Nostrils naked, very large, occupying one half the length of the bill. Wings rounded. Tail broad, rounded, larger and longer than in Perdix; the feathers very soft. Feathers of the back and rump with the shafts thickened, and apparently spinous, as in Ceblepyris. Tarsus shorter than the middle toe. Lateral toes nearly equal. Africa and India. P. erythrorynchus.
