very different and resembles that of Galloperdix. The claws are of moderate length and curved; the tarsus is considerably longer than the middle toe and claw. The tail, of 14 feathers, is more than three-quarters the length of the wing, and is distinctly graduated, the outer feathers being about two-thirds the length of the middle pair. The wing is of the pheasant type and greatly rounded, the 1st primary much shorter than the 10th, 5th usually longest. The males and sometimes the females have a spur on each tarsus. Sexes alike.
Three species are known—one from Formosa, one from Southern China, and the third from the hills of Northern Burma and Assam.
