Two species, one of which is found in the Himalayas and Burma, differ from the other Green Pigeons in having the whole culmen of the upper mandible formed by the horny portion or rhamphotheca, no soft basal area intervening between the hard part and the frontal feathers. There is a small naked area round the eye. The tail is slightly rounded at the end, and the lower tail-coverts extend almost to the end of the tail. The inner web of the third primary is sinuate. The plumage closely resembles that of Osmotreron phayrei, and there is the same difference between the sexes.
