THE PINK-NECKED GREEN" PIGEON. 309 



by the form of the bill from Treron, and by the colour of the legs from 

 Crocopus. 



There will be no difficulty found, I think, in discriminating the males 

 of the four species of Osmotreron that occur in Burmah ; with the females, 

 however, it is different, as they are all very similar. The following remarks 

 may facilitate the identification of the females. The first two have the 

 head green and the central tail-feathers ashy ; and whereas 0. bicincta has 

 ;ui ashy collar on the nape and hind neck, O. vernans has the whole head 

 and neck green. In the other two species the head is grey and the central 

 tail-feathers green ; and while in O. phayrii the head is pale bluish grey 

 and the wing more than six inches in length, in O. fulvicollis the head is 

 slaty grey and the wing less than six inches in length.
