Genus TRERON, Vieill., 1816. 



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 rhampho- 

 theca, 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 Osmo- 

 treron phayrei, and there is the same difference between the sexes.
